Working at Chainguard in 2026: The Security Unicorn Making Open Source Safe by Default

Most security companies sell fear. Chainguard sells prevention. Founded in 2021 by five former Google engineers — Dan Lorenc, Kim Lewandowski, Matt Moore, Scott Nichols, and Ville Aikas — the company has grown from a small open-source security startup to a $3.5 billion enterprise in under four years. The product is deceptively simple: hardened container images, language libraries, and VM images that ship with zero known vulnerabilities by default. Instead of asking engineering teams to patch hundreds of CVEs after deployment, Chainguard eliminates them at the source.

The founding team's pedigree is unusual for a security company. These are the people who built Sigstore (the free signing standard now used across the open-source ecosystem), contributed to Kubernetes and Knative at Google, and helped define modern software supply chain security before it became a boardroom concern. That background — deeply technical, open-source-native, practitioner-first — shapes everything about how Chainguard operates as an employer.

We pulled data from Chainguard's Glassdoor reviews (55 as of early 2026), their public careers page, and community signals to give you an honest picture of what it's actually like to work there. Here's what you need to know.

Chainguard at a Glance

Among the 85 companies in our Culture Directory, Chainguard stands out for the combination of a genuinely technical founding team, rapid hypergrowth, and a culture that still feels more like an open-source project than a corporate security vendor. The 4.5 Glassdoor rating and 90% recommendation rate are strong signals — particularly given that 55 reviews is enough to establish a meaningful pattern rather than just early-employee enthusiasm.

The Founding Story: From Google's Open-Source Team to $3.5B

Chainguard's origin story matters because it explains the culture. In 2020, the SolarWinds hack exposed a fundamental weakness in the software supply chain: even well-run organizations were vulnerable because the open-source components they relied on weren't secure by default. Dan Lorenc, then at Google, had been working on this problem. He'd created Sigstore, a free standard for signing and verifying software artifacts, and had helped build Tekton (a CI/CD framework for Kubernetes). He saw that the industry needed more than just tools for detecting vulnerabilities after the fact — it needed secure-by-default artifacts that never had the vulnerabilities in the first place.

In 2021, Lorenc left Google along with four colleagues — Kim Lewandowski, Matt Moore, Scott Nichols, and Ville Aikas — all of whom had deep roots in Google's open-source infrastructure. Together, they founded Chainguard with a thesis that seemed almost too simple: what if every container image, every language library, every VM image started with zero known CVEs? Not patched after the fact. Not scanned and flagged. Just clean from the start.

The market validated the thesis quickly. Chainguard raised $892M in total funding across multiple rounds, including a $356M Series D in April 2025 and a $280M growth round led by General Catalyst in October 2025. Annual recurring revenue grew from roughly $40M in FY2025 to a projected $100M in FY2026 — 7x growth in a single fiscal year. In a cybersecurity market saturated with noise and fear-based marketing, Chainguard's practitioner-led, open-source-first approach has resonated with engineering teams at companies that buy based on technical merit.

This growth trajectory matters for prospective employees because it defines the current experience. Chainguard is a company that has scaled from startup to enterprise in record time. The culture still reflects the open-source roots and practitioner DNA of the founding team, but the organizational infrastructure is scrambling to catch up with the business. That tension — between the scrappy open-source ethos and the demands of a billion-dollar enterprise — is the defining feature of working at Chainguard right now.

Open-Source DNA: Wolfi, Chainguard Images, and the Culture It Creates

Chainguard is not a company that uses open-source. It is an open-source company. The distinction matters for understanding the culture. Chainguard's core products — Chainguard Images and Wolfi (a Linux "undistro" designed for containers) — are built on open-source foundations. Wolfi itself is fully open-source. The company's approach to container security grew directly out of open-source supply chain work the founders did at Google.

This shapes the engineering culture in tangible ways. Engineers at Chainguard work in the open, contribute to public projects, and engage with a community of practitioners who use and scrutinize their work. The internal culture mirrors open-source norms: technical merit drives decisions, documentation is a first-class artifact, and credibility comes from what you ship rather than your title. For engineers coming from traditional enterprise security companies, this can feel like a breath of fresh air. For those coming from the open-source world itself, it feels like home.

The open-source orientation also means Chainguard attracts a particular type of engineer. The people who thrive here are those who have opinions about supply chain security, who've dealt with CVE triage at 2 AM, who understand why Sigstore matters. The hiring bar is high, but it's calibrated toward practical security knowledge and open-source contribution rather than algorithmic puzzle-solving. If you've maintained a popular open-source project or built infrastructure used by thousands of developers, Chainguard will notice.

Remote-First with Exceptional Benefits

Chainguard has been fully remote since its founding. The company has no central office, and most employees are US-based. This wasn't a pandemic accommodation — it was a deliberate choice by founders who had experienced both the benefits and limitations of Google's office-centric culture and chose differently for their own company.

What sets Chainguard apart from other remote companies is the benefits package. The company offers 100% employer-paid health, dental, and vision insurance — not just for employees, but for their families. In the US healthcare landscape, where family coverage can easily cost $1,500–$2,000+ per month, this is a genuinely meaningful benefit. It's one of the most frequently cited positives in Glassdoor reviews, and it signals something about how the company thinks about employee welfare: not as a retention tactic, but as a baseline.

The work-life balance score of 4.2/5 on Glassdoor is consistent with what you'd expect from a well-run remote company. It's not the 4.5+ you see at smaller, slower-growing companies like PostHog, because Chainguard is in hypergrowth mode. But it's meaningfully higher than the 3.5–3.8 range typical of enterprise security companies. The remote-first model gives people flexibility to structure their days, and the 4.2 rating suggests that flexibility is genuine rather than aspirational.

The downside of fully remote, as several reviewers note, is that it can feel isolating — particularly for employees who joined during rapid scaling phases and haven't yet built strong internal relationships. At ~666 employees, Chainguard is large enough that you won't know everyone, but small enough that remote isolation is more noticeable than it would be at a 5,000-person company with established virtual social infrastructure.

Glassdoor Ratings Breakdown

Chainguard's 4.5 overall Glassdoor rating, based on 55 reviews, is one of the stronger scores across the 85 companies in our directory. It sits alongside companies like Anthropic and above most enterprise security competitors. More importantly, the sub-category scores paint a consistent picture of a company that employees genuinely like working at — with some predictable growing pains.

The Culture & Values score of 4.3 is notable because it reflects a company that has managed to maintain its open-source identity even through hypergrowth. Career Opportunities at 4.3 is strong for a company that's only five years old — the rapid growth means new roles and responsibilities are being created constantly, and employees who joined early have had the opportunity to grow into leadership positions that didn't exist a year ago. The 4.2 Work-Life Balance score, while not exceptional, is solid for a company growing this fast.

The 93% positive business outlook is the number that jumps off the page. In our experience, business outlook above 85% is rare and indicates that employees believe in the company's trajectory, not just its current state. At Chainguard, this likely reflects the combination of massive funding, rapid ARR growth, and a product that solves a genuine problem the market is increasingly willing to pay for.

What Employees Actually Say

The Glassdoor reviews tell a story of a company that gets the big things right but is wrestling with the predictable challenges of scaling at breakneck speed.

What employees love

The consistent theme is authenticity. Employees describe a company where the mission is real (not just marketing), the technical bar is high, and the leadership team is composed of practitioners rather than professional executives. For people coming from traditional enterprise security companies — where sales culture often dominates engineering — Chainguard's engineering-driven approach is a significant draw.

What could be better

The cons deserve honest examination. The "fear-based management" concern that appears in some reviews is worth noting. It's not the dominant sentiment — the 90% recommendation rate and 4.5 overall score indicate that most employees have a positive experience — but it appears often enough that prospective employees should ask pointed questions about management style during the interview process. Hypergrowth companies often have uneven management quality because they promote fast and hire managers externally who may not share the founding culture. Whether this is a systemic issue or a localized one depends on the team you'd be joining.

The split between engineering and sales culture is also worth flagging. At many security companies, sales dominates the culture and engineers feel like an afterthought. At Chainguard, the opposite dynamic can create friction: the practitioner-first, engineering-driven culture is a genuine strength, but it can leave sales teams feeling like second-class citizens. If you're in go-to-market rather than engineering, calibrate your expectations accordingly.

Compensation & Equity

Chainguard's compensation package is competitive, anchored by two standout components: the benefits and the equity.

The equity story at Chainguard is compelling. At a $3.5B valuation with $892M in funding, the company is well-capitalized and growing revenue at 7x annually. For employees receiving equity grants, the question isn't whether Chainguard is a real business (the ARR growth answers that) but how much further the valuation can grow. A company projecting $100M ARR in FY2026 at a $3.5B valuation has a revenue multiple of 35x — high but not unusual for a fast-growing security company. The potential paths to liquidity (IPO or acquisition) are both plausible, which means equity has real potential value rather than being lottery tickets.

The 100% employer-paid health, dental, and vision coverage for employees and families is the benefit that gets mentioned most frequently. In the context of US healthcare costs, this represents thousands of dollars per year in effective additional compensation. Combined with a fully remote work model (no commuting costs), the total value proposition extends well beyond base salary.

Base salaries are competitive with the enterprise security market but likely below the frontier AI labs like Anthropic or OpenAI. The total comp equation depends heavily on how you value the equity component — and at Chainguard's growth rate, that's a bet worth taking seriously.

Who Thrives at Chainguard — and Who Should Be Cautious

Chainguard's culture is specific enough that fit matters significantly. Based on the Glassdoor data, the founding team's background, and the company's operating model, here's who tends to do well:

• Open-source practitioners. If you've maintained public repos, contributed to CNCF projects, or built infrastructure that other developers use, Chainguard's open-source culture will feel natural. The founding team comes from this world, and the culture rewards the same traits: technical rigor, public accountability, and community engagement.
• Security engineers who are tired of fear-based selling. Chainguard's product philosophy is prevention, not detection. If you're burnt out on security companies that sell fear and ship mediocre products, the engineering-driven approach here is genuinely refreshing. The technical problems are real and the product has clear market validation.
• People who thrive in ambiguity. At a company growing 7x annually, processes, org charts, and priorities change constantly. If you need clearly defined roles, stable team structures, and predictable workflows, the current growth phase will feel chaotic. If you see ambiguity as opportunity, you'll find plenty of room to shape the company.
• Remote-native workers. Chainguard has been remote-first from day one. If you've proven you can be productive, communicative, and connected without an office, you'll fit right in. If you secretly prefer in-person collaboration, the fully remote model won't change for you.
• Engineers who want equity upside without sacrificing benefits. The combination of competitive equity at a $3.5B valuation and exceptional benefits is unusual. Most startups make you choose between equity upside and good benefits. Chainguard offers both.

Chainguard is not ideal for people who need organizational stability, clearly defined career ladders, or a culture where every department is treated equally. The engineering-first culture is a feature, not a bug — but it means go-to-market teams may feel like they're working in a different company. If management style consistency is important to you, ask specific questions about your potential manager during interviews. And if you're looking for a slow-paced, settled environment, a company that grew from zero to $3.5B in four years is not that.

Open Positions at Chainguard

Chainguard is actively hiring across engineering, security, and go-to-market roles. As a fully remote company, positions are primarily open to US-based candidates. The combination of rapid growth, strong funding, and the open-source mission described in this post makes Chainguard worth serious consideration for security engineers and infrastructure practitioners who want to work on problems that genuinely matter.
