Pros & Cons
Chainguard
- Fully remote with outstanding benefits — 100% employer-paid insurance for employees and families
- Founders are practitioners who understand what engineers and security teams need
- Growing so fast that some inefficiencies exist, though improving
- Fully remote means you miss in-person interactions with teammates
Mercor
- Massive impact at an AI company growing at breakneck speed
- Top-tier compensation with strong equity at $10B valuation
- Intense 9/9/6 work schedule — long hours are the norm
- Work-life balance is a real sacrifice at this stage
Bottom Line
Chainguard
Choose Chainguard if you want to build supply chain security tools in a remote, open-source-first culture with strong equity — but expect a fast-moving startup pace.
Mercor
Choose Mercor if you want outsized impact on AI-era hiring at a tiny, fast-moving team — but the 9/9/6 schedule is real, and work-life balance is genuinely sacrificed for speed.
