Pros & Cons
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
Tailscale
- Same pay worldwide with 26 weeks parental leave and genuine work-life balance
- Brilliant, nerdy CEO who deeply understands the tech — culture is intellectual and respectful
- Career progression limited — only 3.0/5 on career opportunities
- Middle management still developing — some growing pains as the org scales
Bottom Line
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.
Tailscale
Intellectual, engineer-led culture with same pay worldwide and 26 weeks parental leave — but career progression is limited and middle management is still maturing.
