• Track record of owning and delivering impactful projects autonomously.
• Rigorous approach to correctness, including writing tests, handling edge cases, and thinking through failure modes.
• Ability to navigate ambiguity and drive clarity in complex problem spaces.
• Clear communication skills and the ability to influence technical decisions.

Nice to Have:

• Experience in fintech, payroll, or tax domains.
• Background in compliance-critical systems where correctness is paramount.
