Software Engineer, Tax

What we're looking for 5+ years of professional software engineering experience , with a track record of taking full ownership of projects from spec to ship to scale. Hands-on technical depth in domains where correctness matters. You've shipped real systems where edge cases, accuracy, and domain depth were non-negotiable. Demonstrated ability to bridge engineering and a non-engineering domain. Engineers and tax experts (or doctors, or lawyers, or any deep domain expert) think wildly differently. You've worked closely with non-engineering experts before, taken their judgment seriously, and built shared language and shared artifacts that let both sides do their best work. We've watched smart people struggle here, and this is the part of the job we look at hardest. AI-native fluency. AI tooling is woven into how you work and ship, and you have a clear point of view on where it helps and where it creates noise. Comfortable across the stack. Backend, frontend, or infrastructure — you can reason about whatever the problem actually requires.

Bonus: experience building or contributing to a rules engine, calculation engine, or comparable system. Tax, payroll, billing, pricing, underwriting, claims adjudication, compliance,

benefits. Anywhere correctness is non-negotiable and the system has to compose hundreds or thousands of rules into an answer you can defend.

Bonus: tax industry experience. Direct work on a tax engine or in tax technology is a strong plus, but not required. What we offer The chance to build on one of the most consequential pieces of IP at Aiwyn, in an industry that's about to change permanently. A direct, reflective leadership team that actively welcomes challenge and debate. Real autonomy and ownership over the systems you build. Competitive

compensation and meaningful equity. Interview process We'll share a detailed interview plan with you on the intro call. The loop is designed to mirror the actual job: real artifacts to react to, conversations that look like the conversations you'd have on

the team, and reference checks taken seriously. We'll move quickly when there's mutual fit.
