Software Engineer, Payments

- 5+ years of professional software engineering experience , with a track record of taking full ownership of the projects you take on.

- Hands-on technical depth in domains where correctness matters. You've shipped real systems where edge cases, accuracy, and domain depth were non-negotiable.

- Experience with fintech and payments. Direct work on payment systems, money movement, or collections. You understand why getting money movement right is non-negotiable, and you've shipped systems where that showed.

- Demonstrated ability to bridge engineering and a non-engineering domain. Engineers and finance/accounting 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: deeper fintech and/or payments experience. Building or contributing to a payments, billing, ledger, pricing, underwriting, claims adjudication, compliance, or benefits system - anywhere correctness is non-negotiable and the system has to compose hundreds or thousands of rules into an answer you can defend. Payments specifically in the accounting industry is the strongest plus of all, but none of this is required.

- The chance to build on one of the most consequential parts of the Aiwyn platform, 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.

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.
