About The Position

Aiwyn is the first complete platform for modern Accounting Firms. We are a fast-growing scale-up SaaS company building category-defining technology. We are hiring a senior software engineer to join the team that owns our accounting practice management platform, which is the system of record for how firms track work, bill for it, and collect payments. Our accounting practice management platform is one of the most strategic pieces of the Aiwyn platform, where the work firms do turns into revenue tracked, billed, and collected. This platform is the foundation for firms to manage the full lifecycle: project and time tracking, resource management, billing, invoicing, and accounts receivable, ensuring all work is tracked, billed, and accounted for.

Requirements

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.
Demonstrated ability to bridge engineering and a non-engineering domain. 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.
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.

Nice To Haves

Experience in project management and/or fintech software.
Experience building or contributing to a billing, ledger, workflow, role based access control (RBAC), authentication, or comparable system.
Experience in Practice management, billing, pricing, underwriting, claims adjudication, compliance, benefits.

Responsibilities

Build the systems firms run their business on.
Own the services, infrastructure, and confidence metrics that let practice management grow at speed without sacrificing accuracy or trust.
Make the iteration loop faster every cycle.
Work in the trenches with domain experts to understand how accounting firms run and translate that depth into the systems you build.
Build and extend the APIs that Aiwyn, firms, and partners build on top of.
Take projects from spec to ship to scale, owning the work end to end, including parts outside your comfort zone.
