AI-first Fullstack Software Engineer (in-person 5x a week)

The first 90 days

• Week 1–2: Ship a real fix to production. Get deep on the codebase and the AI pipelines.
• By day 30: Own a slice of one product/project. Take an MVP feature from "works in the demo" to "works for every firm" — tests, edge cases, error states.
• By day 60: Lead the production-hardening of a roadmap feature end-to-end, and measurably improve the reliability of one AI extraction or review flow.
• By day 90: Own a product surface, ship meaningful improvements every week, and move a number that matters.

Who thrives here

• Backend strength is non-negotiable. Data modeling, APIs, reliability, performance. Ruby on Rails is a plus, not a requirement — we care that you can build a solid backend, not which framework you've used.
• Product and UX judgment is non-negotiable. You feel it when a flow is clunky and you fix it without being asked. React / React Native experience is a plus; UX sense is the actual requirement.
• You're AI-native. You already build with AI tools every day. You know the best practices of AI-first development — when to let the model draft and when to take the wheel, and you never ship confident-sounding slop. AI-generated code gets tested and guardrailed, always.
• Low ego, team-first. You want the team to win. You'll happily spend a day hunting a bug because shipping something solid matters more than your line count. No heroes, no territory.
• Fast and careful at the same time. You move quickly against a clear roadmap and still build it properly. Both, not one.
• You're a builder. You've shipped things — ideally things that weren't assigned to you. Side projects with real users, a product you launched, a startup you started, substantial open-source work, indie-hacking revenue. If you build because you can't help it, you'll fit right in.

Bonus points

• You've built tax, accounting, or other financial software.
• You've worked directly with a founder before.
• You've started or shipped your own product — and you can show it.

A note on fit

We're looking for people who are running toward what we need — not just looking for the next role. The engineers who do their best work here chose Soraban deliberately: they want the pace, the ownership, the AI-first way we build, they love the intensity and hard work culture. If that's you, we should talk. We’re currently receiving 100s of applications so help us identify you, tell us why you standout for this position.

How to apply

• Skip the cover letter. Send links to what you've built — products, repos, case studies, demos. Show us, don't tell us.
• We're an onsite team in Tempe, AZ and San Francisco, CA, and we're excited about our new office. This role is in person.
• You must be legally authorized to work in the US. We're not able to offer visa sponsorship at this time.
• Principals only — no recruiters, please.

A meeting lands on your calendar

If they’re a yes, I book the chat. You show up — that’s the whole job-hunt.
