Software Engineer (Staff)

The engineer who can't operate AI agents fluently is becoming obsolete, fast. Fluency with Claude, Cursor, and internal agent tooling is a second cortex.

"Backend vs. frontend" is dissolving. The agents do the typing. The constraint is product judgment, system design, and the ability to close the loop from problem to shipped feature. Staff engineers ship full-stack when the work calls for it.

The pod is the unit of leverage. Two engineers who can hold an entire module in their heads ship more than ten engineers who each own a slice. Specialization across pods, generalist within them. Staff engineers raise the ceiling for every pod.

The accountant + engineer loop is the moat. Engineers who sit with controllers and build from what they see compound faster than the ones who don't.

You can learn an accounting workflow in an hour and have it in code by the end of the day. A controller walks you through a prepaid amortization across 80 entities; you spot the edge cases she didn't think to mention. The single most important skill on the team.

You're a current or future founder. You scope your own work, think about the customer, own your decisions.

You solve problems end to end. The team is split vertically, so every engineer owns a part of the product and makes decisions across the LLM pipeline, infrastructure, backend, and UX.

You care about getting it right. A 100% solution beats an 80% one. When something breaks, you go to root cause.

You don't graduate out of code. You write the trickiest reconciliation logic yourself.

8+ years of software engineering with deep specialization in distributed systems, ledger / transactional systems, data infrastructure, integration platforms, or AI/agent platforms.

Strong backend chops in a modern language — Python, Go, Java, Rust, or similar. Our stack is Python; if your deep experience is elsewhere, ramp fast. Ships TypeScript when needed.

Built load-bearing systems multiple teams depended on, and made architectural calls that compounded for years.

Worked at an early-stage startup (pre-seed through Series B).

Prior Staff or Principal IC experience at a high-growth startup.

You've worked at an accounting, fintech, or ERP-adjacent SaaS startup, or built ledger / sub-ledger systems.

You've designed and operated AI agent platforms in production — evals, guardrails, observability, orchestration.

You've operated systems under audit or regulatory scrutiny — SOX, SOC 1/2, financial audit. You understand why "right" matters more than "fast" on certain code paths.

Exceptional teammates — unusually smart, unusually driven.

Join a rocketship. Revenue has grown more than 10x in six months.

Top-of-market compensation benchmarked to top NYC startups.

Meaningful early-stage equity in a company already shipping to enterprise customers.

Full medical, dental, and vision; 401(k) with match; flexible PTO; paid sick leave.

Corporate card for meals, stocked office, commuter benefits.

In-person, NYC. Not remote. The work compounds when we're in the room.
