Software Engineer (Remote)

About the role

You'll build the AI systems top PE funds run live deals on. Ingestion that structures chaotic data rooms. Agents that run deterministic analysis on top. Review surfaces that make model output trustworthy enough for an investment committee. Evals, retrieval, tool use, orchestration — held to the bar of a real deal clock.

Responsibilities

• Deepen the agent layer. We view the agent as a first class citizen. Not a demo. This means harnesses, planning, subagents, compaction, tool-use design — the primitives that decide whether the system scales with complexity or collapses under it. This will require iteration, decisiveness, and staying abreast on frontier updates.
• Own the deterministic core. Our computation and fact gathering allows any consumer to pull any intermediate artifact from a deal, compose real analytical logic on top, and return a number an IC would defend.
• Build evals that actually catch regressions before customers do. Not vibes. Real test harnesses for agent output, extraction accuracy, and analysis correctness.
• Harden the ingestion layer so it handles data rooms with unknown schemas, malformed files, and edge cases that only show up in real deals.
• Own the infrastructure that keeps the platform fast under real load. Concurrency, queueing, caching, cost — the systems work that decides whether we can run ten deals in parallel or ten thousand.

Requirements

• You think in systems and ship in days. You know when to build the abstraction and when to skip it.
• You've succeeded at something hard and can point to it. A company you started. A team you led. A product people used. A bar you cleared that most didn't.
• You've built and operated production systems that broke, and you fixed them. Not prototypes. Not side projects. Real consequences.
• Broad across the stack. No layer is someone else's problem.
• Languages/tools: Python/React shop. We care less about stack fluency than systems instincts across the stack.
• Obsessive about testing. E2E, integration, browser — you don't ship without them, and you don't trust anyone who does.
• A point of view on the current agent landscape, and a sense of what's real vs. demo-ware.
