Software Engineer, Frontier Data Products

Frontier AI companies are increasingly bottlenecked on expert judgment and high-quality data workflows. This team builds the production systems that capture, coordinate, and validate that work at scale — directly between a customer request and the output that ships.

Responsibilities

Design services and state models for multi-stage workflows that fan out across automated processing and expert reviewers, then reconcile results into a coherent whole; Build orchestration primitives — retries, failure recovery, idempotency, auditable state transitions — for jobs that run far longer than a request and can be partially redone after the fact; Integrate model inference into production workflows without sacrificing debuggability or human oversight; Build the APIs and tooling that let product, operations, and ML teams operate, debug, and trust these systems at scale; Own reliability and observability for workflows where a silent failure means a corrupted result, not just a 500

Requirements

Production backend experience with strong opinions about what ages well and why; Sharp instincts for system design, service boundaries, and where to put complexity — and where to refuse it; Fluency with the distributed systems toolkit: async workflows, queues, idempotency, retries, and long-running jobs as practice, not resume line items; Ability to take ambiguous product, operational, and ML constraints and turn them into a system that is clean and debuggable; Comfort working in Python on AWS with Postgres; Gets frustrated by systems that are hard to debug and takes that personally enough to fix it; Has strong opinions about where state should live and can defend them in a design review; Moves fast but doesn't treat reliability as someone else's problem; Wants your work to have a short, visible line to outcomes that actually matter to customers

Nice to have

Experience with Temporal or similar workflow engines
