Requirements
- 4+ years building backend systems, including 2+ years writing Go in production
- Real Postgres depth — schema design, migrations against live data, and knowing why a query got slow
- Have built and operated asynchronous systems: background jobs, queues, retries, and the failure modes that come with them
- Bias toward correctness in a domain where a wrong number has consequences, and the judgment to know when it doesn't
- Comfortable operating in a fast-changing, early-stage environment
- Excellent verbal and written communication skills
Nice To Haves
- Connect RPC, gRPC, or protobuf-first API design
- Event-driven architectures on RabbitMQ, Kafka, or similar
- Infrastructure as code — Pulumi, Terraform, or CDK — and comfort owning your own deploys
- Shipped LLM systems into production paths and evaluated them properly, not as prototypes
- Built tax-adjacent software — fund administration, payroll, accounting platforms, filing systems
- Enjoy getting creative with APIs and systems that were never meant to be automated
Responsibilities
- Own modules in the Go monolith end to end — schema and migrations through Connect RPC surface, including the background jobs and pub-sub flows behind them.
- Automate systems nobody meant to be automated. Our industry never built APIs. We drive a desktop tax platform through a C# agent, parse filings that arrive as scanned paper, and reconcile ledgers that disagree with each other. This is most of the interesting work.
- Put AI on the critical path. Wire ModelBridge into real workflows and hold it to TaxBench, our eval suite — we treat eval as an asset, not a side project. A model that's right 95% of the time is a design problem, not a launch.
- Own what you ship in production. Tracing, alerting, on-call, and the load curve of a firm whose traffic triples in March. April 15th doesn't move.
- Work directly with preparers. The people who'll catch your bug are on Slack, and they'll tell you exactly what happened.
Benefits
- Benefits and meaningful equity
- A fully remote team, plus twice-yearly company offsites
- A well-funded, fast-moving environment with minimal layers of management
- A world-class client base that values your time and pays for the premium experience
- Problems that are unusual — nobody else is writing daemons against 1990s tax software to feed a modern agent stack
