[Hiring] Full-Stack Engineering Intern @Rivet

Role Description

We don't run an internship program. There's no cohort, no intern project graveyard, no summer showcase. We open this role when we meet someone we're excited to work with, and the work is the same work everyone else is doing.

• You'll ship to production.
• Ownership from first commit to production.
• Decisions happen at the edge.
• Clear is kind.
• We're hiring you for slope, not credentials.

Our stack:

• Platform: Go, as a modular monolith — Connect RPC over protobuf, Go Fx for wiring, sqlc and goose against Postgres, River Pro for background jobs, Watermill for pub-sub over RabbitMQ.
• Frontend: React and TanStack, deployed to Cloudflare Workers.
• AI and eval: Python, in their own repos — ModelBridge (a gRPC service for AI building blocks) and TaxBench, our internal eval suite.
• Legacy integration: a C# Windows agent that drives Drake, one of the tax platforms our industry never built APIs for.
• Infrastructure: AWS — ECS Fargate, Amazon MQ, AMP, Loki, Tempo — provisioned by Pulumi, itself written in Go.
• Around the edges: Buildkite for CI, OpenTelemetry throughout, Doppler for secrets, Linear for tracking.

What you'll do:

• Own a scoped feature end to end — Postgres schema, Go service, protobuf contract, React screen.
• Pair with the engineer who owns that module.
• Work on the automation problems.
• Talk to accountants every day.
• Ask questions in public.

Qualifications

• You've built things outside of coursework — side projects, open source, a company, something you shipped because you wanted it to exist.
• Working knowledge of at least one of Go or React, and real interest in the other.
• You can read unfamiliar code and make progress without a tutorial.
• You write clearly. Remote and asynchronous means most of the job is writing.
• You want feedback and do something with it.
• Enrolled in or recently out of a degree program, or self-taught and at an equivalent point.

Requirements

• Nice to haves:
• Postgres beyond an ORM.
• Any exposure to protobuf, gRPC, or typed API clients.
• You've used LLMs to build something real, and have opinions about where they fail.
• Curiosity about tax, accounting, or other domains where a wrong number has consequences.

Benefits

• Paid.
• A named mentor, a real project, and a direct line to the CEO.
• A fully remote team, plus twice-yearly company offsites.
• A well-funded, fast-moving environment with minimal layers of management.
• An honest conversation about a full-time offer at the end, in either direction.
• We open this role rarely and only for people we're excited to mentor.
