Engineering surface
Real product work, scoped to your level.
You'll work across the stack — Go services, PostgreSQL flows, React surfaces — on features that ship. Code review is direct, the projects are well-scoped, and you'll see your work in production.
01
Go services and APIs
Work on the API layer, background workers, and service internals that keep the control plane running.
02
PostgreSQL and data
Write migrations, queries, and data flows. Learn event sourcing, read models, and tenant-scoped storage patterns.
03
React product surfaces
Build and refine the operator-facing UI: workspace dashboards, agent configuration, usage views, and approval flows.
04
Agent runtime
Help improve sandbox execution, checkpoint recovery, prompt packaging, and retry behavior for running agents.
05
Testing and reliability
Write unit tests, integration tests, and end-to-end coverage. Help make the system provably correct.
06
Developer tooling
Improve local development, CI pipelines, deployment scripts, and the tools the team uses every day.
Open role
Engineering Intern
**Responsibilities**
* Ship real features and fixes that reach production, not toy projects or busywork.
* Work across the stack: Go backend, PostgreSQL database, and React frontend as needed.
* Write tests that match the risk level of the code you are changing.
* Participate in code review and learn from direct feedback on your work.
* Help improve developer tooling, documentation, and local development workflows.
* Take ownership of well-scoped projects and see them through to completion.
You might be a fit if
* You build things on your own time. Side projects, open source, class projects that went beyond the assignment.
* You are comfortable reading and writing code in at least one of Go, TypeScript, or Python.
* You have used a relational database and understand basic SQL, schemas, and migrations.
* You are curious about distributed systems, event-driven architecture, or infrastructure.
* You prefer learning by doing over learning by watching.
* You care about the details. Clean code, clear naming, consistent formatting.
