Product Engineer (Backend)

You will build the backend systems that make this company's product reliable, extensible, and safe to use in real legal work. These systems power everything lawyers see and trust: documents, matters, permissions, agent actions, and the workflows that tie them together.

At a high level, they are building a Cursor-like environment for legal work, where lawyers collaborate with agents that can search, reason, and act on documents, while remaining auditable, reversible, and correct. The backend defines what is possible here, and what is safe.

This is a product-first backend engineering role. To succeed, you’ll need to understand the full product surface and agent behavior, so you can design systems that evolve quickly without breaking under real-world usage.

What you’ll build:
- Core product APIs: Design and evolve the APIs that power the lawyer dashboard: matters, documents, chats, permissions, and email integration, so legal work stays coherent across tools, collaborators, and time.
- Data models and pipelines: Define and maintain data structures that support evolving product and agent workflows, including document state, provenance, permissions, and history. You’ll think carefully about boundaries, migrations, and long-term extensibility.
- Agent-facing backend surfaces: Build the primitives that let agents safely operate in the system: scoped permissions, state transitions, execution boundaries, and backend objects that unlock new tools and workflows without sacrificing control.
- Infrastructure and reliability: Own backend systems in production. Contribute to deployments, observability, performance, and cost awareness, while keeping the focus on product reliability rather than infrastructure for its own sake.
