Engineering
Agent runtimes & developer tooling
Context systems, tool execution, terminals, Git/worktrees, browser automation, recovery, telemetry and desktop application infrastructure.
Careers
Small team.
Hard engineering problems.
Trebell is a five-person early-stage team working on coding-agent infrastructure. We do not currently publish formal full-time openings, but this page is where future roles will be listed.
Product
Developer experience & research
Understanding where coding agents fail, turning that into product requirements, and testing whether harness changes actually improve finished engineering outcomes.
Operations
Early-stage company building
Partnerships, startup programs, growth experiments, infrastructure operations and the unglamorous work that keeps a small startup moving.
No formal openings are listed right now.
If your background is unusually relevant to agent infrastructure or developer tools, you can still introduce yourself at [email protected]. We won't pretend an informal conversation is an advertised job opening.
