Must-have expectations - Strong autonomy on a Django (Python) stack (no planned upskilling on these fundamental) - Testing discipline (useful tests, reproducibility) and systems thinking (performance / reliability / security impact) - Mission-first mindset: willingness to “cross the aisle” and contribute where the mission needs it - Ability to operate in a demanding environment (quality, security, ownership) ## Responsibilities - Own a topic end-to-end (technical scoping, implementation, tests, documentation, delivery) - Participate in the team’s development cycle: PRs, code reviews, feedback loops, iterations - Maintain production-grade quality (robustness, security, readability) - Communicate clearly on progress, risks, and trade-offs Project section (examples of contractor-friendly topics) These are examples (non-exhaustive) and may evolve: - Database split to enable a future single-tenant deployment (migration / progressive separation) - GitLab integration (existing spec) - Prompt management migration (from client to backend) - Security backlog (bug bounty-related issues) Contractors are expected to be fully part of the team’s development flow (reviews like everyone else). Core vision / research topics will typically be handled by full-time engineers.
