- Experience building and operating cloud-native, production-grade distributed systems;

- Comfortable owning system design and shipping to production without support, including on squads running solo with no ramp-up runway;

- Has concretely built a shadow-test/dual-write migration path or a reversible-operations model for destructive actions before — not just read about the patterns;
- Backend-leaning specifically, to correct the program's existing front-end skew;

- Prior experience leading a team or owning technical direction solo is a strong plus, given the possibility of squad leadership.

Technology Stack:

- Python(FastAPI, SQLAlchemy), Typescript(React), PostgreSQL, Redis, Pinecone DB.

Responsibilities:

- End-to-end ownership of complex, production-facing features with a backend-leaning skillset — data models, APIs, and the infrastructure they run on, not just UI;
- Safe migration patterns for legacy or high-risk systems — e.g., shadow-testing/dual-write layers that validate new logic against live production traffic before cutover, rather than big-bang rewrites;
- Reversibility by construction for destructive or bulk operations — undoable-command or versioned-transaction models with a true inverse operation, not a confirm-dialogue bolted on after the fact;
- Setting technical direction and raising the bar for code quality on a squad, including in situations with no peer to check your judgment against;
- Potential to lead a squad directly, including standing up intake/triage/routing from zero and taking on forward-deployed customer-facing duties.

We offer:

- Variety of domains;

- Full stack of technologies;

- Professional and highly interactive team environment;

- Management style based on openness and trust;

- Stable support in personal education and growth;

- Worthy compensation;

- Active community with regular knowledge sharing;

- Flexible work conditions.
