Requirements
- 5+ years building software at a product company, with ownership of meaningful parts of a real production system.
- Strong Java skills including REST APIs, database interactions, and async processing.
- Expertise in TypeScript and a modern frontend framework (Angular preferred).
- Frontend fundamentals: complex UIs, component architecture, state management, performance, and responsive design.
- Solid SQL experience in a backend context (schema design, query optimization, migrations).
- Experience with production databases like MySQL and ClickHouse.
- Testing as a habit: writing unit, integration, and e2e tests (Cypress/Playwright).
- Architectural judgment: designing APIs and understanding data flow and latency.
- DevOps fluency: containers, CI/CD, infrastructure-as-code, and Linux proficiency.
- Agentic engineering: ability to ship production code using AI coding agents (e.g., Claude Code, Cursor).
- Independence in a distributed, async team.
- Fluent English.
Responsibilities
- Build features end-to-end: backend APIs, database changes, frontend UI, and ship them to production yourself.
- Design and implement backend services for a multi-tenant SaaS platform.
- Work with relational databases (MySQL): schema design, query optimization, data modeling.
- Build frontend features that are clean, fast, and don't get in the way.
- Optimize performance across the stack and write tests at every layer (unit, integration, e2e).
- Build agentic features into the product: LLM-powered workflows that help users find, understand, and fix data issues.
- Improve our systems for agentic development: agent instructions, skills, and the test feedback loops.
- Work directly with product, design, and customers to decide what to build.
