We’re looking for two highly skilled backend engineers to help lead a full backend refresh and rewrite effort. The team recently completed a major front-end migration to Svelte and is now focused on modernizing the backend for scale, reliability, and long-term maintainability.

What You’ll Do

Lead backend development using Java and Spring Boot to refactor and rebuild existing services and modules.

Work hands‑down on performance optimization — threading, async processing, scaling servers, and improving overall architecture.

Build and maintain automated unit, integration, and end‑to‑end testing frameworks.

Collaborate closely on site reliability, uptime, and debugging critical issues such as memory leaks and performance bottlenecks.

Help shape technical direction for the final iteration of the product as the company moves toward a potential exit.

Contribute to decisions on refactoring strategy, infrastructure improvements, and architectural planning.

What We’re Looking For

Deep experience with Java performance tuning, Spring Boot async tasks, and distributed server infrastructure.

Strong background in automated testing (unit/integration/e2e).

Experience improving system reliability, uptime, and debugging complex production issues.

Hands‑on experience refactoring or rewriting large, complex backends.

Ability to execute independently while communicating clearly and contributing to architectural decisions.

Bonus: experience with large‑scale codebase modernization, module‑based refactoring, or migrations from Hibernate to jOOQ.
