(Senior) Software Engineer - Enpal Energy (f / m / x)

Stellenbeschreibung

Take end-to-end ownership of building and scaling backend features, services, and systems (NestJS / Node.js).

Design and deliver reliable, secure, and scalable backend services; occasionally support lightweight frontend tasks when needed.

Build, design, and integrate REST APIs with internal and external systems; collaborate closely with cross-functional engineering teams.

Own deployments, build and maintain CI / CD pipelines, manage infrastructure as code, and ensure smooth production operations.

Write clean, testable, and maintainable code with a strong focus on long‑term quality and scalability.

Monitor systems, troubleshoot complex issues, drive performance improvements, and contribute to architectural decisions.

(For senior‑level candidates) Mentor and guide other engineers, drive technical discussions, and help shape engineering best practices.

Qualifikationen

4–6+ years of professional software development experience (mid‑level to senior).

Strong proficiency in TypeScript and Node.js, or deep experience in other modern backend languages with willingness to adopt our stack.

Hands‑on experience with backend development; some exposure to React / Next.js is a plus but not required.

Strong experience working with MongoDB or other NoSQL databases, including schema design and optimization.

Proven track record building and consuming APIs; experience with cross‑team integrations.

Experience owning backend projects end‑to‑end—from concept to deployment and maintenance.

Solid experience with CI / CD tooling (GitHub Actions, Azure DevOps, or similar).

Strong commitment to code quality, testing best practices, and building systems that scale.

(For senior‑level candidates) Experience mentoring others, leading technical decisions, or setting engineering standards.
