Senior Software Engineer API (f/m/d) - Node.js, SQL

AI makes us faster. It doesn’t replace our human judgment. We challenge AI output, verify the results and own what we ship. We experiment fast, learn quickly and deliver with care.

Your Mission

We are looking for a backend specialist who loves the intersection of stability and scalability. Your focus will not be on a title, but on the impact of your code. You will:

- Bridge Systems: Build and maintain robust microservices that ensure seamless communication between internal and external environments.
- Drive Implementation: Take full ownership of features from a raw idea to a production-ready deployment.
- Evolve the Architecture: Contribute to our technical roadmap by questioning the status quo and proposing scalable solutions.
- Secure the Flow: Implement and refine authentication and authorisation flows (OAuth, Auth0) to keep our systems safe and accessible.
- Optimise the Core: Ensure our data layer is lean and fast, applying deep knowledge of SQL and PostgreSQL to solve complex data challenges.

Requirements

Node.js & TypeScript Mastery: You can write clean, maintainable, and type-safe code that thrives in a production environment.; Data Architect Mindset: You don't just write queries, you understand how to design efficient database schemas and optimise them for performance (PostgreSQL).; The Art of Persistence: You know how to leverage ORMs effectively, understanding exactly when they help and when they get in the way.; Quality Obsession: Automated testing (jest/mocha) isn't a chore for you—it's the only way to ship with confidence.; DevOps Basics: You are comfortable with Docker, Git, and the general flow of modern CI/CD pipelines.

Nice to have

Experience navigating the AWS ecosystem or monitoring tools like Grafana, Prometheus, or Graylog.; A track record of mentoring peers or leading the technical direction of a project.; A degree in Computer Science or a self-taught journey evidenced by a strong portfolio.
