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

Description

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

• Your Skills
• 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.
• Bonus Skills (The Power-Ups):
• 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.
• Additional Information
• What to expect at smartclip
• Remote-first, with meaningful time together: We work remotely most of the time, with occasional workshops, team sessions and opportunities to collaborate in person at our tech office in Berlin . We also host team events throughout the year, including our annual Company Offsite, which takes place at a different venue in Germany each year. Being willing to travel to and attend these gatherings is part of the role.
• Ownership over micromanagement: Take ownership of your work and drive your topics forward independently.
• Build > Talk: Try things early, get things wrong early, learn early.
• High standards, low ego: We give direct feedback and work together openly and respectfully.
• Keep growing: Develop your skills through hackathons, conferences and community exchange.
• And of course, the benefits matter, too: 30 days of annual leave, plus December 24 and 31 off, Smart Fridays with the option of a four-day workweek, a Deutschlandticket (public transport pass) and JobRad bike leasing, sports and health benefits, mental health support, corporate discounts, access to RTL+ and much more.
• Your CV is just the beginning.
• What interests us more than your CV is a portfolio, a side project or a demo repo – something that shows us how you approach technical challenges and turn ideas into working solutions.
• AI disclaimer: AI was allowed to contribute ideas, but it didn’t get the final say. We kept that privilege for ourselves.
• Company Description
• 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.
