Software Engineer

CI HUB - Software Engineer (Full Stack / Backend) – Hybrid (Frankfurt/Gießen Area)

Backend-heavy full-stack role. Real ownership. Real product impact.

This is a full-time, remote-first role with regular in-person collaboration around Frankfurt / Gießen. We’re primarily looking for senior candidates, but strong mid-level candidates can still be a good fit. English is our working language. German is a plus, but not required.

Small team, real ownership.Build it, run it, maintain it. We work in English, manage our own time, and give direct feedback.Test-driven development is the default. We look for people who think beyond tickets and shape how things are built. Flexible hours. Incidents are rare.

Position Overview: This is a backend-heavy full-stack role focused on building our new platform — including billing, authentication, user management, licensing, as well as APIs and data-related work. Our stack includes Node.js, PostgreSQL, REST, Docker, Redis, and queues, with Vue on the frontend where needed. English is our working language. Test-driven development is the default for new behavior, and you’ll have real ownership of what you build. We work remote-first, with regular in-person collaboration around Frankfurt or Gießen on a flexible cadence. We’re primarily looking for senior candidates, but strong mid-level candidates can also be a good fit.

About CI HUB: We provide simple access to 60+ DAM systems in tools where work actually happens (MS Office, Google, Adobe Apps, Canva, Figma, AI and more). We're 50 strong, profitable, growing, and sitting on a massive market opportunity. The Role You'll own the products that determine how customers discover, adopt, and expand their use of CI HUB: sign-up and upgrade flows, license management (My CI HUB), payment, and one used by thousands of creatives: Connector Professional. Some need optimization, some need rethinking, all of them sit at the intersection of user experience, business model, and platform strategy. Your decisions move revenue & adoption metrics.

What You'll Do:

• Design, build, and maintain backend services and REST APIs, including data access and integrations, using Node.js, PostgreSQL, and supporting tools such as Docker, Redis, and queues

• Contribute to full-stack development when needed, using Vue on the frontend (the role remains backend-led)

• Follow test-driven development (TDD) as the default for new functionality: small iterations, meaningful tests, GitHub pull requests, and continuous integration

• Work on platform-level topics such as billing, authentication, user management, licensing, and related product features

• Take ownership of complex integrations (OAuth, webhooks, retries, idempotency) and ensure reliable behavior when external systems change

• Apply solid system design principles, including trade-offs, failure scenarios, and production readiness

• Participate in code reviews and technical discussions, supporting team growth through collaboration and feedback

• Collaborate using tools such as Asana (or similar), Slack, and internal documentation (Slab) What We're Looking For:

• Strong experience with Node.js and JavaScript or TypeScript

• Solid SQL skills and hands-on experience with PostgreSQL in production

• Experience designing and consuming REST APIs

• Familiarity with Git and a standard GitHub pull request workflow

• Experience with Docker in a development setup aligned with production

• Practical experience with Redis and message queues

• Understanding of server-side concurrency (event loops, background jobs, etc.)

• Basic frontend experience with Vue (enough to contribute when needed; this is not a frontend-first role)

• Professional working proficiency in English (spoken and written) Preferred qualification :

• Experience in B2B SaaS, subscriptions/billing, identity & authentication, or licensing

• Strong TypeScript skills beyond basic usage

• Familiarity with OpenAPI or similar approaches to API contracts

• Experience with CI/CD pipelines and automated testing

• Experience using tools like Postman for API work

• Professional working proficiency in German What You Get:

• Competitive salary, flexible hours, fully remote. Learning budget.

• Modern hardware & software.

• 1-2 team get-togethers a year at fun destinations.

• Ownership over products that directly shape how thousands of users experience CI HUB.

• Uncomplicated, supportive leadership, no politics, real impact. And a role where you can prove that a sharp PM with the right tools can do the work of three
