Full Stack Developer (m/f/d) - SAP LeanIX

SAP LeanIX is like a living map for enterprise IT: it shows every software application a company uses, who owns it, and how it connects to other systems. That’s why we’re building the SAP LeanIX Store: a place where customers and partners can create, share, and install add-ons to tailor SAP LeanIX to their unique needs.

The Role

As a Full Stack Developer, you will work on both the frontend, built with Angular.js, and the backend, built with TypeScript and Express.js. Your role will be to develop the platform and design how extensions are installed, updated, and retrieved from customer workspaces — with a strong focus on reliability and security. You will also contribute to service stability, working with tools such as error monitoring (Sentry), CI/CD (GitHub Actions, ArgoCD), and observability (Grafana).

You’ll be part of the team building this platform from the ground up — helping define how it works, how it grows, and how it delivers value to users

What you bring

• Strong knowledge of JavaScript/TypeScript and a solid grasp of CS fundamentals, including:
• Data structures (arrays, maps, sets, trees)
• Algorithmic complexity (Big-O)
• Problem-solving and evaluating trade-offs
• Able to analyze problems, compare multiple solutions, and explain reasoning clearly.
• Comfortable working with relational databases — able to:
• Write and optimize SQL queries
• Understand indexes, transactions, schema design, and table relationships
• Experienced with RESTful API development and the HTTP protocol — knows when and how to use different methods, status codes, and headers.
• Has experience with at least one modern frontend framework (e.g. Angular, React, Vue) and is willing to learn Angular.js. Familiar with:
• Component-based decomposition
• State/store management
• MVP or similar UI architecture patterns
• Takes ownership of scoped tasks — understands the goal, collaborates when needed, and delivers solutions that are review-ready, well-tested, and consider edge cases

Bonus If You Have

• Experience with Angular.js and RxJS, especially in SSR contexts
• Familiarity with our stack:
• Node.js + Express.js (backend)
• GraphQL (API)
• PostgreSQL (RDBMS)
• SCSS (styling)
• CI/CD with GitHub Actions and ArgoCD
• Azure (cloud infrastructure)
• Sentry (error monitoring)
• Experience working in structured product teams, collaborating with PMs, designers, and analysts
• Exposure to observability, rollouts, or data-informed development workflow
