At the heart of our internal operations and customer interactions are comprehensive, web‑based management solutions. These systems are critical for bridging our internal management workflows with seamless, user‑facing solutions. To build and scale these systems, we are looking for an experienced full‑stack web developer to join our team.

In this role, you will work closely with product and engineering leadership, taking well‑defined product requirements and turning them into robust, high‑performing technical realities. The ideal candidate takes pride in writing clean, modular code, applying strong software design patterns, and executing with a product‑minded approach. You will be a key engineering partner, helping build the digital infrastructure that supports the future of satellite deployment.

Your role is based at our HQ office at Potsdamer Platz.

Your mission

• Take well‑defined product requirements and turn them into robust, high‑performing technical solutions across the entire stack.
• Design, build, and scale maintainable features, ensuring high performance, security, and reliability.
• Apply strong software design patterns and best practices to solve complex business logic, keeping the codebase modular and scalable.
• Work collaboratively with the Product Manager to understand the "why" behind features, remaining mindful of the overall product vision and end‑user experience during implementation.
• Securely integrate Identity and Access Management (IAM) solutions, manage database interactions, and maintain CI/CD pipelines.
• Foster a collaborative technical environment through thorough code reviews, knowledge sharing, and upholding high technical standards.

Your profile

• Strong experience building performant, scalable web applications with a deep understanding of software design patterns.
• Deep understanding of data flow across distributed systems, including client‑server communication paradigms, state management, asynchronous processing, and secure API boundaries between decoupled frontend and backend services.
• Backend: Mastery of modern, strongly‑typed or functional programming. Experience with Rust (Axum/Tokio) is a big plus. Experience in Python is also a plus.
• Frontend: Strong TypeScript experience with modern frameworks, preferably Next.js/React or SvelteKit/Svelte 5 with the agility to master the counterpiece quickly.
• IAM & Security: Hands‑on experience with OIDC/OAuth2 protocols, integrating IAM setups (e.g., Keycloak, FusionAuth, Auth0, Okta) and securing APIs. Familiarity with Auth.js (NextAuth/SvelteKitAuth) is a plus.
• Infrastructure & Data: Strong experience with PostgreSQL and familiarity with NoSQL databases. Experience with multi‑model or graph databases (e.g. SurrealDB) or Redis is highly valued. Proficient with Docker‑based deployment and development.
• CI/CD: Proficient with GitHub Actions, Git‑based workflows, and writing comprehensive automated tests.
• Excellent written and spoken English, with strong technical communication skills.
• Positive, proactive self‑starter attitude with the ability to work in a highly integrated team setting.
