Jobbeschreibung

• We are modernising and consolidating our services in the cloud, and we are building the internal platform that lets product teams ship and run those services with confidence
• This role builds that platform. It also stays close to the code, in the same cloud-native, TypeScript and Node stack the product teams use
• This is a hands‑on individual‑contributor role on the Platform team. You will design, build and ship, and you will work directly with product engineers to help them solve their infrastructure problems
• Build and operate the internal developer platform, the paved road of tooling and infrastructure that lets teams set up and run their own services without waiting on us
• Drive our cloud migration, moving and consolidating services into a modern cloud‑native setup without slowing delivery
• Design system and infrastructure architecture and communicate it clearly, including diagrams that other engineers can build from
• Work alongside product engineers and get them unblocked, because the platform exists to serve the product
• Deliver with coding agents as a matter of course, and help improve how the whole team does so
• Experience with monorepo build systems and shared tooling
• Previous cloud‑migration work
• A track record of building internal command‑line tools or code generators
• Public technical work, such as open-source contributions or writing

Benefits

• 30 vacation days and flexible working hours
• BVG card or Swapfiets bike
• Jobbatical and Sabbatical options
• Many internal & external learning opportunities to choose from
• A yearly Learning & Development budget
• Visa and relocation assistance
• Full access to Babbel & Babbel Live classes
• Modern office in the heart of buzzing Berlin equipped with a family, music, faith and nap room
• Various internal communities to be part of including the Femgineers, DEI Ambassadors, Accessibility & Disability Group and more

A track record of building or choosing internal tooling that lets other engineers work faster, with the judgement to adopt an existing solution when one fits rather than build from scratchStrong, hands‑on cloud engineering experience on AWS at organisational scale: multi‑account setups, identity and access, networking, and account‑level guardrails. Serverless is our default but we want someone who can pick the right tool for each problemCoding agents are part of your daily workflow, and you check their output before you rely on it. You are neither dismissive of them nor careless with themTypeScript on Node.js as your primary application language, or a deliberate and recent move to it. Python is a welcome secondary. Go or Rust are useful for performance‑critical componentsA security‑first instinct: least privilege, secrets management, and treating patching and vulnerability remediation as routine workDeep, hands‑on experience with infrastructure as code. You have built and maintained real production estates in Terraform, or a close equivalent, and you are comfortable owning delivery pipelines on AWSDelivery experience in both lean startup settings and larger organisations, with ownership from start to finish. You scope a sensible first version and build on itWe are a learning company, inside and out, and we encourage you to apply even if you do not fit all the technical requirements — all candidates are assessed based on skills, qualifications, and our business needsPublic technical work, such as open‑source contributions or writingA track record of building internal command‑line tools or code generatorsPrevious cloud‑migration workExperience with monorepo build systems and shared tooling
