Jobbeschreibung

Join DKB Code Factory’s Platform team as a Mid Frontend Developer (React) and help design, build, and evolve the shared web foundations that accelerate delivery for multiple product teams at a major digital bank. In this role you’ll work hands‑on with React and TypeScript to improve build pipelines, shared libraries, CI/CD, and developer workflows — delivering measurable improvements to engineering velocity and reliability while growing your technical craft.

Responsibilities

• Design, implement, and maintain shared frontend foundations, libraries, and tooling that are used across multiple product teams.
• Ship production‑ready platform improvements (build pipeline optimizations, reusable components, local dev tooling, CI/CD automation) with tests and documentation.
• Lead cross‑team initiatives: author RFCs/proposals, coordinate sign‑offs, and drive incremental rollout and adoption.
• Improve developer workflows by reducing build/test friction, stabilizing CI, and improving onboarding and local setup. Measure and report impact.
• Provide technical guidance and code reviews to product teams to prevent duplication and ensure consistency with platform standards.
• Maintain observability for platform health (build/test reliability, performance metrics) and respond to platform incidents collaboratively.

Qualifications

• 3–5 years of relevant frontend or platform engineering experience (Mid level).
• Strong practical experience with React and TypeScript.
• Experience with testing and automation: Playwright, Testing Library, Vitest or similar.
• Experience working with bundlers / module systems (Module Federation, Webpack, Vite) and build tooling.
• Hands‑on familiarity with CI/CD pipelines and release automation (e.g., GitHub, Actions, GitLab CI).
• Comfortable with command‑line tooling, Bash scripting, and YAML configuration.
• Good communicator who can collaborate across teams and write clear technical proposals and documentation.
• Working knowledge of security and accessibility basics required in a regulated banking environment.
• English required; German B1/B2 helpful but not mandatory.
• You're passionate about your work, but also know how to enjoy your free time!
