Zusammenfassung

DCS is seeking a Staff-level software engineer to lead the design and implementation of major platform changes. You will set the technical bar for the team, promoting AI-assisted engineering and serving as a multiplier for colleagues across projects.

You will champion distributed systems, CQRS, and event-sourcing, while guiding data modeling and API gateway patterns. Fluent English is expected; German would be a plus.

Qualifikationen

• Eight-plus years of professional software engineering at staff level with cross-team impact.
• Strong polyglot background centered on JVM; Go/Node.js welcome.
• Production-grade experience with event-focused systems; Kafka required; Flink a plus.
• Deep understanding of idempotency, exactly-once vs at-least-once, backpressure, schema evolution, partitioning.
• Experience designing/operating CQRS and event-sourcing; know when not to use them.
• Hands-on with API gateway technologies and patterns (routing, rate limiting, auth).
• Strong DB judgment across relational (PostgreSQL) and non-relational stores; data modeling under load.
• Proven track record steering multi-team technical projects end-to-end.
• Daily use of AI coding tools (Claude Code); familiarity with Codex/open-source tools.

Aufgaben

• Lead design and implementation of platform-wide changes.
• Set technical bar and drive AI-assisted engineering practices across the team.
• Sponsor design reviews, surface real tradeoffs, and align stakeholders.
• Mentor engineers, raise engineering standards, and spread technical authority.
• Apply distributed systems patterns with sound judgment and simplicity where appropriate.

Jobbeschreibung

Make an Impact by:

You will spearhead the design and implementation of significant platform changes. You will set the technical bar for the team, raise the bar on how AI-assisted engineering is done at DCS, and act as a team multiplier for everyone around you. We organize expectations into Primary and Supporting areas.

• You author or sponsor design documents that achieve stakeholder alignment without escalation. You run design reviews that surface real tradeoffs, not rubber stamps. Your input on the technical roadmap is visible, justified, and acted on.
• You raise team engineering standards through direct contribution and peer influence. You earn technical authority through reasoning quality and output.
• You use AI tools as a serious engineering accelerator and you build the same capability in others.
• You apply distributed systems patterns (event-focused, CQRS, API gateway, event sourcing) with demonstrated judgment about fit.
• Written and verbal communication. You produce written artifacts (design docs, proposals, postmortems) that are clear, structured, and direct to alignment without repeated clarification rounds.
• Technical pattern judgment. You know when not to use a pattern. The Staff level requires the confidence to advocate for simplicity against organizational momentum toward complexity.
• Database and data model judgment. You apply sound judgment to data modelling, query performance, and schema migrations under load. You identify performance and migration risks before they reach production.
• Code and review quality. Your code contributions are production-ready: correct, observable, operable, maintainable. Your code reviews are substantive. You identify real risks and design issues, not style preferences.

Your Profile

• 8 years of professional software engineering experience, with clear evidence of operating at a Staff level (cross-team technical impact, ownership of significant platform-level work, mentorship of senior engineers)
• Strong polyglot foundation. Primary stack is JVM (Java and Kotlin); experience with Go or Node.js is welcome
• Deep, production-grade experience with event-focused systems. Concrete experience with Kafka is required; Flink (or comparable stream processing) is a strong plus
• Solid command of distributed systems fundamentals: idempotency, exactly-once vs at-least-once tradeoffs, backpressure, schema evolution, partitioning
• Experience designing and operating CQRS and event-sourcing patterns, and the judgment to know when not to use them
• Hands‑on experience with API gateway technologies and patterns (routing, rate limiting, auth, traffic shaping)
• Strong database judgment across relational (PostgreSQL) and non‑relational stores, including data modelling, query performance, and migrations under load
• Proven track record of steering complex, multi‑team technical projects end‑to‑end
• Effective use of AI coding tools as part of your daily workflow. We use Claude Code.
• Experience with similar tools (OpenAI Codex, opencode, Cursor and others) is fully transferable, but we want to see real fluency, not surface‑level use
• Familiarity with cloud service providers, ideally Azure
• Comfortable with container technologies (Docker, Kubernetes)
• Fluency in English; German is a plus

We Offer:

• A unique opportunity combining the energy of a scale up with the power of BMW, Mercedes Benz Mobility & bp
• Working on products & services with a high social impact
• An international team of talented people who love what they do and live a collaborative spirit
• An open minded culture with room for growth and the freedom to bring in own ideas
• Subsidized gym membership
• Subsidized office lunch benefit
• Personal development budget for your professional growth
• Monthly mobility budget
• Up to 2 days of home office in a week
• Offsite/ team events & much more and modern, sunny offices in Berlin & Munich

... and of course the classics: delicious coffee & tea, fresh fruits and an office dog friendly environment
