Principal Engineer (f/x/m)

Requirements

• A deeply experienced, hands-on technologist, typically with 8+ years building production software, able to own systems design and still ship code others learn from.
• Fluent in German and English, both essential for our engagement with German banks.
• Large-enterprise context: you have delivered systems inside a large corporate or for a vendor supplying one, and understand how enterprise architecture reviews, security assessments, and change control work.
• Excellent systems design skills, covering distributed systems, services, contracts, data, and integrations.
• AI-forward: you already use coding agents and AI-assisted building in your own work or personal projects.
• A track record of raising the engineers around you through influence, design review, and example.
• Senior-management maturity: you translate technical risk into terms the business can act on.
• Credible and calm when bank architects and risk functions question design choices.
• Security-minded: secure-by-design thinking, OAuth/OIDC, and data protection appropriate to banking.
• Rigorous about quality: you design for verifiability and verify rather than assume.
• Regulated-industry experience, with banking or FinTech a major bonus.
• Cloud experience: GCP preferred, with AWS or Azure also welcome, plus familiarity with IaC, containers, and CI/CD.
• Nice to have: Python/FastAPI, React/TypeScript, the GCP stack, privacy-enhancing technology or applied cryptography (MPC especially), multi-tenant SaaS, and the anti-financial-crime domain.
