What you'll do
Drive Enterprise API Adoption: You will own the features that turn enterprise interest into deep, durable adoption. Examples include usage insights, cost and consumption controls, and the governance tooling that lets large organizations understand and manage how they use DeepL's APIs
Build for Governance & Compliance: You will design the controls enterprise IT and security admins rely on (roles and permissions, projects, data residency, and audit-ability), making DeepL the compliant default for regulated, global organizations
Guardianship of Quality & Production Reliability: You will own your services end-to-end, including participation in the API on-call rotation, with a shared goal of taking our public API to four nines of reliability. You will implement strong contract testing, monitoring, and SLOs, preventing breaking changes and security vulnerabilities before they reach our enterprise customers
Architect Across the Enterprise Ecosystem: You will work deep within DeepL's existing technical and organizational structures, navigating dependencies across different areas and many stakeholder teams to ship cohesive, reliable enterprise capabilities
An "Enterprise-First" Mindset: You treat enterprise IT and security admins as your primary users. You understand that earning their trust means clear governance, predictable cost control, robust compliance, fast response times and data residency. You're a strong communicator who's comfortable owning product decisions and implementing them
Backend Mastery at Scale (C# / .NET): You have deep expertise designing scalable backend systems, RESTful APIs, and distributed architectures, primarily in C# / .NET, and you've worked with high-scale distributed systems in production. Strong API design fundamentals and system design are core to how you work. Roughly 80-90% of the work is backend; working on the frontend (React/TypeScript) is a welcome plus, not a requirement
What they're looking for
- Enterprise Platform Fluency: You bring hands-on experience with the building blocks of modern enterprise APIs (MCP, CLIs, and OAuth) and know how to wield them to build secure, extensible integrations
- Cross-Team Leadership: You have a track record of leading projects across multiple teams. You can align with different areas and other stakeholders, manage cross-team contracts and dependencies, and keep complex, interconnected systems coherent
- Extreme Ownership & Operational Excellence: You own your services end-to-end (production operations, incident response, and on-call) and you're motivated by pushing reliability toward four nines. You write comprehensive tests, learn from incidents, and treat mature SLOs as a core engineering feature
- AI-Native Velocity: You leverage AI-powered tools (like Claude Code, Codex or GitHub Copilot) to accelerate delivery so you can focus your energy on high-value architecture and complex problem-solving
