This is not a traditional Senior Staff Engineer role.

We are seeking a Senior Staff Engineer who views technical leadership as the creation of leverage and enterprise-grade trust at global scale.
Your Mission:
Architecting DeepL’s Revenue Flywheel for Global Scale

You will be a key architect driving the Convert & Scale track, which is the foundational business layer of DeepL used by all our product teams. Your work will directly enable our journey from serving individual users to managing relationships with the world’s largest enterprises, involving thousands of users, complex licensing, and multi-layered access controls.

Whether you’ve been part of a startup or have worn multiple hats, your entrepreneurial mindset will thrive here. We need someone who can rapidly assess complex business needs, design the simplest, most resilient architecture to meet them, and take full ownership of the outcome.

At DeepL, you will be building the architecture for the next decade of enterprise adoption. Your focus will be on solving novel problems unique to a high-growth, AI-first platform.

• Deep Impact: You will be part of a small team of ultimate technical owners of our revenue generation platform. Your decisions will directly influence our global P&L and growth trajectory
• The Enterprise Problem: We are tackling the immense complexity of scaling a global SaaS platform for AI. Convert & Scale builds tools and services for DeepL developers to help them implement identity, monetization, and overall enterprise readiness
• Operating at AI-Native Speed: For our business systems to keep pace with our product innovation, we need technical leaders who can operate at AI-native speed. This requires thinking out of the box about AI coding tool integration, MCP, internal developer portals, and developer-friendly internal APIs that abstract away complexity and boost velocity across all engineering tracks
