Software Engineer - API

Responsibilities

• Build Platform Components : You will implement reusable components, contribute to documentation, and help maintain client libraries (SDKs) and starter templates that make it easier for customers and ISVs to build AI-enabled products on top of DeepL
• Write Quality Code : You will write well-tested, production-ready code and contribute to monitoring, alerting, and reliability improvements. You will participate in incident response, learn from postmortems, and help the team continuously raise the bar on code quality and operational health
• Qualities we look for
• A Developer-Centric Mindset : You think about APIs from the perspective of the developer using them. You care about clear abstractions, helpful error messages, and good documentation-not just whether the endpoint returns a 200
• Ownership and Reliability : You take responsibility for what you ship. You write tests, monitor your code in production, and follow through when things go wrong. You're proactive about flagging issues and asking for help when you need it, and you treat each incident as an opportunity to learn
• AI-Native Velocity : You leverage AI-powered tools (like GitHub Copilot or Claude) to accelerate your output and reduce repetitive toil. You use AI for boilerplate code,
