Software Engineer | API

Your responsibilities
Contribute to Developer Experience: You will build features that improve how developers discover, onboard to, and use DeepL APIs. This includes implementing self-service flows, onboarding experiences, and configuration interfaces that reduce friction and delight developers from their first API call

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

Collaborate Across Teams: You will work closely with teammates across API Core and adjacent teams—including Enterprise, Core Text, Voice, and Customization—to deliver consistent, well-designed APIs. You will actively participate in code reviews, design discussions, and contribute to shared standards

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

Solid Backend Fundamentals with Full-Stack Curiosity: You have a good foundation in backend development, RESTful APIs, and server-side systems (using Go, Python, Java, C#, or similar). You're comfortable picking up frontend work when needed—whether that's contributing to a developer dashboard or a signup flow built in React/TypeScript

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, test generation, and debugging—freeing up your focus for solving harder problems and growing your craft

Virtual Shares - An ownership mindset in every role. We believe everyone should share in our success, and that's why every employee receives Virtual Shares, linking your contribution directly to DeepL's growth and rewarding you with a stake in our future

Regular in-person team events: we bond over vibrant events that are as unique as our team, from local team and business unit gatherings, to new-joiner onboardings, to company-wide events that bring us all together–literally

Monthly full-day hacking sessions: every month, we have Hack Fridays, where you can spend your time diving into a project you're passionate about and get the opportunity to work with other teams–we value your initiatives, impact, and creativity

30 days of annual leave: we value your peace of mind. With 30 days off (excluding public holidays) and access to mental health resources, we make sure you're as strong mentally as you are professionally

Competitive benefits: just as our team spans the globe, so does our benefits package. We've crafted it to reflect the diversity of our team and tailored it to align with your unique location, to ensure you feel supported every step of the way
