If you’re ready to shape the future of AI and grow your career in a fast-moving, purpose-driven environment, DeepL is your next destination. WHAT SETS US APART What sets us apart is our blend of cutting-edge AI technology, meaningful work, and a culture where people truly thrive. We’re a team of innovators, researchers, and creators driven by a shared purpose to unlock human potential by making work simpler, smarter, and more connected. When we share what it’s like to work at DeepL, the reactions are overwhelmingly positive. This might be because of our technology that helps millions of people and businesses communicate and work better every day, or because of the trust, curiosity, and care that shape our culture. What we know for sure is this: being part of DeepL means joining a team dedicated to innovation, growth, and well-being. Discover more about life at DeepL onLinkedIn,Instagram, and our Blog. MEET THE TEAM BEHIND THIS JOURNEY DeepL is not just a translation tool; we are building the Operating System for Global Communication. We are the rare AI company that builds the entire stack in-house: from training next-gen LLMs on our own NVIDIA DGX SuperPODs to delivering real-time Language AI to over 100 million users and 200,000+ businesses globally. You will join the API Core team. For us, the API is the product. We are the bridge connecting DeepL's bleeding-edge AI capabilities to developers worldwide. We focus on Developer Experience (DevEx), API platform infrastructure, and enabling our internal product teams to launch world-class APIs quickly and independently. We are shifting gears from "Software-First" to "Product-First." We don't hire engineers to simply maintain legacy endpoints or close Jira tickets. We hire Missionaries—builders who obsess over the Why before the How. You will contribute across the stack, shipping features that create delightful, frictionless experiences for both external developers and internal engineering teams. 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 WHAT WE OFFER * Diverse and internationally distributed team: joining our team means becoming part of a large, global community with people of more than 90 nationalities. We're more than just colleagues; we're a group of professionals with a shared mission to connect diverse cultures. Our global presence is growing–we've doubled in size nearly every year, with our employees based in the UK, Germany, the Netherlands, Poland, the US, and Japan, and we continue to expand our network * Open communication, regular feedback: as a language-focused company, we value the importance of clear, honest communication. We value smooth collaboration, direct and actionable feedback, and believe that leading with empathy and growth mindset makes us better together * Hybrid work, flexible hours: we offer a hybrid work schedule, with team members coming into the office twice a week. This allows you to engage directly with your team and experience the unique energy of our workspace, while still enjoying the flexibility and comfort of working from home. With flexible working hours and trust in your productivity, we are in sync with your team's general locations and time zones to foster effective and seamless collaboration * 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 If this role and our mission resonate with you, but you're hesitant because you don't check all the boxes, don't let that hold you back. At DeepL, it's all about the value you bring and the growth we can foster together. Go ahead, apply—let's discover your potential together. We can't wait to meet you! #LI-HK1 WE ARE AN EQUAL OPPORTUNITY EMPLOYER You are welcome at DeepL for who you are - we appreciate authenticity here.

You are also comfortable crossing the stack, using modern frontend frameworks (React/TypeScript) to build developer-facing dashboards, signup flows, and configuration UIs. * Extreme Ownership & Operational Excellence: You have a track record of owning services end-to-end. You don't just ship code; you own production operations, incident response, and continuous improvement. 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 GitHub Copilot or Claude) to accelerate your velocity and eliminate repetitive toil.
