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 balance strategic platform architecture with tactical feature delivery, working across the stack to create delightful, frictionless experiences for both external developers and internal engineering teams. YOUR RESPONSIBILITIES - Drive "DevEx Delight": You will own and transform the experience of developers using DeepL APIs. You will streamline the entire journey—from anonymous visitor to activated developer—by building intuitive self-service experiences, seamless onboarding flows, and advanced customization interfaces . - Platform Enablement & Scale: You won't just write endpoints; you will build the ecosystem. You will create reusable components, comprehensive documentation, starter templates, and client libraries (SDKs) that empower customers and ISVs to build AI-enabled products rapidly. - Cross-Functional Architecture: You will act as the API standard-bearer across DeepL. Partnering with Enterprise (BAT), Core Text, Voice, and Customization teams, you will drive continuous improvement and maintain the highest standards for the consistency, security, and reliability of all customer-facing APIs. - Guardianship of Quality & Compliance: You will implement automated quality gates, strict contract testing, and robust monitoring infrastructure. You will prevent breaking changes and security vulnerabilities before they hit production, shaping the API design standards and operational excellence practices for our growing platform . QUALITIES WE LOOK FOR - A "Product-First" API Mindset: You treat developers as your primary users. You understand that a successful API relies on reducing cognitive load, creating clear abstractions, and providing stellar documentation, not just fast response times. - Backend Mastery & Full-Stack Capability: You have deep expertise in designing scalable backend systems, RESTful APIs, and distributed architectures (using Go, Python, Java, C#, or similar). 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. You use AI for boilerplate code, test generation, and debugging, allowing you to focus your cognitive energy on high-value architectural decisions and complex problem-solving. 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 fee
