Senior Software Engineer | API

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.

Responsibilities

• Drive "DevEx Delight": Own and transform the experience of developers using DeepL APIs. 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: Build reusable components, comprehensive documentation, starter templates, and client libraries (SDKs) that empower customers and ISVs to build AI-enabled products rapidly.
• Cross-Functional Architecture: Act as the API standard-bearer across DeepL. Partner with Enterprise (BAT), Core Text, Voice, and Customization teams to drive continuous improvement and maintain the highest standards for the consistency, security, and reliability of all customer-facing APIs.
• Guardianship of Quality & Compliance: Implement automated quality gates, strict contract testing, and robust monitoring infrastructure. 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: Treat developers as your primary users. 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: Have deep expertise in designing scalable backend systems, RESTful APIs, and distributed architectures (using Go, Python, Java, C#, or similar). Comfortable crossing the stack, using modern frontend frameworks (React/TypeScript) to build developer-facing dashboards, signup flows, and configuration UIs.
• Extreme Ownership & Operational Excellence: Own services end-to-end. Write comprehensive tests, learn from incidents, and treat mature SLOs as a core engineering feature.
• AI-Native Velocity: Leverage AI-powered tools (like GitHub Copilot or Claude) to accelerate your velocity and eliminate repetitive toil. Use AI for boilerplate code, test generation, and debugging, allowing you to focus on high-value architectural decisions and complex problem-solving.

What We Offer

• Diverse and internationally distributed team: Join a large, global community with people of more than 90 nationalities. Engage with a diverse group of professionals with a shared mission to connect diverse cultures.
• Open communication, regular feedback: Value clear, honest communication. Embrace smooth collaboration, direct and actionable feedback, and lead with empathy and a growth mindset.
• Hybrid work, flexible hours: Offer a hybrid work schedule, with team members coming into the office twice a week. Enjoy the flexibility and comfort of working from home with flexible working hours and trust in your productivity.
• Virtual Shares - An ownership mindset in every role: Receive Virtual Shares, linking your contribution directly to DeepL’s growth and rewarding you with a stake in our future.
• Regular in-person team events: 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.
• Monthly full-day hacking sessions: Dive into a project you're passionate about and work with other teams. We value your initiatives, impact, and creativity.
• 30 days of annual leave: Enjoy 30 days off (excluding public holidays) and access to mental health resources. Ensure you're as strong mentally as you are professionally.
• Competitive benefits: Crafted to reflect the diversity of our team and tailored to align with your unique location, ensuring you feel supported every step of the way.
