Responsibilities
- Ship User-Facing Features: You will build and refine the interfaces for our mobile and web apps. You will ensure that when a user speaks, the translation appears instantly and clearly on the screen.
- Integrate Real-Time APIs: You will hook up our frontend applications to our Voice API, handling real-time data streams (WebSockets/gRPC) and managing connection states gracefully on unstable networks.
- Optimize for Performance: You will hunt down milliseconds. You will use profiling tools to ensure our React components render instantly and our backend services process audio chunks efficiently.
- Collaborate & Learn: You will participate in code reviews and pair programming sessions. You will ask "Why?" when you see a design choice you don't understand, and you will use AI tools to speed up your boilerplate coding so you can focus on the hard logic.
- QUALITIES WE LOOK FOR
- High Learning Trajectory (High Slope): You are excited by hard technical problems. You want to understand how WebRTC works, how LLMs process audio, and how to build apps that feel "instant."
- Full-Stack Curiosity: You are comfortable working with React/TypeScript on the frontend and C# or Python on the backend. You aren't afraid to touch a part of the stack you haven't seen before.
- User Empathy: You understand that our users are often in high-pressure situations (business meetings, frontline customer service). You build software that is robust, simple, and reliable.
- Bias for Action: You embrace the startup speed. You prefer to ship a working prototype and iterate based on feedback rather than spending weeks on a perfect design that never sees the light of day.
- 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.
- A Note on Our Hiring Process: DeepL hires for the Company, not just a specific team. We operate a Unified Engineering Pipeline. If you pass our bar, we will match you to the highest-priority role that fits your skillset—whether that is in Core Product, Platform, Voice, or Enterprise. We prioritize "Missionaries" who want to solve the biggest problems, wherever they live in the stack.
Benefits
- 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.
