Meet the team behind this journey
You will join DeepL Voice, the team building the future of real-time communication. We are the team behind Voice for Meetings and Voice for Conversations—products that allow people to speak in their native language and be understood instantly by anyone, anywhere.
This is not a standard web development role. You will be working at the bleeding edge of Language AI, building the interfaces and systems that power live translation. We are a fast-moving team with the energy of a startup and the resources of a global AI leader. We are solving problems that haven't been solved before, like creating stable, flicker-free text streams in real-time and integrating next-gen Text-to-Speech models.
As a Software Engineer in Voice, you won't just be fixing bugs. You will be shipping features that define how the world communicates. You will learn from Senior Staff Engineers and Researchers, growing your skills in high-performance streaming, AI integration, and product engineering.
Your Responsibilities
This is not a standard web development role. You will be working at the bleeding edge of Language AI, building the interfaces and systems that power live translation. We are a fast-moving team with the energy of a startup and the resources of a global AI leader. We are solving problems that haven't been solved before, like creating stable, flicker-free text streams in real-time and integrating next-gen Text-to-Speech models.
As a Software Engineer in Voice, you won't just be fixing bugs. You will be shipping features that define how the world communicates. You will learn from Senior Staff Engineers and Researchers, growing your skills in high-performance streaming, AI integration, and product engineering.
Your 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.
- 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.
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.
We are an equal opportunity employer
You are welcome at DeepL for who you are—we appreciate authenticity here. Our product is for everyone, and so is our workplace. The more voices we have represented and amplified in our business, the more we will all succeed, contribute, and think forward! So bring us your personal experience, your perspectives, and your background. It’s in our diversity that we will find the power to break down language barriers in the world.
