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 300 million users and 200,000+ businesses globally.

We are shifting gears. We are moving from "Software-First" to "Product-First." We don't hire engineers to just close tickets or optimize algorithms in isolation. We hire Missionaries - builders who obsess over the Why before the How.

As a Software Engineer at DeepL, you will join a high-performance culture where "good enough" isn't enough. You won't be treated as a "junior" who only fixes bugs; you will be a core contributor shipping user-facing features, collaborating with Senior Engineers, and growing your skills at the speed of our scale. We are looking for engineers with a "high slope" - builders who learn fast, ship often, and care deeply about the product they build.

YOUR RESPONSIBILITIES

- Ship Features, Not Just Code: You will own the implementation of end-to-end features. You won't just write functions in isolation; you will ensure your code solves the actual user problem, works in production, and is covered by robust tests.

- Collaborate to Raise the Bar: You will actively participate in pair programming, code reviews, and technical discussions. You aren't afraid to ask for help, but you also aren't afraid to challenge a design if you think there is a better way.

- Leverage Modern Tooling: You will use AI-assisted tools (like Copilot and Claude) to handle boilerplate and refactoring, allowing you to focus on logic and product value. We value engineers who use the best tools to ship faster.

- Build for Quality: You will write clean, maintainable code that your future self (and your team) will thank you for. You understand that "speed" doesn't mean "sloppy" - it means building reliable software that doesn't break at 2am.

QUALITIES WE LOOK FOR

- A "Product-First" Mindset: You care about who uses your software. You ask questions about the feature requirements and suggest improvements, rather than blindly following a spec.

- High Learning Trajectory (High Slope): You might not know everything yet, but you learn incredibly fast. You are curious about the full stack - from the database query to the React component - and you actively seek out hard problems to grow.

- Strong Engineering Fundamentals: You have a solid grasp of data structures, algorithms, and clean coding principles. You can take a complex logic problem and break it down into small, solvable pieces.

- Adaptability: We use C#/.NET Core, Python, React, and Kubernetes. We don't expect you to be an expert in all of them today, but we expect you to be willing to jump in and learn whatever tool gets the job done.

- 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
