Staff Software Engineer | Developer Experience

Join DeepL as a Staff Software Engineer to enhance the Developer Experience for its engineering team while leveraging cutting-edge AI technology.

• Own technical direction for a significant part of the Developer Experience mandate. Identify where the biggest friction sits for our engineers, form a clear position on how to remove it, and see that work through to adoption.
• Lead initiatives that lift developer productivity across multiple engineering teams, by understanding and improving processes and tooling, and by drawing on both established software engineering practice and AI capability.
• Design and build the workflows and tooling that carry a change through the software development lifecycle, from local development through review to release.
• Lead our work on AI across that lifecycle. Evaluate what genuinely helps, build the guardrails that make it safe and useful at our scale, and be candid about what does not work.
• Treat internal developers as customers and grow a community around developer experience. Talk to them, watch where they struggle, and let evidence decide what to build and whether it landed, whether that evidence is survey data, delivery metrics or support load. Empower product teams to own their delivery journey, and turn consensus across engineering into shipped change. Much of the work at this level is influence without authority.
• Define standards that hold across the track and drive migrations to them, bringing teams along with a working path rather than a deadline.
• Mentor engineers across the track and raise the technical bar of the group, through design reviews, architecture decisions and the everyday habits that keep systems maintainable.
• Share in operating what we build, including a sustainable on call rotation for the services and tooling other teams rely on.

• Measuring developer productivity credibly, through DORA, developer surveys, or your own defensible approach.
• Having built or operated AI-assisted developer tooling: code review, agents, MCP servers, or evaluation of any of the above.
• Experience building an internal developer platform or portal, especially with Backstage.
• Community building you can point to. Open source maintainership, a guild or community of practice, developer advocacy, or any place you have grown adoption and ownership rather than mandated it.
• GitLab or comparable CI and CD at scale, and build system work on large polyglot codebases. Runner fleets, pipeline performance, caching and artifacts, and compile and test time optimisation.

• 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.
• Monthly full-day hacking sessions: every month, we have Hack Fridays, where you can spend your time diving into a project you're passionate about and get the opportunity to work with other teams–we value your initiatives, impact, and creativity.
• 30 days of annual leave: we value your peace of mind. With 30 days off (excluding public holidays) and access to mental health resources, we make sure you're as strong mentally as you are professionally.
• Competitive benefits: just as our team spans the globe, so does our benefits package. We've crafted it to reflect the diversity of our team and tailored it to align with your unique location, to ensure you feel supported every step of the way.
