Our journey is built on DeepL’s reputation for world-class translation quality, trusted by millions of users and leading enterprise customers worldwide. At the heart of this next chapter is the Expert Editor team, focused on extending and enriching the capabilities of DeepL’s core translation experience.

The mission of the Expert Editor team is to design and build a sophisticated editing platform that expands upon our existing translator. This product enables granular, segment-level control over translations and supports a broad range of input formats, including plain text, documents, audio, and video. By doing so, we empower users to adapt translations with precision, flexibility, and confidence across diverse use cases.

We work closely with cross-functional partners across Workflows, Core Editor, Customisation, and Research, collaborating to deliver high-quality, scalable solutions. Success in this team relies on strong communication, thoughtful planning, effective prioritisation, and a high degree of team fluidity. We value end to end ownership and teamwork, always striving to win together while maintaining the quality standards that define DeepL.

Looking ahead, the Expert Editor is a pivotal platform for the future of translation at DeepL. It will enable multiparty collaboration, supporting both casual and expert review workflows, and serve as a foundation for more advanced, collaborative, and enterprise-ready editing experiences.

• Own features end-to-end: You'll independently deliver medium-complexity features from design through production, breaking down work effectively and meeting delivery expectations with minimal oversight

• Drive customer impact: You'll ensure your work is relevant and maintainable, using data and stakeholder feedback to validate impact and suggest improvements that enhance user experience

• Build PoCs to create certainty: When faced with ambiguous technical challenges, you'll prototype solutions and run experiments (A/B tests, gradual rollouts) to validate approaches before committing to full implementation

• Challenge requirements proactively: You'll apply product and technical context to make better design decisions, questioning unclear requirements and confirming we're solving the right customer problems

• Collaborate cross-functionally: You'll communicate clearly across teams, unblock others, and share knowledge through documentation that helps teammates understand and build on your work

• Support and mentor others: You'll help engineers grow, engage constructively in team rituals, and identify opportunities to improve how the team delivers

• Adapt to evolving priorities: You'll stay flexible as requirements shift, escalate risks early, and maintain momentum while learning new tools and patterns

• Share operational responsibility: You'll participate in on-call rotations as needed, taking ownership of your code in production and debugging issues independently

• Product engineering mindset: You obsess about customer experience and solving real user problems. You balance pragmatism with technical rigor, asking "should we build this?" and connecting your work to measurable business outcomes

• Comfort with ambiguity: You thrive when problems lack clear solutions. Rather than waiting for perfect clarity, you build PoCs and run experiments to create certainty and de-risk ambiguous projects

• Willingness to take risks: You're eager to try new approaches and technologies, learning quickly from both successes and failures. You validate assumptions through experiments rather than building large solutions upfront

• Solid engineering foundations: You write clean, maintainable code with strong testing practices. You use core tools and patterns independently, consistently delivering work with minimal issues

• Collaborative communicator: You're a clear communicator and active listener who helps others succeed. You document your work effectively and contribute positively to team health through constructive feedback

• Growth-oriented: You actively seek feedback, set development goals, and stay curious about industry advancements. You're open to learning new tools and technologies when the problem demands it

• 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.

If this role and our mission resonate with you, but you're hesitant because you don't check all the boxes, don't let that hold you back. At DeepL, it's all about the value you bring and the growth we can foster together. Go ahead, apply—let's discover your potential together. We can't wait to meet you!
