Meet the team behind this journey

Become part of a high-velocity, forward-thinking team that operates as a "startup within a company," where your ideas will directly influence product development. We seek proactive individuals who take ownership of their work and promote cross-role collaboration to get results. Our commitment leads us to foster close relationships with engaged early users—whether they are fellow DeepL employees or early external testers. We’re looking for someone who is focused on generating real value for users, beyond the AI hype.

Starting from the early days of agentic hype, we have been developing as a “tiger team” 🐯 the DeepL Agent internally and dog-fooding now to the full AI company. The DeepL Agent is a general-purpose AI agent designed to autonomously handle a wide range of business tasks through natural language instructions. From building and researching sales account lists, to translating and publishing website content – it's built to streamline the repetitive, time-consuming work you do every day.

The team is now ready to scale and grow, but you’re still early. Our ambition is big. We can’t wait to hear from you.

  • Own features from prototyping up to production readiness

  • Establish systems & rules to keep the codebase maintainable and extendable by AI or even our designer (they code too)

  • Continuously evaluate how to keep maintenance costs minimal while improving the product

  • Develop robust state management solutions

  • Partner with customers and designers to identify optimal solutions for our users

  • Write clear, testable code and verify its correctness through unit and E2E testing or ship depending on what the situation calls for

  • Work in a full-stack environment and don’t be scared of a back-end, infra and AI tooling

  • Participation in our on-call rotation: You’ll ensure the reliability and availability of our services by being available to join the team's shared on-call rotation as needed

Qualities we look for

  • Strong proficiency in TypeScript and software engineering principles.

  • Strong experience with React

  • Several years of professional experience in software/web development, working in a team environment

  • A passion for tackling challenging problems and a growth mindset, working with other engineers to drive innovative solutions and enhance product development

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.

  • 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.

  • 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.

  • 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!
