Meet the team behind this journey Our Customization team’s mission is to deliver the features these teams need, ensuring smoother, faster processes and reducing the need for multiple external tools. By offering intuitive customization features that both enable formatting and styling communication, and enforcing guidelines for compliance, we drive habit‑formation and retention, making DeepL the go‑to platform for all content refinement tasks.
Role Overview In this role, you will partner with product managers, designers, researchers, and fellow engineers to design and maintain the backend services powering our customization features. As a Backend Engineer, you’ll build scalable systems using C# and .NET Core to enable these features across our products – Translate, Voice, and APIs. You’ll shape the technical architecture underpinning customization workflows and ensure enterprise users can efficiently deliver high‑quality content.
Your Responsibilities
Design, implement and maintain features in our microservices in a hybrid cloud environment.
Contribute to the implementation of end-to-end solutions: design, build and deliver in collaboration with multiple engineering teams.
Increase the maintainability, reliability, and robustness of our software.
Continuously improve and automate our development processes.
Contribute to our backend developer community and share knowledge within and across teams.
Take total ownership of the work you deliver, from testing and QA to post‑deployment monitoring and incident resolution.
Participate in our on‑call rotation to ensure the reliability and availability of our services.
Qualities we look for
Proficiency in a modern programming language with solid experience in backend development. Exposure to or familiarity with our tech stack (C#, .NET Core, gRPC) or similar technologies is beneficial but not a strict requirement.
Experience in building and maintaining business‑critical applications.
Solid understanding of algorithmic complexity and common data structures.
Effective and pragmatic: able to weigh “perfect” and “good enough” depending on priorities and business impact.
Ability to explain complex ideas and designs to developers and stakeholders with a wide variety of experiences and backgrounds.
Product mindset: you develop solutions with the customer in mind and iteratively improve based on data and feedback.
Role model for continuous delivery: you build incrementally in small batches, practice trunk‑based development, and pair‑program by default.
Comfortable with a hybrid working model and able to come into our London office regularly (2× per week average).
Fluent in English.

Diverse and internationally distributed team. We have employees in the UK, Germany, the Netherlands, Poland, the US, and Japan, and we continue to expand our network.
