Role

Who you are

Proficiency in a modern programming language with solid experience in backend development. Exposure to or familiarity with our tech stack (C#, .NET Core, PostgreSQL, Grafana, Kubernetes, Kafka) or similar technologies would be beneficial but is not a strict requirement. What’s more important is your willingness and ability to learn new technologies quickly
Experience in building, scaling, and maintaining business-critical applications
Solid understanding of algorithmic complexity and common data structures
Effective and pragmatic; you can weigh between ‘perfect’ and ‘good enough’ depending on priorities and business impact
The ability to explain complex ideas and designs to developers and stakeholders with a wide variety of experience and backgrounds
Capacity to balance short-term deliverables with long-term product vision, ensuring product evolution aligns with user and business goals
Understanding of observability, metrics, and managing an application throughout its entire lifecycle
A user-centric mindset: deep user empathy, ownership of user data, and eagerness to make a direct impact on the user experience at DeepL
A continuous learning mindset—openness to trying different approaches and adapting to new technologies
Fluent in English
Comfortable with a hybrid working model and able to come into any of our offices regularly (2x per week average)

What the job involves

In this role, you will partner with product managers, designers, and fellow engineers to design and maintain the backend services powering our collaboration features. As a Senior Backend Engineer, your expertise in building scalable systems using modern technologies (such as C# and .NET Core) will be instrumental in enabling real-time teamwork, version management, and feedback loops.
Your contributions will help shape the technical architecture underpinning collaborative workflows, ensuring enterprise users can efficiently deliver high-quality translations and content. By continuously improving these core services, you’ll play a key part in establishing DeepL as an essential component of team-based content creation worldwide
Design, build, and maintain features within a microservices-driven architecture in a hybrid cloud environment, from early design phases to production deployment, collaborating with multiple engineering teams
Enhance software maintainability, reliability, and performance through robust coding standards, automated testing, and continuous improvement
Foster a collaborative engineering culture through pair programming, mob programming, and knowledge-sharing activities—coaching others and championing best practices
Maintain a documentation-first mindset, promoting clarity and efficient onboarding across the organization
Work closely with product managers and designers to clarify feature scope, prioritize user needs, and align solutions with product strategy
Leverage data-informed approaches—metrics, observability, usage trends—to guide engineering decisions and validate outcomes
