Meet the team behind this journey

You will be working as part of the Convert & Scale Track (CAST) in DeepL\’s engineering department, specifically in the fields of Subscription Management and Sales Automation.

CAST\’s mission is to accelerate DeepL\’s growth by maximising the number of people that buy DeepL products and by enabling our customers to scale to any size. We are 50 people working on diverse topics ranging from identity and subscription management to customer onboarding and expansion. Currently we are looking to strengthen our team in the area of subscription management, with the goal of improving our sales-assisted customer acquisition and expansion flows through automation.

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.

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 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 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 experiences and backgrounds.

• Product mindset: you develop solutions with the customer in mind and iteratively improve your solutions based on data and feedback. You understand how to experiment and track usage for learning.

• You are a role model for continuous delivery. You build incrementally in small batches, practice trunk-based development, and pair-program by default to maintain throughput and team cohesion.

• Comfortable with a hybrid working model and able to come into our London office regularly (2x per week average).

• Fluent in English.

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.

• 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!
