The Role: Senior Backend Engineer C++

We’re looking for Senior Backend Engineers to join two closely collaborating platform teams responsible for our core text backend services. The teams build these services by integrating advanced neural networks from our research department. Team one is focused on providing APIs to other teams and our customers, with a particular focus on implementing API requests using neural network inference jobs. Team two focuses on efficiently scheduling these inference jobs on our neural network infrastructure using a custom load balancer that dynamically optimises for latency and throughput. Both teams work closely with the research department to provide state-of-the-art AI technologies to other teams within the company and to our end users.

Responsibilities

  • Design, implement, test and maintain reliable, scalable and efficient back-end services for DeepL’s products in C++.
  • Ensure stable operation in our production environment, e.g. by investigating issues.
  • Take responsibility for interfaces, functionality or entire services, e.g. by evolving shared interfaces.
  • Identify and anticipate requirements for our services; work with your team to meet them, e.g. by solving interesting algorithmic challenges or improving the architecture.

Qualities We Look For

  • Senior Engineer with several years of relevant software development experience.
  • Strong proficiency in modern C++ (ideally C++20 and above).
  • Strong knowledge of asynchronous programming.
  • Solid understanding of computational complexity and common data structures.
  • Effective and pragmatic: ability to balance ‘perfect’ and ‘good enough’ depending on priorities and business impact.
  • Strong team player, experienced in working across: leading, contributing and collaborating.
  • Curious about learning and understanding technologies, whether programming languages, libraries, tools or systems.
  • Fluent in English. Knowledge of other languages an advantage.

Ideally, You Also Have

  • Experience in developing web services (HTTP, gRPC ...).
  • Experience in deploying services to Kubernetes.
  • Experience in operating large-scale, high-reliability architectures.
  • Knowledge of other programming languages (e.g. Python, C#, Go, ...).

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.
  • Open Communication, Regular Feedback: As a language-focused company, we value the importance of clear, honest communication.
  • Hybrid Work, Flexible Hours: We offer a hybrid work schedule, with team members coming into the office twice a week.
  • Regular In-Person Team Events: We bond over vibrant events that are as unique as our team.
  • 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.
  • 30 Days of Annual Leave: We value your peace of mind.
  • Competitive Benefits: Just as our team spans the globe, so does our benefits package.

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!
