Meet the team behind this journey
You will join the Hybrid Platform Engineering track, which builds and operates the compute layer underpinning DeepL's products and research: the Kubernetes control plane, node lifecycle, networking, storage and core cluster services, across both on-prem and cloud infrastructure. Today that spans hybrid infrastructure in Europe - including large on-prem GPU clusters powering DeepL's research and hundreds of on-prem GPU nodes serving production inference - as well as AWS regions across the globe running the product. The track is deepening this hybrid model, unifying how workloads run across on-prem hardware and AWS to give product and research teams a self-service foundation they can build on.

Your responsibilities

• Take ownership of the reliability, capacity and cost efficiency of DeepL's compute infrastructure, CPU and GPU: the hybrid platform serving our products across AWS and on-prem, and the on-prem clusters powering our research, including their hardware lifecycle

• Shape the platform's architecture: bring strong technical positions, weigh them on their merits with your peers, and commit to decisions serving the best outcome

• Design, build and operate production-grade Kubernetes clusters across cloud and on-prem infrastructure, taking them from design through to long-term operation

• Drive the technical work of deepening the hybrid model - unifying how workloads run across on-prem hardware and cloud, especially AWS and supporting research as it adopts cloud-native technology and ways of working

• Define infrastructure-as-code and platform standards that hold across the track, and strengthen observability and security so the platform's behaviour is legible to the teams that depend on it

• Mentor engineers across the infrastructure track and raise the technical bar of the group, through design reviews, architecture decisions and the everyday habits that keep the platform maintainable

• Build consensus across engineering teams and turn it into shipped change, shaping platform direction at track level

• Lead incident response for hybrid infrastructure, driving remediation through to root cause, and help sustain an on-call rotation the team can carry for the long term

What you bring to the table

• Deep, hands-on Kubernetes expertise: you have designed, built and operated clusters at scale, through their full lifecycle

• Depth at scale in either public cloud or on-prem infrastructure, plus the credibility to work in the other. AWS experience is preferred, and bare-metal or data centre experience is strongly valued

• Networking and Linux depth you can debug with: you can follow a problem from a container through the host to the network edge

• Infrastructure as code with Terraform or equivalent, and GitOps delivery with tooling such as ArgoCD, applied to environments you have owned in production

• Software engineering skills in at least one major language, Go or Python preferred, at the level of building tooling other engineers rely on

• A track record of technical ownership spanning several teams: you create clarity where a mandate crosses team boundaries, hold clear technical positions, change them on evidence and carry other engineers with you

• Strong incident-management and reliability-engineering discipline, and the ownership mindset to build more resilient systems

You’d get bonus points for

• GPU infrastructure for training or inference at scale

• Distributed storage systems in production, such as Ceph

• Having served researchers or data scientists as platform customers

• Networking at BGP level in a hybrid or on-prem environment

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.…
