Senior Software Engineer, MLOps and Infrastructure

This job is brought to you by Jobs/Redefined, the UK's leading over-50s age inclusive jobs board. Our mission is to scale intelligence to serve humanity. We are training and deploying frontier models for developers and enterprises who are building AI systems to power magical experiences like content generation, semantic search, RAG, and agents. We believe that our work is instrumental to the widespread adoption of AI. We obsess over what we build. Each one of us is responsible for contributing to increasing the capabilities of our models and the value they drive for our customers. We like to work hard and move fast to do what's best for our customers. Cohere is a team of researchers, engineers, designers, and more, who are passionate about their craft. Each person is one of the best in the world at what they do. We believe that a diverse range of perspectives is a requirement for building great products. Join us on our mission and shape the future!

This team is responsible for building world-class infrastructure that is critical to all of Cohere's success. Focus on stability, scalability, and observability are all paramount as this work acts as the foundation for all members of technical staff. Our team optimizes for a wide range of technical skillsets. Being self-directed and adaptable, identifying and solving key problems are essential.

Please Note: All of our infrastructure roles require participating in a 24x7 on-call rotation, where you are compensated for your on-call schedule. For this role, we are targeting candidates who live in EMEA.

In order to be successful in the role, you have:

• 5+ years of engineering experience running production infrastructure at a large scale
• Experience designing large, highly available distributed systems with Kubernetes, and GPU workloads on those clusters
• Experience working with GCP, Azure, AWS and/or OCI
• Experience in designing, deploying, supporting, and troubleshooting in complex Linux-based computing environments
• Excellent collaboration and troubleshooting skills to build mission-critical systems, and ensure smooth operations and efficient teamwork
• The grit and adaptability to solve complex technical challenges that evolve day to day

Bonus qualifications:

• You worked with or supported MLEs or data scientists
• Familiarity troubleshooting RDMA networking

As a Senior Software Engineer you will:

• Build self-service systems that automate managing, deploying and operating services, including our custom Kubernetes operators that support language model deployments.
• Automate environment observability and resilience.
• Enable all developers to troubleshoot and resolve problems.
• Take steps required to ensure we hit defined SLOs, including participation in an on-call rotation.
• Build strong relationships with internal developers and influence the Infrastructure team's roadmap based on their feedback.
• Develop our team through knowledge sharing and an active review process.

You may be a good fit if:

• You have proven production experience with Kubernetes.
• You have hands-on coding experience developing services and automated tests (we use Go).
• You prefer contributing to Open Source solutions rather than building solutions from the ground up.
• You have experience scaling and debugging cloud-based infrastructure (we use Oracle, GCP, and Coreweave).
• You draw motivation from building systems that help others be more productive.
• You see mentorship, knowledge transfer, and review as essential prerequisites for a healthy team.

If some of the above doesn’t line up perfectly with your experience, we still encourage you to apply! If you want to work really hard on a glorious mission with teammates that want the same thing, Cohere is the place for you. We value and celebrate diversity and strive to create an inclusive work environment for all. We welcome applicants from all backgrounds and are committed to providing equal opportunities.
