DevOps Engineer in City of London

We are seeking a talented and experienced DevOps Engineer to join our team. This engineer will contribute to the further development of Arena, a web-based software platform for reinforcement learning training and RLOps. As a DevOps Engineer, you will be responsible for designing, implementing, and maintaining the cloud infrastructure, CI/CD pipelines, and deployment systems that enable businesses to build and deploy reinforcement learning models at scale.

Responsibilities

• Design and maintain robust, scalable cloud infrastructure to support high-performance reinforcement learning workloads and distributed training environments.
• Build and optimise CI/CD pipelines for both our open-source framework and Arena enterprise platform, ensuring reliable deployments and automated testing.
• Implement and manage containerisation strategies using Docker and Kubernetes for ML model training, deployment, and orchestration.
• Develop infrastructure as code (IaC) solutions using tools like Terraform, CloudFormation, or Pulumi to ensure reproducible and version-controlled infrastructure.
• Monitor system performance, implement alerting and logging solutions, and troubleshoot production issues across distributed ML training environments.
• Collaborate with ML engineers to optimise resource allocation and cost efficiency for compute-intensive RL training workloads.
• Implement security best practices, manage access controls, and ensure compliance with enterprise security requirements.
• Automate operational tasks including backup strategies, disaster recovery procedures, and system maintenance.
• Support the deployment and scaling of GPU clusters and distributed computing resources for reinforcement learning applications.
• Maintain high availability and performance of production systems serving ML models to external customers.

Requirements

• Bachelor's degree or higher in Computer Science, Engineering, or a related field, or 3+ years of relevant DevOps/infrastructure experience.
• Strong experience with cloud platforms (AWS, GCP, Azure) and their ML/AI services, with expertise in managing compute-intensive workloads.
• Proficiency in containerisation technologies (Docker, Kubernetes) and container orchestration for ML workloads.
• Experience with Infrastructure as Code tools (Terraform, CloudFormation, Pulumi) and configuration management.
• Solid understanding of CI/CD principles and tools (GitHub Actions, GitLab CI, Jenkins) with experience in ML pipeline automation.
• Knowledge of monitoring and observability tools (Prometheus, Grafana, OpenObserve) and their application to ML systems.
• Experience with GPU infrastructure management and distributed computing frameworks for machine learning.
• Familiarity with MLOps practices and tools for model deployment, versioning, and lifecycle management.
• Strong scripting skills in Python, Bash, or similar languages for automation tasks.
• Understanding of networking, security, and database management in cloud environments.
• Experience with high-performance computing environments and job scheduling systems is a plus.
• Knowledge of machine learning workflows and the unique infrastructure requirements of ML training and inference.
• Strong problem-solving skills and ability to work in a fast-paced, collaborative environment.
• Excellent communication skills and experience working with cross-functional teams.

Compensation

• Competitive salary + significant stock options.
• 30 days of holiday, plus bank holidays, per year.
• Flexible working from home and 6‑month remote working policies.
• Enhanced parental leave.
• Learning budget of £500 per calendar year for books, training courses and conferences.
• Company pension scheme.
• Regular team socials and quarterly all-company parties.
• Bike2Work scheme.
