Job description

DRW is a diversified trading firm with over 3 decades of experience bringing sophisticated technology and exceptional people together to operate in markets around the world. We value autonomy and the ability to quickly pivot to capture opportunities, so we operate using our own capital and trading at our own risk.

Headquartered in Chicago with offices throughout the U.S., Canada, Europe, and Asia, we trade a variety of asset classes including Fixed Income, ETFs, Equities, FX, Commodities and Energy across all major global markets. We have also leveraged our expertise and technology to expand into three non-traditional strategies: real estate, venture capital and cryptoassets.

We operate with respect, curiosity and open minds. The people who thrive here share our belief that it’s not just what we do that matters–it's how we do it. DRW is a place of high expectations, integrity, innovation and a willingness to challenge consensus.

We are seeking an Infrastructure Engineer to join our Fixed Income Commodities and Currency Options (FICCO) and Cumberland team in London. In this role, you will be responsible for designing, maintaining, and supporting highly available systems within a technologically diverse stack used for global research and trading of FICCO and Cryptoassets. Leveraging technologies such as Terraform, Docker, Kubernetes, CI/CD, Python, Prometheus and Grafana, you will develop repeatable and supportable infrastructure to meet the demanding needs of our business.

• Optimize and fine‑tune the latest hardware, operating systems, and cloud infrastructure to achieve maximum performance in trading and compute operations.
• Drive initiatives to modernize environments by building and optimizing infrastructure using the most appropriate tools and technologies—whether cloud‑based or on‑premise to best meet the needs of our trading systems.
• Use declarative frameworks like Terraform and Ansible to build, manage, and configure infrastructure such as AWS, Kubernetes, Git, TeamCity, Concourse, and GitHub Actions.
• Research and implement new technologies to enhance network and compute performance, container management, workload orchestration, and cloud integration.
• Support the business by maintaining and managing storage requirements on NFS, CIFS, and S3 compatible systems within a Linux‑based environment.
• Support and enhance highly available database architectures, ensuring systems are up‑to‑date with minimal downtime, following best practices, and coordinating with Database Administrators for updates and architectural improvements.
• Ensure systems are secure through regular patching and reporting, maintaining compliance with security standards.
• Consistently challenge the norm and advocate for change.

Required Skills, Experience & Abilities:

• Proven experience in supporting mission critical, high performance trading infrastructure across various technology stacks.
• Experience deploying and supporting applications in Kubernetes.
• Previous infrastructure monitoring experience using Prometheus and Grafana.
• Previous experience maintaining and optimizing cloud infrastructure in AWS environments.
• Experience performing database and database infrastructure support for highly available systems.
• Working knowledge of TLS.
• Demonstrated knowledge of network communications protocols, including multicast and WebSockets.
• Experience using Ansible and Terraform to manage infrastructure.
• Flexibility to take off‑hours support calls and meetings as needs dictate.
• Ability to learn quickly; a passion for new technology.
• Self‑motivated to continually expand skillset and improve supported systems.
