About the company

We’re working with a highly sophisticated technology-driven firm operating at the intersection of software engineering and quantitative research.

From their London headquarters, they bring together engineers and researchers to solve complex, high-stakes problems, with a strong emphasis on rigorous thinking, long-term value creation, and technical excellence.

The company is building a world-class platform designed to support advanced research and real-time decision-making, with engineering at the core of its success.

The opportunity

This is a high-impact role focused on production engineering within a complex, distributed environment.

You’ll be responsible for improving system reliability, observability, and operational efficiency across a federated engineering platform. The work directly supports real-time systems where performance, stability, and change safety are critical.

The role is hands-on and collaborative, working closely with engineering, infrastructure, and research teams to ensure systems are robust, scalable, and safe to evolve.

What you’ll do

• Improve resilience and performance of real-time distributed systems
• Identify bottlenecks, reduce operational overhead, and limit failure impact
• Build tooling and frameworks to enable frequent, low-risk software delivery
• Design and maintain observability systems, including metrics, alerting, and diagnostics
• Develop systems for deployment automation, runtime management, and release readiness
• Drive best practices across reliability, fault tolerance, and service ownership
• Collaborate across multiple engineering teams to align on production standards
• Participate in production support, incident response, and continuous improvement
• Work with application and research teams to define SLAs and runtime boundaries

You should have

• Strong software engineering background, ideally in distributed or real-time systems
• Experience with containerisation and orchestration (e.g. Kubernetes)
• Familiarity with observability tooling (e.g. Prometheus, Grafana, OpenTelemetry)
• Strong debugging and problem-solving skills in complex systems
• Experience building or contributing to high-availability, fault-tolerant platforms
• Understanding of CI/CD systems and deployment automation
• Ability to operate across multiple teams in a federated environment
• Focus on improving systems through engineering rather than manual processes

Tech environment

• Distributed, real-time systems at scale
• Containerised infrastructure and orchestration
• Observability stack including metrics, tracing, and alerting systems
• CI/CD pipelines and automated deployment systems
• Strong emphasis on reliability, performance, and operational safety

Why it’s compelling

• Work on complex, high-impact systems with real-world consequences
