Job description

An established trading firm is looking for a talented Production Engineer to join its technology team in London.

The business operates in a fast-paced, technology-driven financial environment where reliable, high-performing systems are essential to day-to-day operations. With a strong emphasis on engineering, automation and continuous improvement, the firm offers the opportunity to work on complex technical challenges alongside a collaborative and highly skilled team.

This is a varied, hands-on engineering role combining elements of Site Reliability Engineering (SRE), Linux systems engineering, production infrastructure, automation and software development.

You’ll work closely with software engineers, infrastructure specialists and other technical stakeholders to maintain and improve critical production systems, investigate complex technical issues and develop tools and solutions that improve reliability, performance and operational efficiency.

The position would suit someone from an SRE, DevOps, Production Engineering, Linux Systems Engineering or similar background who enjoys solving challenging technical problems, working with production environments and building automation to improve how systems operate.

Responsibilities

• Maintain and improve the reliability, stability and performance of critical production systems and applications.
• Investigate and troubleshoot complex technical issues, identify root causes and implement sustainable engineering solutions.
• Develop automation, scripts and internal tooling to improve operational efficiency and reduce manual intervention.
• Work closely with software engineering teams to support the deployment, maintenance and ongoing improvement of production applications.
• Support Linux-based environments, containerised applications and associated infrastructure.
• Assist with software deployments, system upgrades and infrastructure changes.
• Develop scripts and utilities to improve monitoring, troubleshooting and system management.
• Monitor system performance, proactively identify potential issues and contribute to improvements in system resilience.
• Collaborate with developers, infrastructure engineers and other technical teams to resolve complex production challenges.
• Improve deployment processes, monitoring capabilities and operational practices.
• Support the introduction of new technologies and enhancements to existing platforms.
• Take ownership of technical problems and contribute to a culture of engineering excellence and continuous improvement.

Requirements

• Experience in Site Reliability Engineering (SRE), Production Engineering, DevOps, Linux Systems Engineering or a similar technical role.
• Strong knowledge of Linux operating systems, including experience working with production environments.
• Experience with containerisation and orchestration technologies.
• Scripting or programming experience, ideally using Python and Bash.
• Familiarity with monitoring, logging and observability tools.
• Strong troubleshooting, debugging and analytical problem-solving skills.
• Good understanding of networking fundamentals.
• Experience supporting, maintaining or improving business-critical production systems.
• Ability to work effectively with software engineers, infrastructure specialists and other technical teams.
• Strong communication skills and a proactive, engineering-led approach to solving problems.
• A willingness to learn new technologies and take ownership of technical challenges.
• Experience working in financial services, trading, fintech or another technically demanding production environment.
• Familiarity with cloud or on-premises infrastructure.
• Experience with CI/CD pipelines, deployment automation and release processes.
• Exposure to distributed systems, high-performance infrastructure or latency-sensitive applications.
• Experience working with databases or data processing technologies.
• Knowledge of infrastructure automation or configuration management tools.
• Experience improving monitoring, observability, system resilience or operational processes.
• Exposure to software development or building internal engineering tools.

Previous experience within financial services or trading is not essential. The firm is primarily interested in engineers with strong Linux fundamentals, solid troubleshooting skills, an interest in automation and the ability to work effectively within complex production environments.

Why Apply

• This is an opportunity to join an established trading business where technology plays a central role in its operations.
• You’ll gain exposure to challenging engineering problems, business-critical production systems and modern infrastructure, working alongside experienced engineers in a collaborative technical environment.
• The role offers a varied mix of production engineering, infrastructure, automation and software development, with opportunities to take ownership of technical challenges and contribute to meaningful improvements across the technology platform.
• A competitive salary and benefits package is offered, alongside opportunities for continued technical development and career progression.
