Job description

Referment is working with a global financial-services technology company offering a transaction payments platform and APIs covering embedded finance, payment accounts, FX, rapid payouts and physical and virtual card issuing. A regulated e-money institution operating in the UK and Europe, it is part of a wider financial-technology group and delivers API-driven payments infrastructure to corporate and fintech clients.

You will join the technical operations team as a Senior DevOps Engineer, reporting to the Technical Operations Manager, and take a key role in the evolution of the cloud platform and payments infrastructure. The position offers genuine influence over engineering standards, cloud architecture and platform strategy across a business delivering API-driven payment and card solutions. The team has fully embraced AI-assisted engineering and wants people who will push that further rather than merely tolerate it.

The Role

• Own and evolve cloud infrastructure across production and non-production environments.
• Integrate AI tooling into daily engineering workflows - code, infrastructure and incident response - as a default way of working.
• Design and implement Infrastructure as Code standards and build scalable CI/CD pipelines to accelerate delivery.
• Drive platform reliability, observability and operational excellence, implementing monitoring, logging and alerting frameworks for critical applications.
• Lead incident response, root-cause analysis and platform improvements.
• Ensure infrastructure meets security, governance and compliance requirements, and support business continuity, disaster recovery and high-availability initiatives.
• Champion DevOps culture and mentor engineers on cloud, automation and DevOps practices.

What We're Looking For

• Genuine, demonstrated enthusiasm for AI-assisted engineering - daily use of tools like Claude Code, Copilot or equivalent as a core part of how you work.
• Significant experience in a Senior DevOps, Platform Engineering or Site Reliability Engineering role.
• Deep expertise in public cloud infrastructure, strong Kubernetes and containerisation experience, and proven IaC with Terraform or similar.
• Experience designing and maintaining enterprise-grade CI/CD pipelines.
• Strong understanding of networking, security and cloud architecture, with a track record of improving reliability and operational performance.

Desirable

• Experience with PCI-DSS, SOC2 or similar regulatory frameworks.
• Background in fintech, payments, banking or other regulated industries, including card and payment infrastructure supporting rails such as Faster Payments, SEPA, SWIFT and ACH.
• Experience with high-volume transaction platforms, event-driven architectures and API platforms.

The technical environment spans AWS, Azure or GCP, Kubernetes or ECS, Terraform, GitHub Actions or similar CI tools, Linux, MySQL/MariaDB/PostgreSQL, Python or Bash, and Prometheus/Grafana-style monitoring.

This could suit a senior platform engineer from a payments or regulated fintech background who wants real ownership of a cloud platform and a team that has committed to AI-assisted engineering.

The employer cannot provide visa sponsorship; you'll need eligibility to work in the United Kingdom.
