DevOps Engineer

This is a hybrid role that requires 3 days/week in our London (Fitzrovia) office

The structural conflict at the centre of correspondent banking is not technological. It is economic. Banks earn revenue from their balance sheets: they lend deposits, capture FX spreads, and hold funds as long as it is rational to do so. Clearing, the act of releasing funds quickly and predictably, competes directly with those economics. An institution designed to lend has a structural incentive to hold deposits;

an institution designed to clear has an incentive to release them. When one institution does both, clearing loses. The result is unpredictable settlement, trapped capital, and a correspondent network shrinking by design.

Lorum was founded on a different premise: clearing as the business, not a byproduct. The model has been operational since 2023 and grew 55x in 2025, with USD clearing now the majority of volumes alongside a growing treasury offering. We have applied for a U.S. national trust bank charter. The people we hire now will build the clearing and treasury infrastructure it unlocks.

We are looking for a Senior Dev Ops Engineer to join our engineering team in London. You will own and improve the cloud infrastructure, CI/CD and observability that our clearing platform runs on, working directly with backend engineers and Security. As volumes grow and regulatory expectations rise, you will make production safer, more observable and easier to recover, and you will be trusted to form opinions and act on them.

• Design, build and maintain AWS infrastructure as code with Terraform, including state management and Git-driven workflows (Atlantis or equivalent) for safe, auditable changes
• Build and run Git Hub Actions pipelines for build, test, release and infrastructure deployment, with fast pre-merge checks and reliable environments for engineers
• Run production services: on-call, incident response, post-mortems and capacity planning, with a focus on resilience and failover
• Instrument our systems with metrics, logs and traces, and use that telemetry to drive reliability improvements
• Work with Security and GRC on SOC 2 / ISO 27001 requirements: secure deployments, secrets management, IAM, and encryption at rest and in transit
• Automate repetitive operational work, build self-service tooling and runbooks for developers, review infrastructure changes and help raise engineering standards

• Within your first weeks, ship a concrete improvement to our infrastructure or pipelines
• By month 3, be working autonomously across AWS, Terraform and Git Hub Actions and have taken ownership of the tools that support them
• By month 6, have led improvements to resilience and failover for core production services, with clear runbooks and tested recovery paths
• By month 12, have traces and logs aggregated in a central observability stack that engineers use day to day, and be a trusted voice on infrastructure decisions and compliance priorities

• Extensive experience operating production cloud infrastructure on AWS
• Strong Terraform: writing modules, managing state and work spaces
• Practical experience with Atlantis or an equivalent for Git-driven Terraform automation
• Hands-on experience building CI/CD pipelines with Git Hub Actions or Workflows
• Solid Linux, networking and container fundamentals (Docker), with Kubernetes or ECS experience
• A strong testing and automation mindset: infrastructure tests, integration tests and pre-deploy checks
• Experience with observability stacks (Prometheus/Grafana, Datadog, ELK or similar)
• Security and compliance awareness: IAM, VPC, KMS and secrets management
• A clear communicator who is comfortable driving cross-functional operational work and incidents
• Able to work hybrid, 3 days/week in our London office

• Experience in fintech, payments or other regulated, high-availability environments
• PostgreSQL operations, stream processing or event-driven architectures
• Policy-as-code (OPA, Sentinel) and infrastructure-as-code security scanning
• Terraform Cloud/Enterprise, Terragrunt or similar
• SRE or platform engineering experience, including developer self-service tooling

• Comfortable having opinions and taking responsibility; you challenge ideas constructively, including from engineers and leadership
• Autonomous and comfortable with ambiguity: you are happy building something from scratch…
