DevOps Engineer

Location: London or New York - in office 4 days a week About Lorum 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.

Why Lorum 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.

Role purpose Build, operate and improve the cloud infrastructure and CI/CD systems that power Lorum’s clearing platform. Partner with backend, security, and product teams to deliver secure, observable, and reliable production services with strong automation and ownership.

Key Responsibilities

• Operate and maintain Atlantis or other Git-driven Terraform automation for safe, auditable infra changes.

• CI/CD & developer workflows

• Build and maintain GitHub Workflows / Actions pipelines for build, test, release and infra deployments.

• Improve developer DX: fast, reliable pipelines, automated testing, pre-merge checks, and environment provisioning.

• Reliability, observability & operations

• Run production services: participate in on-call, incident response, postmortems and capacity planning.

• Instrument systems (metrics, logs, tracing) and use telemetry to drive reliability improvements.

• Security & compliance

• Work with Security and GRC to meet SOC 2 / ISO 27001 and similar requirements: secure deployments, secrets management, IAM policies, and encryption at rest/in transit.

• Automation & tooling

• Automate repetitive operational tasks, build self-service platforms for developers, and contribute internal tooling and runbooks.

• Collaboration & delivery

• Partner with backend engineers (see pages 1–3 for team expectations) to define deployment boundaries, APIs, and operational responsibilities.

• Review infra changes, mentor peers, and help maintain high engineering standards.
