Senior/Staff SRE

UFORCE, United Kingdom - London

The role

UFORCE is looking for a Senior Site Reliability Engineer to help build and operate the cloud infrastructure platform behind our sovereign mission operations teams. You’ll make it safer and easier to deploy, upgrade, and run UFORCE services in on-premises environments, including sites with limited or no internet connectivity.

You’ll combine hands-on infrastructure engineering with practical operational ownership: automating deployments, strengthening reliability, and making sure customer IT and partner operations teams can run the platform with confidence. You’ll work closely with Platform Engineering, Security, and customer-facing teams, with a focus on solutions that are secure, supportable, and usable in the field.

Wait…

What you’ll do

Build and improve deployment and maintenance automation for on-premises environments, including infrastructure as code, packaging, environment validation, and preflight checks.
Make releases and upgrades work reliably in offline or restricted-network settings: manage artifacts and versioning, define validation gates, and document staged rollout and rollback procedures.
Develop repeatable deployment patterns for VM-based, Kubernetes-based, and mixed environments, and document when and how to handle deviations.
Establish and maintain an observability baseline for constrained environments, including useful metrics, logs, alerts, and dashboards. Make alerts actionable and link them to clear runbooks.
Define and operationalize service-level objectives and change-safety practices such as smoke tests, rollout checks, and rollback-first procedures.
Respond to incidents across deployed environments, coordinate diagnosis and communication, and turn lessons learned into improvements to automation, monitoring, and operations.
Create and maintain operational playbooks, troubleshooting guides, escalation paths, and maintenance workflows for customer IT and partner operations teams.
Partner with engineering and security teams to identify operational risks early and ensure new platform capabilities are ready to deploy and support.
Coach teammates on practical reliability habits, including debugging, alert quality, incident follow-through, and documentation.

What success looks like

Standard environment setup and refresh becomes faster and more repeatable, with a path to completing common footprints in less than a day.
Upgrade and rollback procedures are validated, well documented, and executable by partner operations teams with limited SRE support.
New deployments have usable dashboards and actionable alerts quickly, supported by reusable configuration and runbooks.
Customer and partner operations teams resolve more routine issues independently, while recurring incidents lead to durable engineering improvements.

The nature of combat has changed.

Tomorrow’s battlefield success depends on autonomy, speed, and adaptability.

And UFORCE is ready.
