Principal Devops Engineer

Principal Dev Ops Engineer (Senior Individual Contributor)
Fin Tech | Reports to VP Dev Ops

Our Fin Tech client is looking for a Principal Dev Ops Engineer to play a pivotal role in shaping how their engineering teams build, deploy and operate software at scale.

This is the most senior individual contributor within Dev Ops, no direct reports, but organisation-wide influence. You'll design and evolve the engineering delivery platform, driving improvements to CI/CD, developer experience, and platform reliability across cloud and on-prem environments.

A key initiative is an active migration from Azure Dev Ops to Git Hub Enterprise & Git Hub Actions, so experience delivering similar platform transitions is essential.

• Lead the design and evolution of the enterprise CI/CD platform across cloud and on-prem infrastructure
• Own and deliver the migration to Git Hub Enterprise & Git Hub Actions, building reusable workflows and quality gates
• Define platform standards across Terraform, Ansible, Vault, Docker and artifact management
• Improve engineering delivery through automation, inner-source tooling and self-service developer platforms
• Track and optimise Dev Ops delivery metrics (deployment frequency, lead time, change failure rate, MTTR)
• Work across engineering teams to identify systemic problems and implement scalable solutions

• Extensive Dev Ops / platform engineering experience with strong software engineering foundations
• Proven track record leading large-scale platform or CI/CD transformations
• Hands-on experience with Git Hub Enterprise & Git Hub Actions migrations
• Ability to write production-quality code in C# or Java
• Experience improving engineering performance using DORA metrics

• Git Hub Enterprise & Git Hub Actions
• Terraform (module authoring)
• Ansible (roles / collections development)
• Hashi Corp Vault
• Docker & Docker Compose
• Cloud platforms: AWS, Azure or GCP
• On-prem Linux environments

Nice to have: Cloudflare, Cloudsmith, Splunk, SAST/DAST tooling, Maven/Gradle, .NET CLI.

• Experience leading organisation-wide Dev Ops platform changes with measurable outcomes
• Comfortable operating across polyglot environments (.NET & Java)
• Strong advocate for inner-source, developer self-service and platform automation
• Able to produce clear architecture documentation, RFCs and technical design decisions

This role would suit a staff/principal level engineer who enjoys solving systemic engineering problems, designing scalable platforms and influencing how entire engineering organisations deliver software.
