We are looking for an exceptional Senior Platform Engineer to join a highly technical, engineering-driven team building and running the core infrastructure that powers a complex, mission-critical trading environment. This is a rare opportunity to own infrastructure end-to-end, work with a modern cloud-native stack, and shape a platform that is engineered with quality, automation, and reliability at its core.
Base pay range: £65,000.00 - £90,000.00 (London, United Kingdom)
What You’ll Work On
* Infrastructure as Code & Automation
o Designing and building infrastructure using Terraform, Helm, Ansible, and Puppet
o Implementing fully automated, GitOps‑style provisioning and lifecycle management
o Codifying repeatable patterns for platform reliability, security, and scaling
* Containerisation & Orchestration
o Operating and improving large‑scale containerised workloads
o Working with Nomad (preferred) or Kubernetes (fully transferable)
o Understanding and implementing CNI and CSI patterns for networking and storage
* Core Systems Engineering
o Building secure, robust, self‑service platform capabilities for engineering teams
o Implementing secrets, identity, and policy through HashiCorp Vault
* End‑to‑End Ownership
o Working autonomously to solve difficult problems across the full platform layer
o Designing, standing up, and running services in a Linux‑native environment
o Working closely with senior technologists across the business
What We’re Looking For
* True Seniority. A platform engineer with breadth as well as depth—not someone who has spent their career in a silo.
* Linux‑first mindset. You live and breathe Linux systems and understand how distributed workloads behave underneath.
* Modern container & IaC expertise. Strong experience with Nomad/K8s, Terraform, Helm, Ansible/Puppet, Vault, and cloud‑native tooling.
* Breadth of exposure from a smaller environment. Ideally someone from a small, high‑impact engineering team, a startup with real ownership, or a consultancy/vendor environment with wide hands‑on exposure.
* Stability and craft. A track record of delivering quality over time—not a job hopper.
What We Offer
* A senior, engineering‑led culture with extremely high technical standards
* The autonomy to design and operate infrastructure the right way
* A role where your impact is visible, meaningful, and valued
* A modern platform built on cloud‑native principles, not legacy firefighting
* Competitive compensation for top‑tier talent
* An environment that rewards curiosity, ownership, and technical excellence
Who This Role Is Perfect For
* Wants to own infrastructure rather than sit in a large silo
* Enjoys solving deep technical problems across the full stack
* Likes working alongside other high‑calibre senior engineers
* Thrives in an environment with accountability, modern tooling, and genuine complexity
* Wants to see the impact of their work immediately
