About The Role
We’re building a modern Platform Engineering team focused on creating self-service, scalable platforms that empower developers and accelerate delivery. This isn’t about “doing DevOps” for others; it’s about engineering resilient systems, improving developer experience, and enabling teams through automation and architecture.

As a Senior Platform Engineer, you’ll lead the design, implementation, and evolution of complex infrastructure projects that power our engineering teams and products. You’ll drive large-scale initiatives independently, mentor others, and shape the future of our platform strategy. Success isn’t measured by uptime alone; it’s about adoption, developer satisfaction, and reducing cognitive load.

• Architect and lead complex platform projects from design to deployment.
• Enable engineering teams with robust CI/CD capabilities through reusable patterns, automation, and security-first practices.
• Design scalable infrastructure using Infrastructure as Code and config management tools.
• Build and optimize cloud-native architectures across multiple cloud providers with cost efficiency in mind.

• Champion security and compliance across infrastructure and delivery pipelines.
• Architect secure, scalable networking solutions for hybrid and cloud environments.
• Drive continuous improvement through automation, scripting, and tooling.
• Lead and mentor engineers, foster collaboration, and influence technical direction.
• Troubleshoot complex issues, optimize performance, and plan for capacity at scale.

Skills, Knowledge and Expertise

• Deep expertise in CI/CD, automation, and pipeline architecture.
• Mastery of IaC tools (e.g., Terraform, Pulumi) and config management (e.g., Ansible, Chef).
• Strong AWS architecture skills and cost optimisation strategies
• Advanced containerization and orchestration experience (Docker, Kubernetes, etc.).
• Proficiency in observability tools (Prometheus, Grafana, ELK, OpenTelemetry).
• Security-first mindset with hands-on experience in access control, encryption, and incident response.
• Solid networking knowledge - protocols, routing, firewalls, and cloud networking.
• Experience integrating and optimizing software delivery ecosystems (Git, Artifactory, Jenkins) as part of a cohesive platform strategy.
• Strong scripting and automation skills (Python, Bash, Go, etc.).
• Proven leadership, mentoring, and stakeholder communication skills.
• A knack for solving hard problems and making systems better.
• You’ll help shape the future of our infrastructure and the team itself.

We offer a rewarding and challenging place to work, a transparent and collaborative culture and a well rounded benefits package. Below are some of what we currently offer:

• Participation in our industry leading share options scheme
• Private Medical Plan
