Jobs in Gresham, United Kingdom

About the role

We're hiring a Principal Platform Engineer to be a senior technical anchor in our Platform/Operations function. This is a 70% hands-on engineering role: you'll design, build, and operate the infrastructure that keeps a global trading platform running, while acting as a technical mentor and design authority across the wider team.

What you'll bring

• A background in Operations or SRE running highly available, redundant production platforms — you understand failure domains, graceful degradation, and what "five nines" costs
• Deep hands-on experience with AWS (VPC design, networking, EKS) and Azure (AKS, Key Vault, networking) — genuinely multi-cloud, not one cloud plus a certification
• Strong Networking fundamentals: TCP/IP, routing concepts, firewalls, load balancing, hybrid connectivity (Direct Connect / ExpressRoute, VPNs)
• Production Kubernetes experience at scale, including day-2 operations (upgrades, capacity, security, multi-cluster)
• Infrastructure-as-code and automation as a default working style (Terraform, Ansible, or similar
• strong scripting in Python, Go, or Bash)
• Demonstrable, practical use of AI tooling to improve engineering or operational workflows — you can show us something you've automated, accelerated, or de-toiled with it
• The credibility and communication skills to mentor senior engineers and influence design decisions without formal authority
• Understanding of different database technologies
• Experience in trading, exchanges, market data, fintech, or another latency- and availability-sensitive domain
• Trayport is committed to creating and sustaining a collegial work environment in which all individuals are treated with dignity and respect and one which reflects the diversity of the community in which we operate.
• We provide accommodations for applicants and employees who require it.
