Platform Engineer

Platform Engineer – Low-Latency Trading (Linux/Kubernetes)

Fully Remote | Contract Outisde IR35 or Perm | Greenfield Prediction Markets Exchange

What does it take to build the infrastructure behind a high-performance trading exchange from scratch?

We're helping build an ambitious new prediction markets exchange, backed by eight figures of private investment, with launch planned for early 2027.

We're looking for a Platform Engineer who understands Linux, networking and performance engineering at a deep technical level.

This isn't a typical DevOps role.

You'll help design and operate the infrastructure supporting a new exchange, matching engine, real-time market data and automated trading systems.

You'll work alongside experienced low-latency engineers in a small, highly technical team, with significant ownership of architecture and infrastructure decisions.

What You'll Be Building

• Low-Latency Linux Infrastructure: Optimising CPU isolation, core pinning, IRQ affinity, NUMA and kernel behaviour for predictable performance.
• High-Performance Networking: Tuning TCP/UDP, NICs, multicast and network configurations to minimise latency, packet loss and jitter.
• Kubernetes & Platform Engineering: Building and operating production clusters, deployments and GitOps-based infrastructure.
• Infrastructure Automation: Designing reproducible environments using Terraform, Ansible and scripting.
• Production Reliability: Building monitoring, investigating performance bottlenecks and ensuring resilient, secure trading infrastructure.

What We're Looking For

• 5+ years in Linux infrastructure, Platform Engineering, SRE or a similarly hands-on role.
• Strong production Linux and Kubernetes experience.
• Practical knowledge of Linux performance tuning, CPU scheduling, networking and system-level diagnostics.
• Strong TCP/UDP networking fundamentals and experience investigating latency, packet loss or infrastructure bottlenecks.
• Experience with infrastructure automation, observability and production incident management.

Especially interesting: Engineers from HFT, electronic trading, exchanges, HPC or other performance-critical environments.

Experience with bare metal, colocation, DPDK, eBPF, PTP, Aeron, Prometheus, Grafana or advanced Linux kernel tuning would be a significant advantage.

Why This Is Different

• Fully remote contract or perm opportunity.
• Eight-figure private investment backing.
• Genuine greenfield infrastructure and architectural ownership.
• Work directly with engineers building high-performance trading systems.
• Shape the infrastructure behind a new exchange before its 2027 launch.

We're not looking for someone who simply deploys applications to Kubernetes. We're looking for someone who understands how Linux, hardware and networks behave when performance really matters.

If that sounds like your kind of engineering challenge, I'd be keen to hear from you.
