As an Operations Engineer, you will ensure the stability, performance, and availability of the Reactive trading platform. This is a hands-on, technical operations role — focused on production systems, infrastructure, and trading workflows rather than client relationship management.
You’ll work closely with Engineering, Product, and internal stakeholders as the first line of defence for live trading systems. TechOps owns Level 1 and Level 2 support — monitoring response and alert triage through to the deeper technical investigation, configuration delivery, and post-release verification that sits beneath it — escalating to Level 3 (Engineering and Infrastructure) only when an issue genuinely requires code changes or deep infrastructure intervention. While the role involves supporting client onboarding and integrations, the emphasis is on technical delivery, system correctness, and incident response — not sales or account management.
Reactive runs a globally distributed, follow-the-sun operations team, and we are hiring across our UK, US, and Singapore hubs. You’ll provide operational coverage across your regional trading session — the eyes on the platform when your region is live — and hand over cleanly to the next hub as the day moves. In each region you own the full TechOps remit: monitoring and incident response through the session, plus the configuration delivery, onboarding execution, and change work that keeps the platform growing. The UK and US roles are remote; the Singapore role is office-based.
We are a small team that has turned operations into a genuine engineering discipline, and we are investing heavily in AI-assisted tooling and knowledge engineering to keep it that way. This role suits someone with experience in trading or FinTech operations who enjoys working close to production systems, solving complex problems, writing things down properly, and taking ownership in a fast-moving environment.
