SRE/Infra | Quant Trading

Senior SRE / Platform Engineer | Elite Quant Hedge Fund | London

Paragon Alpha is partnering with a leading ~$70BN AUM quantitative trading firm following an exceptional 2025 and continuing to invest aggressively across its global technology organisation.

As the business scales, they're expanding a world-class Infrastructure / Site Reliability Engineering function responsible for the reliability, performance, and scalability of the technology powering systematic trading. In this environment, availability, correctness, and latency aren't just engineering metrics – they're a competitive advantage.

This is a genuinely high-impact engineering role sitting at the intersection of SRE, Platform Engineering, and Software Engineering , where you'll build the tooling and infrastructure that enables researchers and traders to operate at scale.

You'll work across:

• Kubernetes and large-scale distributed platforms
• Observability (metrics, logging, tracing, alerting)
• Backend platform services and internal developer tooling
• Python engineering, with Go and TypeScript across parts of the stack
• Linux systems, networking, automation, and release engineering
• Reliability, scalability, and reducing operational toil through engineering

You'll join a team that values technical excellence, ownership, and automation-first thinking , solving complex infrastructure challenges that directly influence trading performance.

We're operating with a blank cheque for exceptional engineers. If you're one of the strongest SRE, Platform, or Infrastructure Engineers in the market and enjoy building systems at the highest level, I'd love to speak with you.
