• Strong proficiency across Python/TypeScript/Golang (or equivalent polyglot stacks) with proven ownership of production-grade systems.
• Expertise in real-time systems, performance optimisation, fault tolerance and scalable architectures under uncertainty.
• Experience with financial protocols, market data feeds, order matching or compute infrastructure is a strong plus.
