Job Description:

Senior Lead Java Developer (Equity Derivatives Platform)

You'll build and optimize a low‑latency risk & pricing platform for flow volatility products – working side‑by‑side with traders, quants, and sales.

  • Own end‑to‑end delivery of a high‑performance pricing and risk system – from multithreaded Java code and unit tests to production support
  • Partner closely with traders and quants to implement auto delta hedging, vega roll strategies, and real‑time trade capture
  • Apply deep equity derivatives knowledge (pricing, risk, order management) to build volatility fitting, visualization, and pre/post‑trade analytics
  • Work with Linux, distributed messaging (Solace, ZeroMQ, or similar), and low‑latency techniques – live ticking data and regulatory reporting
  • Zero‑garbage‑collection experience is a strong plus, as is a background in high‑frequency or low‑latency trading systems

What you bring:

  • Advanced Core Java with multithreading expertise
  • 6+ years of hands‑on development (VP level)
  • Solid understanding of equity derivatives and trading workflows
  • Fluent English – Cantonese/Mandarin a plus

What's on offer:

  • Competitive base + discretionary bonus
  • Work with a global, collaborative team in Hong Kong
  • Relocation support and visa sponsorship available for strong candidates
