  • Industry experience in electronic FX market making, prop trading, or e-FX technology (5+ years)
  • Master's or PhD in mathematics, statistics, physics, CS, financial engineering, or similar
• Tentative Responsibilities/Projects
  • Algorithmic pricing models: fair value estimation, skew, spread optimization, toxicity scoring
  • Hedging and inventory management: portfolio optimization, delta VaR, alpha adjusted target positioning, algorithmic execution
  • Smart order routing: venue selection, liquidity displacement detection, optimal execution
  • Market impact models: adverse selection, fill probability, client flow classification for SI
  • Backtesting and simulation

Core Engineering

• Desired Skills
  • C++ on the hot path — cache-line discipline, memory layout, lock-free data structures
  • Kernel bypass networking (Solarflare OpenOnload / DPDK) and binary protocol development
  • Linux systems programming: CPU isolation, NUMA, huge pages, IRQ affinity, kernel tuning
  • FIX protocol, Itch and exchange connectivity (ideally FX: EBS, Cboe FX, LMAX, Fastmatch, or similar)
  • Experience building or operating in electronic market making, prop trading, or exchange infrastructure
• Tentative Responsibilities/Projects
  • Lock-free order books, level books, matching engine internals, and zero-allocation execution paths
  • Integration with messaging infrastructure (shared memory IPC, topic-based pub/sub)
  • Exchange connectivity: FIX session management, ITCH feed handlers, binary protocol codecs
  • Real-time risk and position management across 30+ pairs and multiple venues

If you’re passionate about applying advanced technology to real-world markets and want to work alongside a focused, high-performing team, we’d love to hear from you. DeepFin offers a collaborative, research-driven environment where ideas move quickly from concept to execution and where every contribution has visible impact.
