About the Role

We are seeking a Mid-Level C++ Software Engineer to join our elite high-frequency trading firm, Mondrian Alpha. This Mid-Level C++ Software Engineer remote position offers a unique opportunity to work on ultra-low latency market making systems that directly impact trading performance. You will be part of a team that values measurement, rigor, and craft, and you will have the chance to earn up to $1.5 million in total compensation in your first year.

What You'll Do

  • Build and optimize multi-threaded C++ components for market data, order entry, and execution.
  • Own performance work end-to-end: profiling, debugging, instrumentation, and proof of performance improvements.
  • Scale core systems across venues and regions while protecting latency, determinism, and correctness.
  • Work in tight feedback loops with traders, quants, and systems peers to ship improvements quickly and safely.
  • Engage in low-level Linux tuning, including CPU pinning, NUMA awareness, and kernel/network tuning.

Requirements

  • Expertise in C++ within performance-critical environments, focusing on hot paths, allocation, contention, and tail latency.
  • Strong fundamentals in concurrency, low-latency design, and CPU/memory behavior.
  • Solid Linux/Unix skills, comfortable with performance tooling and system-level debugging.
  • A high ownership mindset: you ship, measure, and iterate on your work.

Nice to Have

  • Experience in high-frequency trading or market connectivity (feed handlers, gateways, exchange protocols).
  • Familiarity with FIX/OUCH/ITCH or similar protocols.
  • Experience with deterministic capture/replay, simulation frameworks, or research-to-production integration.

What We Offer

  • Relocation support for candidates willing to move to New York.
  • A top-of-market upside: top performers can earn up to $1.5 million total compensation in their first year.
  • A collaborative engineering culture where engineers contribute to architecture strategy and design.
  • Regular leadership touchpoints to influence direction-setting on architecture and strategy.
  • Opportunities for professional growth and development in a fast-paced environment.
