About Mako
Mako is a leading options market maker with a global trading footprint. It has been at the forefront of options market making since 1999, from the open outcry trading pits to screen trading and automated algorithmic execution strategies that are driving the future of the industry.
What you’ll be involved in
- Design, build and ship parts of our trading stack — exchange connectivity, order state management, low-latency execution, boundary risk checks — and keep them running in production.
- Profile and improve latency and throughput on the hot path; reason about cache, allocations, contention and the network stack, and measure rather than guess.
- Work directly with traders and researchers to identify improvements to our execution performance and turn trading ideas into real production impact.
- Diagnose live issues during market hours and drive them to root cause.
- Raise the quality of the codebase through rigorous review, sensible testing and clear written design.
- Coach and mentor other engineers — pairing, reviewing in depth, and helping them grow.
What we need from you
- At least 5 years of hands-on C++ development on a latency-sensitive or high-throughput system running on Linux, with experience developing trading systems at a prop shop, market maker, hedge fund or similar.
- Good understanding of exchange connectivity protocols (e.g. FIX, ITCH/OUCH, proprietary binary) and the mechanics of limit order books.
