Pros

- High ownership environment. The culture is big on making impact and getting stuff done. - Very smart coworkers who are also friendly, happy to collaborate, and low-ego. - Lots of opportunities to work on genuinely interesting and fairly cutting-edge modeling and research problems - The firm has made huge improvements to core infrastructure. This includes all sorts of stuff like compute, storage speed, data availability, platform robustness, etc. - The firm being smaller means good ideas can move quickly and individuals can shape the direction of research.

Cons

- Parts of the core C++ platform still contain old clunky legacy code, and although there has been a lot of cleanup work, there is still a long way to go. - Because the firm is relatively small, some quality-of-life tools and "nice to have" internal systems are missing compared to larger shops. - As a researcher, you often need to spend some time on the research pipeline and development work rather than purely on modeling or idea generation.

Pros

The technical challenges are really top-tier. Low-latency HFT work is unlike anything else in software engineering. You're constantly thinking about performance, down to the hardware. Great place if you're into systems programming and C++. The engineering team is strong and there's real autonomy over technical decisions. You have a say in architecture and tooling, not just implementing what someone else decided. Small team means you touch many parts of the system instead of being stuck in one corner.

Cons

There's noticeable legacy technical debt. Some parts of the codebase grew organically over the years without consistent standards, so refactoring always competes with feature work. This is improving, but it's an ongoing challenge The team could use more people. Individual scope is wider than what you'd expect at a bigger HFT company, and it shows when someone is out or during busy periods. A few more hires would make a real difference in workload balance. On the bright side, there's no shortage of interesting work to do.
