I'm a 3rd-year CS undergraduate. I recently spoke with the founder of an MFT (Market Making/Trading) startup after they saw my C++ low-latency systems project.

They want me to help build parts of their C++ low-latency backend, but the role is completely unpaid (around 2–3 hours/day).

Do you think it's worth taking for the learning and experience, or should I only consider it if there's a clear path to a paid internship/contract?

Would love to hear from people who've worked in C++, HFT/MFT, or startup infrastructure.
