MF Equity ML Researcher | Prop Trading Firm | West Coast US

Researchers at big quant firms are (for the most part) interchangeable. Deep down, the good ones know it...You can feel it... Your ideas get abstracted into "the stack" and become un-owned. Your risk framework is built to protect the platform from you rather than empower you. You're one of forty researchers competing for roughly the same positions internally, and if you stick around another five years, you'll be one of thirty-five, slightly more senior, marginally better paid, and still fundamentally a cog. In a world where the research layer is quietly becoming the only place alpha actually lives, that sounds like a structurally bad seat.The good news: this isn't the only quant job that exists. The bad news: the genuinely different ones are rare, and they don't stay open long. I'm working on one of them.The setup: a HFT prop firm, building an ML-driven mid-frequency (mins>hours) equities team from scratch on the US West Coast (LA). Central team, firm-level commitment, not a pod, not a multi-manager. The team lead came out of one of the best HFT firms in the business, where he spent the last few years on the shift that's quietly reshaping this industry: "slower and smarter" rather than "faster and faster." The pure-speed frontier isn't where the edge lives anymore. The real edge has migrated into the signals and the models, and the firms who figured this out early are structurally ahead.The hire(s) they're looking to make are "T-shaped":- Deep specialty in one of: modern ML architecture (Stanford-PhD-levels-of-depth across the literature, not "I ran XGBoost once"), MFT alpha research (order-book imbalance, signal decay, actual trading-aware intuition), or portfolio construction. Plus enough breadth in the other two to hold your own in the room. In a small team, there's no room for pure specialists.Startup ethos. If your instinct when you need a piece of code is "I'll wait for someone to build it," this isn't the seat. If it's "I'll just build it myself this week, then test my idea," it probably is.Demonstrable ship history. A strategy that went from your head to live PnL, not something you maintained, improved, or co-owned with four other people.People who probably aren't in the sweet spot:Narrow trade-experts. Five years on one strategy with the rest of the stack handled by someone else doesn't transfer to a team this small.Comp-first candidates. Package is competitive, but if your first question is what the guarantee looks like, you're probably optimising for the wrong thing. First movers on something like this get outsized upside if it works.Location: US West Coast (LA). There aren't many teams in the world right now who can credibly offer "MFT ML research built on a world-class HFT execution stack" as the proposition. Even less that can offer that as part of a genuine start-up business within an already successful, capital unconstrained prop firm expanding into new markets and at the start of a very ambitious, very achievable growth story. If you're five-ish years into a big-firm seat and find yourself more resentful than energised by the size around you, it's probably worth a conversation.ben@augmentti.com
