A senior leader at one of the firms I work with said something recently that stuck with me: "The median researcher adds zero value." He wasn't being provocative for the sake of it, if you think about it. Most quant researchers at most firms are working on the same low-hanging fruit, on overlapping research, competing internally for the same capacity, hedged into irrelevance by a risk framework designed to protect the platform from them rather than empower them. He went on to describe the kind of person he actually wants to hire, and it was pretty specific: Someone who finds genuine satisfaction in the work itself. Not the comp table (appreciating that no-one works for free, right!), not the brand... Quant researchers who read JVM optimisation papers because they want to understand why their backtest is slow, not just that it's slow. Developers who dig into market microstructure literature because they want to understand what their execution code is actually doing, not just that it works. The kind of person whose curiosity bleeds across disciplines; researchers who think like engineers, engineers who think like traders, because they've figured out that the interesting problems live at the boundaries, not inside the silos. Someone with enough intellectual disagreeableness to challenge assumptions in a room full of people, because they care more about being right than being liked. And critically, someone who has actually delivered something, personally, not just improved or maintained what was already there. If that sounds like something you have thought about, and perhaps at some level agree with, maybe we should chat. The project is this: a proprietary systematic shop with hubs in London and NYC, and satellite locations in Europe and US. What they trade: Futures and Equities. Short-term holding periods, at the higher end of the mid-freq spectrum (or the slower end of the high-frequency spectrum, however you prefer to think of it). Exceptional research and execution infrastructure. Significant investment in GPU infra to enhance ML/AI-driven research. Experience delivering strategies at Sharpe ~2-3+ is the qualifier. If you're currently running strategies at that frequency and wondering why your infrastructure costs eat half your contribution, or why 23 other teams at your firm are crowding the same positions, and think that you'd genuinely be interested in being somewhere that you could add direct value to the top-line within an environment that is demonstrably meritocratic (I have numerous examples of this playing out historically within the firm), it'd be worth getting in touch to find out more. What they don't want: someone optimising for their next move. Someone whose first question is "what's the guarantee?" (we'll chat about it, but if it's the primary motivator, that's probably a self-selector...). Someone who views collaboration as a vulnerability rather than an edge. This firm isn't entirely unique, but it's clear on its strategy. I'm also working with a small number of firms that operate this way. London or NYC as primary hubs, fully remote optionality on the table potentially. If this sounds like the kind of environment where you'd do your best work, we should definitely chat.

The work This is a systematic quant researcher role within a cross-asset trading environment spanning holding periods from intraday (mins/hours) to weeks. You will own the full research pipeline: signal generation, testing, portfolio-level analysis, and work with live capital. The asset universe is broad: equities, futures, FX, credit, commodities, and ETF structures all feature. The problems are genuinely hard: signal decay, regime sensitivity, execution friction, and cross-asset correlation structure all matter here. You will be expected to form views, test them rigorously, and defend them. The infrastructure You will have access to data and compute infrastructure at a scale very few firms can match. Research custom trading models to compete with the scale of frontier LLMs, consuming trillions of tokens of market data. Experimentation here is not constrained by tooling, it is constrained by the quality of your ideas. How the team operates Research here is a shared endeavour, not a collection of siloed books. Every researcher has full visibility into every active strategy's code. There are no black boxes, no protected territories. The expectation is that collective understanding produces better research than individual ownership. Strategies are sized for their contribution to the portfolio as a whole, not as standalone entities. That means your work is evaluated at the system level, which rewards researchers who think carefully about covariance, capacity, and cross-strategy interaction, not just isolated backtest Sharpe. What we're looking for You have 3-10 years of experience in a systematic trading environment, a hedge fund, prop trading firm, or closely related research role. You have built and shipped predictive models against real market data, not just in simulation. You have a rigorous research methodology, and are driven by data and intuition to come up with novel ideas, and augment existing ones. Core requirements: • Strong statistical foundations: time-series analysis, factor modelling, signal research, • Python proficiency; C++ experience strongly preferred (you will be interacting with C++ day to day), • Experience across more than one asset class, or a clear track record in one with genuine appetite to work cross-asset, • Ability to take a research idea from hypothesis to backtested strategy to production-ready code, • Comfort operating in an environment where your work is visible and subject to peer scrutiny The right mindset: You are intellectually honest about what your models do and don't explain. You are more interested in understanding market structure than in protecting alpha. You find the idea of a shared codebase appealing rather than threatening. Where? London is a focus area, but realistically anywhere across the major financial hubs (NYC, Singapore, Hong Kong, Chicago).

AI performance is the major tech theme for the next decade. We are building systems that autonomously discover, test, and ship state-of-the-art GPU kernels. Our mission is to fully automate this process by combining LLMs with evolutionary methods. We just closed an unannounced $4.2M pre-seed round from top-tier funds and technical angels, and have proven results with large and sophisticated enterprise partners on custom neural architectures We believe that revolutionary breakthroughs often happen at the intersections of fields. We are not a research lab, nor are we an AI agents company. We’re working at the intersection of LLMs and evolutionary computing to build self-improving systems. We’re looking for exceptionally talented engineers and researchers to join us on this epic quest Responsibilities • Write SOTA GPU kernels, • Own complex production ML/AI systems end-to-end, • Understand how kernel-level gains translate to wall-clock improvements in production., • Build the infrastructure that lets LLM agents iterate unsupervised for days - compilation, correctness, benchmarking, scoring, lineage tracking..., • Design the evolutionary search - fitness landscapes, variation operators, population management, selection pressure, stagnation detection, exploration vs. exploitation over multi-day autonomous runs, • Communicate and share ideas through high-quality documentation, technical meet-ups and blogs For lead candidates: Hire and mentor a small team of exceptional engineers and researchers Qualifications • You've written and shipped high-performance or SOTA CUDA kernels, • Deep understanding of mixed precision, quantisation (INT4, INT8, FP8, MXFP4, block-scaled formats), kernel fusion, distributed computing strategies (TP, PP, CP), • You've made deliberate choices about tiling, memory access patterns, warp-level primitives, and instruction scheduling, • You've traced performance cliffs to their root cause through profiler output, • You've worked with CuTe, Triton, Helion or equivalent abstractions, and know when to dive into PTX, • You understand GPU architecture across generations — registers through L2, warp execution, divergence costs, occupancy tradeoffs, what changed between Hopper and Blackwell and why it matters, • You know transformers at the implementation level. Attention variants, KV cache strategies, quantisation schemes, and how they shape kernel design, • You've worked with production inference or training frameworks, vLLM, Megatron-LM, etc., • You've built performance-critical infrastructure before - compilers, profilers, auto-tuners, or search systems, • You have real intuition for evolutionary methods, fitness landscapes, and what makes variation operators work on hard combinatorial problems, • You're familiar with new or esoteric technical methods such as Neural Algorithmic Reasoning, Geometric Deep Learning, Category Theory, Neuroevolution, Megakernels, or the work of François Chollet, Kenneth Stanley, Jeff Clune, Jurgen Schmidhuber, David Ha, and Christian Szegedy Bonus • Open-source kernel contributions (FlashAttention, FlashInfer, vLLM, Unsloth, Liger-Kernels, ThunderKittens), • Publications in ML/AI, kernel optimisation or evolutionary methods (NeurIPS, ICLR, CVPR, GECCO or equivalent), • Other HW experience (AMD, MLX, edge HW), • Familiarity with TileLang, Helion, CuTile, • Experience building agentic systems, • Demonstrated work on KernelBench, Kaggle, GitHub, Blogs, StackOverflow Answers, or any public work that demonstrates deep EA, ML or GPU/HW expertise, • HPC experience This is a full-time, permanent role. Competitive salary + significant founding equity.
