Location: San Francisco Workplace: Hybrid WHY HARVEY At Harvey, we’re transforming how legal and professional services operate. By combining frontier agentic AI, an enterprise-grade platform, and deep domain expertise, we’re reshaping how critical knowledge work gets done for decades to come. This is a rare chance to help build a generational company at a true inflection point. We have strong product-market fit and world-class investor support. We’re scaling fast and defining a new category in real time. The work is ambitious, the bar is high, and the opportunity for growth — personal, professional, and financial — is unmatched. Our team moves fast, takes ownership, and is deeply committed to the mission — operating with intensity, staying close to our customers, and pushing each other for excellence. We live by three values: Decisiveness, Simplicity, and Job's Not Finished. We act quickly on clear judgment over perfect information, we believe simplicity is what scales, and we're never satisfied with where we are. If you want to do the best work of your career alongside people who share that drive, we'd love to build with you. At Harvey, the future of professional services is being written today — and we’re just getting started. ROLE OVERVIEW In this role, you'll build the systems that power how we adapt and improve leading open-weight models for legal work. We recently post-trained our first model built for legal work, and we’re now building the team to scale up our post-training efforts. You’ll own the infrastructure behind that effort: distributed training, RL rollout systems, the environments where models learn to use tools and complete complex legal workflows, and the internal systems the team uses to manage data, run evals, and launch and track training jobs. You’ll help decide what we build, what we adopt, and how the pieces fit together. You’ll join a small, high-bar team of hands-on engineers and researchers, where each person owns a large part of the stack. We’re looking for research engineers who have built demanding ML or distributed systems, can debug across the stack, and want to work closely with researchers to make training faster, more reliable, and easier to iterate on. Learn more about our work at harvey.ai/research http://harvey.ai/research. WHAT YOU'LL DO - Scale our post-training stack, supporting SFT and RL on leading open-weight models. - Build distributed rollout infrastructure that coordinates model inference, tool execution, and collection of training experience for long-horizon tasks. - Build the infrastructure for reproducible agent environments where models can interact with documents, tools, and external systems during training and evaluation. - Own the performance and reliability of training runs, including GPU utilization, checkpointing, failure recovery, and observability. - Identify and remove bottlenecks across training and inference to shorten the path from research idea to useful result. - Build the internal tools and services the team runs on: training data management and versioning, running evals and browsing results, and launching and tracking training jobs and experiments. - Integrate models into production, including serving, latency, cost, and online evaluation, so research reaches customers quickly and safely. - Partner closely with researchers to turn experimental workflows into dependable systems while keeping room for rapid experimentation. WHAT YOU HAVE - Experience building ML infrastructure, distributed systems, or research tooling, with ownership of performance, reliability, and operation. - Strong Python and generalist software engineering skills across backend services, data systems, and internal tools, with familiarity with PyTorch, JAX, or similar ML frameworks. - Experience with distributed training or inference, including diagnosing performance bottlenecks and failures across the stack. - Understanding of post-training workflows; experience with RL rollouts, agent environments, or sandboxed tool execution is a plus. - Practical judgment about what to build versus adopt, and the ability to partner with researchers and ship quickly as needs evolve. We are hiring for this role across multiple levels. COMPENSATION $230,000 - $450,000 USD DEPENDING ON YOUR LOCATION, AN APPLICANT PRIVACY NOTICE MAY APPLY TO YOU.

At Harvey, the future of professional services is being written today — and we’re just getting started. ROLE OVERVIEW In this role, you'll build the data and measurement systems that power our post-training, benchmarking, and agent capability efforts. We recently post-trained our first model built for legal work, and we’re now building the team to scale up our post-training efforts. You’ll own synthetic data pipelines, evaluation design, the tasks and grading behind training environments, and the systems that turn feedback from domain experts into training signals and rewards. These are tasks where correctness often can’t be verified automatically, so defining and measuring quality is a core research challenge. You’ll join a small, high-bar team of hands-on engineers and researchers, where each person owns a large part of the work.

Learn more about our work at harvey.ai/research http://harvey.ai/research. WHAT YOU'LL DO - Build synthetic data pipelines that generate, filter, and curate training and evaluation samples for complex legal reasoning and agentic workflows. - Design evaluations and verifiers that reflect real legal work, calibrate them against expert judgment, and investigate where they fail. - Build and maintain capability benchmarks like our Legal Agent Benchmark (LAB), along with product-focused evals that track how models perform on real customer workflows. - Work with legal domain experts to define quality metrics, rubrics, and other grading mechanisms for training and evaluation. - Own training and evaluation data quality, including provenance, coverage, and safeguards against contamination. - Close the loop from product usage and customer feedback to new evaluations and training data, so models improve where customers need them most. - Partner with researchers to investigate model failures, distinguish real gains from misleading metrics, and use findings to guide training and release decisions. WHAT YOU HAVE - Experience building data pipelines, ML evaluation systems, or experimentation tooling, with strong Python skills and ownership of production-quality code. - A rigorous approach to measurement, including statistical reasoning, experimental design, and understanding when a metric can mislead. - The ability to translate ambiguous goals or expert judgment into structured datasets, rubrics, and measurable criteria. - Experience with synthetic data, LLM evaluations, automated raters, or preference data is a plus. Strong data and measurement engineering experience close to ML model development is valuable even without prior LLM work. We are hiring for this role across multiple levels.

Location: London DRW is a diversified trading firm with over 3 decades of experience bringing sophisticated technology and exceptional people together to operate in markets around the world. We value autonomy and the ability to quickly pivot to capture opportunities, so we operate using our own capital and trading at our own risk. Headquartered in Chicago with offices throughout the U.S., Canada, Europe, and Asia, we trade a variety of asset classes including Fixed Income, ETFs, Equities, FX, Commodities and Energy across all major global markets. We have also leveraged our expertise and technology to expand into three non-traditional strategies: real estate, venture capital and cryptoassets. We operate with respect, curiosity and open minds. The people who thrive here share our belief that it’s not just what we do that matters–it's how we do it. DRW is a place of high expectations, integrity, innovation and a willingness to challenge consensus. Fundamental Researcher - Compute Markets The role DRW is seeking a Fundamental Researcher to develop investment views on compute markets and the infrastructure that supports them. You will research the economics of compute supply and demand, form views on the macro forces shaping the market, and translate them into investment recommendations for a compute derivatives strategy. You will work alongside a quantitative researcher who owns the pricing models. Your contribution is an independent, fundamental perspective: understanding the models well enough to test their assumptions against what is happening in the market, and flagging when the market has moved ahead of them. This is a founding seat on a small investment team. We are particularly interested in candidates with credit, commodities or semiconductor research experience who can apply rigorous analysis of cash flows, capacity, contracts and downside risk to a market that is still taking shape. We do not expect deep prior experience in compute. We expect strong analytical foundations and the curiosity to build sector expertise quickly. What you'll do Develop macro and fundamental views on compute. Track and interpret the forces driving supply and demand: AI training and inference demand, hyperscaler and neocloud capital expenditure, chip supply and generational transitions, data center capacity, power availability, financing conditions and policy, including export controls. Translate pricing into investment views. Assess what compute pricing across contract terms and chip generations implies about demand, capacity and scarcity. Identify where prices diverge from fundamentals and recommend how to express those views. Validate pricing assumptions. Develop a working understanding of the pricing models and supply the fundamental evidence behind their key inputs, including supply pipeline, utilization, workload mix and the pace of price declines across hardware generations. Challenge those inputs when the evidence changes. Build research models. Develop supply-and-demand balances, unit economics and scenarios that connect fundamental drivers to compute pricing and investment outcomes, with assumptions documented and testable. Assess counterparties and assets with a credit investor's discipline. Evaluate revenue quality, utilization, cost structure, customer concentration, contractual commitments, leverage, liquidity and refinancing risk. Examine how generational turnover and the falling cost of compute affect asset values, counterparty resilience and recoveries. Make clear recommendations. Present to the Portfolio Manager and Investment Committee, setting out the investment thesis, valuation framework, catalysts, risks and the evidence that would change the view. Build differentiated information sources. Develop a network of industry contacts and data sources across hardware, cloud, data center and power markets to test assumptions and spot inflections early. What we're looking for 5 to 7 years of fundamental investment research experience, ideally in credit research or investing (including structured or asset-backed finance), commodities (particularly power and energy), or buy-side or sell-side coverage of semiconductors and digital infrastructure. A demonstrated ability to turn complex or incomplete information into a clear investment judgment. Strong financial modeling skills and a thorough understanding of cash flow analysis, capital structures and downside scenarios. Enough quantitative fluency to engage with pricing models: understand how they work, interrogate their inputs and judge whether their outputs are consistent with the market. You will not be expected to build or maintain them. An understanding of how a fundamental view translates into a derivatives position such as a forward or swap, or the ability to learn this quickly. The ability to distinguish structural trends from temporary supply-and-demand imbalances and to assess what is already reflected in pricing. A strong interest in compute markets and the drive to build expertise across hardware, cloud services, data centers and power infrastructure. Prior experience in the sector is valuable but not required. Clear written and verbal communication, intellectual independence, and a willingness to challenge assumptions and revise views as evidence changes.
