49 Quant Trading Firms: List, Careers & Research Guide

Looking for quant firms to apply to? This directory covers 49 employers, from proprietary trading firms and electronic market makers to systematic investment managers, multi-manager platforms and a bank with quantitative roles. Start with the business focus, then investigate the specific trading, research or engineering job.

For a ranked starting shortlist and role-specific recommendations, read the quant firm tier list. This page is the broader employer directory: each entry links to a company profile and the employer’s own website.

Quant employers by the work you want to do

These groupings describe useful starting points rather than strict boundaries. Firms can operate several strategies and hire across all three main job families. A software engineer at a systematic manager may work on research infrastructure, while a researcher at a market maker may focus on signals or execution.

How to compare the firms on your list

Start with the team and role

“Quant” can mean a trader making decisions in live markets, a researcher developing forecasts, an engineer building trading infrastructure, or an analyst validating a bank’s pricing models. Write down the work you would actually do before judging an employer’s reputation.

If a position supports an investment team, ask about the strategy, data, horizon and reporting line. If it supports a shared platform, ask which researchers or traders use the system and how success is measured. Those answers help you decide which projects and interview topics to prioritize.

Compare salary on a consistent basis

Use our quant salary guides to separate base pay from signing payments and bonuses. The same firm can publish very different bands for a graduate researcher, an experienced trader and a principal engineer. Match location, seniority, currency and pay period before comparing the numbers.

For example, IMC’s cited Chicago graduate researcher role lists $250,000 base, while its graduate software role lists $200,000. HRT’s US 2027 algorithm-development intake lists $300,000. These are role-specific employer disclosures, not company-wide averages. The IMC salary guide and HRT salary guide link the original sources and scope.

Match the entry route to your background

Undergraduates and master’s students: check campus intake dates, graduation windows and internships. Build evidence in mathematics, coding and problem solving. An unrelated major does not automatically rule out a role, but you need to demonstrate the required skills.

PhD candidates and researchers: target roles where your methods transfer. Explain your contribution, the data, the experiment and how you tested the conclusion. Use the research project checklist to make that evidence readable to an interviewer.

Software engineers: distinguish research tooling from low-latency execution. A strong general engineering background can be relevant, but each application should connect your experience to the actual systems and constraints in the posting.

Career changers: identify the smallest set of skills you need to demonstrate for a specific role. A broad interest in finance is less persuasive than a well-tested project, a clear explanation of your work and strong fundamentals.

Build an application tracker

Use one row per vacancy, not just one row per company. A useful tracker contains:

Apply through the employer’s official route. The quant job board highlights recently checked vacancies and keeps reviewed role references available separately. For an older listing, follow the employer link and confirm the exact vacancy before investing time in an application.

Prepare by job family

Quant trader

Practice probability, expected value, mental calculation and making decisions when information changes. Explain the assumptions behind an answer and the risk of acting on it. For systematic trading, add statistics and programming. Explore trader salary examples to understand how role and office change the comparison.

Quant researcher

Strengthen statistics, linear algebra, programming and experimental design. Prepare a project that you can explain from hypothesis to result, including a baseline, out-of-sample validation and failure cases. Review researcher salary examples and make your application specific to the team’s work.

Quant developer

Prepare algorithms, data structures and the systems or numerical skills required by the role. For low-latency work, include concurrency, memory, operating systems and profiling. For research platforms, emphasize reliable data processing and reproducible experiments. See the developer salary guide for graduate and experienced examples.

Frequently asked questions

How many quant firms are there?

There is no single official count: definitions vary, and quantitative teams exist inside banks, investment managers and technology-driven trading firms. This directory covers 49 named employers with linked company profiles. It is a starting universe for research, not a claim to list every firm.

Are all these firms hedge funds?

No. The list includes proprietary traders, market makers, investment managers, multi-manager platforms and a bank. Citadel and Citadel Securities, for example, are distinct businesses. Read the role and business description before assuming the same career path or compensation structure.

Which firms should I apply to first?

Prioritize positions where you can demonstrate the main requirements and meet the eligibility criteria. Then add a mix of ambitious targets and specialist employers that fit your background. Use the editorial tier list to learn the landscape, not as a reason to ignore a well-matched team.

Do smaller firms offer easier interviews?

Size alone does not establish interview difficulty or hiring probability. A small firm can have a highly specialized role and few openings. Focus on the requirements, your evidence and the preparation needed for the role.

What should I do after choosing my target firms?
