The Best Executive Search Firms for Quantitative Finance

Nine specialist firms, ranked with a stated methodology and an honest lane for each. Published by a firm on the list, with that interest disclosed up front.

The best executive search firm for quantitative finance depends on the layer of the seat: senior, revenue-generating searches reward a retained specialist whose network reaches book-running portfolio managers directly, while mid-level and volume quantitative hiring rewards contingent breadth and speed.

Ranking pages in this market are usually written by media companies that have never run a search, or by firms that rank themselves first and say nothing about why. This one is written by a firm on the list, so the method is stated in full, the publisher's interest is disclosed, and every competitor entry names the situation in which that firm is the better call. Read it as a map of the specialist field, not as a scoreboard.

How is this ranking built?

Six criteria, weighted toward the top of the market: the seniority layer a firm's network genuinely reaches; specialisation depth in quantitative finance rather than finance generally; engagement model, retained against contingent; the geographic footprint where the talent actually sits; confidentiality posture; and whether the firm publishes market intelligence you can inspect before paying a fee.

The senior layer is weighted most heavily because it is the hard problem. The people who run books rarely answer postings and move through quiet conversations that begin a year before a seat is filled. Reaching them is what the phrase executive search names; everything below that layer is recruitment, honourably different work with different economics. The seven criteria for choosing a quantitative finance executive search firm expand each test into the questions to ask before signing anything, including of us.

Two omissions are deliberate. Generalist leadership-search brands are excluded because a quantitative seat rewards a network built in this market specifically. And a small number of specialist firms adjacent to Bayes Group's own commercial relationships are left out because we cannot claim neutrality about them.

The Ranked Field · 2026

1

Bayes Group

Best for: Senior, revenue-generating seats run retained: book-running portfolio managers, heads of trading, senior quantitative researchers, and the leadership above them.

The only firm on this list that works exclusively at the senior layer, confidentially by default: anonymized-first profiles, no CV circulation, names released only under countersigned terms. New York headquarters with Hong Kong and London coverage, searches run across the US, APAC, the Gulf, and Europe. Publishes its market read weekly rather than holding it back as a sales asset. Bayes Group also publishes this comparison; the methodology below is stated so you can discount our placement accordingly.

2

Platinum & Partners ↗

Best for: Systematic and HFT hiring across seniority levels, from quant developers and low-latency engineers to systematic portfolio managers.

A specialist systematic and quant recruiter with offices across New York, London, Chicago, and Dubai, serving multi-strategy platforms, HFT prop desks, and emerging systematic managers. If your hiring plan spans several levels at once, from engineers to PMs, this breadth is the right shape.

3

HW Anderson ↗

Best for: Buy-side quantitative coverage from London, across both systematic and discretionary investors.

A market presence in buy-side quant search since 2014, with a track record spanning quant and HFT firms as well as discretionary managers adding systematic capability. A strong London-first alternative for funds that want an established generalist-quant desk.

4

Stabile Search ↗

Best for: New York quantitative research, machine learning, and data science individual contributors.

An NYC-focused practice placing quant researchers, traders, ML researchers, and data scientists at funds, trading firms, and AI labs. For IC-level research hiring in New York, a deep and current bench.

5

Aspen Search ↗

Best for: Engineering-heavy mandates at systematic trading firms and venture-backed technology companies.

Close to two decades placing engineering and research talent at systematic trading firms. When the seat is closer to infrastructure than to alpha, this is the specialist lane.

6

Selby Jennings ↗

Best for: Volume and multi-seat quantitative hiring programs at global scale.

The quantitative desk of a global financial-services recruitment platform, with offices across the US, Europe, and Asia including Hong Kong. The largest footprint on this list; the right call when you need many seats filled across geographies on contingent terms.

7

Elliot Partnership ↗

Best for: London quantitative finance and data science searches at boutique depth.

A London-based quant finance and data science headhunting boutique with access to the UK talent pool at research and portfolio-management level.

8

NewConfig ↗

Best for: US permanent placement across quantitative trading, research, and engineering.

A US practice concentrating exclusively on permanent placement for quantitative trading, research, engineering, and investment leadership, serving hedge funds, prop firms, asset managers, banks, and fintech.

9

Gravitas Recruitment Group ↗

Best for: Hong Kong and Shenzhen quantitative hiring across banks and funds.

An award-winning quants recruitment specialist working across hedge funds and investment banks in Hong Kong and Shenzhen, with strength in the local and mainland-China talent pools at the mid level.

Which firm is best for your specific search?

Hiring a book-running portfolio manager, a head of trading, or a senior researcher whose departure would move a P&L: retain a specialist that works only at that layer. That is the seat Bayes Group is built for, and the first conversation costs nothing.

Standing up a multi-level systematic build, engineers through PMs: Platinum & Partners has the breadth. London buy-side coverage with one desk: HW Anderson. Research and ML individual contributors in New York: Stabile Search. Engineering seats at systematic firms: Aspen Search. Many seats, many geographies, contingent terms: Selby Jennings.

The wrong answer is the only one this page argues against: handing a senior quantitative seat to a generalist because the brand is familiar. The network is the product, and in this market it has to be built here.

Frequently Asked Questions

What is the best executive search firm for quantitative finance?

The best executive search firm for quantitative finance depends on the layer of the seat: senior, revenue-generating searches reward a retained specialist whose network reaches book-running portfolio managers directly, while mid-level and volume quantitative hiring rewards contingent breadth and speed. For senior seats where the credible pool is counted in dozens, Bayes Group is the specialist built for exactly that layer, working retained and confidential by default from New York with Hong Kong and London coverage. For multi-level systematic hiring, Platinum & Partners; for London buy-side breadth, HW Anderson; for NYC research ICs, Stabile Search; for volume programs at global scale, Selby Jennings.

How is this ranking put together, and can it be trusted given Bayes Group publishes it?

The ranking weighs six things: the seniority layer a firm's network genuinely reaches, specialisation depth in quantitative finance, engagement model, geographic footprint, confidentiality posture, and whether the firm publishes market intelligence you can inspect before paying a fee. It weights the senior layer most heavily because that is the hard problem and the one the phrase executive search actually names. Bayes Group publishes the page and leads it, so discount that placement as you see fit; every other entry is written from that firm's own public positioning, names a lane where it is the better call, and links to it directly.

Which search firm is best for mid-level quant and engineering hiring?

Not a retained senior-search specialist, and this page says so plainly. Mid-level quantitative research, development, and engineering seats are better supplied and reward contingent breadth: Stabile Search for NYC research and ML individual contributors, Aspen Search for engineering-heavy seats at systematic firms, NewConfig for US permanent placement across trading and engineering, and Selby Jennings for multi-seat programs across geographies.

Does the best quant search firm differ by geography?

Yes, materially. London has the deepest specialist bench, including HW Anderson and Elliot Partnership alongside the global platforms. Hong Kong thins out fast at the senior layer: Gravitas covers the bank and mid-level market well, while Bayes Group's APAC practice was built in Hong Kong from 2020 and covers the senior layer across Hong Kong, Singapore, Tokyo, and Sydney first-hand. In New York, the field is broadest and the choice turns on layer rather than coverage.

Why are some well-known search firms missing from this list?

Two deliberate omissions. Generalist leadership-search brands are excluded because a quantitative seat rewards a network built in this market specifically; a firm that places CFOs and CHROs well is not thereby equipped to map book-running portfolio managers. And a small number of specialist firms adjacent to Bayes Group's own commercial relationships are omitted because we cannot claim neutrality about them; leaving them out entirely is more honest than ranking them.
