Head of Quantitative Engineering - CTO Visibility - Global Macro Hedge Fund - London

The Firm

A high-performing, discretionary macro hedge fund is in a genuine build phase across its

Trading Technology platform. The firm manages approximately $18bn in assets and is scaling

beyond 400 people globally, deliberately avoiding mega-fund scale, so engineering teams remain

tight, senior, and highly impactful.

The strategy is fixed income relative value. Trading execution is fast and complex. This is not a systematic fund, but it operates with a level of technological intensity that rivals the best quant shops in the world. The ambition is deliberate and focused: grow thoughtfully, with the depth and culture of a world-class institution, not the sprawl of a multi-manager platform.

A Rare Executive Opening

This is a rare opening within the firm's executive technology leadership.

The firm's technology organisation is co-led by two experienced tech executives, one a long-tenured leader who has been with the firm since its earliest days, overseeing teams spanning

core technology, discretionary and systematic trading technology, infrastructure, and multiple

quantitative engineering functions; the other is a former MD from two of the most respected

names in quantitative finance, leading risk technology, core development, and market data.

The incoming Head of Quantitative Engineering will take direct ownership of two to three of

those quantitative engineering teams, working in close partnership with both Co-CTOs. This is

not a role that sits adjacent to leadership; it is embedded within it. You will carry genuine

weight in shaping the firm's architectural direction, integration strategy, and technology vision

at the highest level.

What You'll Own

You will lead multiple trading and quantitative technology teams, setting direction through

strong tech leads rather than managing day-to-day execution yourself. The expectation is true

player-manager depth: you are comfortable owning architectural decisions hands-on while

also operating as a senior voice in the firm's broader technology leadership.

A significant part of this role is integration, breaking down silos across systems and teams,

driving platform coherence at scale, and building a more unified technical architecture across a

business that spans London and New York. The firm's current priorities include expanding its

trading businesses, advancing AI initiatives, and deepening its data capabilities. You will have

a meaningful scope to shape all three.

Autonomy here is real. The firm moves quickly, thinks carefully, and backs its leaders to act.

The Ideal Candidate

You have roughly a decade of engineering leadership behind you and have, at some point, run

an organisation of fifty or more engineers. You know what good looks like at scale, and you

know the difference between managing headcount and actually building something.

Technical depth is essential. You should be comfortable owning architectural decisions

yourself, not just delegating them. You are technology-agnostic when it comes to language and

stack; what matters is rigour, not loyalty to any particular toolchain.

Exposure to equities is beneficial, and experience with derivatives is a plus, but neither is a hard requirement. What the firm is looking for above all is someone who combines the technical

authority of a principal engineer with the organisational maturity of a seasoned leader,

someone who has operated at the top of a demanding, high-performance environment and

knows how to earn the respect of exceptional people.

The engineers who will do their best work here are those who want to build

something genuinely enduring, within an institution that has the resources, the

talent, and the ambition to make that possible.
