Buy Side Recruitment
Specialist Technology Hiring for the Firms Where Every Hire Has a Direct Line to Performance
Harrington Starr partners with hedge funds, systematic funds, and multi-strategy firms to place technology, quantitative, data, and transformation professionals who help investment firms generate performance, manage risk, and scale effectively. From front-office engineering to quant infrastructure, data to cloud, we recruit across the full technology stack for firms where the margin for error is low, and the stakes of a mis-hire are high.
The buy side has always demanded more from its technology teams than most sectors. What has changed is the scope of that demand. Systematic strategies have moved from niche to mainstream. Alternative data is now a front-office tool rather than an experiment. AI has entered the investment process itself, not as a future consideration but as a present one that requires governance, auditing, and proper development from the start.
The result is a talent market where the specification for a strong hire has grown considerably, but the pool of candidates who genuinely meet it has not kept pace. A data engineer who understands portfolio construction. A software engineer who has worked inside a live trading environment and knows what a P&L-impacting outage feels like.
These candidates exist. They are also rarely looking, rarely visible, and rarely responding to job adverts. Reaching them requires a presence in the market that goes beyond posting roles and waiting.
Key pressures shaping buy-side hiring right now:
- Quantitative and systematic strategies are scaling headcount in engineering and research technology, intensifying competition for a narrow talent pool.
- AI adoption is outpacing most firms' governance frameworks, creating an urgent demand for professionals who understand both the capabilities and the risks.
- Front-office data infrastructure has become a strategic differentiator, and the gap between firms that have built it well and those that have not is widening.
- Regulatory obligations under MiFID II, DORA, and the EU AI Act are landing directly on technology teams, raising the bar for the domain knowledge a hire needs on day one.
- Attrition risk is higher than it appears. The firms losing their best technology people are often not losing them to direct competitors; they are losing them to better cultures at comparable pay.
Expertise We Hire Across
The Roles We Place in Buy-Side
The firms we work with are not running standard tech functions. Their technology teams sit close to the investment process, sometimes inside it, and the hiring requirements reflect that proximity. We recruit across the following areas of buy-side technology.
Trading Infrastructure & Front-Office Engineering
The professionals who build and maintain the systems closest to execution. This is high-consequence work; connectivity failures, latency spikes, and OMS instability are not IT problems; they are investment problems. The engineers we place in these roles understand that distinction before they walk through the door.
We work across mandates for:
- OMS and EMS developers, support engineers, and implementation specialists
- Low-latency and execution infrastructure engineers
- FIX and connectivity specialists
- Front-office application engineers and technology leads
Quantitative & Research Technology
The boundary between quantitative research and engineering has blurred significantly. The most valuable professionals in this space are those who sit confidently on both sides of it, able to work alongside portfolio managers and researchers while building the infrastructure that turns ideas into deployable strategies.
We work across mandates for:
- Quantitative developers and research engineers
- Systematic strategy developers
- Quantitative analysts with programming depth
- Research technology and data science leads
Data Engineering & Investment Analytics
Data is the raw material of modern investment management, and the quality of what a firm can do with it depends entirely on how well it has been sourced, cleaned, governed, and made accessible. We place specialists who build this infrastructure across both the investment and operational sides of buy-side firms.
We work across mandates for:
- Data engineers and data architects
- Alternative data specialists
- BI and investment reporting professionals
- AI and machine learning engineers working within investment contexts
Cloud, Infrastructure & Operational Resilience
Investment management firms operate in an environment where downtime is not an inconvenience; it is a risk event. As buy-side firms migrate legacy infrastructure and modernise platforms, the demand for cloud and infrastructure talent that understands what operational resilience means in a regulated, high-stakes environment continues to grow.
We work across mandates for:
- Cloud architects and engineers across AWS, Azure, and GCP
- DevOps and platform engineers
- Application support and infrastructure specialists
- Site reliability engineers with financial services exposure
Technology Change & Investment Platform Leadership
Transformation programmes on the buy side often fail when the people running them do not understand what they are transforming. We recruit the programme leaders, business analysts, and product professionals who can navigate both the investment rationale and the technology delivery.
We work across mandates for:
- Technology transformation and programme leads
- Business analysts with front-to-back investment domain knowledge
- Product managers and owners on investment and trading platforms
- Senior technology leadership, including Head of Technology and CTO appointments
Specialist Recruitment for Buy-Side Technology Teams
The buy side is not a vertical that rewards generalist methodology. A consultant who does not know the difference between an OMS and an EMS, who cannot read a job specification that references systematic alpha generation, or who has never spoken to a quant developer about what actually makes a role attractive, is not going to reach the right candidates, and is not going to represent a firm credibly when they do.
Our buy-side recruitment specialists work this market daily. They know which firms are growing their technology headcount and why, which candidates are open to conversations they would not have six months ago, and how the compensation picture has shifted globally. That market intelligence is what makes the difference between a search that runs for six months and one that delivers.
What Distinguishes the Best Technology Hires on the Buy Side
Hiring managers across the buy side are not short of applicants. What they need are technology professionals who can perform in environments where systems, data, and infrastructure are closely tied to investment performance. These are the qualities our consultants assess to identify candidates who can succeed immediately.
A technology professional who understands the investment context in which they are operating is worth considerably more on the buy side than one who does not. This is not about asking engineers to become portfolio managers. It is about whether a data engineer understands why reference data quality matters in a pricing context, or whether a software developer understands what the operational impact of their system being unavailable at open actually means.
The regulatory environment across investment management has grown considerably more complex and more technical. MiFID II, DORA, the EU AI Act, and SMCR are not concerns that sit with compliance teams and are occasionally passed across to a technology desk. They shape architectural decisions, data governance frameworks, audit trails, and the documentation and explanation of automated systems. The professionals who are most valuable on the buy side are those who build with this in mind from the start, not those who need it retrofitted at the end.
The best technology hires at investment management firms are not the ones who disappear into the engineering team and only surface during sprint reviews. They are the ones who can sit in a risk committee meeting and explain a data architecture decision, who can tell a portfolio manager what a system limitation means for their workflow without making them feel like it is their problem to solve, and who can hold both conversations without losing credibility in either room. This capability is genuinely uncommon. We look for it deliberately.

Frequently Asked Questions
What types of firms do you work with on the buy side?
Hedge funds, long-only and multi-asset managers, systematic and quantitative investment firms, family offices with institutional technology requirements, and the fintech vendors and software businesses whose products the buy side runs on. If the role sits at the intersection of technology and investment management, we work on it.
Do you recruit for both permanent and contract roles?
Yes. Many buy-side firms employ a blend of permanent hires for strategic, long-term capabilities and specialist contractors for defined delivery phases or peak-period capacity. We work across both within the same client relationship, so firms do not need a separate partner for each.
What seniority levels do you cover?
Across the full range, from analyst-level engineers and application support professionals through to CTO, Chief Data Officer, and Head of Engineering appointments. Senior and executive searches on the buy side run as retained mandates, with discreet market mapping and in-depth assessment before any shortlist is presented.
How do you reach candidates who are not actively looking?
The most valuable professionals in buy-side technology are rarely on job boards. They are reachable through the relationships our consultants have built over years of working this market, conversations that happen because of trust and relevance, not because of a cold InMail. That network is the core of what we offer.
How do you stay current with what is happening in buy-side technology?
By being in the market constantly, talking to technologists, portfolio managers, and product leaders across the buy side, running our podcast and content programme, tracking regulatory and investment technology developments, and maintaining the candidate and client relationships that give us a real-time picture of where the market is. That is what makes our buy-side recruitment specialists useful as advisors rather than just as a search function.
How do you stay current with developments across retail financial services?
Our consultants engage directly with banking and fintech professionals every day. Combined with our content programme, industry events, podcast network and ongoing market research, this gives us visibility into hiring trends, technology investment priorities and the talent challenges shaping retail financial services. This market knowledge allows us to provide informed recruitment advice rather than simply filling vacancies.
