We are working with a well-backed, newly launched hedge fund in London, building a next-generation long/short equity platform that blends deep fundamental insight with advanced quantitative analytics.


This is a greenfield opportunity to help design and build the core research, risk and portfolio analytics tooling that will directly support the investment and risk decision-making process from day one.


You will work in a small, elite team, reporting into the CRO and partnering closely with senior investment professionals and the risk leadership, with real ownership and visibility over what you build.


The Opportunity


  • Build and own core data and compute libraries used across research, risk and data science
  • Design and implement research infrastructure including back-testing, portfolio optimisation and risk analytics
  • Develop internal tools and applications used daily by PMs, analysts and the CRO
  • Work across the stack (Python backend, analytics, some front-end exposure) to deliver production-grade solutions
  • Take ideas from concept to production in a fast-moving, low-bureaucracy environment


This is not a maintenance role. You will be solving open-ended problems, making architectural decisions, and shaping how analytics and risk are embedded into the investment process.


Background

We are open-minded on background, but you will likely come from one of the following:

  • Top technology firms (e.g. Google, Meta, Amazon, Microsoft) with experience building internal analytics, data or ML platforms
  • Quant hedge funds or systematic trading firms, working as a Quantitative Developer or Research Engineer
  • Research-led or data-heavy environments where engineering quality and problem-solving matter


Core Requirements

  • Strong Python experience in production environments (pandas, numpy, scipy or similar)
  • Experience building research, analytics or decision-support tooling
  • Solid software engineering fundamentals: testing, version control, deployment
  • Comfortable working with ambiguity and taking ownership of greenfield systems
  • Strong communicator, able to work closely with non-engineering stakeholders


Nice to have

  • Experience with optimisation, back-testing or risk models
  • Exposure to ML frameworks or LLMs
  • Some front-end experience (React / TypeScript)

The Skills Gap in Data Science Jobs: What Universities Aren’t Teaching

Data science has become one of the most visible and sought-after careers in the UK technology market. From financial services and retail to healthcare, media, government and sport, organisations increasingly rely on data scientists to extract insight, guide decisions and build predictive models. Universities have responded quickly. Degrees in data science, analytics and artificial intelligence have expanded rapidly, and many computer science courses now include data-focused pathways. And yet, despite the volume of graduates entering the market, employers across the UK consistently report the same problem: Many data science candidates are not job-ready. Vacancies remain open. Hiring processes drag on. Candidates with impressive academic backgrounds fail interviews or struggle once hired. The issue is not intelligence or effort. It is a persistent skills gap between university education and real-world data science roles. This article explores that gap in depth: what universities teach well, what they often miss, why the gap exists, what employers actually want, and how jobseekers can bridge the divide to build successful careers in data science.

Data Science Jobs for Career Switchers in Their 30s, 40s & 50s (UK Reality Check)

Thinking about switching into data science in your 30s, 40s or 50s? You’re far from alone. Across the UK, businesses are investing in data science talent to turn data into insight, support better decisions and unlock competitive advantage. But with all the hype about machine learning, Python, AI and data unicorns, it can be hard to separate real opportunities from noise. This article gives you a practical, UK-focused reality check on data science careers for mid-life career switchers — what roles really exist, what skills employers really hire for, how long retraining typically takes, what UK recruiters actually look for and how to craft a compelling career pivot story. Whether you come from finance, marketing, operations, research, project management or another field entirely, there are meaningful pathways into data science — and age itself is not the barrier many people fear.

How to Write a Data Science Job Ad That Attracts the Right People

Data science plays a critical role in how organisations across the UK make decisions, build products and gain competitive advantage. From forecasting and personalisation to risk modelling and experimentation, data scientists help translate data into insight and action. Yet many employers struggle to attract the right data science candidates. Job adverts often generate high volumes of applications, but few applicants have the mix of analytical skill, business understanding and communication ability the role actually requires. At the same time, experienced data scientists skip over adverts that feel vague, inflated or misaligned with real data science work. In most cases, the issue is not a lack of talent — it is the quality and clarity of the job advert. Data scientists are analytical, sceptical of hype and highly selective. A poorly written job ad signals unclear expectations and immature data practices. A well-written one signals credibility, focus and serious intent. This guide explains how to write a data science job ad that attracts the right people, improves applicant quality and positions your organisation as a strong data employer.
