Join a leading systematic trading firm with a strong presence across equities and futures. We’re looking for a hands-on Python Quant Developer to lead and expand the centralised back-testing and research infrastructure that powers all systematic strategies.


The Role

This position is ideal for someone who began their career as a software developer and has evolved into a quantitative developer, combining deep technical expertise with a strong grasp of trading logic.


You’ll take ownership of building and optimising back-testing frameworks, APIs, and algorithmic trading systems, ensuring the team’s research and execution capabilities remain best-in-class.

While the primary focus is on engineering and infrastructure, you’ll also contribute to strategy development and idea testing from time to time, collaborating closely with systematic traders.


Key Responsibilities

  • Lead the design and optimisation of back-testing and research infrastructure for systematic strategies
  • Build and maintain APIs and automation tooling to support trading and research workflows
  • Develop and scale robust systems for mid-frequency equities and futures trading
  • Collaborate with quants and traders to implement and refine algorithmic trading and bot systems
  • Contribute to occasional strategy research and prototype development
  • Manage and mentor junior developers, ensuring high coding and testing standards


Requirements

  • 4–5 years of Python development experience in trading, finance, or other data-heavy environments
  • Proven experience building back-testing systems, APIs, or automation pipelines
  • Strong understanding of data structures, algorithms, and software engineering best practices
  • Track record of designing scalable, production-grade systems
  • Excellent problem-solving, collaboration, and communication skills


Nice to Have

  • Experience with NumPy, Pandas, Cython, or Numba
  • Exposure to market microstructure, risk modelling, or quantitative research
  • Experience developing and maintaining live trading bots or algo execution systems
  • Background in mentoring or technical leadership within a quant or trading team

Data Science Recruitment Trends 2025 (UK): What Job Seekers Need To Know About Today’s Hiring Process

Summary: UK data science hiring has shifted from title‑led CV screens to capability‑driven assessments that emphasise rigorous problem framing, high‑quality analytics & modelling, experiment/causality, production awareness (MLOps), governance/ethics, and measurable product or commercial impact. This guide explains what’s changed, what to expect in interviews & how to prepare—especially for product/data scientists, applied ML scientists, decision scientists, econometricians, growth/marketing analysts, and ML‑adjacent data scientists supporting LLM/AI products. Who this is for: Product/decision/data scientists, applied ML scientists, econometrics & causal inference specialists, experimentation leads, analytics engineers crossing into DS, ML generalists with strong statistics, and data scientists collaborating with platform/MLOps teams in the UK.

Why Data Science Careers in the UK Are Becoming More Multidisciplinary

Data science once meant advanced statistics, machine learning models and coding in Python or R. In the UK today, it has become one of the most in-demand professions across sectors — from healthcare to finance, retail to government. But as the field matures, employers now expect more than technical modelling skills. Modern data science is multidisciplinary. It requires not just coding and algorithms, but also legal knowledge, ethical reasoning, psychological insight, linguistic clarity and human-centred design. Data scientists are expected to interpret, communicate and apply data responsibly, with awareness of law, human behaviour and accessibility. In this article, we’ll explore why data science careers in the UK are becoming more multidisciplinary, how these five disciplines intersect with data science, and what job-seekers & employers need to know to succeed in this transformed field.

Data Science Team Structures Explained: Who Does What in a Modern Data Science Department

Data science is one of the most in-demand, dynamic, and multidisciplinary areas in the UK tech and business landscape. Organisations from finance, retail, health, government, and beyond are using data to drive decisions, automate processes, personalise services, predict trends, detect fraud, and more. To do that well, companies don’t just need good data scientists; they need teams with clearly defined roles, responsibilities, workflows, collaboration, and governance. If you're aiming for a role in data science or recruiting for one, understanding the structure of a data science department—and who does what—can make all the difference. This article breaks down the key roles, how they interact across the lifecycle of a data science project, what skills and qualifications are typical in the UK, expected salary ranges, challenges, trends, and how to build or grow an effective team.
