Full Stack Developer

£80,000-£110,000

London – Hybrid (4 days in office, 1 day WFH)

Initial contract period with perm switch after 6-12 months.


A leading investment management firm is seeking a Full Stack Developer to join their lean, high‑impact technology team. In this role, you’ll build and enhance tools that automate operational workflows across treasury, collateral, FinOps, and middle‑office functions.

This is a hands‑on position where you’ll work closely with risk, treasury, and operations teams to identify inefficiencies, replace legacy/manual processes, and build scalable solutions that support a fast‑paced trading environment.


What you’ll work on

  • Automating workflows across treasury, accounting, trading and middle‑office operations.
  • Building tools to improve collateral & margin management, capital usage reporting, and trade reconciliation.
  • Designing and implementing API integrations across internal and third‑party systems.
  • Developing in‑house solutions to replace outsourced or legacy technology.
  • Creating data pipelines that improve reporting and analytics for portfolio managers.
  • Owning projects end‑to‑end — from gathering requirements through to deployment.


What you’ll need

  • 5–6 years’ experience as a software engineer in financial services (buy‑side preferred, sell‑side also welcome).
  • Solid background in treasury, collateral, middle‑office, or financial operations technology.
  • Strong programming skills in C# + Python
  • Front‑end experience with Vue.js, React, or Angular.
  • Experience with databases such as SQL Server, Databricks, or Azure SQL.
  • Strong understanding of data structures, automation, and workflow optimisation.
  • Familiarity with Git / CI/CD pipelines.
  • Ability to operate independently in a fast‑moving, high‑ownership environment.


Nice to have:

  • Experience with Broadridge, Sentry, or other treasury/risk platforms.
  • Exposure to data warehousing, security master systems, or trade booking automation.
  • Experience in quant or systematic trading environments.


Why this role?

You’ll have direct ownership, real influence, and the opportunity to modernise critical operational infrastructure in a high‑performing financial environment. Ideal for someone who enjoys autonomy, solving operational pain points, and building robust tools that have immediate business impact.
