Back-end software engineer

Software Engineer | C# / SQL / Event‑Driven Systems | Front‑Office Delivery | £81,000 | Commodities & Energy | Hybrid, UK

A Software Engineer is required to join a commercial‑facing Front Office Delivery group responsible for building and maintaining the systems that power real‑time trading workflows across European power markets. This team sits directly between trading, operations and enterprise technology, delivering platforms that query live positions, generate market orders, orchestrate operational processes and feed structured messages into trade‑capture systems

.The work is fast‑moving, highly collaborative and deeply technical. You’ll be working on systems that traders and analysts rely on every day tools that must be accurate, resilient and capable of handling high‑integrity data flows. The environment rewards engineers who can understand complex systems quickly, break down ambiguous requirements, and design solutions that balance robustness with delivery speed

You’ll be involved end‑to‑end: defining architectures, building distributed services, modernising legacy workflows, and contributing to front‑end features used by desks to launch batches, optimise processes and manage explicit orders. The team values engineers who enjoy learning new technologies, exploring new problem spaces and building systems that are genuinely supportable. There is also a strong focus on leveraging AI tooling to improve code quality, test coverage and delivery efficieny.

The Team

The Front Office Delivery team is responsible for the systems that keep trading operations moving. This includes:

Real‑time, event‑driven services that react to market data, position changes and operational triggers

Platforms that generate, modify and close market orders across multiple Europeanhubs

Workflows that transform structured files (XML, CSV) into enterprise‑grade trade‑capture messages

Building front‑end interfaces that consolidate operational actions into a single, orchestrated experience

Designing architectures both tactical and enterprise and delivering them end‑to‑end

Ensuring systems are supportable, maintainable and robust under real‑world trading condit

ions

This is a team where engineers work closely with desks, analysts and business owners, shaping solutions that have immediate commercial im

pact.
