Junior C# Engineer – Front Office Platform (London)
We’re working with a high-performing investment firm building and evolving a core platform used directly by traders and portfolio managers across the business.
This isn’t a typical junior backend role. It’s a position that gives you immediate exposure to front office users, with a clear pathway into more commercial or trading-facing roles over time.
Why this role stands out
* Direct front office exposure from day one
* You’ll be working on systems used daily by traders and PMs, not internal tooling that sits in the background
* Clear progression beyond pure engineering
* This team has a proven track record of people moving into more commercial and trading-facing roles over time
* High-impact work early in your career
* You’ll see how systems, data, and tooling directly influence decision-making and outcomes
* Steeper learning curve than most junior roles
* Small team, strong engineers, and close interaction with end users
What you’ll be doing
* Building and maintaining backend systems that support trading and research workflows
* Working closely with traders and PMs to understand requirements and deliver solutions
* Contributing to a centralised platform used across multiple teams
* Supporting and improving existing systems, including troubleshooting and user interaction
* Gradually taking on more ownership as your understanding of the platform and domain grows
Tech environment
* C# / .NET (core focus)
* Strong emphasis on computer science fundamentals (algorithms, data structures, OOP)
What they’re looking for
* 1–2 years commercial experience with C# / .NET
* Strong academic background in Computer Science (or closely related discipline)
* Solid grounding in core engineering fundamentals
* Curious, proactive, and comfortable working in a fast-paced environment
* Interested in understanding how technology is used in real-world decision making
Important to note
This role includes a meaningful support component initially, working closely with users, troubleshooting issues, and understanding how the platform is used day-to-day.
It’s best suited to someone who values:
* Front office exposure
* Learning how systems are used in practice
* A longer-term pathway into more commercial or trading-aligned roles
