Lead Software Engineer

Lead Software Engineer (C#/.NET) - London

Location: London (Hybrid) |
Sector: Financial Services
Type: Permanent
Salary: Circa130k + bonus + benefits

We're partnering with a well-regarded trading and investment firm who want someone technically sharp enough to design complex distributed systems and credible enough to lead a team - not one at the expense of the other.

If you've been waiting for a role that rewards both sides of your skill set, this is it.

The Role

You'll lead a small, focused team of engineers building systems that sit at the heart of the business - touching trading, compliance, and operations. You'll own architecture decisions, drive delivery, and shape how the team works. Critically, you'll stay hands-on: this firm values engineers who can still get into the detail.

You'll have the autonomy to do things properly - best practices in testing, CI/CD, and system design aren't aspirational here, they're expected.

What You Bring

• 8+ years in C#/.NET, with real experience leading or mentoring engineers
• A strong portfolio of distributed systems built for production, not just proof-of-concept
• Python and SQL alongside your .NET work
• The ability to talk to a quant as comfortably as a business stakeholder
• Some familiarity with financial market data (Bloomberg, Reuters or similar)

A bonus if you have: exposure to the order-to-trade life cycle, Bloomberg APIs, Docker or AWS.
