Full Stack Software Engineer — Node.js · React · JavaScript
Miller Maxwell | London — Hybrid (2 days in office) | Permanent
Miller Maxwell is working with a well-established electronic brokerage that is rebuilding its core trading platform from the ground up. This is not a greenfield startup product — it is a system that moves billions of pounds of daily flow, used in real time by front-office traders across three global offices. The engineering standards reflect that.
The Full Stack Software Engineer Role:
You will own both ends of the stack. On the front end, you will be building React interfaces that surface live market data cleanly and quickly under genuine load — where a sluggish render has real consequences. On the back end, you will be designing and running the Node.js services and APIs that feed those interfaces, processing high-volume, real-time data at pace.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What the Full Stack Software Engineer Will Be Doing:
- Building low-latency React UIs for real-time equities data — performance and render speed are non-negotiable
- Designing and running the Node.js services and APIs behind those interfaces, handling high-volume market data reliably
- Building and maintaining JavaScript libraries purpose-built for demanding financial data display
- Translating complex trading workflows into clean, intuitive end-to-end solutions with the desk and engineering teams
- Taking ownership of architecture and code quality across the full stack — with real influence over technical direction
Full Stack Software Engineer Requirements:
- 5 years of commercial full-stack experience with a strong JavaScript foundation across front and back end
- React expertise — clean component architecture and the judgement to know when not to reach for the framework
- Solid, production-grade Node.js — building and running real backend services, not just tooling or scripts
- A track record delivering high-volume applications under real-world performance constraints
- Strong communication skills across engineering, product, and trading desk stakeholders
- Financial services or real-time data background — not essential, but a genuine differentiator
