Frontend Developer – £650/day – 6 months – Inside IR35 – 3 days onsite (London)
React or Svelte – Commodities Trading – AWS – TypeScript
You'll be working for a leading energy trading business, building out a modern post-trade platform that's genuinely pushing boundaries – live PnL, intraday position reporting, and digitised front office workflows.
This is a business that backs its tech, delivers fast, and builds for the long-term.
The must-haves:
Strong React or Svelte experience (this needs to be hands-on and recent)
TypeScript
Built modern UIs as part of a product team
Comfortable working in fast-moving agile squads
Experience in commodities or trading (preferred but not essential)
Experience in Python or AWS Services - if you have both this will make you a front runner for this position.
Nice to haves (in order of priority – at least one or two is needed):
# Python (commercial experience)
# AWS services – S3, ECS, AppSync
# GraphQL or REST APIs
# Kafka or message queue systems
# PostgreSQL or NoSQL database experience
