Lead Python Engineer Up to £140K + Bonus + Equity
We are partnering with a profitable fintech scale-up seeking a Lead Python Engineer to play a key role in building its US investment infrastructure.
The business has established a successful investment platform in the UK and is now building the technology, workflows and financial infrastructure required to support investing across US markets. This is a hands-on leadership role where you'll lead a small pod of engineers whilst remaining deeply involved in architecture, design and software development.
The Opportunity
You'll help design and build the systems that underpin trading, execution, settlement, portfolio management and investment operations for US-listed products. You'll join a highly collaborative engineering team and have significant influence over technical direction, architecture and delivery as the platform continues to scale.
