Lead Software Engineer | Python | £90k-£100k + 10-30% Bonus | London
£90,000-£100,000 base + 10-30% performance bonus Bonus paid every 4 months London | 3 days per week in the office Python | Django | Flask | APIs | Data Pipelines
I'm working with a growing financial technology business that's built its own proprietary platform, to help investors, originators and asset owners manage complex private credit and asset-backed finance portfolios.
They're now looking for a Lead Software Engineer to join the team and play a key role in the continued evolution of the platform.
And the package is a genuine differentiator: £90k-£100k base + a performance bonus that typically averages between 10-30%, paid every four months.
The Opportunity
This company has recently won a number of new clients, with a significant increase in projects coming onto the their platform. That means you're joining at a point where platform scale, engineering capacity and technical direction are becoming increasingly important. The role remains hands-on. You'll be writing software and working across the core platform, while also acting as a technical reference point for the wider engineering team.
What You'll Be Doing
- Designing and building core backend services, APIs, data pipelines and calculation engines
- Contributing to the architecture and technical direction of their platform
- Improving the scalability, reliability and maintainability of the platform
- Working closely with Product, Engineering and domain specialists to turn complex requirements into robust software
- Helping establish engineering best practices around testing, code quality, observability and delivery
- Mentoring other engineers and helping raise the technical bar across the team
- Taking increasing ownership of key components and areas of the platform
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.
The Technical Environment
Python is at the heart of the platform, with Django, Flask, APIs, data-processing workflows and relational databases forming much of the day-to-day environment. They're particularly interested in engineers who can sit comfortably between backend software engineering and data-heavy systems. Experience with Airflow, orchestration, ETL or data processing would be valuable, but they're not looking for a pure Data Engineer. The sweet spot is someone who considers themselves a strong software engineer first, with the ability to work comfortably with complex data and financial workflows.

Your very own career expert that helps elevate your application to the next level.
What They're Looking For
- Strong commercial software engineering experience, ideally with Python
- A strong backend engineering background
- Experience building and owning APIs, services or data-heavy applications
- Good architectural and technical decision-making
- Experience mentoring or providing technical leadership to other engineers
- Comfortable working in a growing environment where requirements aren't always fully defined
- Someone who wants to remain hands-on while having greater influence over technical direction
Why Join?
£90k-£100k base + 10-30% performance bonus, paid every four months. Alongside the compensation, you'll be joining a relatively small engineering function where your technical decisions can genuinely influence the direction of the platform. It's a good opportunity for someone who wants to stay hands-on technically, while taking on more responsibility for architecture, engineering standards and the development of other engineers.
If you're a senior/lead Python engineer looking for a role where you can stay hands-on, influence architecture and have meaningful ownership over a growing platform, I'd be keen to speak.
