Role: Principal Engineer

Salary: £110,000 - £150,000 per annum

Location: Office based in London but able to support remote workers

In just a few years, our FinTech client has become one of the UK's fastest-growing businesses, using advanced data analytics to provide rapid credit and funding solutions to SMEs. The company's expansion is driven by a combination of innovative product-led technology and strong commercial performance.

They are now seeking a Principal Engineer to take ownership of the technical strategy for critical, customer-facing systems. This role is about driving architectural leadership that directly translates to business success. You will be central to scaling a platform that is redefining lending in the SME space.

• Own the Architecture: Lead the design of systems that leverage real-time data to tailor bespoke product offers.
• Strategic Impact: Partner closely with Product, Strategy, and Commercial teams to influence the business roadmap.
• Measurable Success: Your performance will be measured by your ability to drive significant lifts in conversion, retention, and revenue.
• Cutting-Edge Stack: Work with an object-oriented backend foundation (e.g., Python/Django, PostgreSQL, AWS) at hyper-scale.

Requirements for the Principal Engineer:

• ️ Proven architectural leadership and deep technical expertise in backend technologies (preferably Python/Django or React/Typescript) at scale.
• Strong track record of collaboration with non-engineering stakeholders (Product, Commercial) to deliver measurable business outcomes.
• Experience in FinTech, E-commerce, or Product-Led SaaS businesses where engineering directly impacts commercial metrics (e.g., conversion rate).
• Recent roles must demonstrate a blend of hands-on delivery with strategic system design, avoiding roles focused purely on internal platform or infrastructure.
• Management experience is a nice to have as you will manage a small team of engineers.

This is a career-defining chance to lead the technical and commercial strategy at a hyper-growth FinTech, shaping the next generation of SME lending.
