Principal Engineer - We're working with a leading fintech scale-up that's transforming how small businesses access finance. Backed by a strong track record and an ambitious mission, they're now looking for a Principal Engineer to lead the next phase of innovation within one of their most critical product areas.
This is a strategic leadership role offering exceptional autonomy and influence. You'll head up the evolution of a high-impact platform responsible for generating personalised credit offers - a core driver of the business's growth and customer experience.
The Opportunity
As Principal Engineer, you'll take ownership of the technical strategy and architecture for dynamic, data-driven systems that determine the financial products offered to new customers. This is a unique chance to define the future of adaptive credit systems, driving smarter, faster and more relevant lending decisions using real-time data and experimentation.
The Principal Engineer will work closely with senior leadership across engineering, data, product and design. You'll also mentor engineers, steer long-term vision and ensure delivery aligns with key business outcomes.
What Makes This Role Stand Out?
- Strategic Impact: You'll lead the architectural vision and execution of systems at the heart of a high-growth fintech.
- Technical Ownership: Full responsibility for evolving and scaling a domain-critical platform.
- Cross-Functional Collaboration: Partner with experienced teams across disciplines to shape solutions from the ground up.
- Mission-Driven Environment: Work for a business that's empowering small businesses and making finance more accessible.
What We're Looking For:
- Strong experience in systems architecture and software development (object-oriented languages).
- Proven ability to deliver large-scale technical projects in fast-paced environments.
- A business-oriented mindset: you can translate complex problems into scalable, value-driven solutions.
- A collaborative leader who has mentored teams and influenced product direction.
- Experience working with complex domain models and evolving codebases.
Bonus skills include: Python, Django, PostgreSQL, event-driven data systems, machine learning familiarity and frontend awareness.
