Senior Software Engineer - London
Zopa
You will design and evolve the services that power core banking products. The systems you help build process thousands of financial transactions every day. They must be scalable, resilient and secure. When money moves, it has to work. Every time.
But this role goes beyond implementation.
You will shape technical direction. Influence cross-team initiatives. Own complex, high-impact work from concept through to production. You will help decide not just how we build, but what we build and why.
This is senior in impact, not just title.
We’re growing across several of our product-engineering tribes at Zopa, with current opportunities in Current Accounts, Lending, Credit Cards and Product Enablement.
Your impact:
Owning complex initiatives end to end, from idea to measurable outcome
Designing scalable backend systems that stand up to real-world scale and complexity
Making architectural decisions that balance immediate delivery with long-term sustainability
Bringing structure and clarity to ambiguous problems
Influencing prioritisation and trade-offs across teams
Raising the bar for engineering quality, reliability and accountability
Mentoring engineers and strengthening overall team capability
Driving continuous improvement in how we build and operate systems
Your toolkit:
A track record of delivering high-impact, complex systems in production environments
Strong systems thinking and architectural judgement
The ability to navigate ambiguity and turn complexity into clear, actionable plans
Confidence making data-informed technical decisions with long-term consequences in mind
Experience influencing beyond your immediate team
A deep customer focus and a bias toward measurable outcomes
A genuine commitment to engineering quality and raising standards
Experience mentoring others and amplifying team impact
Ownership beyond your own output
We’re intentionally technology agnostic. What matters to us is how you think, how you solve problems and the scale of what you’ve built.
Our engineering culture:
- Customer impact over unnecessary complexity
- Team success over individual heroics
- Operational ownership, not just feature delivery
- Continuous improvement through honest feedback
