Overview

At Tuza, we’re building technology that fundamentally changes how banks operate. Our platform, TuzaOS, enables banks to deploy agentic workflows that execute complex, regulated processes in a policy-controlled, auditable way. Since launch, we’ve helped leading UK banks (Worldpay, Barclaycard, and NatWest) to scale faster by serving thousands of customers more efficiently and connecting them with leading distribution partners such as MoneySuperMarket, Uswitch, and Money.co.uk.

Tuza today and tomorrow: The Intelligent Operating System for Banks, a Unified Data Infrastructure, and Built-In Governance and Explainable Intelligence to enable transparent, auditable and compliant automation at scale.

The team

Our engineering team is obsessed with our users, endlessly curious about new ways to create value, and deeply technical.

Responsibilities

• Architect and build the systems and workflows that form the backbone of our core banking platform, keeping it scalable, secure, and auditable by design.
• Spike proof-of-concepts to explore new technologies, design patterns, and product opportunities.
• Balance speed with longevity by knowing when to move fast and when to invest in scalable, maintainable and extensible foundations.
• Work closely with product, design, and data teams to turn complex, regulated banking processes into elegant, automated workflows.
• Own features end-to-end, from concept to production, with a done-is-deployed attitude.

Qualifications / You’re a great fit if

• You have at least 4+ years of experience in software engineering, and back yourself as an individual contributor.
• You're opinionated on software engineering best practices, balanced by a bias for shipping.
• You bring advanced expertise in TypeScript and feel comfortable working across the full-stack.
• You have a solid grasp of system design and can build scalable, maintainable architectures.
• You hold a high bar for craftsmanship and care deeply about what you build and how users experience it.
• You’re excited to decide for yourself what the most impactful things to work on are.
• You may have worked in a VC-backed startup, so you’re comfortable with ambiguity, autonomy, and speed.
• You’re curious about using AI to enhance your productivity and shape how teams build software.

Not a fit if

• You lack genuine curiosity about the user, the product, the technology, or the problem we’re solving.
• You struggle with ambiguity and prefer rigid structure or constant direction.
• You’re hesitant to take ownership or lead projects end-to-end.
• You’re unopinionated about what you work on or how it should be built.
• You’re not interested in the commercial, product, or broader business context behind the engineering.

What’s in it for you

• A competitive salary with generous equity.
• A hybrid working approach. We’re based out of Shoreditch office, with Monday and Thursday as core collaboration days. Other days are focus days - based wherever you work best.
• Flexible working hours. Most people arrive between 8 and 10, and leave between 6 and 7.
• Unlimited holiday with a minimum of 24 days.
• MacBook Pro, monitor, mouse and keyboard.
• £350 a year towards taking a break.
• £350 a year towards learning, development or a hobby.
• Team off-sites around the world.
• Smart and kind teammates who value collaboration.
• The occasional soundbath…
