Senior Full-Stack Developer

We’re looking for a high-agency, tech-obsessed software engineer to work across our full stack, identify the biggest technical levers for impact, and turn ideas into products that users love.

Welcome

Thanks for investing the time to consider joining Tuza.

When joining a company at the early stages of its growth story, there's often more than meets the eye. This is our opportunity to help you understand why your next role should be with us.

Tuza today

At Tuza, we’re building technology that fundamentally changes how banks operate.

We’ve raised $7 million from leading investors (Northzone, Connect Ventures, and TriplePoint) to build agentic process automation for banks.

Our platform, TuzaOS, enables banks to deploy generic 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 through serving thousands of customers more efficiently and connecting them with leading distribution partners such as MoneySuperMarket, USwitch, and Money.co.uk.

Tuza tomorrow

Our vision is to be the intelligent operating system for banks; a system that doesn’t just automate tasks, but makes and executes decisions across the organisation.

We’re building the next generation of agentic banking infrastructure, where agentic workflows power every process across the entire customer lifecycle, with embedded auditability, explainability, privacy, and security.

Our values

We don’t know exactly who the right person for the job is, but we have an idea:

• Obsessed: Is obsessed with technicalities.
• Curious: Comfortable exploring novel solutions to find value.
• Technical: Understands systems deeply and how to build scalable, reliable and secure solutions.
• Product-led: Makes product decisions that solve real user pain.
• Done it before: Has experience building a data function at a high-performing startup.
• End-to-end: Takes ownership of an outcome end-to-end.

What you’ll do

Build solid foundations

• 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.

Collaborate and deliver

• 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.

Keep the bar high

• Drive technical excellence by setting the standard for speed, quality, and craft through code, PR reviews, and knowledge sharing.
• Continuously improve our engineering approach by actively engaging in retrospectives and contributing ideas to elevate the team.

How we build

Our stack includes React, TypeScript, GraphQL, REST, Express, Relay, Prisma, Redis, Postgres, AWS and Styled Components.

We like to experiment with different technologies and libraries, particularly when building proof of concepts. Make your case, and we’ll consider expanding our tech stack.

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 have strong opinions 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’ve 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.

You’re a bad fit if…

• You lack genuine curiosity about the user, the product, the technology, or the problem we’re solving - we want people who are obsessed.
• 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 with generous equity.
• A hybrid working approach. We're based out of our Shoreditch office, with Monday and Thursday as core collaboration days. The remaining 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 (2025 took us to Switzerland and Morocco).
• Smart and kind teammates - leave your ego at the door.
• The occasional soundbath…
