Data Engineering

London
Build the data products that make Tuza's workflows and agents industry leading

Meet our data team

Our data team is task with applying expertise in data science, data analysis, and AI engineering to understand how our users behave. Their models and insights feed into data products as well as into our wider product strategy.

They do things like:

  • Build agentic workflows that automate reasoning, data analysis, and decision-making across the business.
  • Integrate large language models and retrieval systems into data products to deliver contextual, dynamic insights in real time.
  • Play with transaction data to recognise temporal or spatial patterns.
  • Build risk insights by combining onboarding data with in-life behaviour to detect anomalies and automate interventions.
  • Design dynamic pricing models that personalise payment pricing based on business usage, risk, and segment.
  • Launch product recommendation logic that serves merchants contextual bundles at the right moment in their lifecycle.
  • Benchmark provider performance to show which of our partners are outperforming across time to board, churn, and margin.
  • Create intelligent and personalised user experiences based on customer context to increase business-product fit and reduce time to conversion.

By the end of your first sprint, you will likely have built at least one data project live in production, in use by some of the UK’s largest banks and thousands of their small business customers.

The Stack

Our data stack is modern and evolving. You'll be responsible for shaping and maturing the architecture to fit our stage and scale, as long as it sits within AWS.

Our current data platform includes:

  • Python for data modelling and analysis
  • Agentic frameworks such as LangChain and LlamaIndex
  • Airbyte to load data from external sources
  • RDS Postgres for storing product data
  • Amazon Redshift as our data warehouse
  • DBT for data modelling, transformation, and testing
  • Metabase for internal reporting, deep dives, and data exports

In case you're interested, our software stack includes React, TypeScript, GraphQL, REST, Express, Relay, Prisma, Redis, Postgres, AWS, Styled Components, and Storybook.

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 a solid knowledge of data science and AI engineering.
  • You work end-to-end and can design, engineer and maintain our data stack.
  • You've worked with agentic frameworks (LangChain, LlamaIndex) in the past.
  • You’ve had exposure to a previous high-performance environment - this may be another startup backed by tier 1 investors, but it could just as easily be a competitive hobby.
  • You know what good engineering practices look like - we need you to work with our engineering team to integrate your insights into our products.
  • You find the extensive breadth and ambiguous nature of this role inspiring.

You're a bad fit if

  • You lack genuine interest in data - we want you to be obsessed.
  • You’re unopinionated on what you work on - we want you to care.
  • You’re not interested in the commercial context or wider business strategy.

Our ways of working

At Tuza, we've founded our working principles with influences from Basecamp’s product development framework, Shape Up, Matt Lerner's Growth Levers and How to Find Them, and Melissa Perri's Escaping The Build Trap.

The crux is that we like to focus on the ‘why’. Why are we building this product, or feature, and what outcome are we hoping for?

We value focusing on our customers, output over input, and experiment more than we optimise. We outline how we work in more detail here. This isn't static: we're constantly aiming to improve based on team feedback.

What's in it for you

  • A competitive salary with generous equity.
  • A hybrid working approach. We're based out of our Shoreditch office.
  • Flexible working hours.
  • Unlimited holiday with a minimum of 24 days.
  • Smart and kind teammates - leave your ego at the door.
  • The occasional soundbath…

Meet Tuza

We believe passionately that the most impactful AI deployments in enterprise are deployed by the people who built them. We’re looking for team members who will collaborate with the world's largest banks to solve mission critical problems.

Today, banks spend $100B+ per year on outsourcing business process. The result is customers spend weeks engaging with manual processes, while banks constrain their ability to grow. Outsourcing is a pill that is increasingly expensive, slow, and fragile. We've raised $7m from the backers behind Klarna, Spotify and Stripe to build the agents that solve this.

At Tuza, we're building AI-native automation for financial services. Our platform and agents create end to end customer lifecycle automation that reduce manual process by up to 90%.

The Problem

The Solution

Tuza is building the exchange for card payments.

But what does that really mean?

It means we're providing independent businesses access to the most competitive card machine rates, while partnering with banks to improve the outdated pricing processes. These inefficiencies have reduced transparency for banks and driven up fees for businesses - we're here to change that.

Tackling a problem this big requires a group of smart, ambitious, and curious individuals. Our team is made up of people with autonomy and ownership over their role, supported by the ideas and innovation of the wider team.

We're a diverse bunch, made up of engineering, design, marketing, operations and sales, with one shared goal - to create something big.

Roles at Tuza
