## About the Role

Essential:

 * Backend engineering. You've designed and built backend systems that run in production, ideally in Python, Django and PostgreSQL. You've modelled their data with performance and maintenance in mind.
 * Frontend engineering. You've built and maintained user interfaces in production, ideally in TypeScript and React.
 * Ownership. You've taken features end to end, and kept them working once people relied on them.
 * Trade-offs. You've weighed delivery speed against the long-term health of a system, and can explain what you chose and why.
 * AI leverage. You've built agentic workflows, or used AI to scale your engineering output beyond what you could deliver alone. You judge when to use it and when not to.
 * Communication. You write and speak clearly, directly, and concisely. You adapt technical detail to your audience.

## Description

As a full-stack engineer in Broker Terms, you'll make changes across iwoca's codebase wherever they'd improve an offer. Most of it is backend - the code that calculates each offer's terms - with some frontend on the UI where brokers see them.

You'll own features and projects from scoping and design through to production, and choose how to build them. You'll help decide what goes on the team's roadmap. You'll learn from the team's experienced engineers, and from the people who price broker offers.

The team is light on process - a daily stand-up, a weekly meeting and regular retrospectives - and you'll have a say in how it works. Brokers see your changes in the Introducer Portal, and A/B tests show you which ones raised Customer Lifetime Value. Your work helps businesses get the funding they need.

Live project examples:

 * Model-based pricing. Developing the systems that let a model set bespoke pricing for each customer.
 * No-fee test. Testing how the product performs without drawdown fees, and how that changes the way customers repay.
 * Loan durations. Building longer-duration Flexi-Loans with flexible repayments.
 * Offer display. Improving how offers appear to brokers and customers - a better journey, and easier testing for the team's data scientists.
 * Commission systems. Upgrading iwoca's broker commission systems., * DevOps. You've used containers and CI/CD pipelines to deploy your code.
 * Experimentation. You've worked on A/B tests or other experiments, and used the results to decide what to build next.
 * Product thinking. You've found the business need behind a feature request, and planned the technical work to meet it.
 * Financial services. You've worked on lending, payments or pricing systems.
