Back End Engineer - Repeats

The Repeats team is an autonomous team responsible for the lending strategy and digital user experience of our recurring customers. They own all the product decisions that occur after a customer has taken their first funding. This includes the user journey for repeat customers, the eligibility and documents requirements for repeat applications, the offer terms (such as offered amount or pricing), among other things. The team is cross-functional, with a data scientist and a strategy analyst on top of back-end and front-end developers. They work collaboratively to design new product features together and ensure these are delivered through an intuitive, high-performing digital experience., As a Back-end Engineer on the Repeats team, you will design, build, and own the high-performance services that execute our lending strategy. You will get to:

• Exercise autonomy: Own projects end to end, from scoping and design to execution. Lead multi-engineer projects, coordinating with analysts, product managers, and other stakeholders.
• Drive impact: Enhance our offerings to meet the needs of repeat customers, improving their access to tailored lending solutions.
• Shape our systems: Design and maintain robust, flexible, and maintainable systems to ensure scalability and fast-paced development.
• Learn through iteration: Embrace a culture of experimentation, using trial and error to uncover insights, refine approaches, and grow your technical and strategic skills.
• Apply continuous deployment: Work iteratively, supported by high test coverage, and contribute to the team's frequent deployment cycles (averaging more than once per day).
• Unlock data-driven decision-making: we use hypothesis testing and metrics such as issuance and profitability to iterate and optimise our approach.

The projects

We're striving to offer our customers a lot of flexibility, while making the product easy for them to understand and use. We're constantly testing new features and optimising existing parts of our strategy. Here are two examples of projects:

• Top-up eligibility: We're optimising when customers are able to apply for more funds when they currently have an ongoing loan with us. This will involve setting up several tests affecting a core functionality of our product. This is a great opportunity to learn about our customers' behaviour and optimise a key element of our lending strategy.
• Offer amount testing: You will help re-architect our offer strategy by building and scaling the microservice that controls offer amounts. This project involves designing and migrating business logic from our core monolith to this dedicated service, enabling the team to rapidly test how offer amounts affect customer behaviour, issuance, and loss rate.

• Experience in back-end engineering, ideally with Python.

• Proven experience leading projects end-to-end, from designing to executing a solution,

• Good understanding of business problems and communication with stakeholders.

• Experience writing comprehensive automated tests, and a high level of attention to details to ensure safe releases.

• An understanding of data analysis and statistics.

• A strong numerical or technical background, underpinned by a degree in maths, physics, computer science, engineering, or a related field.

• Experience with Django.

• Experience with relational databases (ideally PostgreSQL).
