You’d be helping design, build and maintain a set of orchestrated services that will serve our primary business needs and core product functionality as we scale.

The company

Small businesses move fast. Opportunities often don’t wait, and cash flow pressures can appear overnight. To keep going, and growing, SMEs need finance that’s as flexible and responsive as they are.

That's why we built iwoca. Our smart technology, data science and five-star customer service ensures business owners can act with the speed, confidence and control they need, exactly when it's needed.

We’ve already cleared the way for 100,000 businesses with more than £4 billion in funding. Our passionate team is driven to help even more SMEs succeed, through access to better finance and other services that make running a business easier. Our ultimate mission is to support one million SMEs in their defining moments, creating lasting impact for the communities and economies they drive.

The team

The team own and optimise the systems that generate loan offers for new customers - including pricing, credit limits, and other offer terms - and choose which offers to present to the customer.

The role

As a Back End Engineer, you will design, build, and own the high-performance services that execute our lending strategy. You will get to:

• 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

• Optimise and deploy live decision models: Collaborate with data scientists to reduce the runtime of optimisation models, ensuring timely decisions and low-load times for customers. This involves deep dives into performance bottlenecks and implementing efficient solutions.

• Redesign offer generation architecture: Evolve and consolidate our offer generation services, leveraging your expertise to refactor and simplify the existing architecture. This investment will enhance scalability and maintainability, reflecting iwoca's growth and modern approach to business loans.

• Develop robust analytics infrastructure: Build and enhance data models and pipelines to ensure accurate and timely data collections. This will involve designing and implementing data solutions that empower the strategy and analytics team to conduct split tests and make data-driven decisions.
