Full Stack Engineer - Decision Tech Product Team

Hybrid in London, UK

We’re looking for a Full Stack Engineer to join our Decision Tech Product Team. We’d like you to be a part of the technical evolution of iwoca’s loan-offer generation systems. This role is critical in allowing us to offer flexible loan options and provide a great product experience to hundreds of thousands of businesses. 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.

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 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.

You’d join a product team of five people consisting of data scientists, strategy analysts and software engineers, all aiming to improve our area of the funnel.

As a full-stack engineer in one of our product engineering teams, you’ll work closely with our tech and product strategy leads to provide critical input related to our technical needs and solutions. While there is some front-end work to be done, the majority of your work will be back-end.

• 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.

• Implement new customer offer display interfaces:
  Develop and maintain user interfaces that allow customers to interact with and customise their loan offers. This includes building and integrating features and tools that maximise the utility of our products.

• 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.

Essential:

• Proficiency in Python with a strong background in back-end engineering.

• Experience designing, building, and managing relational databases

• Experience designing, building, and maintaining API endpoints.

• Confidence working across the full stack, including front-end development in React/Type Script, with a desire to learn new technologies

• Strong communication skills, with the ability to translate business needs into clear, effective technical solutions

Bonus:

• Experience with Django and PostgreSQL

• Experience with design software, such as Figma

• Understanding of Dev Ops practices, including containerisation and CI/CD

• A strong numerical or technical background, with a degree in maths, physics, computer science, engineering, or relevant industry experience

We expect to pay from £65,000 - £80,000 for this role. But, we’re open-minded, so definitely include your salary goals with your application. We routinely benchmark salaries against market rates, and run quarterly salary and…
