The company

Fast, flexible finance empowers small businesses to manage their cash flow better and seize opportunities - making their business and the economy stronger as a whole. At iwoca, we do just that. We help businesses get the funds they need, when they need it, often within minutes. We’ve already made several billion in funding available to more than 100,000 businesses since we launched in 2012, and positioned ourselves as a leading Fintech in Europe.

Our mission is to finance one million businesses. We’ll get there by continuing to make our finance ever more relevant and accessible to more businesses by combining cutting-edge technology, data science, and a 5-star customer service.

The team

The Fraud team is a new team within iwoca, and owns iwoca’s strategy and tech systems against fraud. The team balances robust fraud prevention with an exceptional customer experience and strong conversion rates. The team is growing, and currently consists of a principal full-stack engineer and a Team Lead.

We need a full-stack engineer to join the growing Fraud team, to help significantly restructure and simplify iwoca’s fraud systems. This is a high-growth role, with a view that you will grow to take on technical leadership of the team.

Ownership and influence

• Design and build iwoca’s new fraud system, to achieve a balance between fraud prevention and customer experience.
• Take ownership of the solutions that feed into this system, covering both in-built capabilities and third-party integrations.
• Use data to identify opportunities and measure improvements to our systems and processes.

Collaboration

• Work with product, analytics and strategy team members to ensure technical solutions align with iwoca’s overall fraud strategy.
• Collaborate with engineers within other parts of iwoca, such as our Operations, Customer Funnel, and Credit Risk teams, to drive fraud tech changes forwards.

Growth and progression

• Progress to becoming the team’s technical lead within 6-9 months.

The requirements

Essential:

• Back-end development experience, ideally with Python.
• Front-end development experience with TypeScript.
• Experience with Django, PostgreSQL, and designing, building, and managing relational databases.
• Excellent communication skills, with the ability to translate business needs into effective technical solutions.

Bonus:

• Experience working with third-party integrations.
• React framework experience.
• A strong numerical academic background, i.e. maths, physics, computer science, engineering, or similar.
• An understanding of data analysis and statistics.

The salary

We expect to pay from £60,000 - £70,000 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 performance and salary reviews.

The culture

At iwoca, we prioritise a culture of learning, growth, and support, and invest in the professional development of our team members. We value thought and skill diversity, and encourage you to explore new areas of interest to help us innovate and improve our products and services.

• Offices in London, Leeds, Frankfurt, and Berlin with plenty of drinks and snacks.
• Events and clubs, like bingo, comedy nights, yoga classes, football, etc.

• Medical insurance from Vitality, including discounted gym membership.
• A private GP service (separate from Vitality) for you, your partner, and your dependents.
• 25 days’ holiday, an extra day off for your birthday, the option to buy or sell an additional five days of annual leave, and unlimited unpaid leave.
• A one-month, fully paid sabbatical after four years.
• Instant access to external counselling and therapy sessions for team members that need emotional or mental health support.
