Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Back End Engineer - Partner Flow Team - **Company:** iwoca - **Location:** London, UK (Remote available) - **Salary:** £60,000.0 - £85,000.0 - **Contract:** Permanent contract - **Skills:** A/B Testing, Application Programming Interfaces (APIs), Artificial Intelligence, Code Review, Relational Databases, DevOps, Programming Tools, Python (Programming Language), PostgreSQL, TypeScript, ReactJS, Snowflake, Backend, Front End Software Development - **Published:** September 20, 2026 - **Apply:** https://startup.jobs/back-end-engineer-partner-flow-iwoca-co-uk-10128165 ## About the Role Essential: * Experience designing and building scalable back-end systems, ideally in Python. * Experience working with relational databases, ideally PostgreSQL, with an understanding of performance and maintainability considerations. * Experience building and maintaining APIs that are easy to use, reliable, and well-documented. * Experience managing projects end to end, from understanding business problems to designing and delivering technical solutions. * Pragmatism in balancing delivery speed with long-term system health. * Clear, concise written and verbal communication, focusing on outcomes and impact. * A genuine team player: you support your teammates, share knowledge, and care about the team's success as much as your own. * AI fluency. Experience using AI coding tools to accelerate real delivery, and a genuine interest in getting better at it - with a pragmatic sense of where it adds value and where it doesn't. Bonus: * Front-end development experience, particularly with React and Typescript. * Experience with DevOps practices, including containerisation and CI/CD pipelines. * Experience with experimentation (e.g. A/B tests or RCTs) or using data to drive product decisions. * Working knowledge of modern data tooling - ideally Snowflake and dbt - used to build analytical or reporting pipelines. ## Description The Partner Flow team builds new features and optimises existing flows to provide the best possible experience for iwoca's partners and the customers they refer to us. The team's responsibilities include: * Continually improving our Lending API and other developer tools, so that partners can integrate with iwoca quickly and easily. * Adding new functionality to facilitate deeper integrations and ensure iwoca is the best embedded finance provider on the market. * Improving the conversion rate of customers who come to us through partners - streamlining the journey, running RCTs (randomised control trials) and building models alongside our embedded data scientist to find what works. The team is made up of three engineers, a data scientist plus a team lead, working closely with an internal team of commercial stakeholders. This role is one of two new engineering hires as we grow the team to meet our ambition. Partner Flow is remote/hybrid-friendly, meeting up for team days in the office once or twice a month, but not on a fixed schedule. They work in an Agile fashion with two-week sprints and a daily standup. The role You'll work on challenging projects all over iwoca's codebase - anywhere there are improvements to be made for partners and partner-referred customers. You'll be encouraged to bring your own ideas and take responsibility for areas of functionality. Autonomy: * Own features and projects from scoping and design through to production. * Collaborate with other engineers to meet the team's goals, whilst being trusted to define your own solutions and work independently on your part of the problem. * Design and maintain robust, flexible, and maintainable systems to ensure scalability and fast-paced development. Impact: * Deliver new functionality critical to onboarding important new partners. * Run experiments (RCTs) and optimise the funnel to measurably improve how partner-referred customers convert. * Leave code, docs, and processes in better shape than you found them. Purpose and product thinking: * Work on systems that genuinely help businesses get the funding they need. * Collaborate with our partners and internal stakeholders to design effective solutions. * Use data to make decisions, uncover insights, and refine strategies. AI: * We're pushing hard on AI-assisted development. Engineers here write clear technical specs, let skills and agents implement boiler-plate, and hold a high bar on code review - the person, not the model, is accountable for what merges. We expect AI output to be validated for correctness, performance and security like any other change. * We give the team unlimited tokens across all models and expect people to experiment. ## Related Videos - [Inside Bitpanda's Tech Stack: Scaling a European Fintech Leader - Markus Dorner](https://www.wearedevelopers.com/videos/1979-inside-bitpanda-s-tech-stack-scaling-a-european-fintech-leader-markus-dorner) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Recruitment Reinvented: Bold strategies and the $10K signing incentive](https://www.wearedevelopers.com/videos/1068-recruitment-reinvented-bold-strategies-and-the-10k-signing-incentive) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Best Companies to work for in London: Top 25 Companies in 2023](https://www.wearedevelopers.com/magazine/187-best-companies-to-work-for-in-london-top-25-companies-in-2023) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london)
