Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Senior Back-end Engineer - Customer Operations Platform - **Company:** iwoca - **Location:** London, UK - **Experience:** Expert - **Salary:** £80,000.0 - £100,000.0 - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Business Logic, Data Architecture, Cursor (Graphical User Interface Elements), Software Debugging, Distributed Systems, Django Web Framework, Software Tools, Systems Architecture, TypeScript, Web Application Frameworks, ReactJS, Backend, Front End Software Development - **Published:** August 17, 2026 - **Apply:** https://www.adzuna.co.uk/jobs/details/5844306794 ## About the Role * Experience developing and owning shared back end services that other engineering teams contribute to and depend on - being the trusted reviewer for their contributions and shaping how they build on top of your work. * Familiarity with front-end technologies (React, TypeScript) and browser debugging. * Experience building and shaping distributed systems in complex business domains. * Ability to translate complex operational needs into technical architecture. * Strong capability using AI tools to automate routine tasks and research, enabling greater focus on complex system architecture and critical technical decision-making. * You use AI (Cursor, Claude Code or similar) in your daily flow - whether for work or for fun. You use it to blast through boilerplate and research so you can focus on the hard parts: complex architecture, rigour and high-stakes decisions. Bonus: * Commercial experience with Python frameworks like Django. * Experience with complex data architectures, including event-sourced data models. ## Description As a senior engineer you'd take whole projects end to end, work out what' s actually needed, design it, build it and look after it in production. Responsibility and Autonomy: * Take the lead on complex projects that span many systems and many stakeholders - e.g. CRM, telephony, contact, and task management * Build a strong understanding of the business context: how our ops teams actually work, how the processes you're automating are supposed to run, and what the people relying on your systems need from them. * Do the detailed technical scoping and prototyping that tells us whether an idea is feasible before it reaches the roadmap. Delivery and Collaboration * Take on complex coding and architecture problems with a high level of ambiguity and technical complexity. * Write fluent technical documents and developer tickets distilling product requirements into clear and actionable technical work. * Build relationships with key stakeholders including Operations Strategy, Credit Analysts, Account Managers, and Collections teams. Learning and Growth: * Mentor junior developers, fostering a learning environment that encourages experimentation and innovation. * Embody our growth mindset mentality by sharing new technologies and best practices within the team as well as more broadly across the company. The projects Here are some of the most recent problems we are solving: * iwocaChat. Operations staff spend a large share of their day assembling context from multiple systems before they can help a customer. iwocaChat uses Claude to answer those questions directly, so staff spend their time on the customer rather than the lookup. * Migrating the monolith. We are incrementally moving business logic out of our Django monolith into smaller, independently deployable services. Because it cuts across every domain, you'd be shaping service boundaries and ownership models that stick around long after the monolith is gone. * Inbox messaging reworking. We are replacing our third party email inbox application with an inhouse solution, utilising AI to enable operations staff to automate the actions of our most frequent customer service enquiries. ## 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) - [Do TypeScript without TypeScript](https://www.wearedevelopers.com/videos/327-do-typescript-without-typescript) - [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) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) - [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) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [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) - [Dev Digest 137 - AI'm not sure about this](https://www.wearedevelopers.com/magazine/485-dev-digest-137-ai-m-not-sure-about-this)
