Senior Software Engineer
Our Mission
At Ophelos, we believe in a different way to deal with debt. One that puts empathy and understanding front and centre, approaching our customers as individuals — no matter what they’re going through.
For too long, people in debt have borne the brunt of poor industry practices. Intimidating tactics, time-consuming customer service and a one-size-fits-all approach that overlooks the reasons anyone can fall into debt in the first place. Meanwhile, businesses suffer too. Poor customer experience translates to poor customer satisfaction, high churn rates, bad brand reputation and ultimately missed opportunities.
That’s why we’re taking a radically different approach. Pioneering an industry-first AI-native collections platform, we build products that help individuals clear their debts in a way that suits them, whilst providing businesses with an improved customer experience and game-changing insights into their customer base.
Since our launch in 2021, we’ve worked with some of the UK’s leading companies, including Octopus, Scottish Power and Philips — helping millions of people move toward a more stable, debt-free future. In 2023, we were acquired by Intrum, Europe’s biggest credit management service and have begun the next phase in our growth — expansion into 17 European markets over the next two years.
Senior Software Engineer (Full Stack)
We are seeking an enthusiastic and ambitious Senior Software Engineer with a keen eye for quality to join our growing Engineering function. You will be joining our Payments squad, responsible for building out our cross-market flexible Payments capability. This is a team which has recently transitioned to being “LLM-first” in their working style, so you would be joining at a critical moment to shape our ways of working and our approaches to LLM-based tooling.
In this role, you’ll get to:
- Design, implement and deliver software features with full ownership from start to finish.
- Collaborate as part of a close & multi-disciplinary team. Your work will have meaningful and measurable impact on our organisation and products
- Own business-critical components and ensure their stability and maintainability
- Mentor other members of the team to ensure technical excellence and continuously raise the bar when it comes to engineering standards.
- Share your ideas with the team and build products that make an incredibly impactful difference to society and people’s lives
Ophelos Tech is an AI-first technical organisation, and effective use of LLMs are central to how our Engineers work. Claude Code, Codex, and OpenSpec are critical tools in our toolbox. The right person for this role should be excited and motivated to work in this AI-first world.
Stack-wise, we run TypeScript, Python, and Ruby at various levels in our stack – for this role we are really seeking a polyglot Software Engineer for whom specific implementation language is not critical. Elsewhere in our stack, we make use of:
- the FastAPI web application framework.
- PostgreSQL (via PlanetScale) as our application-level data backend
- Databricks as our “data lakehouse”.
- Temporal for workflow automation.
- Claude Code for LLM-first Software Engineering.
- OpenSpec for LLM-powered specification-driven development.
- Datadog for monitoring & observability.
- AWS & Kubernetes as our cloud-based infrastructure platform.
- Ruby & Rails powering our legacy application.
- TigerBeetle to power our financial ledger.
Ophelos Tech operates hybrid working, and believes face-to-face working time is essential for planning and alignment.
Our teams spend two days each week working in-person from our comfortable office near Liverpool Street in London.
