Job Description
As a Software Engineer at Dolfin, you will bridge the gap between core product development and customer implementation.

Location

Why this role is remarkable
- Join a fast‑moving team in the Balderton Launched programme with a multi‑million pound pipeline and signed platform clients already in production.
- Work at the cutting edge of AI and fintech, building agentic workflows that handle real‑world financial operations rather than simple demos or copilots.
- High‑autonomy environment where you partner directly with founders to shape the engineering culture, product architecture, and technical roadmap from day one.
What You Will Do
- Design and build event‑driven, multi‑tenant backend systems and frontend interfaces for the core agentic financial operations platform.
- Lead customer integrations end‑to‑end, serving as the primary technical architect on calls to unblock partner engineering teams and ship fixes.
- Deploy production‑grade LLM workflows into financial environments, ensuring absolute correctness, auditability, and reliability for high‑stakes money movement.
The ideal candidate
- Possesses 2–4 years of experience shipping production software with a deep background in fintech API infrastructure, payments, or open banking.
- Demonstrates strong full‑stack proficiency, comfortable owning both backend architecture and frontend implementation while operating in a fast‑paced, unstructured environment.
- Displays a customer‑centric engineering mindset, capable of translating integration friction into product improvements and building trust with external technical teams.
