Dolfin is an early-stage London fintech and member of Balderton's Launched programme building an agentic financial ops API for SMB platforms. They enable fintechs and banks to embed AI-native agents for invoicing, billing, and expenses directly into their products, moving beyond simple copilots to production-ready automation.
As a Software Engineer at Dolfin, you will bridge the gap between core product development and customer implementation. Splitting your time equally between shipping full-stack features and leading technical integrations, you'll ensure real SMBs go live on the platform. You’ll build reliable, AI-native financial infrastructure that handles high-stakes money movement.
Location: London, UK
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.
