Principal Engineer

Principal Engineer | Financial Services | London | Permanent | Hybrid | up to £150k

I'm working on an exciting opportunity for a Principal Engineer to build new digital fintech products from the ground up (Greenfield).

This is a genuinely hands-on Principal role - you'll lead an engineering squad, shape architecture, make key technical decisions, mentor engineers and stay hands on engineering digital products.

Required:

7-8+ years' software engineering experience, with experience leading as a principal, staff level or tech lead.
Strong system design & technical leadership
Full-stack experience
Key Technologies: Java/Spring Boot, React/TypeScript and React Native, Azure (AWS or GCP is fine), Kubernetes, Terraform & CI/CD
APIs, microservices & event-driven architecture.
Production ownership & modern engineering practices.
Experience using AI - integrated into the SDLC.

The environment is seriously modern: Java, React/TypeScript, React Native, AKS, Kafka, Temporal, Databricks, Terraform, ArgoCD/GitOps, Azure AI Foundry & more.

We're open to exceptional engineers from Banking, Financial Services and other regulated environments (a strong fit from a SaaS, technology, e-commerce will also be considered). If you're a Principal, Staff or Lead Engineer who wants to build new greenfield digital fintech products - I'd love to speak with you.
