## About the Role

Cloud Computing, Customer Relations, Reinsurance, Data Analysis, Product Development, Brokerage, Artificial Intelligence (AI), Application Programming Interface (API), User Interface/Experience (UI/UX), Software as a Service (SaaS), You are a pragmatic, hands-on engineer who enjoys a fast-moving, greenfield environment and wants to work across both traditional and AI-native development. Ideally you will bring:

 * Experience: 10+ years of professional software engineering experience, with a track record of shipping and supporting production systems end to end. Experience in insurance, reinsurance or wider financial services is a plus, but not essential.
 * Backend: Strong programming skills in C#/.NET or Python, with solid API design and strong SQL.
 * Frontend: Practical experience building modern user interfaces with React or Angular and TypeScript.
 * Cloud & DevOps: Hands-on experience with Azure, CI/CD tooling such as Azure DevOps or GitHub Actions, and infrastructure-as-code (Terraform).
 * Standards & Security: Experience building to architectural standards and applying common patterns such as microservices, event-driven and API-led design, together with a strong grounding in security patterns (OAuth 2.0, OIDC, Entra ID, RBAC) and secure coding practices.
 * Data: Comfortable working with relational databases and data-heavy application features, with strong SQL and an eye for query performance.
 * AI Development: Experience building with LLMs and AI-enabled solutions, or a clear appetite to learn. Familiarity with agentic patterns, prompt design and evaluation is a significant advantage.
 * Engineering Craft: Fluency in test-driven development and automated testing, an eye for maintainable design, and good judgement about when to keep things simple.
 * Communication: Ability to work closely with product stakeholders and delivery partners, and to explain technical trade-offs clearly.

## Description

* Build Across the Stack: Design, build and ship features end to end, from APIs and services through to responsive, accessible user interfaces.
 * Cloud Native Delivery: Develop and run cloud-native applications on Microsoft Azure, using PaaS services, containers and infrastructure-as-code.
 * Data-Driven Features: Consume data through APIs and services to surface it in usable, performant ways for brokers and analysts.
 * AI-Enabled Development: Build AI-enabled product features using patterns such as retrieval-augmented generation, tool and API integration, evaluation and human-in-the-loop design.
 * AI-Assisted Engineering: Use AI-assisted engineering tools such as Claude Code or Claude Cowork as part of your day-to-day workflow, and help the wider team adopt them well.
 * Integration: Integrate with external market platforms, carrier and client systems, and vendor SaaS products using API-first and event-driven patterns.
 * Quality & Security: Practise test-driven development and write secure, maintainable code, applying established security patterns including authentication and authorisation (Entra ID, OAuth 2.0), data protection and privacy from the start.
 * Collaboration: Build to the agreed architectural standards and help shape them, contributing to design discussions, reviewing code from in-house and partner engineers, and mentoring others across a greenfield estate.
