Job Description:

Nixor is seeking Principal/Lead Architects with Life Insurance / Assurance industry knowledge to join a newly formed architecture team for the UK's largest Mutual Pensions company. This is a rare opportunity to shape the future of their technology landscape as they transition from legacy architecture to a modern, microservices-based architecture.

About the Role

As a Lead Architect, you will own your domain, overseeing applications, cloud infrastructure, and services. You will help transform a legacy "spaghetti" architecture into a modern microservices architecture, starting a transformative journey supported by the company.

Key Responsibilities

• Provide technical oversight across your domain
• Collaborate with the board and senior stakeholders
• Lead the transition from monolithic to microservices architecture
• Define standards for application development, security, and observability
• Mentor junior architects and technical teams
• Serve as the technical contact for your business unit

Why Join?

The Director of Architecture joined 6 months ago for impactful work. The team is being built from the top down, with Principal Architects as the first hires, aiming to create a high-performing architectural function.

• Significant change budget available
• Minimal internal politics, stakeholder alignment complete
• Focus on delivering user-centric designs from day one

We’re seeking experienced Architects with:

• Strong background in solutions architecture (Applications, Cloud, Security)
• Experience modernizing legacy systems into microservices
• Knowledge of design patterns, cloud infrastructure, and security
• Prior experience in the Insurance Industry (Life Insurance preferred)
• Effective communication with technical and non-technical stakeholders

These roles combine strategic influence with hands-on architectural work, working alongside Business Architects to guide technical direction.
