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 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.

This role offers the chance to make a meaningful, lasting impact during a transformative journey, with full support and endorsement from the board.

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 point of contact for your business unit

Why Join?

The Director of Architecture joined 6 months ago because:

"I've never worked anywhere where you can make such an impact so quickly. We're building this team from the top down, and these Principal Architects will be the first hires—I want to create a high-performing architectural function, and the business fully supports me."

Additional benefits include:

• A large change budget with access to significant funds
• Minimal internal politics due to prior stakeholder alignment
• Focus on delivering user-centric designs from day one

Candidate Profile

We’re seeking experienced Architects with:

• A strong background in solutions architecture (Applications, Cloud, Security, etc.)
• Experience modernizing legacy systems into microservices-based architectures
• Deep knowledge of design patterns, cloud infrastructure, and application security
• Prior experience in the Insurance Industry, ideally Life Insurance
• Effective communication with technical and non-technical stakeholders

This is a hands-on leadership role combining strategic influence with daily architectural contributions. You will work alongside Business Architects to guide your domain's technical direction.
