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 help shape the future of their technology landscape as they transition from a legacy, "spaghetti" architecture to a modern, microservices-based architecture over the coming years.
About the Role
As a Lead Architect, you will take full ownership of your domain, overseeing applications, cloud infrastructure, and services. This is a brand new team inheriting a legacy "spaghetti" architecture, with the remit and funding to transform it into a modern Micro-services Architecture.
This role is at the start of a transformative journey, offering the chance to make a significant, lasting impact.
The initial value stream mapping has been completed, and the transformation has full endorsement from the board. With a clear vision of the target state, no third-party dependencies, and all work done in-house, this is an exciting and well-supported initiative.
Key Responsibilities
* Provide technical oversight across your assigned domain
* Work closely with the board and other senior stakeholders
* Lead the architectural transition from a complex monolithic system to a modern microservices architecture
* Define and implement standard patterns and practices for application development, security, observability, and more
* Mentor and coach junior architects and technical teams
* Act as the technical point of contact for your business unit
Why Join?
The Director of Architecture joined 6 months ago, stating:
"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. The business is fully supporting me."
They also have:
* A large change budget with significant access
* Minimal internal politics – stakeholder alignment already done
* Opportunity to focus on delivering user-centric, meaningful designs from day one
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 (Life Insurance ideally)
* Effective communication with technical and non-technical stakeholders
These roles combine strategic influence with hands-on leadership, working alongside Business Architects and guiding technical direction within your domain.
