Job Description

Nixor are proud to be supporting a Leading Financial Services provider at the very start of building out a brand new Architecture practice. They are removing reliance on 3rd parties & bringing all capability in-house, so this is therefore an opportunity to be a senior member of a whole new growing division.

This is a domain specific role, so Financial Services experience is required, but this can be from either Industry side or Consultancy.

About the Role

As a Lead / Principal Architect, you'll take technical ownership of a critical business domain. You’ll guide the transition from legacy systems to a modern, cloud-, microservices architecture, with a specific focus on solutions that serve the business unit you are aligned too.

The Principle Architect is responsible for owning the architecture roadmap end-to-end within their domain — from strategy to implementation. Unlike in some organisations where architects may focus more on governance or high-level oversight, my client expects their architects to be technically involved and closely aligned with delivery teams.

However, this is a Leadership role. You will be managing a team, bringing stakeholders on a journey and owning strategic direction.

Key responsibilities include:

End-to-end ownership of the domain architecture, including technical decisions, roadmap definition, and implementation oversight. Hands-on engagement, including decisions on infrastructure, patterns, configuration, observability, and cost scaling. Stakeholder engagement, building relationships that allow delivery teams to interface independently while maintaining architectural integrity. Guidance and leadership, steering solution direction, ensuring scalability, and aligning designs with strategic goals. Prioritisation of tactical vs. strategic work, ideally by evaluating trade-offs and alignment with the target state — though not all candidates demonstrated this understanding.

Why Join?

Be in at the beginning of building a brand new team. Huge Impact as you will own the technical landscape for your domain. Clear direction, no third-party constraints, and full in-house ownership Minimal politics, strong alignment from board to tech team Tech-first and user-centric approach from day one

We’re looking for experienced Senior Architects with:

Proven experience in solutions architecture within a heavily regulated industry. A strong track record of modernising legacy systems into scalable, microservices-based platforms Deep knowledge of design patterns, cloud- practices, and architectural governance Experience of managing and running a team of Architects. Ability to still dig into the technical detail of P1 incidents.

This is a hands-on leadership role — ideal for someone who wants to shape strategy but also stay close to the technology.

Interested?

This is your chance to join one of the UK’s most ambitious architecture transformations — with the scale of a large enterprise and the agility of a start-up team.
