How you will make an Impact (Job Summary)
SPX is a diverse team of unique individuals who all make an impact. As an experienced and pragmatic Principal Software Architect you will define and drive the technical vision for our evolving software ecosystem.

This role is responsible for shaping how our hardware and firmware platforms integrate with cloud, mobile, and desktop applications, ensuring we continue to evolve toward a coherent, scalable, and maintainable architecture across the organisation.

The Principal Software Architect will serve as the focal point for architectural direction, system design principles, and technology strategy. Working closely with domain leads, the Software Program Manager, and the Global Software Manager, the successful candidate will ensure architectural intent translates into practical, deliverable outcomes.

This position combines strategic leadership with hands-on technical validation. The ideal candidate will be capable of both defining long-term architectural direction and validating ideas through lightweight prototyping and experimentation where required.

• Firmware / device layer
• Cloud platform
• Mobile and desktop applications Own:
• Target system architecture and design principles
• System boundaries and interaction models
• Integration patterns across domains Ensure architecture supports:
• Scalability and maintainability
• Product evolution across multiple device variants
• Alignment with long-term business and product strategy 2.

Current State Assessment & Transformation Roadmap Build a clear understanding of the current software landscape and define a path forward.

Deliver:
• Documented view of current architecture and technology stack
• Identified gaps, risks, and constraints
• Target architecture aligned to business and product direction
• Migration and/or retirement proposals for legacy systems Ensure transition plans are:
• Realistic and incremental
• Aligned with delivery priorities
• Understood by engineering and product teams
