Principal Software Architect

SPX Technologies builds innovative HVAC and Detection and Measurement solutions. Through its RiSE talent development framework, the company supports employees’ development. As part of Detection and Measurement, Radiodetection leads the design and development of equipment and software used by utility companies to protect underground infrastructure networks.

As an experienced and pragmatic Principal Software Architect you will define and drive the technical vision for our evolving software ecosystem, shaping how our hardware and firmware platforms integrate with cloud, mobile, and desktop applications. 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, you will ensure architectural intent translates into practical, deliverable outcomes. The position combines strategic leadership with hands‑on technical validation, defining long‑term architectural direction and validating ideas via lightweight prototyping and experimentation where required.

Job Responsibilities

• Architecture Vision: 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, incremental, aligned with delivery priorities, and understood by engineering and product teams.
• Cross‑Domain Alignment: escalated conflicts go to the Global Software Manager.

Success Measures

• Clear, adopted target architecture across domains.
• Reduced integration issues and late‑stage surprises.
• Consistent and aligned technology choices.
• Improved system coherence across firmware, cloud, and applications.
• Visible reduction in architectural ambiguity.
• Progress on legacy system simplification.

What Good Looks Like

• Architectural decisions are understood, adopted, and followed.
• Teams build in alignment rather than diverging.
• Trade‑offs are explicit and well managed.
• The architect is visible, engaged, and proactive.
• The role accelerates delivery rather than slows it down.

What we are looking for

Required Experience

• 15+ years of software engineering experience, with significant time in architectural roles.
• Proven designing distributed systems across cloud and application layers.
• Strong experience with at least one major cloud platform (Azure, AWS, or GCP), ideally across multiple.
• Experience integrating hardware or embedded systems with cloud‑based platforms.
• Strong understanding of modern software architecture patterns and best practices.
• Demonstrated ability to influence technical direction across multiple teams.
• Excellent communication skills across both technical and non‑technical audiences.

Preferred Experience, Knowledge, Skills, and Abilities

• Experience in hardware‑software or IoT environments.
• Exposure to mobile and SDK‑based architectures.
• Experience modernising or migrating legacy systems.
• Familiarity with AI‑assisted development approaches.
• Track record of delivering pragmatic, implementable architecture (not just conceptual design).
