6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Contribution to Overall Equipment Effectiveness (OEE)
The measurable increase in OEE across our key operational assets directly attributable to your IoT architectural designs and deployed solutions.
Target · Measurable >5% increase in OEE within 18 months of solution deployment.

If a factory line's OEE was 70% before your IoT solution, we'd expect it to hit 73.5% or more, directly linked to reduced downtime or improved quality data.

IoT Programme Return on Investment (ROI)
The overall financial return generated by the portfolio of IoT programmes you've architected and overseen, compared to the total investment.
Target · Deliver a positive return on investment across the IoT programme portfolio within 24 months.

An IoT programme costing £1M should generate at least £1M in savings or new revenue within two years, based on your architectural choices and implementation strategy.

Platform Scalability & Cost Efficiency
How well your architectural designs allow our IoT infrastructure to grow in device count and data volume without a disproportionate increase in operational costs.
Target · Architect a solution that scales from 1,000 to 100,000 devices with less than a 10% increase in marginal operational cost per device.

If we add 10,000 new sensors, the cost per sensor for data ingestion and processing shouldn't jump significantly; your architecture should handle it gracefully.

Technical Debt Reduction & Maintainability
The extent to which your architectural decisions lead to clean, well-documented, and easily maintainable IoT systems, reducing future technical debt.
Target · Reduce critical technical debt items by 20% year-on-year, as identified in architectural reviews.

Identifying and replacing a brittle, custom-built data ingestion pipeline with a robust, off-the-shelf cloud service, reducing future maintenance effort by 30%.

Strategic Influence & Roadmap Adoption
Your ability to shape and get buy-in for the long-term IoT technical strategy across Operations and with other departments.
  • Your IoT roadmap is regularly presented to and adopted by senior leadership. Other department heads proactively seek your input on their digital transformation initiatives. You're seen as the authority on IoT strategy, not just implementation details.
Architectural Soundness & Resilience
The robustness, security, and future-proofing of the IoT architectures you design and oversee.
  • Infrequent critical system failures related to architectural flaws. Positive feedback from internal security audits. The architecture can adapt to new technologies or business requirements without major overhauls. Your designs are praised for their elegance and practicality.
Team Capability & Development
Your effectiveness in mentoring, guiding, and building the technical expertise of the IoT implementation team.
  • High retention rates within your team. Junior and mid-level team members consistently growing their skills and taking on more complex work. Your team members actively seek your guidance and feedback, seeing you as a trusted expert and mentor.
Cross-Functional Collaboration & Standardisation
How well you work with IT, Production, and other teams to create unified standards and processes for IoT deployments.
  • Formalised, agreed-upon standards for device provisioning, security, and data governance that are adopted company-wide. Smooth project handovers between your team and IT operations. Reduced 'turf wars' between IT and OT, thanks to clear architectural boundaries and collaboration frameworks.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Building & Transforming

You'll spend your days designing large-scale systems that genuinely change how we operate, seeing your architectural blueprints come to life and deliver tangible impact across our business units. It's about creating something new and better.

Leading the design of a new predictive maintenance platform that prevents critical machine failures across all our factories, moving us from reactive to proactive operations.

Strategic Impact & Influence

Your decisions will directly shape the long-term operational strategy and competitive position of the company. You'll be influencing senior leadership, setting technical direction, and seeing your vision adopted at an enterprise level.

Presenting the 3-year IoT roadmap to the executive board and securing significant investment based on your strategic foresight and architectural plan.

Solving Complex, Multi-Dimensional Problems

You thrive on tackling challenges that involve technology, people, processes, and budget constraints all at once. It's not just a technical puzzle; it's an organisational one, and you enjoy orchestrating the solution.

Designing an IoT architecture that integrates 20-year-old PLCs with a modern cloud platform, ensuring data security, scalability, and seamless integration with existing ERP systems.

What frustrates people
  • The 'IT vs. OT' turf war never truly goes away; you'll still be mediating debates about who owns what and why firewalls need to be opened.
  • Dealing with 'strategy stagnation' – brilliant architectural plans that get approved but then stall due to lack of budget follow-through or shifting executive priorities.
  • The sheer complexity of integrating disparate systems, where 80% of the effort goes into the last 20% of the problem, often involving legacy protocols and undocumented APIs.
  • The challenge of building a truly unified 'single pane of glass' dashboard that actually satisfies everyone's needs, rather than just adding another siloed view.
  • Having to constantly justify the ROI of strategic IoT investments to finance, especially when the benefits are long-term or harder to quantify directly.
What this role does not give you
  • A purely hands-on coding or implementation role; you'll be guiding and reviewing, not doing all the heavy lifting yourself.
  • A predictable, 'set it and forget it' environment; the technology, business needs, and challenges are constantly evolving.
  • A role where you can avoid organisational politics; influencing stakeholders and building consensus is a core part of the job.
  • A chance to work in a greenfield-only environment; brownfield challenges are a constant companion.

8Who you work with

This role directly shapes the operational efficiency, cost reduction, and competitive advantage we get from IoT across the entire Operations department. Your architectural decisions will impact everything from production line uptime and predictive maintenance to supply chain visibility and worker safety. Frankly, you'll be accountable for ensuring our significant investment in IoT actually pays off, directly influencing the Operations P&L and our long-term strategic capabilities.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a Principal Architect's time is precious. You should be thinking about multi-year strategies, not getting bogged down in repetitive tasks or sifting through mountains of documentation. That's where AI comes in. We're building an AI Hub specifically for our Operations team, designed to free you up to do what you do best: architecting the future.

Imagine AI as your super-smart assistant, handling the tedious bits of architectural review, strategic planning, and documentation. It won't replace your strategic brain, but it will certainly augment it, making you significantly more productive and impactful. Here's a glimpse of how you'll be using AI in this role:

AI-driven Architecture Validation

Use AI models to automatically review your proposed IoT architectures against established best practices, security standards, and scalability requirements. The AI can flag potential bottlenecks, compliance risks, or common design flaws before they become expensive problems. Think of it as an instant, highly intelligent peer review.

Strategic Forecasting & Scenario Planning

Leverage AI-powered predictive models to forecast the impact of different IoT architectural choices on OEE, operational costs, and energy consumption. Run 'what-if' scenarios to evaluate the long-term implications of platform decisions or new technology adoption, giving you data-backed insights for your strategic recommendations.

Automated Policy & Governance Drafting

Instead of starting from scratch, use a private LLM to draft initial versions of IoT governance policies, security standards, or data retention guidelines. The AI can pull from internal documents and industry best practices, giving you a solid first draft to refine, saving hours of detailed writing.

Executive Summary Generation

Feed your detailed architectural proposals, programme status reports, and technical analyses into an AI. It can then generate concise, executive-level summaries, highlighting key decisions, risks, and strategic implications, tailored for different audiences like the board or finance leadership. No more spending hours trying to condense complex information.
