Inside the High-Tech World of Abbott’s Donegal Diabetes Care Division: A Day in the Life of Controls Engineer Michael Cawley

In the heart of Ireland’s northwest, where the Atlantic breeze meets cutting-edge innovation, Michael Cawley is revolutionizing diabetes care through technology. As a controls engineer at Abbott’s Diabetes Care division in Donegal, Cawley isn’t just working on the production of FreeStyle Libre continuous glucose monitors—he’s using them himself as part of his Type 1 diabetes treatment.

“I enjoy solving problems and helping improve the technology that supports people living with diabetes,” Cawley shares with SiliconRepublic.com, highlighting the deeply personal connection he has to his work.

The 8 AM Rush: Where Precision Meets Purpose

Cawley’s day begins at 8 AM sharp on-site, diving straight into what he calls the “nerve center” of diabetes technology production. The sensor print line department, where he works, represents the critical first step in manufacturing sensors that are literally life-changing for millions worldwide.

At 8:15 AM, the engineering and operations meeting kicks off—a brief but intense session where priorities are aligned and tasks are assigned. “It’s a great way to keep everyone on the same page and ensure critical actions are tackled first,” Cawley explains.

No Two Days Are the Same in the World of Medical Device Manufacturing

The beauty—and challenge—of Cawley’s role lies in its unpredictability. One moment he might be troubleshooting equipment that’s gone offline, the next he’s programming PLCs (Programmable Logic Controllers) or fine-tuning vision systems for IQA (In-Process Quality Assurance) qualifications.

“I might be troubleshooting equipment, programming PLCs, fine-tuning vision or motor control systems for IQA qualifications, or collaborating on process improvements,” he details. “Managing workload is a balance of structured planning and reactive problem-solving.”

The ultimate mission? “Keep the line running smoothly and safely while driving continuous improvement, because every sensor we produce plays a role in improving lives.”

From Concept to Reality: The Projects That Matter

Cawley’s project portfolio reads like a roadmap of modern manufacturing innovation. From troubleshooting and optimizing existing systems to commissioning entirely new production lines, his work spans the full spectrum of industrial engineering.

“We’re also implementing new approaches to accommodate upcoming products, which adds an exciting layer of innovation,” he reveals. The stakes couldn’t be higher—these projects are critical for guaranteeing the required supply of devices that make a real difference to diabetes care worldwide.

The Unexpected Skills That Make the Difference

While technical prowess forms the foundation of Cawley’s expertise—PLC programming, motor control, vision system configuration—he’s discovered that success in his role demands much more.

“What surprised me most was how much I’d need skills beyond engineering,” Cawley admits. Project management, stakeholder communication, and balancing priorities under pressure have become daily necessities. “I also didn’t expect to spend so much time analysing data, but this is a crucial skill for driving improvements and ensuring alignment across teams.”

His diverse background proves invaluable. Previous experience as an operator, process lead, and validation engineer provided him with deep insights into manufacturing processes, quality standards, and team dynamics that he draws upon regularly.

When the Pressure’s On: Navigating the Hardest Parts of the Day

The most challenging moments come when deep technical work collides with urgent production needs. “Debugging a PLC program or analysing data in JMP requires focus, but unexpected issues on the line can come up at any moment and need immediate attention,” Cawley explains.

Switching between structured tasks and reactive problem-solving can be demanding. His strategy? “I block time for critical work where possible.” During commissioning phases, which often involve long hours and tight deadlines, clear communication with the team and setting realistic expectations become essential for keeping projects on track.

Productivity Secrets from the Front Lines

Cawley’s productivity arsenal includes some surprisingly simple yet powerful tools. “One of my biggest productivity tips is to document everything in OneNote,” he shares. In controls engineering, where multiple coding platforms are in play, good documentation provides clear information to colleagues who may need to work on the same issues later.

For data analysis and troubleshooting, JMP (statistical discovery software) is his go-to tool for quickly identifying trends and root causes, which speeds up decision-making significantly. “Another tip is to block time for deep work when possible, especially during programming or diagnostics, so I can maintain focus and deliver high quality results.”

The Art of Technical Communication

Communication in Cawley’s world is a delicate balance of technical precision and accessibility. “Most of my communication happens through Microsoft Teams for quick updates, video calls and coordinating tasks,” he explains. Email handles formal updates, including vendor communications, while face-to-face communication on the production floor remains vital for rapid problem-solving.

One of the most critical communication skills in his role is explaining complex controls issues or software updates to colleagues without technical backgrounds. “I focus on breaking down the information clearly and concisely without sounding condescending. This helps maintain trust and ensures everyone understands the impact of changes on production and quality.”

Riding the Wave of Technological Evolution

In just three years, Cawley has witnessed remarkable changes in his field. “I’ve only been in this role for three years, so I haven’t seen all the long-term changes as I’m still gaining experience,” he notes. “However, it’s clear how quickly hardware and software versions change with advances in technology.”

Even in this relatively short timeframe, he’s seen components and platforms requiring updates to keep pace with new standards and features—a testament to the rapid evolution of medical device manufacturing technology.

The Heart of the Matter: Why This Work Matters

For Cawley, the most rewarding aspect of his job is the problem-solving itself. “There’s a real sense of satisfaction in diagnosing or resolving an issue, implementing a solution, and seeing the production line run smoothly again.”

But beyond the technical satisfaction lies something deeper. As a user of the FreeStyle Libre 2 Plus sensor manufactured in Donegal, Cawley experiences firsthand the impact of his work. “Knowing that the systems I help to maintain contribute to producing devices that improve the lives of people with diabetes makes my job even more meaningful.”

This unique perspective—being both creator and consumer of the technology—infuses every aspect of his work with purpose and passion.
