About The Job
Industrial automation is evolving rapidly and we're looking for someone who wants to help shape what's next, not simply maintain what's come before.
We are looking for a Principal OT Engineer to lead the design and delivery of modern Operational Technology (OT) architectures, using Ignition as the primary platform, Python to develop intelligent solutions, and MQTT/Sparkplug B to seamlessly connect data from the edge to the cloud.
This is far more than a traditional SCADA engineering role. You'll act as the technical authority for complex automation projects, leading architectural decisions, mentoring engineers, and working closely with clients to deliver innovative, future-focused solutions. Remaining hands-on with emerging technologies, you'll play a pivotal role in advancing both our engineering capability and the next generation of industrial automation.
If you're passionate about modern OT, enjoy solving complex technical challenges, and want to influence the future of industrial automation, this is an opportunity to make a lasting impact while working with cutting-edge technologies and a team committed to engineering excellence.
WHO ARE ITI GROUP?
Through our 50 year history, ITI Group has combined the skills, experience, and knowledge of many recognised and respected industry names to become a leading partner for industry. We develop and integrate digital transformation solutions for Energy, Nuclear and Industrial manufacturing sectors. We advance safe, secure and sustainable operations through the innovative use of technology.
You’ll be joining a global brand with locations across the UK, Europe and North America. Our people work together with clients to solve problems, unlock the potential of the connected world, and create solutions that deliver value.
At the heart of ITI Group is a complete commitment to innovation and transformation. Our people are practical, insightful and dynamic, with a personal approach. We are dedicated to working in partnership with our colleagues, leaders and customers, and developing a culture that allows us to inspire, and deliver a safe, sustainable future where people shine.

SUMMARY OF ROLE AND RESPONSIBILITIES
- Lead the design of complex solution architectures from Ignition Perspective applications to containerised edge deployments and MQTT/Sparkplug B data pipelines connecting the plant floor to the enterprise.
- Act as the technical authority on Ignition and industrial IoT architectures, guiding the Engineering team and Project Managers through the tough decisions.
- Investigate and pilot new OT technologies; containerisation, Unified Namespace architectures, cloud-edge integration and bring them back to the team.
- Own technical estimates and client conversations for new opportunities, working closely with Sales and Project Managers.
- Champion modern engineering standards: version control, CI/CD pipelines and automated testing across every project stage.
- Lead, mentor and grow an engineering team – owning their development, performance and day-to-day direction.
- Get hands-on with commissioning and troubleshooting at client sites when the team needs you there.
