Senior Software Engineer

Location: Widley

Are you an experienced Automation Software Engineer, Controls Engineer or PLC Programmer with strong hands-on experience across PLCs, robotics, HMIs and vision systems?

Do you enjoy solving complex automation problems, improving machine performance and sharing your technical knowledge with other engineers?

We're supporting a leading precision manufacturing business in Portsmouth who are looking to recruit a Senior Production Support Software Engineer to join their growing engineering team.

This is a senior, hands-on position where you'll work directly with specialist automated manufacturing equipment, taking ownership of complex software and controls issues while helping develop the technical capability of the wider team.

What's the role all about?

As the Senior Production Support Software Engineer, you'll be responsible for maintaining, improving and developing the software and control systems behind specialist automated manufacturing machinery.

You'll work across PLC, robotic, HMI and vision systems, identifying faults, improving existing software and implementing solutions that increase machine reliability and production throughput.

This isn't purely a desk-based programming position. You'll work directly with production machinery, troubleshoot complex automation issues and collaborate closely with other engineers to ensure equipment performs effectively.

As a senior member of the team, you'll also play an important role in mentoring and developing junior and mid-level engineers, sharing your knowledge and helping strengthen automation capability across the department.
