• Technical expertise within your discipline and ability to collaborate across engineering disciplines.
• Excellent analytical, problem-solving, communication, and interpersonal skills.
• Ability to manage multiple projects and priorities effectively.

What’s in it for you?

• Competitive salary from £52,000 to £62,000 per annum, depending on experience.
• 26 days holiday, increasing to 30 with service, plus bank holidays.
