About this opportunity and L3Harris UK

From 11 UK sites, our team of nearly 1,000 people delivers unique capabilities across space, air, land, sea and cyber for military, security and commercial customers across the UK and worldwide.

In the land domain, our T7 and T4 multi-mission robots deliver next-generation remote capabilities and uncompromised performance. We design and manufacture world-leading land force protection systems, cyber and electromagnetic activities (CEMA), electronic warfare (EW) and encryption capabilities. Our cyber capabilities provide an information advantage in the fields of kinetic conflict, cyber warfare, force protection and counterterrorism.

We're looking for experienced Technical Project Managers to join our growing Engineering team and play a pivotal role in delivering some of the UK's most advanced Electronic Warfare and Cyber Security capabilities.

This is a unique opportunity to take ownership of complex engineering programmes from concept through to delivery, working at the intersection of technical leadership and project execution. You'll lead multidisciplinary teams of engineers, helping shape solutions that support critical defence and security missions while ensuring programmes are delivered on time, within budget and to the highest technical standards.

Success in this role requires more than strong project management capability. We're seeking individuals with a solid engineering background who can engage confidently with technical challenges, understand the realities of engineering development and earn the respect of highly skilled engineering teams. While we're open to candidates from a range of engineering disciplines—including systems, software, electronics, hardware, mechanical or related fields—the ability to combine technical depth with programme leadership is essential.

As a newly evolving role within the business, you'll have the opportunity to influence both engineering outcomes and project delivery practices, acting as the vital link between technical teams, customers and senior stakeholders. Whether you identify as an Engineering Project Manager, Project Engineer or Technical Programme Manager, this role offers the chance to combine engineering expertise with programme leadership in a fast-paced and highly collaborative environment.

A few of our employee benefits are:

• Half day finish on a Friday
• 25 days holiday per year (plus bank holidays), increasing with long service and with the opportunity to buy/sell up to 5 days
• Private medical insurance with optional family cover
• Pension scheme of up to 8% employer contribution
• Life Assurance 4x salary (flexible up to 10x)
• Group income protection
• Flexible opt-in extras such as a health care cash plan, dental insurance, gym membership, critical illness cover and cycle to work scheme
• Employee Family Assistance Program providing mental health and wellbeing support
• Professional membership reimbursement (discretionary)

What the role will involve

The responsibilities of your role will include the following:

• Managing a complex development programme involving a cross functional engineering team
• Leading key design reviews in accordance with process (e.g. SRR, PDR, CDR etc)
• Estimating, scheduling and tracking progress amongst the engineering team and reporting earned value metrics including CPI, SPI, ETC, BCWS, BCWP and ACWP
• Managing risks and planning mitigation strategies to minimise technical risk
• Interfacing with and presenting to key stakeholders including customers, regulatory authorities and, internally, with senior managers
• Guiding a new product development through the systems engineering lifecycle ensuring compliance against internal processes and legal and safety standards
• Contributing to the generation of technical proposals, bids and supporting internal review, governance and sign-off.
• Guiding and mentoring engineers to support skills development within the wider team.
