About the role:

What if we could offer you the chance to work as part of a team of like-minded Engineers on the next generation of Cyber Security and Electronic Defence technology?

At L3Harris, in our Intelligence & Cyber International (ICI) division, we work closely with UK Government and Security Agencies to develop and build cutting edge solutions to combat the threats faced by the public and private sectors on a daily basis. These threats grow more sophisticated every day and we have to stay one step ahead by continually evolving our tech to ‘prevent the event’.

A position at L3Harris will mean getting to innovate, architect, develop and see ideas become a reality over the full lifecycle of a product. In addition, there are opportunities to work on fully funded bleeding edge research and development projects – where things really get interesting!

We are looking for a Systems Engineer to join us and take a key role in the Systems Engineering activities for systems engineering development programmes, either working as part of a team of systems engineers, or possibly leading a small team of junior engineers for those with more experience.

Our primary ICI sites are in Gloucestershire and Hampshire and Engineers make up over 50% of our workforce. If this sounds like your type of thing then we are keen to hear from you!

Responsibilities of the role:

  • The development of complex Cyber Security or Electronic Warfare Systems and in some cases acting in a lead role for a sub-system or a phase of the development (e.g. Verification).
  • Contribute to the generation of technical proposals, bids and presentations.
  • Lead the implementation of design solutions liaising closely with Software, Electronic design and Mechanical design teams.
  • Drive the test and qualification strategy for solutions and sub-systems.
  • Opportunities to participate in trials, customer demonstrations and onsite acceptance testing in a range of countries worldwide.
  • Opportunities to progress to Leadership Roles within Systems Engineering or other areas of the company

Your Experience

  • Experience of engineering development projects through most parts of the systems lifecycle from concept definition through to handover to the customer.
  • Experience of requirements capture, decomposition and establishing verification strategies for embedded systems.
  • Experience of Model based systems engineering using SysML
  • Experience of working closely with low level design teams in electronic design, mechanical design and software.
  • Some experience of team leadership and/or mentoring of more junior engineering staff.
  • Relevant industry experience in either the Defence, Aerospace or other complex embedded environments.
  • Some domain experience in at least one of either Cyber Security or RF (such as EW, Communications or Radar) is preferable.

Your Skills

  • Ability to capture, manage and decompose system requirements for complex EW or Cyber Security systems.
  • Ability to understand, describe, document and present an abstracted view of a complex system through a variety of media.
  • Ability to develop Verification strategies for complex embedded systems.
  • Skilled at using DOORS or other similar Requirements Management Tools.
  • Understanding of Systems Functional Safety through conducting hazard analysis or safety case generation for complex systems to IEC 61508 or other similar standards.
  • Understanding of design for reliability, human factors and security.
  • Awareness of software design and development, FPGA and Electronic design (digital and RF).
  • Good understanding of Project Management and Engineering Management through producing realistic estimates, managing risk and monitoring progress to meet tight timescales.
  • Excellent Microsoft Office Skills.
