Principal Systems Engineer - Detectors

We are seeking an experienced Systems Engineer or Scientist with a strong electronics background to join our growing Detectors Area of Business. In this pivotal role, you will apply your expertise to deliver cutting-edge Electro-optic/InfraRed (EO/IR) capabilities across our Detector products.

Based at our dedicated site in Southampton, this permanent position offers the chance to work on exciting, challenging, and complex projects within a diverse product portfolio of EO/IR technologies. You will play a crucial role in bridging the gap between theoretical possibilities and practical implementation, working on programmes at various stages of their development lifecycle.

Your Impact

As a Systems Engineer, you will be instrumental in integrating various engineering and technology strands to create high-performance systems. Your typical responsibilities will include:

  • Conducting applied research to explore new technologies and concepts.
  • Leading requirements capture, definition, development, modelling, manufacture, test, and verification of EO/IR technologies.
  • Applying and improving systems engineering processes throughout the full lifecycle.
  • Collaborating with integrated project teams to design, build, and deliver EO/IR equipment.

Success in this role requires a passion for systems thinking, experience in forming and leading high-performing teams, and the ability to influence stakeholders. You will thrive in dynamic environments, demonstrate resilience under pressure, and be adept at making quick, informed decisions while setting a clear technical vision.

We understand the importance of work-life balance and offer flexible working arrangements, combining home and on-site working to deliver effective results.

What You'll Bring

We are looking for individuals with an electronics background and proven domain experience in EO/IR technologies. Key attributes include:

  • Acting as the focal point for systems engineering governance on projects.
  • Proficiency in requirements capture and management, system definition and development, modelling and analysis, and verification and validation.
  • Experience applying systems engineering across the full engineering lifecycle.
  • Experience working in product development teams to deliver engineering artefacts successfully.
  • Proven ability to manage and collaborate with internal and external stakeholders.
  • Strong decision-making skills within high complexity, dynamic environments.
  • Excellent communication and interpersonal skills, with the ability to build trust and respect across different levels.
  • Motivation, tenacity, and determination to deliver results.

Desirable experience and skills include a PhD, EngD, or postgraduate degree in electro-optics, experience with Model Based Design (MBD) tools and methodologies, proficiency with modelling tools (e.g., Mathcad, MATLAB, Simulink), experience with data acquisition tools (e.g., LabView), and familiarity with requirement management tools (e.g., DOORS, Polarion, Jama). Even if you don't meet all these criteria, we encourage you to apply if you have a positive attitude and a willingness to learn.
