Senior Systems Engineer

About the Role

As a Senior Systems Engineer, you will apply Systems Engineering principles across the full engineering lifecycle, from requirements definition through design, integration, verification, customer acceptance, in-service support, and system disposal. You will leverage your expertise to develop system and sub-system level solutions that meet stakeholder needs and regulatory requirements.

The role involves resolving complex engineering challenges, providing technical leadership, and ensuring successful system integration and delivery. Working collaboratively within multidisciplinary teams, you will drive coherent system design, support risk management, and contribute to continuous improvement, ensuring high-quality, efficient, and compliant engineering outcomes across a range of project scenarios.

Core Duties

• Apply Systems Engineering Principles: Implement ISO 15288 across the full lifecycle—from requirements definition through integration, acceptance, support, and disposal.
• Requirements Management: Decompose and manage system and sub-system requirements using approved tools (e.g., IBM DOORS Next).
• System Architecture & Design: Perform system design decomposition, interface definition, and maintain architectural models in tools like CATIA Magic (Cameo).
• Integration & Testing: Plan and execute system integration and testing, contributing to acceptance strategies and compliance verification.
• Technical Documentation & Reviews: Produce technical reports, presentations, and conduct reviews to ensure adherence to specifications and standards.
• Technical Leadership & Guidance: Work independently under limited direction, resolve engineering issues, and provide guidance to the immediate team.
• Maintain Contemporary Practices: Stay current with Model-Based Engineering, digital threads, cybersecurity, and safety procedures.

Essential Skills

• Demonstrate an understanding of engineering principles and approaches underpinning design and development activities, with the capability for systems thinking and applying holistic approaches to complex problems.
• Demonstrate understanding, knowledge, and experience of Systems Engineering with a focus on software-based product development, including knowledge of appropriate Systems Engineering and Software Engineering standards (e.g., ISO 15288 and ISO 12207 respectively).
• Experience of working with large scale complex system designs.
• Experience of multiple phases of an engineering lifecycle and good knowledge of lifecycle models (e.g., Waterfall, Agile) and associated tools (e.g., JIRA).
• Ability to present both technical and non-technical information in a formal setting.
