Senior Structural and Mechanical Systems Engineer

Senior Structural and Mechanical Systems Engineer, Job Ref: 2123

Reports To Mechanical Design & Analysis Functional Manager

Responsible For

SSTL is seeking a motivated and dynamic Senior Structural and Mechanical Systems Engineer to help shape and influence current and future flight spacecraft structures and mechanical systems. As part of the mechanical team, you will play a vital role in spacecraft layout, structural developments, and the analysis of new structural systems. You will oversee structural and mechanical sub-systems from concept through to ground verification testing and flight, working closely with mechanical design and principal engineers. The role involves a combination of structural design, analysis, and testing activities, as well as supporting the development of spacecraft mechanical systems to ensure reliable operation in demanding environments. This work focuses on delivering innovative and robust solutions for spacecraft structures and mechanical systems

Key Tasks

• Technical Leadership: Serve as the Technical Lead for structural and mechanical system design for spacecraft structures.

• Work Package Management: Develop and maintain schedules and budgets for mechanical and structural Work Packages, reporting budget and schedule deviations and managing risks.

• Risk Management: Identify, monitor, and mitigate structural and mechanical systems risks.

• Requirement Management: Flow down customer requirements to subsystem and hardware levels, ensuring compliance and validation.

• Development Plans: Define, organise, and implement structural development, qualification, and validation plans.

• Finite Element Analysis (FEA) and Analytical Modelling: Develop and manage analytical models for structures and subsystems using FEA, performing static, dynamic, and quasi-static analyses to validate numerical results with test data and determine structural margins of safety. Refine numerical models to ensure alignment with experimental data.

• Environmental Specifications: Derive environmental envelope specifications from launch documentation, analytical results, and test data.

• Mass Properties Management: Manage structural and system mass properties including mass, centre of gravity and moments/ products of inertia.

• Test Campaigns: Define, organise, and lead structural testing (vibration, static, acoustic, shock, and mass properties)

• Documentation: Maintain design/analysis logs, document analysis activities, and write test and compliance reports.

• Customer Engagement: Present work at internal and external reviews, ensuring effective communication and reporting.
