Job Description
World Class Defence Organisation is currently looking to recruit a number of Mechanical Systems Engineer / Architects on an initial 6 month contract. The department can have the role based from either the Stevenage, Bristol or Bolton sites.
This role would suit a candidate who comes from a strong background of working as a Mechanical Design Engineer, Mechanical Systems Engineer, Mechanical Architect or has experience of Mechanical Systems Architecture. A defence / aerospace background is ideal but not essential. DOORS experiencewould be great.
Rate:£60.00 per hour
Overtime Rate: Hours worked over the standard 37 hours per week, will be paid at time and a quarter
Location: Stevenage, Bolton or Bristol depending on your preference
Hybrid / Remote working: 3-4 days onsite needed. Will be 5 days onsite to begin with due to training needs
Duration: 6 Months with very likely extension. Contracts are often ongoing and long-term thereafter.
IR35 status: Inside IR35 (Umbrella)
Interview process: One stage video interview
Mechanical Systems Engineer / Architect Job Description:
We have an opportunity for an experienced Mechanical Architect to join the team. This exciting role is to gather and manage the missile mechanical architecture requirements to achieve missile performance, on time and on cost and overall layout vs compliance. This involves providing justification of the design and co-ordinate the verification evidence of missile performance to support certification.
Responsibilities:
The role is responsible for the delivery of the missile mechanical architecture requirements and typical responsibilities include:
