Astral Systems is a pioneering fusion technology company developing compact fusion reactors and neutron source systems for medical, industrial and research applications.
We are growing our engineering team and are looking for an experienced Mechanical Design Engineer to help design and develop next-generation compact fusion devices. This is a hands-on, technically varied role covering concept design, CAD modelling, detailed drawings, supplier engagement, manufacturing support and final assembly.
This is an excellent opportunity for someone who enjoys precision engineering, advanced technology and seeing their designs move from concept through to real-world manufacture and assembly.
What you’ll be doing
You will design precision mechanical components and assemblies for compact fusion reactor systems, producing detailed CAD models, engineering drawings, BOMs and technical documentation.
You will work closely with R&D, engineering, manufacturing and external suppliers to develop new reactor components and subsystems. The role will also involve supporting RFQs, liaising with machining and fabrication partners, reviewing manufacturability, resolving technical issues and ensuring parts meet design intent.
You will contribute to design reviews, support tolerance analysis and material selection, and help ensure designs meet the required safety, reliability and performance standards.
What we’re looking for
We are looking for someone with:
- At least 5 years’ experience in mechanical design engineering.
- Strong 3D CAD skills, ideally Solid Edge or equivalent.
- Experience designing complex mechanical parts and assemblies for manufacture.
- Strong knowledge of engineering drawings, GD&T and tolerancing.
- Experience working with suppliers, fabricators or machining partners.
- A good understanding of machining, fabrication and assembly processes.
- Strong organisational and communication skills.
- The ability to manage multiple design tasks and work independently when needed.
Experience in any of the following would be particularly useful:
- Precision engineering.
- High-vacuum systems.
- Scientific instrumentation.
- Aerospace, defence, medical devices, semiconductor, nuclear, fusion or other advanced engineering environments.
- Teamcenter or other revision control / lifecycle management software.
About you
You are proactive, practical and detail-oriented. You enjoy solving technical problems, producing high-quality design work and collaborating with others to turn ideas into manufactured components.
You will be comfortable working in a fast-moving technical environment where priorities can evolve, and you will be motivated by the opportunity to contribute to a pioneering fusion technology company at an exciting stage of growth.
What we offer
- The opportunity to work on cutting-edge fusion and neutron source technologies.
- A supportive and ambitious engineering environment.
- Competitive salary and benefits.
- Training and development opportunities.
- Potential progression into senior engineering or technical leadership roles.
Applicants should submit a CV. Candidates may be asked to provide examples of previous design work during the recruitment process, where possible. We fully understand that some previous work may be confidential.
