Vacuum Process Engineer

Description:

Aquark Technologies is a start-up with a vision to create disruptive technology in sensing and quantum computing by delivering the world’s most portable, scalable and high performing miniaturised cold atom systems.

As a Vacuum Process Engineer, you will be responsible for translating vacuum concepts into robust, repeatable, and scalable fabrication processes for miniaturised vacuum systems and miniaturised vapour cells. You will design and implement bonding, sealing, and assembly techniques, ensuring they are reproducible and suitable for future manufacturing.

This role sits within a research programme (funded by UKRI FLF) to transform traditional vacuum hardware into compact, robust, and scalable platforms, enabling a shift from bespoke laboratory setups to manufacturable, off-the-shelf solutions. Working at the intersection of vacuum science, materials engineering, and microfabrication within a fast-paced startup environment, you will collaborate with a driven team to deliver innovative, high-impact technologies while contributing to the growth of a dynamic and evolving company.

Responsibilities:

• Develop miniaturised vapour and UHV cells using microfabrication techniques, including integration of alkali sources and hermetic sealing processes.

• Fabricate chambers using MEMS techniques, including testing innovations with active pumping and passive pumping.

• Support, as needed, the modelling of sealing and fabrication processes, ensuring simulation inputs reflect realistic geometries, materials, and manufacturing constraints.

• Train other staff as needed.

Qualifications:

Essential

• Degree (BSc/MSc/PhD or equivalent experience) in Engineering, Physics, Materials Science, or a related field

• Experience with vacuum system design, assembly, and operation (high vacuum or UHV)

• Strong mechanical aptitude with hands-on experience in building, assembling, or prototyping mechanical systems.

• Strong understanding of vacuum-compatible materials and sealing techniques

Desirable

• Experience with microfabrication or precision manufacturing processes (e.g. bonding, MEMS, wafer-level techniques)

• Knowledge of hermetic sealing methods (e.g. anodic bonding, thermocompression, brazing, laser welding)

• Proficiency in data analysis, modelling, or automation desired.

• Familiarity with alkali vapour cells

• Ability to work independently, problem-solve, demonstrate initiative, and engage in continuous learning to adopt new skills.

• Ability to work collaboratively across disciplines in a fast-paced R&D environment

Renumeration:

• Total salary and bonus up to: £46,000 to £72,000 (salary dependent on experience)

  • Base salary: £39,428.57 to £61,714.29

  • Company Milestone Bonus Scheme, up to: £6,571.43 to £10,285.71 (2x £3,285.71 to £5,142.86 payments).

• Full earnings pension contribution:

  • Employer contribution – 3%

  • Employee contribution – 4%

  • Relief at source – 1%

Other Benefits:

• Private Medical Insurance.

• Group Life Insurance.

• Employee Assistance Programme.

• 26 Days of holiday + Public holidays.

• Flexibility around core hours.

• Regular company outings, team building and training opportunities.

• Electric Vehicle Salary Sacrifice.

• Encouraged learning to continue professional development.
