Position: Senior Mechanical Simulation Engineer

Salary: £95,000 – £132,000 per annum

Job Type: Full-time | Permanent

Work location: London 

 

What We Offer:

• Lead simulation-driven development of next-generation opto-mechanical systems
• Work at the cutting edge of AI hardware and optical computing
• High ownership role with strong technical influence
• Close collaboration with mechanical, optical, electrical, and materials teams
• Opportunity to shape industry-defining technology from the ground up

Other Benefits:

• Meaningful equity & stock options
• £24,000 Living-Local Bonus (if residing within 20 minutes of the office)
• Full UK & international visa sponsorship
• Dedicated relocation funding and concierge support
• Premium BUPA medical & dental cover (MHD included)
• 25 days annual leave + UK bank holidays
• Top-tier equipment (M4 Macs, Pro upgrades for engineers)
• High-spec ergonomic workspace & noise-cancelling headphones
• Access to advanced 3D printing and rapid prototyping labs
• Chef-prepared meals when working late
• Coffee on the house at local partner cafés

Your Role Will Include:

• Lead multi-physics simulations for high-performance optical and computing systems
• Conduct advanced FEA for stress, strain, warpage, and modal analysis
• Perform thermo-optical-mechanical simulations across assembly and operation stages
• Drive substrate stack-up optimisation for mechanical stability and thermal performance
• Model ageing, creep, fatigue, and long-term reliability behaviour
• Guide material selection across ceramics, organics, ABF, and BT substrates
• Correlate simulation results with empirical testing and validation data
• Standardise and automate workflows using ANSYS, Abaqus, or COMSOL
• Define specifications with manufacturing partners and vendors
• Clearly document methodologies, assumptions, and design recommendations

What We’re Looking For:

• 10+ years’ experience in mechanical simulation and analysis
• Strong background in opto-mechanical systems, substrates, or advanced materials
• Deep expertise in multi-physics and thermo-mechanical modelling
• Proven experience with warpage control, thermal management, and reliability analysis
• Advanced proficiency in ANSYS, Abaqus, or COMSOL
• Strong understanding of material properties (CTE, modulus, thermal conductivity)
• Ability to translate complex simulation data into actionable design improvements
• Excellent communication and cross-functional collaboration skills
• Master’s degree in Mechanical Engineering, Materials Science, Physics, or similar
• PhD highly desirable

 

This is a rare, career-defining opportunity to work at the frontier of AI, optics, and advanced engineering. With top-tier compensation, equity ownership, full visa sponsorship, and the chance to help build a category-defining technology, Olix offers more than a job—it offers a legacy.
