Opto-Mechanical Engineer

Pleasanton, CA, US, CA

Full Time

Mid Level

About the Role

Bright Silicon Technologies (BST) is replacing vulnerable RF links and bulky mechanical gimbals with solid-state optical solutions. We are defining a new era in lasercoms, going from single-point static links to multi-point agile networks. Our flagship product, OCTANE (Optical Communication Terminal for Advanced NEtworking), is an un-jammable, RF-silent free-space optical terminal delivering secure, high-bandwidth data transport across airborne platforms and ground vehicles and stations, enabling dense mesh networks on high-mobility platforms.

We’re looking for a mechanical engineer who combines precision optomechanical design experience with a hands-on approach to building and integrating optical systems. You’ll own key optomechanical assemblies within the terminal, select optical components, and design robust mounting systems for a range of operating environments. This is an opportunity to help deploy the next generation of optical MEMS technology.

What you’ll do

Own the design and development of precision optomechanical mounts and assemblies for the OCTANE terminal.
Model thermal behavior and its effects on optical alignment to develop designs with predictable, repeatable performance across operating conditions.
Select and source optical components in collaboration with the optical team and suppliers to meet system performance and environmental requirements.
Apply design-for-manufacturability principles and perform tolerance stack-up analyses for precision optomechanical assemblies.
Build, align, test, and refine optomechanical assemblies, using measured results to improve optical performance and robustness for field operation.
Integrate custom optomechanical assemblies into the communications terminal and troubleshoot issues at subsystem interfaces.
Collaborate with optical, mechanical, electronics, software, production, and product teams to translate system requirements into subsystem designs and deliver integrated optical systems.
Prepare engineering drawings, assembly and alignment procedures, and technical documentation for internal use and external release.

What we’re looking for

A bachelor’s degree in Mechanical Engineering, Optomechanical Engineering, Optical Engineering, Physics, or a related field.
At least three years of relevant experience. Industry work and substantial research experience both count.
Experience designing precision optomechanical systems and mechanisms that require accurate, stable alignment.
Familiarity with optical terminology, components and coatings, alignment methods, and free-space optical architectures.
Proficiency with 3D CAD software for mechanical design; SolidWorks preferred.
A proactive approach to identifying technical risks, managing dependencies, and taking ownership of engineering problems.
A systems perspective and the attention to detail needed to resolve precision design and integration challenges.
U.S. Person status (U.S. citizen, lawful permanent resident, or protected individual), as the role involves CUI and ITAR material.

Nice to have

A master’s or doctoral degree in a related field.
Experience designing, building, and validating custom optomechanical assemblies for demanding operating environments.
Familiarity with aerospace design practices and applicable regulatory requirements.
Experience with optical modeling software; Zemax preferred.
Experience performing thermal and structural analyses of precision optomechanical systems.
Programming experience with MATLAB, C, Python, or similar tools for engineering analysis or test automation.

Don't meet every single requirement? Studies have shown that women and people of color are less likely to apply to jobs unless they meet every single qualification. At BST we are dedicated to building a diverse, inclusive and authentic workplace, so if you're excited about this role but your past experience doesn't align perfectly with every qualification in the job description, we encourage you to apply anyway. You may be just the right candidate for this or other roles.

Why BST

Own the precision design and hands-on integration that turn optical hardware into a reliable communications system.
Collaborate with a small team whose work spans precision mechanisms, MEMS, optics, electronics, and software. Bring your expertise and build depth in neighboring disciplines.
Take meaningful technical ownership in an engineer-led company with competitive compensation, equity, and a sustainable approach to work.
