The posting, as the company wrote it
Astranis builds advanced satellites for high orbits, expanding humanity’s reach into the solar system. Today Astranis satellites provide dedicated, secure networks to highly-sophisticated customers across the globe – large enterprises, sovereign governments, and the US military.
With five satellites on orbit and many more set to launch soon, the company is servicing a backlog of more than $1 billion of commercial contracts. Astranis is the preferred satellite communications partner for buyers with stringent requirements for uptime, data security, network visibility, and customization.
Astranis has raised over $1.2 billion from some of the world’s best investors, including Andreessen Horowitz, Baillie Gifford, Blackrock, Fidelity, Franklin Templeton, and Snowpoint, and employs a team of 500 engineers and entrepreneurs. Astranis designs, builds, and operates its satellites out of its 153,000 sq. ft. headquarters in Northern California, USA.
Senior Opto-Mechanical Engineer
As an Astranis Opto-Mechanical Design Engineer you will own the complete lifecycle of various opto-mechanical systems on our spacecraft. Whether it is incremental improvements or the introduction of a new system, you will work together with the various other teams at Astranis to make them a reality.
In addition to being a significant individual on your own, you will mentor and train junior opt-mechanical engineers on such projects. You must have a strong problem-solving background, hands-on testing skills, and preferably some experience with spacecraft and/or aerospace engineering.

Develop new opto-mechanical products from concept and detailed design through engineering drawings, vendor selection, evaluation, prototype builds and production
Design and integrate free-space optical assemblies, miniature optics, optical mounts and precision alignment mechanisms
Perform detailed tolerance analyses and tolerance stack-ups for optical and mechanical assemblies
Integrate mechanical, optical and electrical components into complex optoelectronic systems
Lead mechanical and opto-mechanical design reviews
Work closely with optical, electrical, manufacturing and other cross-functional engineering teams
Assist in recruiting, interviewing, and hiring additional teammates to our rapidly-growing team.
Requirements
B.S. or M.S in mechanical, aerospace engineering or equivalent
5+ years of opto-mechanical design experience , combining precision mechanical design with optical system integration
Experience in detailed design, development and validation of mechanical assemblies from prototype through manufacturing
Experience designing mechanical mounts, interfaces and assemblies for optical components such as lenses, mirrors, lasers/light sources, detectors, fibers or similar optical components
Experience with precision optical alignment , including active and/or passive alignment; micron or sub-micron alignment experience is highly desirable
Experience with free-space optics and miniature optical assemblies
Experience working with suppliers and/or contract manufacturers
A passion for hardware development, including working in a fast-paced environment with hands-on design and development
A motivated leader who has experience mentoring and supporting junior engineers
