Senior Electro-Mechanical Engineering Technician (Optical)

K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by over $1 billion in total funding from leading investors including Altimeter Capital, ICONIQ, Kleiner Perkins, Lightspeed Venture Partners, Redpoint Ventures, and T. Rowe Price — and with over $1 billion in signed contracts across commercial and US government customers, we're mass-producing the highest-power satellite platforms ever built for missions from LEO to deep space. The rise of heavy-lift launch vehicles is shifting the industry from an era of mass constraint to one of mass abundance, and we believe this new era demands a fundamentally different class of spacecraft. Engineered to survive the harshest radiation environments and to fully capitalize on today's and tomorrow's massive rockets, K2 satellites deliver unmatched capability at constellation scale and across multiple orbits. With multiple launches in 2027 and plans to scale to 100 satellites a year, we're Building Bigger — helping develop the solar system and build toward a Kardashev Type II (K2) civilization. If you are a motivated individual who thrives in a fast-paced environment and you're excited about contributing to the success of a high-growth Series D-funded company, we'd love for you to apply. The Role   You will support the fabrication and assembly of optical subsystems, production tooling, and generate hardware performance records. This role will support manufacturing and development of the K2 Mega-class satellite and future generations of the spacecraft. The ideal candidate possesses advanced mechanical skills,  will seek ownership over quality and reliability, is meticulous and tenacious,  and is familiar with the handling and testing of optical components. A strong background in optical manufacturing, R&D and testing is desired.   Responsibilities   Partner directly with design engineering throughout the hardware development and pre-production stages, supporting component assembly and validation testing   Perform precision inspection, cleaning, bonding, and troubleshooting of optical components to exacting tolerances   Operate precision tooling including microscopes, adhesive dispensing systems, UV curing equipment, and optical alignment tooling to support next-generation hardware   Execute work from verbal instructions, engineering drawings, and technical procedures with minimal supervision, adapting quickly as designs evolve   Build, align, integrate, test, and maintain optical systems — including delicate freespace optics and mechanics, thermal management hardware, and fiber optic assemblies    Own test setup, execution, and data reporting, ensuring accuracy and traceability across all builds    Maintain ground support equipment performance and calibration   Champion laser safety and cleanliness standards on the production floor, holding yourself and the team accountable to the highest standards   Practice 5S principles of organizing and sustaining an efficient and presentable workspace    Thrive in fast paced/ all-hands-on-deck production environment, jumping in wherever needed to hit mission timelines     Qualifications   5+ years of experience assembling, integrating, and testing optical hardware or adjacent hardware (ie: technical hardware utilizing optical sensors, fibers, sources, or high-resolution mechanisms)   Proficiency with computers and ability to use MS Office and shop floor management software   Demonstrate high level of ownership and problem-solving abilities   Demonstrate ability to learn, adapt and work independently    Demonstrate dexterity and ability to handle delicate objects in a dynamic lab environment    Demonstrate ability to communicate and prioritize team success   Experience working with FOD, ESD sensitive hardware, and clean room requirements   Experience with optical cleanliness or similar (ie: use of lab solvents like HPLC IPA, Acetone, Methanol and delicate cleaning methods)   Nice to Have   Experience with optical metrology equipment such as interferometers, autocollimators, laser trackers, theodolites, power meters   Experience with handling optical fiber and optical fiber technology such as fiber splicers, polarization components, fiber polishing & cleaning, fiber cleaving   Experience with lasers and laser safety   Experience with optical wavefront optimization through alignment   Ability to troubleshoot or develop production code in LabVIEW, Python, MATLAB or similar   Able to read mechanical and engineering drawings and interpret tolerances (including GD&T)   Operate machining equipment such as a lathe, mill, drill press   Experience working with engineering in development and production environments   Strong communication skills with ability to provide feedback to engineering teams to improve tooling processes and part design   Willingness to provide constructive feedback to the engineering and production teams to improve tooling designs, processes and parts   Able to stay organized with strong attention to detail   Additional Requirements   Willing to work overtime and weekends as needed   Must be able to stoop, bend, crawl, and maneuver in tight spaces   Must be able to lift and carry parts or equipment up to 25 lbs. unassisted   Compensation and Benefits:   Hourly pay range for this non-exempt role is $40 - $45 + equity in the company   Compensation will be based on several factors including, but not limited to: knowledge and skills, education, and experience level   Comprehensive benefits package including paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many other perks   If you don’t meet 100% of the preferred skills and experience, we encourage you to still apply!
