Lynk’s business is to provide everywhere connectivity directly to the existing 5.2 billion mobile phone users on the planet, and to billions more who will now have a compelling reason to buy a mobile phone.
As an ADCS Engineer at Lynk, you will wear many hats in the world of electronics, hardware, and software. You will be responsible for the analysis, design, implementation, optimization and enhancement of spacecraft attitude determination and control systems for the satellites in our constellation. Some work products will include spacecraft ADCS level design, flight code and algorithm design, ADC component evaluations (e.g., sensors, actuators), ADC component design, full hardware-in-the-loop simulation of spacecraft dynamics on in lab flatsats, design of in lab test environments and set ups to support ADCS development and testing, etc. Candidates with guidance navigation and control (GNC) experience are considered a huge plus and would also be involved in GNC system design, analysis, software development, and testing. While developing lots of software and simulation capabilities, you’ll be working with hardware on the bench, and probably need to pick up a soldering gun, use an oscilloscope, and/or configure a 6-DOF simulator.
If you enjoy the challenge of wearing many hats and have a track record of creative thinking to solve unconventional problems, then we look forward to meeting you!
Because Lynk is a small company, an ADCS Engineer will straddle engineering work in the domains of electrical, mechanical, and software engineering.
