Spacecraft GNC Engineer

Job Type: Full Time
Job Location: Hyderabad

XDLINX Labs is looking to hire a seasoned spacecraft GNC engineer to work on a closely integrated team who will drive the design of the GNC system, including hardware and software, to meet the position, attitude, knowledge and stability requirements of our bus.
You will have the opportunity to work alongside a brilliant and passionate team of engineers working on the architecture, simulation, and controls of electromechanical systems for the world’s most cutting- edge satellites.
As such, we have an intense culture of curiosity, hunger, and results. If you want a typical 9-5 job, this is not the place for you.
You do not need to meet 100% of the preferred qualifications to be considered. We encourage anyone who meets the basic qualifications and is interested in the role to apply – we are looking for enthusiastic, dedicated people to join our team, and want the opportunity to talk to you!
