Job Description
We are looking for a driven ADCS Engineer with experience in developing, simulating, and implementing attitude determination and control algorithms for nanosatellites or CubeSats. You will be responsible for designing control logic, simulating satellite dynamics, integrating sensors and actuators, and ensuring the satellite maintains desired orientation in orbit.
Requirements
Key Responsibilities:
- Design and simulate attitude control algorithms.
- Develop attitude estimation filters such as EKF, TRIAD, QUEST using sensor data.
- Select and integrate ADCS hardware including Magnetorquers, reaction wheels, gyros, star trackers, sun sensors.
- Model spacecraft dynamics and validate control system performance using MATLAB/Simulink, Python, or C++.
- Implement ADCS firmware on an onboard flight computer.
- Support HIL and SIL testing for flight readiness.
- Coordinate with mechanical, thermal, and mission teams to define attitude modes.
- Analyze in-orbit telemetry and tune control parameters post-launch for improved pointing accuracy.
Required Skills & Qualifications:
- B.E./B.Tech or M.E./M.Tech in Aerospace, Electronics, Controls, Mechatronics, or related field.
- 2–5 years of experience working on ADCS systems for satellites.
- Strong understanding of orbital mechanics, control theory, and spacecraft attitude dynamics.
- Proficiency in tools such as MATLAB/Simulink, Python, or C/C++
- Familiar with embedded system implementation and communication protocols.
- Experience with inertial sensors and actuator control.
Nice to Have (Preferred):
- Hands-on experience with reaction wheel control or magnetorquer boards.
- Knowledge of Kalman filters and high-fidelity spacecraft modeling.
- Familiarity with STK, GMAT, or Orekit for orbit and attitude visualization.
- Experience working on spaceflight missions with in-orbit validation of ADCS.
Additional Requirements:
- Passion for space, satellites, and ground segment technologies.
- Self-driven and willing to learn continuously.
- Willingness to relocate as per the needs of the mission or organization.
Not sure if you meet every requirement?
If you’re passionate about ADCS and have hands-on experience, even if you don’t meet every single qualification listed, we strongly encourage you to apply. We value talent, learning ability, and real-world experience just as much as titles or checklists.
