ADCS Engineer

Key Responsibilities:

• Design and simulate attitude control algorithms for nanosatellites.
  
• Develop attitude estimation filters such as EKF, TRIAD, QUEST using sensor data.
  
• Select, size, and integrate ADCS hardware including magnetorquers, reaction wheels, gyros, star trackers, and sun sensors.
  
• Model spacecraft dynamics and validate control system performance using MATLAB/Simulink, Python, or C++.
  
• Implement ADCS firmware on onboard flight computers.
  
• Support HIL (hardware-in-the-loop) and SIL (software-in-the-loop) testing for flight readiness.
  
• Perform

  FMECA (Failure Modes, Effects, and Criticality Analysis)

  to ensure ADCS reliability and robustness.
• Coordinate with mechanical, thermal, and mission teams to define attitude modes and constraints.
  
• Work with procurement to identify, evaluate, and source ADCS components and sensors.
  
• Prepare and maintain detailed

  documentation

  for ADCS design, simulation, testing, and flight operations.
• 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.
  
• 25 years of experience working on ADCS systems for satellites.
  
• Strong understanding of orbital mechanics, control theory, and spacecraft attitude dynamics.
  
• Proficiency in MATLAB/Simulink, Python, or C/C++.
  
• Familiar with embedded implementation and communication protocols.
  
• Hands-on experience with inertial sensors and actuator control.
  

Nice to Have (Preferred):

• Practical 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 systems.
