Digantara is a leading Space Surveillance and Intelligence  company focused on ensuring orbital safety and sustainability. With expertise in space-based detection, tracking, identification, and monitoring, Digantara provides comprehensive domain awareness across regimes, allowing end users to have actionable intelligence on a single platform. At the core of its infrastructure lies a sophisticated integration of hardware and software capabilities aligned with the key principles of situational awareness: perception (data collection), comprehension (data processing), and prediction (analytics). This holistic approach empowers Digantara to monitor all Resident Space Objects (RSOs) in orbit, fostering comprehensive domain awareness.

Digantara is seeking a highly skilled Senior Satellite Attitude and Orbit Control System (AOCS) engineer to be part of our dynamic team to conceptualize, architect the AOCS subsystem for cubesat/microsatellite. The engineer will be responsible for leading a team of multi-disciplinary engineers to design, develop and realize state of art AOCS subsystem.

Ideal Candidate

• Someone with strong expertise in leading the design, development of AOCS for Cubesat/Microsat operating in low earth orbit with strong focus on performance and reliability.

Responsibilities

• Architect, model, analyse & optimize the AOCS system for Cubesat/Microsat in low earth orbit to meet the satellite requirements.

• Collaborate with electrical/mechanical subsystem, payload engineers and derive the AOCS subsystem requirements.

• Lead the team of algorithms, embedded hardware and software engineers to design, develop AOCS with target performance, stability and agility requirements.

• Develop and implement attitude determination and estimation algorithms and carry out simulations to verify the AOCS performance and stability.

• Generate sensor, actuator and control system requirements and derive the high-level hardware, software requirements. 

• Select hardware components i.e., sensors, actuators and control electronics and develop specifications and ICDs for these components. 

• Develop unit level and integrated level test requirements for AOCS and generate the design, test reports during the development life cycle.

Qualifications

• 6 to 10 years of demonstrated experience in design, development of AOCS subsystem for LEO satellites.

• Strong understanding of control theory, spacecraft dynamics and embedded systems.

• Proficiency in MATLAB, Simulink or Python to model and analyse AOCS system.

• Deep understanding of the sensors i.e., sun sensor, star tracker, GPS receiver, magnetometers and actuators i.e., Magnetic torquers and reaction wheels and their interaction.

• Experience with Hardware In Loop(HIL) simulations, Software In Loop(SIL) simulation tests for the AOCS.

• Strong expertise in understanding and implementation of EMI/EMC control.

• Knowledge of orbit determination, estimation and propagation methods.

Preferred Skills 

• Technical leadership to drive the inhouse design and development of magnetic torquers, reaction wheels, star trackers.

• Experience with on-orbit AOCS operations for cubesat/microsat in LEO.

• Knowledge of embedded systems and flight software development, STK/Freeflyer/ GMAT or equivalent mission simulation tool.

• Understanding of satellite subsystems and systems-first development approach.

• Knowledge in data communication protocols such as I2C, UART, SPI, LVDS, RS422/485 etc.

• Familiarity with electrical ground support equipment to test the performance of AOCS at satellite level. 

General Requirements 

• Ability to work in a mission-focused, operational environment. 

• Ability to think critically and make independent decisions. 

• Interpersonal skills to enable working in a diverse and dynamic team. 

• Maintain a regular and predictable work schedule.
