Job Requirements
At Quest Global, it’s not just what we do but how and why we do it that makes us different. With over 25 years as an engineering services provider, we believe in the power of doing things differently to make the impossible possible. Our people are driven by the desire to make the world a better place—to make a positive difference that contributes to a brighter future. We bring together technologies and industries, alongside the contributions of diverse individuals who are empowered by an intentional workplace culture, to solve problems better and faster.
Key Responsibilities
- Develop accurate mathematical models of dynamic systems (mechanical, electrical, thermal, etc.) using first-principles physics or system identification techniques
- Perform designing, tuning, and implementing various controllers, especially PID controllers (Proportional-Integral-Derivative), as well as advanced techniques like model predictive control (MPC), robust control and nonlinear control
- Developing and running complex dynamic system simulations in Simulink using Control System Toolbox and System Identification Toolbox.
Code generation from Simulink models (e.g., Embedded Coder) for real-time systems in MATLAB/SimulinkWe are known for our extraordinary people who make the impossible possible every day. Questians are driven by hunger, humility, and aspiration. We believe that our company culture is the key to our ability to make a true difference in every industry we reach. Our teams regularly invest time and dedicated effort into internal culture work, ensuring that all voices are heard.We wholeheartedly believe in the diversity of thought that comes with fostering a culture rooted in respect, where everyone belongs, is valued, and feels inspired to share their ideas. We know embracing our unique differences makes us better, and that solving the worlds hardest engineering problems requires diverse ideas, perspectives, and backgrounds. We shine the brightest when we tap into the many dimensions that thrive across over 21,000 difference-makers in our workplace.
Work Experience
Technical & Theoretical Knowledge
- Deep understanding of classical control (e.g., Laplace transforms, transfer functions, stability analysis like Routh-Hurwitz and Nyquist criteria, root locus) and modern control (e.g., state-space representation, controllability, observability, LQR).
- Knowledge of filtering, sampling theory, digital control, and discrete-time systems
- Strong background in physics, mechanics, electrical circuits, and thermodynamics, depending on the application domain.
Software & Programming Skills
- Proficient in Python. C/C++ Essential for embedded systems, real-time operating systems (RTOS), and high-speed controller implementation
- Expertise in MATLAB/Simulink
- Knowledge in PLC Programming (Industrial Automation): Ladder Logic (LD), Structured Text (ST), Function Block Diagram (FBD), and Sequential Function Charts (SFC) for major platforms (e.g., Siemens, Rockwell/Allen-Bradley).
Hardware & Implementation Skills
- Robotics and motion control: Kinematics deals with the geometry of motion, dynamics and feed forward forces, trajectory generation.
- Sensors and Actuators: Knowledge of selecting, integrating, and calibrating various types of sensors (e.g., encoders, accelerometers, pressure transducers) and actuators (e.g., motors, valves, pumps).
- Data Acquisition (DAQ): Experience with DAQ hardware and interfacing it with computers or embedded systems.
- Embedded Systems: Understanding of microcontrollers (e.g., Arduino, ARM, FPGAs) and how to implement control algorithms on them, including real-time programming and low-level driver development.
- Industrial Networking & Protocols: Familiarity with communication standards like Ethernet/IP, PROFINET, Modbus, CAN bus, and general industrial cybersecurity principles.
Analytical & Soft Skills
- Troubleshooting & Diagnostics: Ability to identify root causes in complex physical and software systems, whether it's an unstable loop or a faulty sensor.

- Problem-Solving: Strong analytical mindset to translate real-world requirements into mathematical control problems and derive practical solutions.
- Documentation and Communication: Ability to clearly document control system designs, tuning procedures, and test results, and effectively communicate technical concepts to both technical and non-technical teams.
Safety and Standards
- Functional Safety: Deep understanding of industrial safety standards (IEC 61508/62061, ISO 13849) and ability to design systems to achieve required Performance Levels (PL) or Safety Integrity Levels (SIL).
- Safety PLC Programming: Designing and implementing safety-rated logic (e.g., using GuardLogix or Siemens F-PLCs) for safety devices (light curtains, safety scanners, emergency stops).
- Risk Assessment: Conducting risk assessments for robotic cells to define safe zones, collaborative limits, and protective measures (especially critical for collaborative robot installations).
Academic Qualification
- Graduate/Post-Graduate in Electronics & Communication/ Controls & Instrumentation/ Mechatronics/ Electrical & Electronics Engineering with 6-8 years of experience in a reputed organization.
