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

Firmware Architecture & Development

• Design, develop, and maintain embedded firmware for ARM Cortex‑M and TI MCU platforms.
• Develop and optimize peripheral drivers, middleware, communication stacks, and board support packages (BSP).
• Implement modules involving ADC/DAC, PWM, DMA, timers, watchdogs, interrupts, and low‑power modes.
• Architect RTOS‑based systems using FreeRTOS or similar operating systems.

Hardware–Software Integration

• Collaborate with hardware teams for board bring-up, schematic validation, and design reviews.
• Debug hardware/firmware integration issues using oscilloscopes, logic analyzers, and JTAG/SWD.
• Validate and tune interfaces such as:
• SPI, I²C, UART, CAN, LIN
• Modbus/RS485, Ethernet, Profinet
• USB or proprietary protocols

System Optimization & Reliability

• Optimize real‑time performance, memory usage, and power consumption.
• Implement robust error‑handling, diagnostics, and state‑machine‑driven architectures.
• Perform code reviews, static analysis, unit testing, and regression testing.

Documentation & Quality

• Prepare architectural documents, design specifications, interface definitions, and API documentation.
• Ensure firmware quality through coding standards (MISRA‑C or equivalent).
• Support validation engineers and ATE teams with firmware‑level hooks and testability features.

Cross‑Functional Collaboration

• Work closely with system, hardware, ATE, and validation teams.
• Provide mentorship and technical leadership to junior firmware engineers.
• Participate in system‑level architecture decisions including communication frameworks, bootloaders, and security features.

We 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.
