Embedded Systems Engineer

Bellatrix Aerospace; Bengaluru; On-site; INR 1,200,000 - 1,800,000; Full time

Job summary

Bellatrix Aerospace in Bengaluru seeks an Embedded Hardware/Software Design Engineer who will own the full embedded lifecycle—from requirements and architecture to hardware design, firmware development, integration, testing and final qualification. The role combines hardware and software responsibilities across teams to deliver robust embedded systems.

The candidate should possess strong hands-on skills with microcontrollers, peripherals, debugging, and testing, and be ready to drive subsystems

Qualifications

• Strong fundamentals in analog and digital electronics.
• Good understanding of embedded hardware architecture and board-level design.
• Hands-on experience with board bring-up and debugging.

Responsibilities

• Understand system-level requirements and translate them into hardware and software architectures.
• Design embedded electronic systems including microcontroller/processor-based architectures, power distribution, and interfaces.
• Develop and debug embedded firmware in C/C++ and for peripherals and communication protocols (UART, SPI, I2C, CAN/CAN-FD, RS-232/RS-422/RS-485).
• Develop device drivers, board-support software, and application-level embedded software.
• Work with bare-metal and RTOS-based systems; perform board bring-up and hardware validation.
• Participate in design reviews, root-cause analysis, and maintain engineering documentation.

Job description

We are looking for a dynamic and hands‑on Embedded Hardware/Software Design Engineer who can work across the complete embedded system development lifecycle. The ideal candidate should have a strong understanding of both electronics hardware and embedded software and should be comfortable taking a system from requirements and architecture through hardware design, firmware development, integration, testing, debugging, and final qualification. This role is suited for engineers who enjoy understanding the complete system, rather than working exclusively within either hardware or software.

About the Role

A short paragraph summarizing the key role responsibilities.

Responsibilities

• Understand system‑level requirements and translate them into hardware and software architectures.
• Design embedded electronic systems including:
• Microcontroller / processor‑based architectures
• Power supply and power distribution circuits
• Analog and digital interfaces
• Sensors and actuator interfaces
• Communication interfaces
• Memory and peripheral interfaces
• Perform component selection, schematic design, design reviews, and PCB design coordination.
• Develop and debug embedded firmware in C/C++.
• Develop firmware for peripherals and communication protocols such as:
• UART
• SPI
• I2C
• CAN / CAN‑FD
• RS‑232 / RS‑422 / RS‑485
• Ethernet and other interfaces as required
• Develop device drivers, board‑support software, and application‑level embedded software.
• Work with bare‑metal and/or RTOS‑based embedded systems.
• Perform board bring‑up, hardware validation, firmware integration, and system‑level debugging.
• Debug hardware and software issues using oscilloscopes, logic analyzers, multimeters, debuggers, protocol analyzers, and other laboratory equipment.
• Develop test setups, test firmware, and validation procedures.
• Participate in design reviews, failure analysis, root‑cause analysis, and design improvement activities.
• Prepare and maintain engineering documentation including architecture documents, interface definitions, schematics, test procedures, design notes, and test reports.
• Work closely with mechanical, electronics, software, RF, systems, testing, manufacturing, and other engineering teams.
• Take ownership of assigned subsystems and drive them from concept through implementation and validation.

Qualifications

• B.Tech / B.E. in Electronics & Communication Engineering (ECE) or a closely related electronics discipline

Required Skills

• Strong fundamentals in analog and digital electronics.
• Good understanding of microcontrollers, processors, memories, ADCs, DACs, sensors, and common peripheral devices.
• Good understanding of embedded hardware architecture and board‑level design.
• Strong programming skills in Embedded C/C++.
• Understanding of microcontroller peripherals, interrupts, timers, DMA, watchdogs, boot processes, and memory architectures.
• Experience with common embedded communication protocols.
• Ability to read and understand schematics, datasheets, timing diagrams, and hardware specifications.
• Hands‑on experience with board bring‑up and debugging.
• Ability to debug problems spanning both hardware and firmware.
• Good analytical and system‑level problem‑solving abilities.

Preferred Skills

Candidates with experience in one or more of the following will have an advantage:

• ARM Cortex-M based microcontrollers
• STM32, Microchip SAM, NXP, TI, Renesas, or similar platforms
• FreeRTOS or other RTOS platforms
• CAN, RS‑422/485, Ethernet, USB or other industrial communication interfaces
• Bootloaders and firmware upgrade architectures
• ADC/DAC and sensor interfacing
• Power electronics and DC‑DC converter design
• EMI/EMC‑aware PCB and system design
• Hardware‑in‑the‑loop or automated testing
• Python scripting for testing and automation
• Git and modern software development workflows
• FPGA interfaces or basic FPGA knowledge
• High‑reliability, aerospace, defence, automotive, robotics, industrial, or other complex embedded systems
