Key Responsibilities
# Key Responsibilities
- •Design and implement embedded firmware (Daily)
- •Write and maintain C/C++ code for microcontrollers (ARM Cortex-M, RISCV) to meet timing and memory budgets (typical targets: <64 KB RAM, <512 KB flash). This ensures product features run reliably on target hardware.
- •Hardware bring-up and debugging (Daily/Weekly)
- •Use oscilloscopes, logic analyzers, and JTAG to diagnose boot, power, and peripheral issues. Resolve root causes so prototypes progress to stable alpha builds within 2–4 weeks.
- •Realtime and driver development (Weekly)
- •Implement device drivers and RTOS tasks (FreeRTOS, Zephyr) for sensors, communications (I2C, SPI, UART, CAN). Proper drivers reduce power draw by 10–30% and improve responsiveness.
- •System-level testing and validation (Weekly)
- •Define test cases, run hardware-in-the-loop and unit tests, and track failures. Deliver test coverage reports and reduce regression rate by measurable amounts.
- •Code reviews and CI/CD maintenance (Daily/Weekly)
- •Review peer code, enforce MISRA or project style, and maintain CI pipelines (unit tests, static analysis). This raises code quality and shortens release cycles.
- •Cross-functional collaboration (Weekly)
- •Work with electrical engineers and product managers to trade off BOM cost, performance, and schedule. Provide estimates and risk assessments for roadmap items.
- •Optimization and performance tuning (Strategic)
- •Profile CPU and memory hotspots, optimize algorithms, and lower latency by 20–50% when required for real-time features.
- •Mentoring and documentation (Strategic)
- •Write hardware integration guides, onboard new hires, and document test procedures to accelerate team delivery.
Actionable takeaway: Prioritize daily bring-up and debugging, schedule weekly integration tests, and set quarterly goals for performance gains and documentation.
Required Qualifications
# Required Qualifications
## Technical skills (must-have)
- •Proficient in C and C++ for embedded systems; write memory-safe code for devices with <256 KB RAM.
- •Experience with microcontrollers (ARM Cortex-M, STM32, NXP, TI) and peripheral buses (I2C, SPI, UART, CAN, 100 Mbps Ethernet).
- •Debugging tools: JTAG/SWD, oscilloscope, logic analyzer. Use these daily to fix boot and timing issues.
- •RTOS experience (FreeRTOS, Zephyr) and interrupt-driven design. Implement deterministic tasks and meet hard deadlines.
## Technical skills (nice-to-have)
- •Familiarity with Python for test automation and build scripting; experience with device firmware update (DFU).
- •Knowledge of bootloaders, secure boot, and basic cryptography for OTA updates.
## Soft skills
- •Clear communicator: produce concise bug reports and design notes; lead 30–60 minute weekly syncs.
- •Problem-solver: isolate causes under time pressure and prioritize fixes to meet sprint goals.
- •Team player: collaborate with EE and product teams to translate requirements into deliverable specs.
## Education / Certifications
- •Bachelor’s degree in Electrical Engineering, Computer Engineering, or CS (required). Equivalent hands-on experience (3+ years) accepted.
- •Certifications such as Embedded Systems Professional or MISRA training (nice-to-have) show formal process knowledge.
## Experience requirements
- •3–6 years building embedded firmware for products shipped to customers or deployed in field; experience with released hardware is preferred.
- •Demonstrated project contributions: completed at least one product cycle from prototype to production, including test plans and release notes.
Actionable takeaway: Hire for strong C/RTOS skills and practical hardware debugging; value shipped-product experience and clear communication.
