About the role

Lumotive is pioneering the era of programmable optics-where light is controlled as intelligently and flexibly as software.
This breakthrough lays the foundation for a massive shift in multiple technologies-from 3D sensing and imaging to optical networking, free space optical communication, and beyond.
Like the shift from analog to digital in electronics, programmable optics will reshape industries from robotics, self-driving cars, AI, defense, and healthcare.

Own firmware architecture for multi-core embedded subsystems
Partition designs and justify tradeoffs across HW/FW/SW
collaborate with ASIC/SoC, digital design, verification, board, and systems teams.
Implement low-power firmware strategies (clock/power domains, sleep states, retention, wake sources) and validate current/latency targets.
Develop and optimize drivers and middleware for common interconnects (USB, JTAG, I²C, SPI, GPIO, UART, DMA)
Build production firmware for both prototyping platforms and formal product environments
manage transitions from lab to manufacturing.
Create host-side drivers/tools for Windows and Linux as needed (kernel/user-space interfaces, diagnostics, provisioning utilities).
Define and implement TDD workflows: unit tests, HIL/integration tests, test frameworks, and CI pipelines
Support board bring-up and validation

Bachelor's degree in Computer Science, Computer Engineering, or equivalent.
8+ years as a firmware/HW/SoC architect or senior embedded firmware engineer.
Proven experience with multiple embedded processor subsystems and integration into ASIC/SoC.
Proficiency with lab/debug tools: oscilloscopes, logic analyzers, JTAG/SWD, and network/protocol analyzers.
Solid grasp of computer architecture and OS principles (memory, concurrency, scheduling, interrupts, caches).
RTOS selection and bring-up (e.g., FreeRTOS, Zephyr, ThreadX) including BSPs, bootloaders, and startup code.
Firmware-controlled low-power design and measurement.
Multiple firmware boot modes, including secure boot, signing, key management, and recovery.
Driver development and HW module interfacing (USB, JTAG, I²C, SPI, UART, DMA).
Firmware and driver development for Windows and Linux environments.
Schematic/layout literacy for effective HW/FW co-debug.
TDD experience and ability to implement robust unit/integration test frameworks
CI with Git-based workflows.
Comfortable managing ambiguity and making sound tradeoffs with limited information

Comfortable managing ambiguity and making sound tradeoffs with limited information; strong written/spoken communication.
Experience defining HW datapath engines tightly coupled with firmware control loops.
Automotive/functional safety (e.g., ISO 26262) or similar safety-critical domain experience.
Secure manufacturing/provisioning, OTA/update strategies, and rollback.
Performance/power profiling and optimization on constrained systems.
Compliance practices (MISRA-C/CERT C), static analysis, and coverage tools.
