Role Summary
Play a key role in supporting the development, testing, and debugging of embedded software that brings electronic systems to life. This position involves hands-on interaction with hardware, writing and modifying low-level code, and assisting with the integration of firmware into physical devices. We seek a technician to help bring our custom camera hardware to life. The NanoCam X-Series hardware is just a shell until the firmware makes it functional — and that's where you come in.

Typical Responsibilities:
Firmware Development: Writing and modifying C/C++ code for the ARM processor to control the CMOS sensor, handle data, implement communication protocols.
Hardware Bring-Up: Working closely with the electronics technician to test and debug initial hardware functionality by writing small test programs.
Driver Development: Writing low-level drivers for peripherals and interfaces.
Debugging: Using debuggers to find and fix software bugs.
Version Control: Managing code using systems like Git.

Must-have Skills

Proficiency in C/C++ Programming:
Skilled in writing, reading, and modifying embedded C/C++ code for microcontrollers and low-level systems.

Understanding of Microcontrollers and Embedded Systems:
Familiar with ARM Cortex-M architectures and common development environments.

Hardware Interface Knowledge:
Basic working knowledge of hardware interfaces and protocols such as I2C, SPI, UART, GPIO, and CAN.

Debugging and Diagnostics:
Capable of using JTAG/SWD tools, logic analyzers, multimeters, and oscilloscopes to debug firmware–hardware interactions.

Ability to Read Schematics & Datasheets:
Understands electronic schematics, component datasheets, and block diagrams to support firmware-hardware integration.

Version Control:
Comfortable working with small components and precise firmware configurations that impact physical behavior.
Adheres to electrostatic discharge (ESD) protocols and basic lab safety procedures when handling sensitive hardware.
Strong written and verbal communication skills for documenting firmware behavior, writing comments, and working with cross-functional teams.

Adaptability & Team Collaboration:
Willingness to learn new tools, processors, or RTOS platforms. Works well independently or in support of a hardware/firmware team.

Digital Tool Proficiency:
Familiarity with embedded development tools, IDEs, digital documentation platforms and ticketing systems.

Contribution to Products:
Develops and maintains the firmware that drives product functionality, including communication, sensor control, and startup routines.
Supports hardware bring-up by writing test routines and helping identify physical or logical issues.
Maintains a well-organized firmware development and testing environment, contributing to clean and repeatable build cycles.
Develops the core functionality, that enables communication, and makes the NanoCam X-Series devices actually work.
Develop the core functionality of the device (X100, X200, XPro and XUltra models) that Enable communication between hardware components and complementary web/mobile apps.
Work directly with our hardware team to prototype, test, and ship working systems

What you will do:
Firmware Development: Write and modify C/C++ code/logics for ARM-based microcontrollers to control CMOS sensors and manage data flow.
Hardware Bring-Up: Collaborate with electronics technicians to test new hardware by developing low-level test programs.
Driver Development: Implement and debug low-level drivers for peripherals and interfaces.
Debugging: Use tools like JTAG/SWD probes to track down bugs, test edge cases, and ensure stability in hardware–software integration.
Version Control: Keep code clean, track changes, and collaborate using Git.

Continuous Improvement:
Learns and applies at least one new tool, protocol, or platform per quarter (e.g., JTAG debugging, RTOS basics, Git workflows).
Regularly incorporates peer feedback and shows visible improvement in code quality and troubleshooting efficiency.
Maintains a personal development log or project journal to track learning progress and challenges.

Documentation & Reporting:
Keeps firmware changelogs, test results, and hardware integration notes updated and accessible.
