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.

What Success looks like

Technical Accuracy:

• Writes clean, efficient, and well-documented C/C++ firmware that functions as intended with minimal bugs.
• 90%+ of initial test cases pass without needing major rework.
• Demonstrates a solid understanding of microcontroller peripherals and low-level hardware interactions.

Reliability:

• Completes tasks and deliverables on or before assigned deadlines 90% of the time.
• Follows coding standards, testing protocols, and version control procedures with high consistency.
• Takes ownership of assigned modules or test scripts and maintains them without frequent supervision.

Team Collaboration:

• Participates actively in stand-ups, code reviews, and integration sessions with hardware and software teams.
• Communicates blockers or issues clearly within 24 hours of discovery.
• Provides at least one documented contribution per sprint cycle (e.g., bug fix, test function, driver module).

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.
• Achieves 100% traceability of test results to firmware versions during validation cycles.
• Writes or contributes to internal documentation/wiki entries at least once per month.

Experience:
