· Shipped at least one camera, imaging, or real-time video pipeline product (sensor * pipeline * output).

· Comfortable with MIPI CSI-2, I2C, SPI, UART, USB, Ethernet, and reading electrical schematics.

· Board bring-up with JTAG, oscilloscope, logic analyzer. You have found the bug that was actually hardware.

· Can set architecture and explain it clearly to EE, FPGA, and a VP.

· Fluent with modern AI coding assistants (Cursor, Claude, Copilot-class tools). You already use them to move faster on real embedded work, and you can teach that practice to others.

· Demonstrated experience developing software for embedded systems.

· Experience working with microcontrollers, processors, hardware interfaces, and embedded operating systems or real-time operating systems.

· Strong understanding of software development lifecycle, debugging, testing, version control, and code review practices.

· Demonstrated ability to troubleshoot complex software and system-level issues.

· Experience providing technical leadership, mentoring, or management of other engineers.

Preferred:

· CMOS / low-light / NIR / IR imaging, or electro-optical products.

· FPGA * processor integration, Qualcomm or similar mobile/embedded SoC, RTOS (FreeRTOS, Zephyr).

· Bootloaders, secure boot, firmware update, power/thermal on a sealed camera.

· Python (or similar) for test harnesses, HIL, and factory bring-up.

· You hunt, fish, boat, or already use night vision.

· Time in the Goleta IR / camera cluster (FLIR/Teledyne, Moog, Umbra, or similar), marine electronics, drone/FPV firmware, or camera-module houses.

· Experience developing software for safety, quality or reliability-critical products.

· Previous formal people-management experience.

· Experience working in a fast-paced product development environment.

· Must be able to lift up to 25 pounds at times.

· Travel up to 25%. We have locations around the country, including Beverly, MA, Santa Barbara, CA and Whitefish, MT, so you will need to have the ability and willingness to travel, including internationally, * Bachelor's (Required), * embedded software product: 10 years (Required)

 * C++: 5 years (Required)
 * Technical Leadership: 5 years (Required)
 * people management: 3 years (Required)

Ability to Commute:

 * Goleta, CA 93117 (Required)

## Description

SIONYX is seeking a highly experienced and hands-on Embedded Software Engineer V to join our engineering team. This role will be responsible for designing, developing, integrating, testing, debugging, and maintaining embedded software for SIONYX's advanced imaging products., · Lead the development of complex embedded software solutions and serve as a technical resource for the engineering team.

· Own architecture for the embedded Linux / ARM video pipeline that takes XQE sensor data to a usable color night-vision image.

· Lead sensor bring-up, FPGA/MIPI CSI-2 integration, and the interfaces between image sensor, SoC, and the rest of the camera.

· Design, write, and debug C/C++ for microcontrollers, ARM SoCs, and embedded Linux, using AI coding assistants (Cursor, Claude, and peers) as a normal part of the workflow. Drivers, BSPs, and the application layer when the path from photon to pixel is on you.

· Sit with EE, FPGA, optics, and image-processing on board bring-up. Read the schematic. Use the scope. Close the loop on hardware/software together.

· Set the technical bar: design reviews, code reviews, performance/memory/power/real-time tradeoffs.

· Independently investigate and resolve complex technical issues involving software, firmware, hardware interfaces, and system performance.

· Mentor and develop less-experienced engineers through technical guidance, code reviews, knowledge sharing, and coaching.

· Take products from prototype through production and into the field. When a Nightwave dies on a helm or an Aurora misbehaves in the woods, you help find why.

· Evaluate new SoCs, sensors, and pipeline approaches. Recommend the next move.

· Lead technical projects or significant components of larger projects, coordinating priorities and deliverables with engineering and cross-functional partners.

· Work effectively with hardware, systems, product, manufacturing, and other teams to deliver reliable, high-quality products.

· Manage assigned engineers, including regular one-on-ones, goal setting, feedback, performance management, career development, and workload prioritization.

· Promote disciplined development, testing, documentation, and continuous improvement practices to ensure robust embedded software.

· Identify opportunities to improve development processes, tools, architecture, and team effectiveness.
