Job summary

5V Tech is seeking a Senior Embedded Software Engineer to advance edge AI and audio signal processing on embedded Linux SBCs. You will build real-time inference pipelines, optimize C/C++ software, and collaborate with hardware engineers to qualify new sensors.

The role emphasizes CI/CD ownership, security and networking for edge-to-cloud data flows, and close teamwork with a small, high-trust engineering group in the SF Bay Area.

Qualifications

• Experience in audio engineering or acoustic/DSP signal processing is essential.
• Strong Linux and C/C++ skills; assembly language experience is a plus.
• Able to collaborate with hardware design teams and manage CI/CD pipelines.
• Based in the San Francisco Bay Area; no visa sponsorship available.

Responsibilities

• Support and grow a lean edge engineering function, reducing key-person dependency on the existing team.
• Design, integrate, and qualify hardware components on embedded Linux SBC platforms, focusing on acoustic/audio sensing systems.
• Develop and maintain C/C++ software for real-time, on-device inference, including audio signal processing pipelines, with some assembly work.
• Own CI/CD pipelines and build/release processes for embedded deployments.
• Apply networking and security best practices across edge-to-cloud data pipelines.
• Work directly with hardware designers to prototype and qualify new sensor components.

Job description

Senior Embedded Software Engineer – Edge AI / Audio Signal Processing

Full-Time Permanent

Total Comp: Performance Bonus, Stock Options, Medical, Dental, Vision, 401(k), PTO

A well-established technology company builds mission-critical edge AI hardware products deployed in the field at scale. Their systems combine acoustic sensing with embedded Linux single-board computers, performing on-device inference and feeding real-time data to cloud backends for enterprise customers.

The edge engineering team is currently small, with deep technical knowledge concentrated in very few individuals. This hire will work directly alongside the team's senior embedded engineer to build redundancy and expand in-house capability, with potential for a second hire later this year.

Key Responsibilities:

• Support and grow a lean edge engineering function, reducing key-person dependency on the existing team
• Design, integrate, and qualify hardware components on embedded Linux SBC platforms, with a focus on acoustic/audio sensing systems
• Develop and maintain C/C++ software for real-time, on-device inference, including audio signal processing pipelines, with some assembly work
• Own CI/CD pipelines and build/release processes for embedded deployments
• Apply networking and security best practices across edge-to-cloud data pipelines
• Work directly with hardware designers to prototype and qualify new sensor components

Ideal Profile:

• Background in Physics, Electrical Engineering, or a related technical field strongly preferred
• Meaningful experience in audio engineering or acoustic/DSP signal processing is a core requirement, not a nice-to-have
• Broad systems thinker, comfortable working across hardware and software
• Strong Linux and C/C++ skills; assembly language experience a plus
• Solid grounding in CI/CD, networking, and security fundamentals
• Able to communicate effectively with hardware design teams
• Based in the San Francisco Bay Area; no visa sponsorship available

This is a rare opportunity to join a small, high-trust edge engineering team at an established company with a well-proven, sensor-driven product line, with real influence over how the team is built out.
