Embedded Software Engineer — mutual

We make digital content provably authentic at the hardware level.

AI-generated media is indistinguishable from reality. Software detection doesn’t work. At mutual, we’re building cryptographic signing directly into camera hardware—so content is authenticated the moment it’s captured.

Corporate introduction: Introducing mutual

The Role

We need someone to own the firmware stack—from Linux bring-up to TrustZone secure world code to camera pipeline integration.

You’ll work closely with our hardware engineer on the reference implementation, and eventually help scale this to production devices.

What You’ll Build

• Embedded Linux (Buildroot/Yocto) for vision SoCs
• OP-TEE trusted applications for real-time video signing
• Camera capture and encoding pipeline
• Secure boot chain implementation

Requirements

• Experience with embedded Linux development
• Comfortable reading datasheets and schematics
• Can work in Seoul (SNU campus) or hybrid

Nice to Have

• ARM TrustZone / OP-TEE experience
• Camera pipeline work (V4L2, ISP tuning)
• Experience with Rockchip or similar vision SoCs

What We Offer

• Competitive equity for early team member
• Interesting technical problem
• Small team, high ownership
