About this role
We’re hiring the first product engineer for our AI smart glasses: AirCaps.
You’ll own core apps and functionality end-to-end: building, testing, and shipping AI experiences for a consumer wearable.

Brainstorm, validate, and define new features using real customer data and interviews alongside the founders

Design and optimize agentic pipelines using streaming multimodal models (audio, vision, text)
Push performance across latency, reliability, accuracy, power consumption—and even thermals when it matters
Ship fast: test, QA, release → fix bugs as soon as things break → iterate on high-signal user feedback at lightning speed
You Might Be a Fit If You:
Thrive in 0→1 environments, from ideation through production and iteration
Obsess over craft. The details matter to you across the whole stack, from data models to pixel-level UI details
Ship work you're actually proud of and have a track record of doing so.
Want to build products that impact thousands of real consumers.
Are Claude Code native (or AI of your choice)
Have grit: you're willing to chase hard optimization problems where every 100ms matters
Are fascinated by how humans will interface with technology (bonus if you’ve imagined building a real-life JARVIS)
Why Join AirCaps:
Be early at a company defining the next computing platform
See your work in the hands of users across the U.S., Europe, Korea, India, Japan, and 30+ other countries
Work directly with the founders and shape product direction
