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.

Your ideas and code will directly impact thousands of users across 40+ countries already using our product.

What You’ll Do:

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

Define requirements and architect AI-powered wearable applications

Build across Android XR (Kotlin/Java), iOS (Swift), and Android (Kotlin)

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

Today’s interfaces were built for the pre-AI era. That’s about to change—for the 4.7 billion people using smartphones today.

The race is on to define the next interface. At AirCaps, we're betting everything on voice-first software and hardware.

If we're right, we'll own the gateway to the next computing platform.
