Product Engineer
Job Description
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.
