Job Title
Founding ML Engineer
Salary
$180K 1% Equity
Company Description
BehaviorAI is a top-tier VC-backed startup and Cornell SciFi Lab spinout building AI models to understand human behavior through wearable sensors.
Job Description
As a Founding ML Engineer at BehaviorAI, you will architect and deploy state-of-the-art multimodal models for real-world time-series sensor data. You’ll design novel architectures from scratch—moving beyond simple fine-tuning—to power next-generation wearable intelligence. This hands-on role involves shipping direct-to-user solutions in a high-energy, proactive startup environment.

Brooklyn, USA
Why this role is remarkable
Who are Jack & Jill?
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.
And I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate.
How does this work?
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
She will pick the best candidates from Jack's network.

Why this role is remarkable
- Work directly with founders Cheng Zhang (NSF CAREER Award winner) and Mehrab Bin Morshed (ex-Samsung Research) at the intersection of academia and industry.
- Influence the core product by designing novel ML architectures from scratch rather than just fine-tuning existing models for specific hardware.
- Join a top-tier VC-backed founding team with significant equity and the ability to shape a Cornell SciFi Lab spinout from day one.
- Architect and deploy SOTA multimodal models (CV, NLP) specifically optimized for real-world time-series data from wearable sensors.
- Develop and implement real-time inference and on-device machine learning capabilities to ensure low-latency performance in field settings.
- Drive the technical roadmap for foundation models that integrate multi-modal sensing to deeply understand human behavior and intent.
- Proven experience processing real-world sensor or time-series data (e.g., image, IMU) with a focus on real-time inference and on-device ML.
- Strong background in Foundation Models and multimodal sensing, with the technical ability to build and iterate on complex architectures.
- High-energy, proactive mindset suited for an early-stage startup, with a willingness to own technical problems from research to final production.
