A role at the core of a rapidly growing, deeply technical team
The opportunity to define how AI interacts with the physical world
Apply now for immediate consideration!
Founding Engineer, ML Systems (Humanoids)
Network engineer job in San Francisco, CA
We are building a general AI for humanoid robots that learns in the real world with minimal human supervision. Our approach is based on world-model-based reinforcement learning trained on large-scale data that is practical to collect. This makes it possible to learn reliable behaviors and improve beyond human performance limits. As a founding engineer, you will design and build core systems while helping shape the technical direction from the ground up.
Responsibilities
Build data pipelines that scale to 100k+ hours of multimodal robot data
Scale pre- and post-training runs on 1000s of GPUs
Improve inference efficiency on low-power embedded systems
Lead core architectural decisions, help define the long-term technical roadmap, and set engineering standards from the beginning
Qualifications
Strong practical experience building software infrastructure
Experience implementing and debugging distributed systems
Extensive experience in Python and at least one deep learning library such as PyTorch or JAX
Ideally experienced in implementing scalable training pipelines for world-model-based RL
Experience with systems programming languages (e.g. Rust, C++) is a plus
We're a small, focused team where your contributions would have a major impact. As a founding team member, you'd also have significant ownership in what we're building together - we believe in giving our early engineers meaningful equity that reflects their foundational role.
AI Engineer - Voice
Network engineer job in Fremont, CA
Head of Voice AI
San Francisco, CA (in-office, relocation supported)
We're partnering with a YC-backed startup that's building an AI-powered platform to reinvent one of the world's largest industries. Voice is at the core of how their customers do business, and they're hiring a AI Engineer - Voice to own the design, deployment, and scaling of voice systems that will power thousands of conversations every day.
This is a hands-on leadership role where you'll prototype rapidly with low-code tools (VAPI, Retell) and then scale into custom voice infrastructure (LiveKit, Pipecat, WebRTC) as the company grows. You'll build systems that handle everything from outbound prospecting to multi-turn applications, underwriting support, and 24/7 customer service - all while keeping latency below 700ms and delivering real business impact.
What You'll Do:
Deploy production voice agents in weeks, not months, to drive immediate growth
Architect scalable infrastructure capable of handling 10,000+ concurrent calls
Build outbound agents that qualify leads, book meetings, and close pipeline gaps
Develop intelligent, multi-turn conversation workflows for long-form applications
Launch 24/7 voice agents for servicing, claims, payments, and renewals
Create internal tools and analytics to measure and optimize conversation quality
About You:
5+ years of software engineering experience, with 3+ focused on voice/audio systems
Hands-on experience deploying production voice AI systems at scale (50K+ minutes/month)
Strong background in telephony and real-time audio (SIP, RTP, WebRTC, VAD, AEC, noise suppression)
Proficiency in Python and TypeScript/Node.js for real-time systems
Deep knowledge of modern STT/TTS and conversational AI providers (OpenAI, Anthropic, Deepgram, ElevenLabs, etc.)
Track record of shipping features fast and measuring success by business outcomes
Based in San Francisco (or willing to relocate) and excited by an in-office, high-intensity startup culture
Why Join:
This is an early hire at a YC startup where voice is the biggest lever for scale. You'll work shoulder-to-shoulder with the founders, ship daily, and directly impact revenue, efficiency, and customer experience. If you've built voice AI before and want to push the limits of what's possible in real-world production environments, this is the role to do it.
