🚀 Opportunity: Principal Engineers for Stealth Robotics Venture (YC S26)

An ambitious, stealth-mode robotics startup—currently part of the Y Combinator S26 cohort—is seeking world-class Principal Engineers to join their founding team in Palo Alto, California.

"We aren't just building a product; we are architecting the future of autonomous physical interaction. We need pioneers who can bridge the gap between theoretical AI and tangible, real-world robotic deployment."

🛠 The Mission & Technical Vision

The company is focused on developing the next generation of robotic systems. This involves a complex interplay between high-level intelligence and low-level precision.

The System Architecture

The following diagram illustrates the conceptual flow of the technology stack the new hires will influence:

The Mathematical Foundation

Engineers will be dealing with complex dynamics, often involving equations such as the general form of robot dynamics: $\tau = M(q)\ddot{q} + C(q, \dot{q})\dot{q} + g(q)$ Where $\tau$ represents the joint torques, $M$ is the inertia matrix, and $g(q)$ is the gravity vector.

📋 Role Overview

We are looking for individuals who can operate at the intersection of Hardware, Software, and AI.

Key Responsibilities

• Lead the design and implementation of robust robotic frameworks.
• Optimize real-time performance using C++ and Python.
• Integrate cutting-edge LLMs/VLMs into physical control loops.
• Mentor junior engineers as the team scales rapidly.

🎯 Candidate Profile

We are looking for "10x" engineers who are tired of maintaining legacy corporate codebases and want to build something from scratch.

Required Expertise:

• Deep Robotics Knowledge: Proficiency in ROS2, MuJoCo, or PyBullet.
• AI/ML Mastery: Experience with Reinforcement Learning (RL) or Transformer-based architectures.
• Hardware Fluency: Ability to work closely with electrical and mechanical engineers to iterate on prototypes.
• Proven Track Record: A history of shipping complex physical products.

Example Technical Challenge

You should be comfortable writing high-performance code similar to this snippet for motor control:

// Simplified PID Control Loop for Joint Actuation
double computeControlSignal(double setpoint, double measured_value) {
    double error = setpoint - measured_value;
    integral += error * dt;
    double derivative = (error - prev_error) / dt;
    return (Kp * error) + (Ki * integral) + (Kd * derivative);
}

🚀 How to Apply

If you are ready to leave the comfort of a Big Tech role for a high-stakes, high-reward venture, follow these steps:

• Update your CV/Portfolio to highlight physical systems you've built.
• Prepare a brief summary of your most challenging technical "win."
• Reach out via the official application channel.

Note: This is a strictly on-site role in Palo Alto to facilitate the rapid hardware iteration cycles required for stealth-stage development.
