Software Platform Engineer

About the Company

The datacenter buildout is the largest industrial project in human history. Gradient builds the autonomous robots that make it possible.

Partnered with the world's largest AI infrastructure companies and backed by the industry's best investors, we move fast and build full-stack systems that matter.

About the role

We're looking for a Software Engineer to help move data from AI models to actuators. You'll work close to the hardware, from kernel and firmware up through the controls and perception layers, contributing to real-time pipelines that move hundreds of megabytes at single-digit millisecond latency. Vision inference, control loops, and actuation all live on the same clock, and you'll help keep them there. The goal: bring visibility and determinism into the end-to-end inference pipeline so the ML model is the only stochastic component. We iterate fast (multiple robot generations in months, not years), so the code you ship lands on real machines doing real precision work almost immediately.

Responsibilities

Ship performance-critical code to real robots daily

Learn the full data flow: camera frames in, perception and planning in the middle, control commands and actuator feedback out, and the systems that carry them

Contribute to the real-time control loop: help keep high-rate control running deterministically alongside vision inference

Build pieces of the perception data path: move high-bandwidth camera streams into the CV and ML models with minimal latency and zero silent drops

Push down latency and tighten the stack to make the system faster, more deterministic, and more reliable

Bring visibility into the pipeline: build tooling and instrumentation that make real-time behavior across controls and vision observable and debuggable

Minimum Qualifications

1+ years of software engineering experience building systems close to hardware (exceptional new grads with strong project or internship experience are welcome to apply)

Strong programming fundamentals in at least one of Rust, C++, or Python, with solid understanding of operating systems and multithreading

Experience building things: production systems, internal tools, student teams, or personal projects that worked

Debugged real timing, concurrency, or hardware issues, even in a project setting

Comfort with ambiguity and a strong learn-by-doing instinct

Able to work on-site in San Francisco 5 days/week (6 days/week if needed during crunch time), embedded in the team

Preferred Qualifications

Linux kernel or embedded systems experience

Exposure to build and test infrastructure: Bazel, Nix, HIL testing, or CI/CD

Experience with real-time control systems: motor control, high-rate control loops, or robot controllers

Computer vision pipeline experience: camera drivers, image transport, GPU inference, or sensor synchronization

Tracing and profiling experience: ftrace, flamegraphs, eBPF

Comfort using AI tools to multiply your own output
