About Greenlight Robotics

Significant travel to customer sitesAbout Greenlight Robotics

Greenlight Robotics is building public transit technology that makes communities more efficient, accessible, and vibrant, and we’re building a team of people who care deeply about how cities are run.We’re hiring our first core team of engineers to deliver the initial production version of our system to early transit customers. You will be hands‑on building cutting‑edge technology that will strengthen the public systems moving billions of people every day.

About The Role

We are looking for a

Robotics Perception Engineer

to build the perception stack of our product. Reporting directly to our Co-founder & CTO, you will write, review, and deploy software that powers the data collection, object detection, sensor fusion, localization, and systematic model improvement underlying our product.

This role offers an extremely high learning velocity, and you will work directly alongside the founders and our Lead Robotics software Engineer to own major components of a complex, field‑deployed system.

What We Are Looking For

• Vehicle AI & Perception:
  You have 4+ years experience building and training vehicle perception models with sensor fused 2D and 3D lidar data.
• Complex Architecture Engineering:
  Demonstrated ability to create, maintain, and optimize complex robotic software within an integrated HW/SW product
• AI-Accelerated Coder:
  Ability to write and evaluate high-quality code using LLMs as an accelerating tool to increase output without building up technical debt.

What You Will Do

• Build & Ship Core AI Models:
  Evaluate, implement, and continuously improve AI/ML/RL models for perception, sensor fusion, and object detection algorithms.
• Optimize Software Architecture:
  Develop and maintain major components of our software stack, driving code quality and execution to enable core features for our first transit customers.
• Drive Product Iteration:
  Build out data collection pipelines to enable rapid, systematic iteration of our physical‑world robotics algorithms.
• Shape the Technical Roadmap:
  Independently identify performance bottlenecks across our software components and help prioritize our next technical features and improvements.

Bonus Points

• Master’s or PhD in Robotics, Computer Science, or equivalent focus.
• 6+ years of previous experience developing perception stacks
• Previous experience in semi-automated or automated vehicle platforms.
• Hands-on experience working directly on the hardware side of a complex robotics implementation.

What We Offer

• Competitive salary and ground‑floor equity package.
• Comprehensive benefits including medical, dental, vision, disability, and commuter.
• Generous "flex days" for working from home alongside unlimited PTO.
