Sr. Robotics Software Engineer

The Role

We're looking for a Senior Robotics Software Engineer who is comfortable working with real hardware and wants to solve the perception, control, and autonomy challenges required to make our machines functional, reliable, and economical.

As a Senior Robotics Software Engineer, you will contribute across our stack: improving detection on the bed with our depth camera systems, using our soft grippers to pick mushrooms while minimizing damage, and programming our harvest intelligence to maximize the output of our customers’ crops.

Growing and harvesting Mushrooms is a complex biological process, and our systems generate mountains of data that we use to understand and improve how our machines perform. You'll work alongside and guide the teams responsible for managing that data, and use it to measure our performance and build the interfaces our customers rely on. Working with growers in Canada, Europe,and Australia and occasionally visiting our deployments at their sites, you will come to have an in-depth understanding of mushroom growing, if not a genuine appreciation for it.

If any of the following sounds like you and if this is where you aspire to learn and to take your career, you may be a great fit for robotics engineering at 4AG.

You’ve worked with hardware before, and you understand what it takes to interface with sensors and motor drives and to coordinate multiple autonomous systems. The thought of debugging multiple 50 kg machines inside an active mushroom-growing room sounds like a good time. The thought of building the remote diagnostics, tooling,and testing that keep those machines running without engineers on site sounds even better.

You understand the work required to take a prototype and put it into production.

You’ve implemented perception and/or control features. You can stitch depth images together, use them to localize, and generate the trajectories to act on them. You’ve targeted and tracked something with a vision system and then grasped it with a manipulator, in simulation or in real life. You understand the role that intrinsic and extrinsic calibration plays in sensor fusion.

You’ve worked with modern robotics tooling: simulation, visualization, logging,and frameworks such as ROS
2. You can remotely diagnose and update a system on the other side of the planet, and you know what it takes to manage a fleet of robots across multiple sites. You understand the power of modern A.I. tools, but you’re still in the driver’s seat. Mostof all, you’re genuinely curious about robotics and technology and how they apply to agriculture and the natural world.

You’re willing to chart your own course while building a product that has never been fielded before, and to dig into the finer details and the data behind mushroom harvesting.

This role requires broad expertise, grit, and a willingness to learn new things in mushroom agriculture, robotics,and business. Along with robotics engineering, our team members are charged with understanding our customers, our product, and operating our machines in the test lab and in the field.
