First, the good news: The world now has over 1.7 terawatts of cumulative solar capacity and solar PV is the lowest-cost source of energy generation worldwide.

The challenge: The world must build 3 terawatts of new solar capacity every year for the next 25 years.

Planted is creating new technology to overhaul how the industry develops and builds solar power resources. And we need help. We're expanding our team of ambitious, curious, and hands-on engineers and operators. Come own large parts of product, company, or business development and help power the world with 100% clean energy.

About The Role

As a key member of the Robot Software team, you will design and develop high-performance Qt-based GUIs for Human-Machine Interaction (HMI) with Planted Solar’s Semi-Autonomous machines. This role involves hands-on testing in both controlled and field environments to optimize user experience and ensure system reliability. You will build and maintain CI pipelines for desktop apps and HIL testing that provide fast feedback, reproducible builds, and traceable artifacts. You are a software generalist who moves comfortably between UI polish, performance profiling, test automation, and backend integrations to keep the team unblocked. This role offers plenty of room for growth, whether you're interested in data infrastructure, backend services, or diving deeper into core robot telemetry and logic.

This position offers the opportunity to collaborate closely with a highly skilled cross-functional engineering team, taking ownership of projects from ideation to implementation to enhance the usability and reliability of our robotic systems in challenging real-world environments.

The salary range for this full-time position is $120,000 - $155,000 plus stock options and benefits. Pay within the range is based on candidate experience, job-specific skills, education, and work location. The target experience for the position is 3 - 7+ years

RESPONSIBILITIES

Build and own a user-facing industrial robot GUI/HMI with Qt (C++/Qt Widgets/Qt Quick/QML) or Python (PySide/PyQt): architecture, implementation, testing, and release
Integrate with robot backends (ROS 2 nodes/services/actions/parameters) for telemetry, command/control, and workflows.
Conduct hands-on testing of GUIs and input devices in field environments and our testing yard to understand user needs and ensure reliability
Design UI-adjacent APIs and collaborate with backend teams for telemetry, command/control, and workflows
Create and run CI for desktop apps and HIL tests; manage artifacts, versioning, and reproducible builds
Profile and optimize UI performance; implement robust state machines, threading, and signal/slot patterns
Ensure security and reliability in the UI: role-based views, safe command workflows, and watchdog indicators
Pitch in where needed like a startup generalist: from quick UX prototypes to low-level performance work, and occasional backend/integration tasks to unblock the team

QUALIFICATIONS

Bachelor’s or Master’s degree in CS, EE, ME, or equivalent
3 - 7 years of professional experience in software development
Excellent communication, collaboration, and teamwork abilities
Proficiency in designing and developing Qt-based GUIs (C++ or PySide6/PyQt)
Experience with Python 3.10+ or modern C++ (C++17+) for application development and automation
Strong understanding of concurrent programming principles
Well-versed with developing software for Linux environments
Adept at writing Bash scripts for automation and system management
Knowledgeable of SQL and database fundamentals
Familiarity working in Docker containers and container deployment
Excellent problem-solving and analytical skills
Curious demeanor and excited to learn new technologies when necessary
Prioritizes delivering user value while making pragmatic technical tradeoffs
Thrives in startup environment as a generalist: comfortable wearing multiple hats, context-switching, and owning work end-to-end under ambiguity
Based in the SF Bay Area (or willing to relocate) and available on-site 80%.

PREFERRED QUALIFICATIONS

Experience with pub/sub architectures (ROS 2, MQTT, etc)
Experience with embedded systems
Experience with UI testing frameworks and hardware-in-the-loop workflows
Experience building simple web applications for internal dashboards or tooling
