Staff Software Engineer

As a Staff Software Engineer on our Robotics Platform team, you will be a technical leader shaping the core of our autonomous systems. You will design and build the foundational software architecture that enables robust communication, high performance, and seamless integration across our fleet of unmanned ground vehicles.

This is a role for a systems thinker who thrives on complex technical challenges. You will collaborate closely with cross-functional engineering teams to establish best practices and create a cohesive, scalable runtime platform for our teleoperated and autonomous robots. Your work will directly influence the reliability and capability of technology that matters.

What You’ll Build

• The core software architecture for our robotics platform, ensuring robust communication and optimized performance across distributed systems (TCP/IP).
• Best practices and design patterns for modular, scalable, and maintainable robotics software that other teams can build upon.
• Seamless integrations between software components, creating a cohesive and reliable runtime environment.
• High-performance, real-time systems capable of operating in demanding and mission-critical scenarios.
• A culture of technical excellence by mentoring other engineers in architectural principles and software craftsmanship.
• Robust and secure systems through rigorous testing, validation, and a deep understanding of system-level details.
• Clear technical documentation that empowers your team and accelerates the development of new capabilities.

• Significant experience in software engineering, with deep expertise in both C++ and Python, ideally within regulated industries like defense, automotive, or aerospace.
• A profound understanding of modular software architecture, clean code principles, and designing for long-term maintainability.
• Hands-on experience building, debugging, and optimizing multithreaded, real-time, or performance-critical systems.
• A strong grasp of parallel and distributed systems, including low-level system profiling.
• Comfort and proficiency working in embedded environments such as Linux or QNX.
• Deep knowledge of system-level APIs (IPC, sockets, I/O) and communication protocols like CAN or Ethernet.
• Exceptional communication skills and the ability to lead technical discussions and collaborate effectively across teams.
• Familiarity with Bazel, zero-copy middleware, or lock-free programming is a strong advantage.
