Sr. Software Engineer, Autonomy

About Mariana Minerals Mariana Minerals is a software-first, vertically integrated minerals company on a mission to supply the critical minerals powering modern energy, AI, and defense technologies. We’re reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making. About the Role We are hiring Sr. and Staff Software Engineers (Autonomy) to build the onboard and platform software that carries our fixed and mobile equipment from raw sensor data to safe, reliable motion. In this role you will own the software the rest of the autonomy stack runs on: sensor drivers and data pipelines on the vehicle computer, time synchronization and calibration, deployment and monitoring, the handoff of data from the fixed and mobile equipment to the cloud, simulation and test infrastructure, and the drive-by-wire interface and low-level control logic. You will carry work from design through implementation, simulation, and bench and field validation on real equipment at our mine sites, working hand in hand with our machine learning, hardware, controls, and mine operations teams. This is a hands-on, first-principles role for an engineer who wants to get people out of the pit and build the world’s first fully autonomous mines. What You’ll Do Build and maintain the onboard software stack for our autonomous mining vehicles, from sensor drivers through actuation commands, on industrial PCs that run in dust, vibration, and heat Own time synchronization and calibration across LiDAR, cameras, radar, IMU, and GNSS so perception and localization get data they can trust Build the pipelines that move sensor and telemetry data off the vehicle and into the cloud, including logging, recording, and labeling data for perception development and evaluation Build deployment, monitoring, and fault-management tooling so we can update and operate a fleet of vehicles without logging into each one, and so the system detects and responds to software, sensor, compute, and network failures Develop equipment simulations and test infrastructure, including replay of field logs, evaluation datasets, and vehicle models for acceleration, turning radius, and actuation latency Integrate with drive-by-wire systems and write the low-level control logic and safety layer that connect the autonomy stack to the vehicle, including degraded operating modes and e-stop behavior Work with our MineOS and mine operations teams so the autonomy system exposes the health, faults, and metrics operators need to run it safely What You’ll Bring Bachelor's degree in Computer Science, Computer Engineering, Robotics, Electrical, or related engineering discipline 5-8+ years building software for robots, vehicles, or other systems that act in the physical world Strong proficiency in C++ and/or Python, and experience with Linux and a robotics middleware such as ROS/ROS 2 Hands-on experience with sensor drivers, data pipelines, time synchronization, or calibration for LiDAR, cameras, radar, IMU, or GNSS Working knowledge of real-time and embedded systems, networking, and debugging across the software-hardware boundary Experience with simulation, logging and replay, or test and deployment infrastructure for robotics systems Experience in autonomous vehicles, robotics, automotive, or off-highway equipment strongly preferred Our culture is built on four principles: Everyone Gets Home Safe. We never put speed or cost ahead of people. Extreme Ownership. We take full responsibility for outcomes, relentlessly driving toward solutions. Engineer Out Requirements, then Automate. We simplify, optimize, and then automate for scale. Share Your Legos. We collaborate openly, share knowledge, and empower each other to build bigger, better solutions. Join us as we build the future of responsible mineral sourcing and supply!
