Senior Full Stack Software Engineer 

Based in Pasadena, CA 

OffWorld is a robotics startup working on developing a mobile robotic workforce for heavy industrial jobs on Earth, Moon, asteroids & Mars. OffWorld was founded by an experienced engineering team drawing on decades of tackling formidable engineering challenges at NASA, ESA, NOAA, Maxar Technologies, CERN, Reaction Engines, SAFRAN, Surrey Satellites and Cisco. OffWorld’s first challenge is developing and maturing a modular robotic system for extreme environments on Earth. Our robots will go deeper underground and farthest on Earth than humans can, eliminate the need for humans to work in life-threatening environments in mining, construction, tunneling and other dangerous industries, and dramatically reduce the environmental footprint and cost of operations in key economies on Earth and beyond.  

We have designed a modular robotic architecture that focuses on maximizing the commonality and reusability across components for fast deployment and optimization. Our robotic systems combine sensor information, cutting edge classical/machine learning (ML) algorithms and a robotics real-time system platform for control, decision making and execution.  

We are looking for a Senior Full Stack Software Engineer who will be responsible for the implementation of the real-time Software Platform architecture. You will be working with our Software Architect to implement key front and back-end functionality for the operation of our robots, including the user interface for swarm/multi-unit robot autonomous operations monitoring and exception management, data processing stack, fault detection, isolation and recovery handling, health management, process management, and other functions. 

You will have the unique opportunity of developing systems for high end robots working as a swarm in extreme environments. Your work will be instrumental to ensure effective swarm autonomous operations is achieved with maximum human visualization and minimal human intervention. You will work with the Mechatronics, Machine Learning and Robotics & Controls engineers to ensure interfaces to the firmware, controls and ML modules is seamless.  

Your work will entail both design and implementation of the full data processing layer for the real time operation of our swarm of robots, including telemetry, point cloud and other sensor related data processing. You will contribute to the design and implementation of intuitive interfaces (computer and smart pad displays, joysticks, and other types of interfaces) that can ensure low workload and maximum situational awareness for remote monitoring using low latency networking infrastructure. Experience with full stack software engineering for real time mobile app visualization is required. Human Centered Design and UX/UI design principles knowledge for effective operational decision making with minimum workload is a plus.  

To hit the ground running, you need: 

  • Bachelors or higher in Computer Science, Software Engineering or equivalent with at least 5 years of professional experience. 
  • Experience in the development of full stack solutions for applications in robotics, IOT, industrial, automotive or equivalent.  
  • Extensive experience in the design of core pieces of software architecture which address product requirements. 
  • Extensive experience in developing full-stack software components covering software running on mobile applications and browser-based front-end UI applications. Directly applicable experience in IoT, autonomous cars or robotics is a plus. 
  • Experience with the implementation of solutions for multiple platforms, such as computer, tablet and phone displays, as well as hybrid solutions (display and joystick, etc). VR/AR integration experience for the gamification of user interactions with specialized equipment is a plus. 
  • Experience in developing polished web applications using Javascript, React, NodeJS and other advanced web technologies.
