Job Description:
As a senior member within the Hivemind Perception team, you will join an ambitious effort to bring autonomy to the world through the rapid design, development, integration, test, and deployment of extensible software solutions to enable GPS-denied navigation, computer vision, object detection & tracking, and sensor fusion on autonomous platforms. You will bring a deep understanding of optimal state estimation, sensor integration, data fusion, statistical inference, and dynamics modeling as well as a wealth of professional experience developing software using modern C++ (11 or greater) to this role.
What you'll do:
- Enhance the multi-object tracking and/or navigation capabilities offered in the Hivemind Software Development Kit (SDK) product
- Develop state of the art algorithms relevant to GPS-denied navigation, SLAM, object detection & tracking, and sensor fusion across several operational domains (air, land, maritime, space)
- Write production-quality software in C++ that will be deployed to high-reliability autonomous systems, ensuring robustness, efficiency, and scalability.
- Develop and maintain comprehensive unit, integration, and system tests to validate your software
- Lead the planning and execution of design reviews to introduce new perception capabilities into the Hivemind SDK product
- Create and enhance modeling capabilities to simulate effects of sensor noise, environmental effects, and object/vehicle dynamics
- Elevate the performance of high-caliber, agile scrum teams by driving clarity and technical rigor into their feature delivery processes
- Mentor and guide peers and less experienced engineers, fostering technical excellence and high standards across the team
- Work in a fast-paced, collaborative, continuous development environment, enhancing analysis and performance benchmarking capabilities
Required qualifications:
- Typically requires a minimum of 10 years of related experience with a Bachelor’s degree; or 9 years with a Master’s degree; or 7 years with a PhD; or equivalent work experience.
- 5+ years of active software development experience using modern versions of C++ (11 or above)
- Proven expertise in object-oriented software design principles and their practical implementation
- Experience implementing advanced algorithms relevant to one or more of the following: object detection, object tracking, inertial/aided navigation, optimal state estimation (Kalman filtering, graph-based optimization), or sensor fusion.
- Strong Git and Linux development skills along with modern software development practices (e.g., CI/CD, test-driven development)
- A track record of technical leadership, with the ability to set and maintain high standards, guide teams through complex technical challenges, and collaborate effectively across multiple teams
- Demonstrated track record of delivering high-quality software to meet product design requirements under accelerated delivery schedules
Preferred qualifications:
- Experience working with or developing software under DO-178C or similar safety-critical software standards
- Experience modeling and integrating sensors related to perception and navigation with production software (E.g., IMUs, barometers, magnetometers, RGB cameras, infrared sensors, radars, ladars)
- A strong record of technical leadership supporting product-oriented R&D efforts relevant to autonomy, aerospace, military, or robotics applications
