Senior Robotics Software Engineer (State Estimation & Navigation)Autonomous Systems | Localization & Navigation | C++ Software DevelopmentFull-Time |On-Site | 5+ Years Experience Diversified Services Network, Inc. (DSN) is seeking a full-time Senior Robotics Software Engineer (State Estimation & Navigation) to join our team in Mossville, IL! We offer full benefits, PTO, 401k, and more! If you are a passionate robotics software engineer ready to build production-grade localization solutions for autonomous systems within an extremely reputable, stable Fortune 500 company — let’s talk! Position OverviewWe are seeking a Senior Robotics Software Engineer to join a new addition to our localization team, fully on-site in Mossville, IL. You will focus on software development for positioning and localization — prototyping and bringing to production algorithms that enable autonomous and semi-autonomous systems to localize robustly within their environment. This includes estimating position and altitude absolutely and relative to terrain features and static or mobile equipment, implementing filters using perception-based, inertial, and GNSS inputs. You will work within a technical team led by an Architect and Program Manager, collaborating with and mentoring fellow localization team members. Work is primarily office-based with occasional time in labs or at the Proving Grounds.
