Job Description

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!

We 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.

Key Contributions & Responsibilities

• Research, design, and develop production-quality C++ localization algorithms and software, including design documentation, coding, product quality assurance, and validation.
• Contribute to requirements generation and architecture design for the localization system.
• Implement and validate state estimation filters using perception-based, inertial, and GNSS inputs to enable robust localization in autonomous systems.
• Support functional safety software design and validation processes.
• Collaborate with and mentor localization team members; take ownership of moving ideas from prototype through to production.
• Identify and document problems, analyze risks and benefits of alternative approaches, and apply structured diagnostic tools to drive resolution.

Team Structure & Work Environment

• You will work within a technical localization team led by an Architect and Program Manager, collaborating closely with fellow software engineers focused on autonomous systems.
• Work environment is primarily office-based with occasional time in labs or at the Proving Grounds. This is a fully on-site role in Mossville, IL — remote work is not available for this position.
