Senior/Staff Behavior Planning Engineer

We’re seeking Senior or Staff Engineers to help build the core behavior planning system for autonomous vehicles, enabling safe and intelligent decision-making. The role involves designing behavior tree architectures, developing robust C++ infrastructure, collaborating across autonomy teams, evaluating planner performance, and providing technical leadership within the team.

• Design, implement, and maintain the core behavior planning system for autonomous vehicles, enabling intelligent, interpretable, and safe decision-making in complex real-world scenarios.
• Develop and extend behavior tree architectures for hierarchical decision logic, including support for mission planning, tactical maneuvers, and contingency handling.
• Collaborate closely with the motion planning, prediction, and control teams to ensure seamless transitions from high-level decisions to executable trajectories.
• Build and optimize C++-based software infrastructure for behavior planning, including tools for simulation, debugging, visualization, and closed-loop testing.
• Evaluate planner performance in diverse real-world and simulated environments; identify failure modes and develop strategies to improve robustness and generalization.
• Participate in design reviews and system integration across the full autonomy stack.
• Provide technical leadership, mentorship, and architectural guidance for junior team members.

• Ph.D. with 3+ years or Master’s with 5+ years of industry experience in robotics, autonomous systems, or behavior planning.
• Proven experience in behavior planning, including use of behavior trees, finite state machines, or rule-based planners in autonomous driving or robotics applications.
• Strong proficiency in C++ with a deep understanding of performance, memory management, and software architecture in production systems.
• Solid understanding of motion planning and prediction interfaces, with experience building real-time, safety-critical systems.
• Knowledge of diffusion models and/or Vision-Language-Action (VLA) models is a strong plus.
• Strong debugging, system thinking, and collaborative communication skills.

Salary Range - $180,000- $260,000

Founded in 2017 by experts in autonomous vehicle technology, Gatik has rapidly expanded its presence to Mountain View, Dallas-Fort Worth, Arkansas, and Toronto. As the first and only company to achieve fully driverless middle-mile commercial deliveries, Gatik holds a unique and defensible position in the AV industry, with a clear trajectory toward sustainable growth and profitability.

We have delivered complete, proprietary AV technology - an integration of software and hardware - to enable earlier successes for our clients in constrained Level 4 autonomy.  By choosing the middle mile – with defined point-to-point delivery, we have simplified some of the more complex AV challenges, enabling us to achieve full autonomy ahead of competitors. Given extensive knowledge of Gatik’s well-defined, fixed route ODDs and hybrid architecture, we are able to hyper-optimize our models with exponentially less data, establish gate-keeping mechanisms to maintain explainability, and ensure continued safety of the system for unmanned operations.
