Company

hirify.global builds foundational world models that perceive, generate, reason about, and interact with the 3D world through spatial intelligence.

What you will do

• Design and implement modern SLAM systems for visual, visual-inertial, lidar, and multi-sensor configurations.
• Develop localization and mapping pipelines covering pose estimation, map management, loop closure, and global optimization.
• Research learning-based and hybrid SLAM approaches combining classical geometry with machine learning.
• Build scalable state estimation frameworks using factor graph optimization, filtering, and smoothing.
• Develop sensor fusion strategies and analyze failure modes such as perceptual aliasing, dynamic scenes, and drift.
• Create evaluation benchmarks and optimize accuracy, robustness, memory usage, compute efficiency, and real-time performance for production systems.

Requirements

• 6+ years of experience in SLAM, state estimation, robotics perception, or related areas.
• Strong knowledge of probabilistic estimation, optimization, geometric vision, bundle adjustment, factor graphs, and Kalman filtering.
• Deep experience with visual, visual-inertial, lidar, multi-sensor, or hybrid SLAM systems.
• Proficiency in Python and/or C++ and experience building research or production-grade systems.
• Experience with numerical optimization libraries or robotics frameworks, plus understanding of sensor calibration, synchronization, and noise modeling.
• Ability to drive projects from concept through deployment in ambiguous, fast-moving environments.

Culture & Benefits

• Work with research scientists, ML engineers, systems teams, and infrastructure specialists on spatially intelligent AI systems.
• Collaborate in a small, high-caliber team focused on technical rigor, experimentation, and code quality.
• Base salary of $250,000–$350,000 plus equity awards.
• Equal opportunity employment with reasonable accommodations available throughout the hiring process.
