Calibration and Localization Engineer

About Humble Robotics Working at Humble Robotics means taking on the biggest change in ground transportation in decades. We're building an autonomous, zero-emissions hauler that dramatically lowers the cost of freight with groundbreaking vision-based AI, designed for today's global logistics network. We're a fast-moving, close-knit team of AV industry veterans and innovative thinkers. We don't believe culture can be engineered – but when it falls into place, it's a once-in-a-lifetime adventure. Progress has never felt so present.

We're looking for an engineer to own the spatial foundations of our autonomy stack: how our sensors relate to each other and to the vehicle, and how that information is fused into a continuous, trustworthy estimate of where the vehicle is. The environments our trucks operate in, including port terminals, container yards, warehouses, and the corridors that connect them, all present unique challenges to both. This is a role for someone who thinks about sensor geometry and state estimation as facets of the same problem.

Lead the extrinsic calibration of our sensor suite and the localization algorithms that consume its outputs, ensuring both are robust, well-characterized, and evolve together

Develop evaluation frameworks and metrics that let us measure calibration and localization quality honestly across fleet data

Debug failures in real-world logs and translate findings into algorithmic improvements

Collaborate with Autonomy, vehicle software, fleet operations, and data teams to tighten the loop between these foundational systems and their downstream consumers

Contribute to the broader shape of how Humble approaches sensor geometry and state estimation as the team and fleet grow

BS, MS, or PhD in Robotics, Computer Science, or a related field — or equivalent industry experience

Strong foundation in the geometry, state estimation, and optimization methods: nonlinear optimization, Kalman filtering, factor graphs, sensor modeling, and similar

Hands-on experience contributing to production-grade calibration and/or localization systems

Proficiency in Python and Rust for developing algorithms and the tooling around them

Comfortable reasoning about uncertainty — both characterizing outputs and tracing propagation to downstream systems

Eligible to work in the United States

Experience with online or continuous calibration, where calibration updates feed live into localization

Experience building evaluation frameworks at fleet scale, outside controlled lab environments

Familiarity with the failure modes of INS/GNSS in challenging environments, and techniques for handling them

Comfort with modern build and dev environments (Bazel, monorepos, dev containers, or similar)

Comfort operating as an early team member — high ownership, low ego, fast iteration

This role is eligible for base salary + benefits + equity compensation. Salary ranges are determined by role, level, and location. Within the range, individual pay is determined by additional factors, including qualifications, skills, experience, and location.

As part of the interview process, we may use Artificial Intelligence (AI) tools to compare your qualifications and experience to the job description.
