Software Engineer, II - Calibration

Ann Arbor, MI

About the Company

At Torc, we have always believed that autonomous vehicle technology will transform how we travel, move freight, and do business.

A leader in autonomous driving since 2007, Torc has spent over a decade commercializing our solutions with experienced partners. Now a part of the Daimler family, we are focused solely on developing software for automated trucks to transform how the world moves freight.

Join us and catapult your career with the company that helped pioneer autonomous technology, and the first AV software company with the vision to partner directly with a truck manufacturer.

Meet the Team 

The Sensor Calibration team at Torc plays a vital role in ensuring the accuracy and reliability of perception systems across our autonomous vehicle platform. We develop and maintain software tools and algorithms that calibrate and validate multi-modal sensors including cameras, Lidar, and IMUs—both in simulation and on real vehicles. Our work directly supports the safety, performance, and robustness of autonomous driving capabilities. 

What You’ll Do 

  • Design and implement scalable sensor calibration pipelines in Python and C++, leveraging OpenCV, ROS, and linear algebra libraries for real-time and offline calibration. 
  • Develop tools to perform and automate camera intrinsic calibration, Lidar-to-camera, and IMU-to-camera extrinsic calibration. 
  • Apply mathematical rigor using Lie groups, quaternions, and 3D transformations to support accurate calibration and registration. 
  • Build and maintain simulation tools and data pipelines for sensor modeling and calibration validation. 
  • Work closely with perception, simulation, and platform teams to ensure calibration accuracy across hardware configurations and software versions. 
  • Utilize Docker, Bazel, and Git to develop reproducible, containerized calibration workflows integrated into CI/CD pipelines. 
  • Debug sensor alignment issues in vehicle logs and simulation using ROS tools, rviz, and custom visualizers. 

What You’ll Need to Succeed 

  • Bachelor’s Degree in Computer Science, Robotics, Electrical Engineering, or a related field with 3–5 years of experience (or a Master’s Degree with 1–2 years of experience). 
  • Proficiency in Python and C++ for tool development and algorithm implementation. 
  • Experience with OpenCV, ROS, and numerical libraries for computer vision and robotics. 
  • Experience working with sensors and sensor data across multiple modalities. 
  • Strong understanding of camera intrinsic/extrinsic models, sensor alignment, and coordinate frame transformations. 
  • Familiarity with Lidar, IMU, and multi-sensor calibration, especially in robotics or autonomous systems. 
  • Solid grasp of 3D geometry, non-linear optimization, and matrix math, including SE(3) and SO(3) representations. 
  • Comfort working in Linux development environments, using Git, Docker, and command-line tools. 

Bonus Points! 

  • Experience with Rust or interest in learning it for high-performance tooling. 
  • Familiarity with non-linear least squares solvers (e.g., Ceres, g2o). 
  • Background in sensor simulation for synthetic data generation and validation. 
  • Contributions to ROS-based open-source calibration tools. 
  • Uses vim as a primary editor (yes, really). 
  • Willingness to travel on occassion.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
