About us
42dot is a mobility AI company committed to solving mobility challenges with software and AI. As the Global Software Center of Hyundai Motor Group, 42dot pioneers the future of mobility by advancing the development of software-defined vehicles. We develop safety-first, user-centric software-defined vehicle technologies that deliver the latest performance through continuous updates like smartphones. By advancing software and AI technology, 42dot envisions a world where everything is connected and moves autonomously through a self-managing urban transportation operating system.
About The Role
ML-first does not mean ML-only: every model this team ships depends on a vehicle that knows precisely where its sensors are, where it is in the world, and how confident it can be in both. This role owns that foundation, building the calibration, mapping, and localization stack that every perception and planning model is built on top of, across a multi-vehicle-class fleet spanning passenger vehicles, robotaxis, buses, and trucks.
Founding team Opportunity
Most Autonomy Programs Set Their Calibration And Localization Architecture Years Ago And Are Now Stuck Maintaining It. This Team Is Establishing Its Framework Now, And An Early Hire Will Help Shape:
- Sensor calibration methodology and tooling, both online and offline
- Mapping strategy, representation, and drift-detection pipelines
- Localization architecture and the technical roadmap as the fleet scales
Responsibilities
- Design and implement sensor calibration systems (camera, LiDAR, radar, IMU) for factory and in-field use
- Build and maintain mapping pipelines, including map creation, versioning, and drift detection
- Develop and improve localization algorithms, including sensor fusion, odometry, and SLAM
- Define accuracy, latency, and reliability requirements for outputs consumed by downstream teams
- Build tooling to validate calibration and localization quality at fleet scale
- Diagnose and resolve calibration and localization failures from on-road and simulation testing
Qualifications
- A demonstrated ability to work through difficult technical problems methodically, with growing independence
- Bachelor's or Master's degree in Computer Science, Robotics, EE, Mathematics, or related field
- 2-4 years of experience in sensor calibration, SLAM, mapping, localization, or multi-sensor fusion
- Working knowledge of estimation theory, including Kalman filters, factor graphs, or optimization-based fusion
- Solid software engineering skills in C++ and/or Python, with experience contributing to production-grade robotics systems
Preferred Qualifications
- Exposure to autonomous driving or robotics across multiple vehicle classes
- Exposure to HD map creation and maintenance pipelines
- Experience with LiDAR, camera, or radar extrinsic calibration
- Familiarity with functional safety requirements such as ISO 26262

Get Access To All JobsTips for Finding OPT Sponsorship as a Calibration Technician
Confirm your degree qualifies for STEM OPT extension
Calibration Technician roles typically qualify under engineering technology or physical sciences CIP codes. Verify your degree program appears on the STEM OPT designated degree list before targeting employers, so you can confidently offer 36 months of work authorization.
Target industries with established OPT hiring pipelines
Aerospace, defense contractors, medical device manufacturers, and industrial equipment firms hire calibration technicians regularly and often have HR teams familiar with OPT paperwork. These sectors are more likely to absorb the administrative overhead of sponsoring work authorization than smaller shops.
Highlight ISO and ANSI calibration standards in your application
Employers evaluating OPT candidates weigh technical readiness heavily. Proficiency with ISO 17025, ANSI Z540, or specific measurement instruments like oscilloscopes and torque analyzers signals you can contribute immediately, reducing perceived risk around your temporary work authorization status.
Address OPT timing proactively with hiring managers
Calibration roles often have longer onboarding cycles due to equipment training. Clarify your OPT start date and remaining authorized period upfront so employers can plan around your timeline and begin H-1B visa sponsorship conversations well before your authorization expires.
Pursue employers registered for E-Verify
STEM OPT extensions require your employer to be enrolled in E-Verify. Confirm this before accepting an offer. Most large manufacturers and government contractors are already enrolled, but smaller calibration labs or independent metrology firms may not be.
Obtain relevant certifications before your job search
Credentials like ASQ Certified Quality Technician or manufacturer-specific metrology training strengthen your candidacy and reduce employer hesitation about sponsorship costs. Certified candidates are easier to justify hiring on OPT when the technical value is demonstrably clear.
Calibration Technician OPT: Frequently Asked Questions
Does a Calibration Technician job qualify for the STEM OPT extension?
It depends on your degree, not the job title. If your degree is in engineering technology, electrical engineering, physics, or a closely related STEM field listed on the DHS STEM designated degree program list, you qualify for a 24-month STEM OPT extension on top of your standard 12 months. The job itself must also be directly related to your degree program.
How do I find Calibration Technician jobs that sponsor OPT?
Migrate Mate is built specifically for F-1 OPT students and filters jobs by sponsorship willingness, so you are not wasting applications on employers who won't work with OPT candidates. Calibration and metrology roles in aerospace, defense, and manufacturing appear regularly. Searching by STEM field on Migrate Mate will surface the most relevant opportunities.
What should I include in my resume when applying for Calibration Technician roles on OPT?
List your OPT authorization period and whether you qualify for the STEM extension. Include specific instruments you have worked with, such as CMMs, multimeters, pressure gauges, or torque wrenches, along with familiarity with calibration standards like ISO 17025 or ANSI Z540. Employers want to see technical readiness alongside a clear picture of your work authorization timeline.
Can I start a Calibration Technician job before my STEM OPT extension is approved?
Yes, under certain conditions. If you file your STEM OPT extension application before your standard OPT expires, you receive an automatic 180-day cap-gap that lets you continue working. You cannot start a new job during this period without an active OPT EAD, so time your application carefully and confirm your employer is enrolled in E-Verify before filing.
What happens if my Calibration Technician employer cannot sponsor an H-1B after my OPT ends?
OPT work authorization is time-limited, and not every employer will pursue H-1B sponsorship. If your current employer cannot sponsor you, your options include finding a new employer who will file an H-1B petition on your behalf, exploring other visa categories like the O-1 visa if you have exceptional credentials, or returning to school for a higher degree to restart your OPT clock.
