Your Role
Key responsibilities in your new role
- Support customers and partners on-site and remotely: joint debug, integration sessions, and structured problem reproduction for digital-twin and simulation workflows involving Infineon solutions
- Benchmark simulation-to-reality (sim-to-real) behavior: define metrics, test vectors, and reporting so teams can trust—or improve—their simulation fidelity
- Study and apply leading robotics simulation and training stacks—including Isaac Sim, Isaac Lab, and Omniverse where customers standardize on them—and clarify compute, licensing, and pipeline implications for customer projects
- Specify and document software APIs, extension points, and interface requirements so Infineon modules (for example tactile, time-of-flight) integrate cleanly into customer digital-twin and simulation environments
- Build or adapt reference snippets, small tools, and example flows (for example in Python or C++) to accelerate customer integration—without replacing the customer’s ownership of their system
- Work with sensor and actuator modeling in simulation where relevant: noise, calibration concepts, timing, and data formats that affect learning and controls
- Partner with ROS2-oriented customer stacks when applicable (bridges, message contracts, sim time vs wall time)
- Communicate clearly with engineering and program stakeholders: written summaries, demos, and occasional training or workshop segments for customers
- Coordinate with colleagues across sites (Americas, Europe, and central teams) to align on priorities, reuse integration assets, and escalate product or documentation gaps
- Stay current on Physical AI, humanoid and industrial robotics, and edge-AI trends that affect how customers use digital twins for development and validation.
Your Profile
Qualifications and skills to help you succeed
- Education: Bachelor’s, Master’s, or PhD in Computer Science, Electrical Engineering, Robotics, Mathematics, Applied Mathematics, or comparable field—with a strong software focus.
Experience: 4 to 6 years of professional experience in software, robotics, simulation, embedded systems, or closely related integration roles—or about 2 years of relevant experience combined with a Master’s or PhD. Final Global Grade follows job content, not a rigid years rule
- Demonstrated skill in Python and C++ for integration, tooling, or performance-relevant code paths.
Hands-on exposure to physics-based robotics simulation, digital twins, or ML/RL training loops in industry, research, or high-quality open-source projects

Get Access To All JobsTips for Finding OPT Sponsorship as a Principal Engineer
Lead with architectural impact, not just technical skill
Principal Engineers are hired to make system-level decisions, not just write code. Frame your experience around architectural tradeoffs you owned, systems you designed end-to-end, and the business outcomes those decisions drove at scale.
Confirm your role qualifies under STEM OPT
Principal Engineer positions in software, hardware, or systems engineering almost always qualify for the 24-month STEM OPT extension. Verify your degree field matches the DHS STEM designated degree list before applying to extend your authorization window.
Target companies with established H-1B sponsorship track records
Senior technical roles are among the most commonly sponsored positions. Prioritize employers with a history of filing H-1B visa petitions for principal-level engineers, since they already have internal processes and legal counsel to support your transition off OPT.
Use your OPT timeline as a negotiating asset, not a liability
Employers hiring at the principal level are investing in long-term technical leadership. Framing your OPT status alongside your H-1B eligibility signals continuity. Most companies at this level expect to sponsor and will factor that into the offer process.
Demonstrate cross-functional ownership in your interviews
Principal Engineers are evaluated on how they align engineering decisions with product and business goals. Come prepared with examples of driving consensus across teams, influencing roadmaps, and navigating organizational complexity, not just technical problem-solving.
Time your job search around your OPT expiration and extension deadlines
Apply at least four to six months before your OPT end date. If you are pursuing a STEM extension, your employer must enroll in E-Verify. Confirming this early prevents gaps in work authorization that could disrupt onboarding at the senior level.
Principal Engineer OPT: Frequently Asked Questions
Can I work as a Principal Engineer on F-1 OPT?
Yes. F-1 OPT authorizes you to work in any role directly related to your degree field, and Principal Engineer positions in software, systems, or hardware engineering qualify for most STEM-aligned degrees. If your degree is on the DHS STEM designated list, you're also eligible for a 24-month STEM OPT extension, giving you up to three years total.
Do Principal Engineer roles qualify for the STEM OPT extension?
Principal Engineer roles in software engineering, computer science, electrical engineering, and related fields almost always qualify for the STEM OPT extension. The key requirements are that your degree appears on the DHS STEM designated degree list, your employer is enrolled in E-Verify, and the job is directly related to your field of study. Most Principal Engineer positions at tech companies meet all three criteria.
How hard is it to find a Principal Engineer job that offers H-1B sponsorship?
Principal Engineer is one of the most sponsorship-friendly titles in tech. Employers hiring at this level are making a long-term investment in technical leadership, and most established tech companies already have H-1B sponsorship infrastructure in place. You can browse Principal Engineer roles filtered by OPT and H-1B sponsorship on Migrate Mate to focus your search on employers actively open to sponsoring international candidates.
What degree do I need to qualify for Principal Engineer OPT jobs?
Most Principal Engineer roles require a bachelor's degree at minimum in computer science, computer engineering, electrical engineering, or a related technical field. A master's degree is common at this level, particularly at larger companies with defined engineering ladders. Your degree field needs to have a direct relationship to the job duties, which is straightforward for most engineering disciplines at this seniority level.
What should I do if my OPT expires before my H-1B is approved?
If you filed your H-1B petition before your OPT expired and your employer submitted on time for an October 1 start date, you may be eligible for a cap-gap extension that bridges the period between OPT expiration and the H-1B start date. Your DSO can issue an updated I-20 reflecting cap-gap status, which allows you to continue working. Confirm your employer understands this process, since Principal Engineer roles often involve time-sensitive project ownership that makes gaps particularly disruptive.
