Green Card Test Engineer Jobs
Test Engineer roles qualify for employment-based green card sponsorship under EB-2 or EB-3, with employers filing PERM labor certification to demonstrate no qualified U.S. workers are available. Quality assurance and test engineering positions regularly appear in PERM filings across software, hardware, and manufacturing sectors, making this a viable path to permanent residency.

Hardware Test Engineers at Lunar Energy play a critical role in helping our engineering team decide whether our home energy products are ready to ship, and own the evidence behind that call. You'll design and automate the test stands that collect critical product performance data and analyze that data to work out the "so what." An ideal candidate is curious, hands-on, and comfortable working across electrical, mechanical, thermal, and software disciplines.
Lunar Energy was founded to transition homes to 100% clean energy—making our electricity greener, our air cleaner and our energy more safe, secure and reliable for all. We're a fast-growing, global company building the world's best clean energy products to electrify all homes and connect communities to form clean, resilient virtual power plants.
On a given day at Lunar, you'll likely…
- Be a critical part of validating Lunar's power converters (inverters, DC-DC converters, solar optimizers) and battery systems end to end: test planning, test stand development, execution, data analysis, failure analysis, and reporting.
- Help develop test specifications from the ground up that reflect representative field conditions. Translate field data, product behavior, and known failure modes into stress profiles that target the product's physics of failure.
- Develop detailed functional test plans that cover a complex product's many functions, balancing thoroughness against scalability across large sample sizes.
- Design and develop custom test stands for electrical, thermal, and mechanical testing.
- Define test stand architecture, specify equipment and instrumentation, and work with technicians to design and fabricate the stands.
- Write Python test software to automate testing and process large datasets.
- Continuously improve test infrastructure, from software tools to custom test equipment, to help us get more data and insight with less effort.
- Help drive failure analysis for test failures, and support root cause analysis for field failures.
- Analyze test data and FA results for root cause analysis, and help determine the next critical piece of data or experiment to prove or disprove a failure hypothesis.
- Document and communicate test results to cross-functional teams with conclusions, test limitations/caveats, confidence levels, and engineering recommendations. Treat testing as a learning process to understand the physics behind product performance.
- Work alongside a cross-functional team and learn across disciplines (electrical, mechanical, firmware, manufacturing, and more) to work out how different design and process changes affect reliability, and subsequently our validation strategy.
Desired Skills:
- Bachelor's degree in electrical engineering, mechanical engineering, or engineering physics required; mechatronics/robotics concentration is a plus
- Strong sense of curiosity and ownership, ability to work in a dynamic and fast paced environment
- Strong engineering fundamentals in one or more of the following disciplines: electronics/circuit analysis, heat and mass transfer, and statics/mechanics of materials
- Experience with electrical test equipment (power supplies, data acquisition systems) and standard diagnostic tools (multimeters, oscilloscopes) required
- Python or equivalent programming experience required; experience with object-oriented programming, state machines, and test automation is a plus
- Basic mechanical design or CAD experience is a plus
- Experience testing power electronics or battery systems is a plus

Get Access To All JobsTips for Finding Green Card Sponsorship as a Test Engineer
Document your specialized testing credentials early
Gather certifications like ISTQB, CSTE, or domain-specific QA credentials before the PERM process begins. USCIS scrutinizes whether your qualifications match the job requirements listed in the labor certification, so a credential gap can stall your I-140.
Target employers with active PERM filing histories
Search DOL's OFLC disclosure data for employers who have filed PERM applications for test engineer or quality assurance roles. Companies that have sponsored these positions before already understand the process, which shortens your negotiation around sponsorship timelines.
Clarify EB-2 versus EB-3 eligibility with your employer
If your role requires only a bachelor's degree, most employers file under EB-3. Candidates with a master's or substantial specialized expertise may qualify under EB-2, which matters for priority date backlogs depending on your country of birth.
Use Migrate Mate to filter sponsoring employers by role
Search for test engineer positions on Migrate Mate to find employers with documented green card sponsorship history. You can filter specifically for PERM-sponsoring companies rather than sifting through listings where sponsorship is unconfirmed or offered only for H-1B visa.
Align your job description language with PERM requirements
Employers must post the exact job duties from your PERM application during the supervised recruitment phase. Work with HR to ensure your daily responsibilities, testing methodologies, and tools match the labor certification language before the filing is submitted to DOL.
Understand the PERM recruitment window before accepting an offer
DOL requires employers to complete a mandatory recruitment period, including job postings and applicant review, before certifying a PERM. This process typically adds several months before USCIS even receives your I-140, so factor that into your current status timeline.
Green Card Test Engineer: Frequently Asked Questions
Does a Test Engineer role qualify for EB-2 or EB-3 green card sponsorship?
Most test engineer positions qualify under EB-3 as skilled workers requiring a bachelor's degree in computer science, electrical engineering, or a related field. If the role requires an advanced degree or you have specialized credentials that clearly exceed the minimum, your employer may file under EB-2 instead. Your country of birth affects which category is strategically faster due to priority date backlogs.
How does green card sponsorship differ from H-1B for a Test Engineer?
Green card sponsorship through PERM and I-140 leads to permanent residency rather than a temporary work authorization tied to a specific employer. Unlike H-1B, employment-based green cards have no annual lottery, though EB-2 and EB-3 categories have per-country caps that create backlogs for applicants born in India or China. The overall process takes longer, but the outcome is permanent status rather than a visa requiring renewal.
What does the PERM labor certification process involve for Test Engineer roles?
Your employer files a PERM application with DOL certifying that no qualified U.S. workers were available for the position. This requires a supervised recruitment period, including job postings, applicant review, and documented rejection reasons. The job duties and minimum requirements in the PERM must accurately reflect the role you'll perform, and any mismatch can trigger an audit or denial from DOL.
Where can I find Test Engineer jobs that offer green card sponsorship?
Use Migrate Mate to search specifically for test engineer positions at employers with confirmed PERM or employment-based green card filing history. Most general job boards don't surface sponsorship status reliably, and many listings that say 'we sponsor visas' mean H-1B only. Focusing your search on employers with documented PERM filings saves time and avoids late-stage surprises when you raise the green card conversation.
Can I switch employers after my I-140 is approved but before I receive my green card?
Yes, under AC21 portability rules, you can change employers after your I-140 has been approved for 180 days or more, provided the new role is in the same or a similar occupational classification. For test engineers, moving between QA roles in software, hardware, or manufacturing generally satisfies the 'same or similar' standard, but you should confirm the occupational classification aligns before making the switch.
