Get Access To All JobsRole: Senior Simulation Engineer
Location: Mountain View, CA (Hybrid Onsite)
Job Type: W2 Contract
We are seeking a highly skilled Senior Simulation Engineer to own and accelerate our synthetic data generation capabilities. This role is crucial for bridging the gap between our high-fidelity simulation environment and our production ML models. You will be responsible for architecting, implementing, and maintaining the entire simulation-to-data pipeline, ensuring a consistent and massive flow of quality training data.
Key Responsibilities
- Simulation Acceleration & Data Collection: Directly utilize expertise in NVIDIA Isaac Sim to design, script, and optimize simulation scenarios specifically tailored to generate high-quality, diverse data for VLA (Vision-Language Alignment) and NOVA model training objectives.
- Pipeline Architecture: Design, build, and maintain robust, scalable pipelines for CAD ingestion, scene creation, sensor emulation, and data processing within the Isaac Sim framework.
- Synthetic Data Management: Implement and manage advanced auto-annotation tools within the simulation environment to rapidly label complex sensory data (e.g., 3D bounding boxes, semantic segmentation, depth maps) for supervised learning.
- Environment Maintenance: Take ownership of setting up, configuring, and maintaining the simulation environment (including hardware/software dependencies, GPU utilization, and headless operation) to ensure reliable, large-scale parallel execution.
- Cross-Functional Support: Collaborate closely with the Machine Learning Engineering team to analyze data gaps, iterate on simulation parameters, and ensure the synthetic data distribution matches the necessary complexity and variability of real-world deployment.
- Performance Tuning: Profile and optimize simulation execution speed to maximize data throughput, essential for rapid iteration cycles in model tuning.
Required Qualifications
- Expertise in Simulation: 3+ years of hands-on experience with NVIDIA Isaac Sim (or a comparable high-fidelity physics simulator like Unity/Unreal used for robotics).
- Programming Proficiency: Expert-level proficiency in Python for scripting, automation, data pipeline construction, and tool development.
- Robotics Fundamentals: Strong understanding of robotics kinematics, sensor physics (LIDAR, RGB-D cameras, IMU), and their accurate representation in simulation.
- ML Data Pipeline Experience: Proven experience setting up automated data collection pipelines for Deep Learning projects, including experience with data versioning and metadata management.
- CAD/3D Workflow: Familiarity with 3D assets, CAD formats, and procedural generation techniques to create complex virtual scenes.
Preferred Qualifications
- Familiarity with VLA/NOVA model architectures or similar foundation models in robotics.
- Experience with cloud computing environments (AWS, Azure, GCP) for scaling simulation jobs.
- Familiarity with other robotics simulation/middleware like ROS/ROS 2.
- Experience with hardware-in-the-loop (HIL) or software-in-the-loop (SITL) testing methodologies.

Get Access To All JobsTips for Finding H-1B Visa Sponsorship as a Senior Simulation Engineer
Map your degree to simulation SOC codes
USCIS evaluates specialty occupation by matching your degree field to the role's SOC code. Pull the O*NET profile for your target job title to confirm the listed education requirements before applying, so your credentials align precisely with what adjudicators expect.
Target defense and aerospace primes first
Companies holding large government contracts in aerospace, defense, and automotive simulation file LCAs consistently to meet project staffing demands. Filtering by industry sector narrows your search to employers with active, recurring H-1B filing histories rather than one-off sponsorships.
Search verified H-1B sponsors on Migrate Mate
Use Migrate Mate to filter Senior Simulation Engineer openings by employers with confirmed H-1B LCA filing history. This removes roles at companies that advertise sponsorship but lack a documented DOL filing record for simulation or engineering positions.
Verify prevailing wage before negotiating your offer
Run your job title and work location through the OFLC Wage Search before salary discussions. Your offer must meet the DOL prevailing wage for your level, and knowing the wage tier in advance prevents you from accepting a number that fails the LCA certification threshold.
Confirm E-Verify enrollment before your start date
If your H-1B transfers from OPT or a prior employer, your new employer must be enrolled in E-Verify to complete I-9 verification. Confirm enrollment during the offer stage, not after you've given notice, to avoid a gap that delays your authorized start date.

Find Senior Simulation Engineer JobsSenior Simulation Engineer H-1B Visa: Frequently Asked Questions
Do Senior Simulation Engineer roles qualify as H-1B specialty occupations?
Yes. USCIS consistently classifies simulation engineering as a specialty occupation because the role requires at least a bachelor's degree in a directly related field such as mechanical, aerospace, electrical, or systems engineering. The O*NET profile for simulation and modeling engineers supports this classification, and most petitions in this field clear the specialty occupation threshold without an RFE when the degree field closely matches the job duties.
Which industries sponsor H-1B visas most frequently for simulation engineers?
Defense contractors, automotive OEMs, aerospace manufacturers, and semiconductor companies file the highest volume of LCAs for simulation engineering roles. These industries run large-scale modeling and simulation programs that require sustained staffing, making them more likely to maintain active H-1B sponsorship pipelines. Use Migrate Mate to browse Senior Simulation Engineer openings filtered by employers with verified LCA filing history in these sectors.
How does the H-1B cap lottery affect hiring timelines for simulation engineers?
Most simulation engineers targeting private-sector employers are subject to the standard H-1B cap of 65,000 regular slots plus 20,000 for U.S. master's degree holders. USCIS opens registration in March each year, with a lottery if registrations exceed the cap. If you're selected, employment can't begin before October 1. Some simulation roles at universities or non-profit research labs are cap-exempt, allowing year-round filing with no lottery.
Can I transfer my H-1B to a new simulation engineering employer mid-project?
Yes, H-1B portability under AC21 lets you start working for a new employer as soon as the transfer petition is filed with USCIS, without waiting for approval, provided your original petition was approved and you've maintained valid status. Your new employer must file a new I-129 and LCA before your first day. Confirm the new employer's E-Verify enrollment and ensure the new role still qualifies as a specialty occupation under your degree field.
What happens to my H-1B status if my simulation project ends and I'm between contracts?
H-1B status is employer-specific, so losing the role tied to your petition puts you in a 60-day grace period to find a new sponsoring employer, change status, or depart the U.S. Your employer must file an I-129 transfer petition before the grace period expires to maintain your authorization. Defense and aerospace simulation roles can have contract-driven gaps, so lining up your next opportunity before project close reduces the risk of a status lapse.
