Employer immigration record

from this employer's Department of Labor filings

Files H-1B transfers

1 transfer filing in the last year, covering 1 worker. Median labor-condition decision: 7 days. An employer that already files transfers is one that can take over an existing H-1B.

Sourced from Department of Labor LCA, PERM and prevailing-wage disclosure data. Employer matching is by name, so figures may be split across an employer's legal entities. Absence of a filing means none appears in our copy of the data, not that none exists.

About the role

  • Pivotal is the leader in the emerging market of electric Vertical Takeoff and Landing (eVTOL) aircraft.
  • Last year we announced our next-generation aircraft, the Helix, which is rapidly progressing toward general release and scalable production in 2026.
  • Mobility is one of the most highly-valued areas of modern technology investments.

Responsibilities

  • Develop and maintain cell and pack-level thermal, electrical, and performance models.
  • Support pack-architecture trades involving cell selection, packaging, cooling approaches, venting, sensing, and protection features.
  • Partner with the Battery Management System, electrical, and software teams on models, interfaces, diagnostics, and data quality.
  • Partner with mechanical engineers on thermal-management design, structural interfaces, installation constraints, and aircraft integration.
  • We design, develop, and manufacture light eVTOL aircraft and are renowned for the BlackFly aircraft the world's first light eVTOL to fly manned missions and enter the consumer market.
  • Efficient, compact, and simple, Pivotal aircraft are designed for a wide range of consumer, public service, and defense applications.
  • About the Job The Battery Engineering team at Pivotal is seeking a Senior Battery Systems Simulation & Validation Engineer to develop predictive battery models, define verification strategies, and correlate analytical results with laboratory and flight-test data.
  • This role will support cell and pack development for electric aircraft and will work across battery, aeromechanical, electrical, systems, manufacturing and flight-test teams.

Requirements

  • Bachelor's degree in Mechanical, Aerospace, Electrical, Chemical Engineering, or a related technical discipline.
  • Five or more years of relevant experience in battery modeling, simulation, validation, testing, or system development.
  • Strong understanding of lithium-ion cell behavior, heat transfer, battery-pack operation, and test-data interpretation.
  • Proficiency with MATLAB, Python, Simulink, or comparable engineering analysis tools.
  • Experience with CFD, thermal-network modeling, electrothermal modeling, or multiphysics tools such as STAR-CCM+, ANSYS, Simcenter, or COMSOL.
  • Experience defining verification activities and producing clear technical documentation.
  • If you are ready for adventure, we invite you to join our amazing team and grow with us.
  • Experience developing equivalent-circuit and thermal models of lithium-ion cells and packs.
  • Experience developing and validating engineering models against measured data.
  • Strong analytical, troubleshooting, and cross-functional communication skills.

Nice to have

  • Experience with electric aircraft, electric vehicles, UAVs, aerospace systems, or other high-power battery applications.
  • Experience with battery-aging, degradation, state-estimation, or mission-performance models.
  • Exposure to battery abuse testing, thermal-runaway analysis, and propagation-mitigation concepts.
  • Familiarity with aerospace verification, environmental qualification, requirements management, and configuration control.
  • Experience with high-voltage battery systems and battery-management-system data.
  • Uses first- principles reasoning while remaining pragmatic about schedule, hardware, and available evidence.
  • Is equally comfortable working independently on analysis and collaborating at the test article or aircraft.
  • Communicates assumptions, uncertainty, correlation quality, and technical risk clearly.

Benefits

  • Analyze battery degradation, state of charge, state of health, energy capability, power capability, and thermal margins.

Company info

  • Our distinctive tilt-aircraft architecture and scalable platform have been flying for over 10 years.
