Employer immigration record

from this employer's Department of Labor filings

Green-card follow-through: 100%

Of 5 labor certifications old enough to have been used, 0 expired without the employer filing the next step. Median time from filing to decision: 513 days.100% of their filings were for a worker who already held the job.Only certifications past the 180-day window are counted — recent ones cannot have expired yet.

Files H-1B transfers

9 transfer filings in the last year, covering 9 workers. 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

  • About Redwood Materials Redwood is localizing a global battery supply chain that seamlessly integrates recovery, reuse, and recycling - keeping critical minerals in circulation and driving the energy transition.
  • The Software Validation team ensures that these complex systems are safe, resilient, and ready for grid-scale deployment.

Responsibilities

  • Validation Environment Design: Architect and scale our SIL and HIL environments (using platforms like Typhoon HIL, Opal-RT, or similar) to provide high-fidelity simulations of battery assets and grid conditions
  • Test Automation Frameworks: Lead the development of automated test suites in Python. You will transition our validation processes from manual intervention to a fully automated, scalable framework
  • Hardware-in-the-Loop Interfacing: Design custom interface hardware and wiring for HIL benches, bridging physical I/O from our controllers to simulated power stages

Requirements

  • Background: A BS or MS in Electrical Engineering, Computer Engineering, or a related field, combined with 2+ years of professional experience in software validation or test automation for hardware-focused systems
  • HIL/SIL Mastery: Proven experience with real-time simulation platforms ( Typhoon HIL, Opal-RT, or dSPACE ) and a deep understanding of how to model power electronics components in a virtual environment
  • Automation Toolchain: Expert proficiency in Python (specifically for test automation frameworks like Pytest) and familiarity with Rust and C/C++ to navigate embedded codebases
  • You have a track record of finding critical edge cases in complex state machines and control loops
  • Infrastructure: Experience with Git, Jenkins/GitHub Actio
  • As a Software Validation Engineer, you are the bridge between pure code and physical reality.
  • A BS or MS in Electrical Engineering, Computer Engineering, or a related field, combined with 2+ years of professional experience in software validation or test automation for hardware-focused systems
  • Proven experience with real-time simulation platforms ( Typhoon HIL, Opal-RT, or dSPACE ) and a deep understanding of how to model power electronics components in a virtual environment
  • Expert proficiency in Python (specifically for test automation frameworks like Pytest) and familiarity with Rust and C/C++ to navigate embedded codebases
  • Comfortable in a high-voltage lab environment.
  • You should be proficient with standard lab equipment (oscilloscopes, power supplies, electronic loads) and digital protocols like CAN, SPI, and Ethernet
  • A dedicated mindset for "breaking" software.
  • Experience with Git, Jenkins/GitHub Actio

Company info

  • Founded in 2017, we're delivering low-cost and large-scale energy storage and producing battery materials in the U.S. for the first time, all from batteries we already have.
  • The Redwood Vision: Architecting the Future of the Grid We are at the precipice of a global energy transition.
