H-1B wage level

the lottery is wage-weighted — each level is one more entry

Level III$193,1493 entries
Level IV$221,1874 entries

$13,131 more$165,131 — moves this role to Level II and 2 lottery entries. That figure is inside the range the employer already advertised.

Based on the DOL prevailing wage for this occupation and worksite, a base salary of $165,131 would place this position at wage Level II. That figure is within the posted range, and I'd like to target it. This role classifies under "Software Developers" for prevailing-wage purposes.

DOL prevailing wage, 2026-27 wage year · Software Developers (15-1252) · San Francisco-Oakland-Fremont, CA. Wage level is derived by USCIS from the offered wage, occupation and worksite; the occupation shown is inferred from the job title.

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.

About the role

  • At Redwood, we are architecting the future of grid-scale energy storage and circular energy ecosystems.
  • This role focuses on moving away from rigid, hardware-centric infrastructure toward a resilient, unified, and software-defined energy storage architecture.
  • Proven track record in controls and software engineering with a deep, practical understanding of lithium-ion battery architectures, external BMS software, and pack-level integration.

Responsibilities

  • Technical OEM Partnerships: Be the lead engineering voice bridging the gap between legacy automotive hardware and modern software infrastructure.
  • Dive into the technical weeds with tier-1 suppliers to decode firmware, negotiate engineering solutions, and build the software handshakes that make second-life integration a reality.
  • Architectural Integration: Design and deploy translation layers and software gateways to seamlessly integrate vendor-off-the-shelf and second-life OEM battery packs into our centralized energy storage system.
  • Modern Software Development: Develop robust, containerized applications to handle external BMS communication, data parsing, and fault management utilizing modern technologies like Rust and Python within Linux environments.
  • System Resilience: Build highly resilient communication interfaces (CAN, Ethernet, Modbus) capable of dynamically handling the idiosyncrasies and proprietary logic of different OEM packs without compromising overall system stability.
  • Cross-Functional Collaboration: Partner closely with power electronics, site controller, controls teams, and our internal BMS developers to ensure safe, optimized, and harmonized operation of integrated modules within the broader BESS architecture.
  • Validation & Testing: Drive rigorous validation across simulation tools, Hardware-in-the-Loop (HIL) platforms, and physical battery hardware to verify OEM BMS behavior, safety boundaries, and control algorithms under novel off-vehicle duty cycles.
  • Design and deploy translation layers and software gateways to seamlessly integrate vendor-off-the-shelf and second-life OEM battery packs into our centralized energy storage system.
  • Build highly resilient communication interfaces (CAN, Ethernet, Modbus) capable of dynamically handling the idiosyncrasies and proprietary logic of different OEM packs without compromising overall system stability.
  • Must possess the communication skills and technical authority to confidently lead complex software discussions, drive alignment across organizational boundaries, and steer reverse-engineering efforts.

Requirements

  • Technical Mastery: Proven track record in controls and software engineering with a deep, practical understanding of lithium-ion battery architectures, external BMS software, and pack-level integration.
  • Modern Tech Stack: Proficiency in modern software engineering practices and languages (Rust, Python, C/C++).
  • Protocols & Networking: Expertise in automotive and industrial communication networks (CAN, LIN, Automotive Ethernet) and their associated diagnostic toolchains.
  • If you have additional privacy-related questions, please contact us at privacy@redwoodmaterials.com.
  • Proficiency in modern software engineering practices and languages (Rust, Python, C/C++).
  • Stakeholder Engagement & POC Experience: Demonstrated experience acting as a primary software POC with external suppliers, automotive OEMs, or internal cross-functional teams. Must possess the communication skills and technical authority to confidently lead complex software discussions, drive alignment across organizational boundaries, and steer reverse-engineering efforts.
  • Adaptive Problem Solving: Exceptional capability to reverse-engineer, troubleshoot, and adapt complex OEM electro-mechanical software systems for novel applications in circular energy ecosystems.
