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. 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.
Embedded Software Engineer – Power Electronics
We are at the precipice of a global energy transition. At Redwood Materials, we are moving beyond battery recycling to build the most advanced, circular energy ecosystem on the planet. Our goal is to move the industry away from static, hardware-heavy infrastructure toward agile, software-controlled energy assets. While others build "black box" hardware, we are building software-defined power systems. Our Embedded Software team is responsible for the intelligence that drives our power stages, ensuring our energy storage solutions are safe, efficient, and capable of stabilizing the world's most demanding grids. As an Embedded Software Engineer, you will be the architect of the real-time firmware that drives our power conversion units. You will live at the intersection of silicon and power, writing the low-level code that controls high-speed switching, manages thermal safety, and communicates with the broader site infrastructure. You will be responsible for bringing new products from white-space R&D to global scale, ensuring our code is as resilient as the hardware it controls.
Responsibilities will include:
- Real-Time Control Firmware: Design and implement bare-metal software applications for power electronics, focusing on high-resolution PWM generation, ADC synchronization, and complex timing logic.
- Low-Level Architecture: Develop and optimize drivers for microcontroller peripherals (SPI, CAN, Ethernet) and architect memory-efficient, multi-core processing strategies for real-time targets.
- Hardware-Software Synergy: Collaborate with power electronics controls engineers to translate controls theory into deterministic, high-performance code running on Cortex-R and Cortex-M architectures.
- Modern Build & Test: Maintain robust software build procedures and scripts. You will write highly testable code and integrate it into a modern CI/CD pipeline to ensure every line of code is validated before it hits the lab.
- System Optimization: Profile and optimize code across multi-core environments, ensuring maximum task efficiency and minimal latency in time-critical control loops.
- Product Scaling: Leverage a proven track record to take embedded systems from initial prototype to mass-market production, maintaining high standards for code quality and reliability.
Desired Qualifications:
- Background: A BS or MS in Electrical Engineering, Computer Engineering, or Computer Science, combined with 2+ years of experience in firmware engineering and a proven track record of shipping new products at scale.
- Embedded Mastery: Expert proficiency in Rust or C with deep experience debugging complex embedded systems using oscilloscopes, logic analyzers, and JTAG/SWD debuggers.
- Silicon Expertise: Extensive experience with ARM Cortex-M and Cortex-R architectures, including low-level system architecture, multi-core memory optimization, and bare-metal task management.
- Power Electronics Literacy: A deep understanding of power-specific software requirements, specifically high-speed ADC sampling, high-resolution PWMs, and hardware timers.
- Safety-Critical Development: A safety-centered mindset with experience implementing functional isolation and ensuring freedom from interference (FFI) in complex, multi-core software environments. Familiarity with UL certification standards for energy storage systems is a significant plus.
- Communication Protocols: Practical experience with digital protocols such as I2C, UART, SPI, CAN/CAN-FD, and Ethernet. Familiarity with reverse-engineering CAN protocols or developing custom evaluation tools is a significant plus.
- Infrastructure & Automation: Knowledge of software build systems and the ability to maintain build scripts (e.g., Make, CMake). Experience with test automation and CI/CD is essential.
- Bonus Qualifications: Experience developing bootloaders, implementing secure boot, or profiling code on real-time, multi-core targets.

Align your resume to battery tech systems
Redwood Materials builds software around manufacturing execution, materials tracking, and process automation. Framing your experience around industrial systems, embedded controls, or supply chain platforms signals relevance to their engineering stack before your application reaches a recruiter.
Verify your degree supports specialty occupation
H-1B and E-3 petitions require your role to qualify as a specialty occupation. Software Engineer positions at a manufacturing company often involve domain-specific requirements, so confirm your degree field aligns with the posted job description before accepting an offer.
Target roles that name specific technical domains
Redwood posts Software Engineer openings across distinct areas like data engineering, embedded systems, and manufacturing software. Applying to roles where your technical background directly maps to the listed domain strengthens the specialty occupation case your employer files with USCIS.
Ask about LCA timing before your start date
Your employer must file a certified Labor Condition Application with DOL before submitting your H-1B or E-3 petition. Confirm this is initiated early enough that your start date isn't delayed if DOL certification runs longer than the standard seven business days.
Use Migrate Mate to filter open roles by visa type
Redwood Materials posts Software Engineer roles across multiple visa categories. Use Migrate Mate to filter current openings by the visa type you need, so you're targeting positions where your authorization pathway is already supported by the employer.
Clarify OPT STEM extension eligibility early
Manufacturing companies like Redwood must be enrolled in E-Verify to support a 24-month STEM OPT extension. Confirm enrollment status before your initial 12-month OPT expires, since the extension application must be filed before your current authorization ends.
Frequently Asked Questions
Does Redwood Materials sponsor H-1B visas for Software Engineers?
Yes, Redwood Materials sponsors H-1B visas for Software Engineer roles. Their engineering hiring spans multiple technical domains within battery manufacturing and recycling operations, and the company has an established pattern of supporting international candidates through the H-1B process. If you're currently on OPT or another nonimmigrant status, it's worth confirming visa support directly during the offer stage.
How do I apply for Software Engineer jobs at Redwood Materials?
Applications go through Redwood Materials' careers page, where Software Engineer roles are listed by team and technical focus area. You can also browse current openings filtered by visa type on Migrate Mate, which surfaces roles where sponsorship is already part of the hiring process. Tailor your application to the specific domain the role covers, whether that's manufacturing software, data infrastructure, or embedded systems.
Which visa types does Redwood Materials commonly use for Software Engineers?
Redwood Materials supports several visa categories for Software Engineers, including H-1B, E-3 visa (for Australian citizens), TN visa (for Canadian and Mexican nationals), F-1 OPT and CPT for students, and immigrant visa pathways including EB-2 and EB-3 for longer-term sponsorship. The right visa depends on your nationality, current status, and career stage. Each category has distinct filing requirements and timelines that your employer's immigration counsel will manage.
What qualifications and experience does Redwood Materials expect from Software Engineer candidates?
Redwood Materials typically looks for engineers with backgrounds in areas relevant to their manufacturing operations, including data engineering, software systems for industrial environments, automation, or supply chain platforms. A bachelor's degree or higher in computer science, software engineering, or a closely related field is standard for visa sponsorship eligibility. Roles vary in seniority, so experience requirements depend on the specific team and technical scope of the position.
How do I plan my timeline if I need H-1B sponsorship from Redwood Materials?
The H-1B cap registration window opens in early March each year, with selection happening shortly after. If selected, petitions are filed for an October 1 start date. That means offers need to be in place before March for cap-subject candidates. If you're already in H-1B status with another employer, a transfer can happen at any time without waiting for the next lottery cycle.
