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. 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.

Staff Controls Engineer

We are seeking an experienced Staff Controls Engineer who is passionate about pushing beyond the cutting edge of the industry to design, build, and debug best-in-class controls systems for Redwood’s battery recycling operations. This engineer will play a critical role in designing, commissioning, scaling, and supporting all of Redwood’s recycling facilities working at the intersection of chemical process engineering, industrial automation, and software development.

Responsibilities will include:

Designing and implementing real‑time control software in C++ for embedded and industrial systems
Developing automation tools, diagnostics, and orchestration scripts in Python
Writing, optimizing, and troubleshooting Structured Text (IEC 61131‑3) for PLCs and industrial controllers
Building deterministic control loops, state machines, and safety‑critical routines
Integrating software with sensors, actuators, drives, and industrial communication networks
Debugging complex issues involving timing, concurrency, hardware interfaces, and industrial protocols
Leading system architecture decisions for control platforms and distributed automation systems
Conducting root‑cause analysis for field issues and implementing long‑term fixes
Collaborating with controls, electrical, and product teams to translate requirements into robust software designs
Mentoring engineers in real‑time programming, PLC development, and industrial best practices

Qualifications:

Strong proficiency in modern C++ for real‑time or embedded systems
Solid experience with Python for automation, tooling, or data processing
Hands‑on experience writing Structured Text for PLCs or industrial controllers
Deep understanding of deterministic execution, concurrency, and hardware‑software interaction
Experience with industrial protocols such as Modbus, EtherNet/IP, OPC UA, or PROFINET
Proven ability to lead complex engineering efforts while contributing significant hands‑on code
Strong debugging skills across software, hardware, and network layers
Excellent communication and collaboration skills

Preferred Qualifications:

Experience with motion control, robotics, or process automation
Familiarity with embedded Linux, RTOS environments, or microcontroller development
Knowledge of industrial cybersecurity standards or best practices
Experience with simulation tools, digital twins, or hardware‑in‑the‑loop testing
Background integrating C++ runtimes with PLC or SCADA systems

The position is full-time. Compensation will be commensurate with experience.
