Controls Engineering Jobs in California (NOW HIRING)

The Head of Microgrid Controls is the technical owner of BoxPower’s controls platform and the future leader of BoxPower’s controls engineering team. This role has two interlocking arcs: a hands‑on individual‑contributor phase now, and a player‑coach leadership phase over the next 12-18 months as BoxPower scales the controls function and hires additional engineers under this role’s direction.

In the near term, you will operate primarily as an IC — owning the architecture, software design, and evolution of the controls systems that run every BoxPower microgrid. You will translate scope documents, control narratives, and state machine definitions into working control logic and validated systems. You will define and evolve the software architecture, evaluate and select compute platforms, build simulation and testing environments, and integrate emerging AI-driven development practices into the controls engineering workflow. Your work spans from factory acceptance testing at BoxPower’s facility through on‑site commissioning and startup of utility‑grade microgrid systems.

Over the medium term, you will build and manage a controls engineering team — hiring, mentoring, and developing direct reports as project volume grows. You will set technical direction for the discipline, partner with the VP of Technology on roadmap decisions, and represent the controls function in cross‑functional planning. Project sizes range from 100 kW to 20 MW and include solar PV, BESS, generators, and other distributed energy resources.

You will work closely with the Applications Engineer (who owns broad design and analysis work) and the Senior Field Commissioning Engineer (who owns physical‑plant commissioning), with the Head of Microgrid Controls owning the controls platform and integration end‑to‑end.

BoxPower’s engineering culture integrates AI tools (Copilot, Claude, ChatGPT, and others) throughout our workflow for code, documentation, analysis, and design assistance. As Head of Controls, you will help shape how BoxPower’s engineering org uses AI in production controls work.

• Define and evolve BoxPower’s controls software architecture for scalability, maintainability, and reuse across project types.
• Architect a modular, reusable code base that accelerates deployment across BoxPower’s standard and custom products.
• Evaluate, select, and develop on SEL RTAC/PLC, industrial PCs, embedded PCs, and other compute platforms for controls applications.
• Develop and maintain integration libraries for batteries, solar PV inverters, generator controllers, fuel cells, wind, and emerging DER types.
• Build simulation and testing environments for validating controls logic across diverse interconnection configurations.
• Integrate AI tools and methods into controls software development, testing, and documentation workflows.
• Develop and enhance remote monitoring, control, and diagnostics capabilities for deployed microgrid assets.
• Build tools and workflows that enable remote commissioning support, reducing on‑site time and travel requirements over time.

• Own the design, programming, and configuration of PLC/RTAC-based control systems for microgrid applications.
• Program and configure industrial PCs, HMIs, and SCADA/HMI platforms.
• Develop and implement DER/microgrid control logic including generator paralleling, BESS charge/discharge management, solar PV curtailment, load management, and black start sequences.
• Translate control narratives, state machine documents, and sequences of operation into tested, validated control code.
• Program breaker controls, protective relay settings, and paralleling/synchronization logic.
• Configure communication protocols (Modbus TCP/RTU, DNP3, IEC 61850) and verify addressing, mapping, and data flow between field devices and controllers.

• Confirm all equipment for controls integration: verify specifications, communication maps, protocols, and addressing prior to programming.
• Align scope documents, control documents, and state machine definitions with actual hardware configurations and project requirements.
• Perform factory acceptance testing (FAT) at BoxPower’s facility and support site acceptance testing (SAT) at project locations.
• Integrate BoxPower control systems with third‑party generators, BESS (including Tesla Megapack), solar PV inverters, fuel cells, wind, and other DERs.
• Commission and start up microgrid control systems on‑site, including point‑to‑point verification, functional testing, and performance validation.
• Work safely on electrical control equipment, including energized panels, switchgear, and protection systems.

• Build the controls engineering team over time: scope hiring needs, lead recruiting for direct reports, and onboard new engineers.
• Mentor and develop direct reports and field technicians on controls topics; set performance expectations and conduct regular 1:1s as the team grows.
• Set technical direction for the controls discipline at BoxPower; partner with the VP of Technology on roadmap and resourcing decisions.

• Coordinate with the Applications Engineer on design intent and the Senior Field Commissioning Engineer on commissioning execution.
• Interface with external clients, vendors, and subcontractors on controls integration requirements and commissioning activities.
• Support sales engineering and estimating with controls‑specific technical inputs for proposals and RFPs.

• Create and maintain controls documentation including control system architecture drawings, I/O lists, communication diagrams, and programming documentation.
• Develop and maintain standard controls templates, libraries, and reusable code modules for BoxPower’s product lines.
• Support project engineering with controls‑specific inputs for electrical plansets, cable/conduit schedules, and panel schedules.

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related field; or an equivalent combination of education and professional experience.
• 8+ years of experience in controls engineering, power systems controls, or industrial automation, with significant focus on microgrid, DER, or power generation applications.
• Demonstrated track record as a platform or software architecture owner for industrial controls or microgrid systems — not just project delivery experience.
• Demonstrated experience programming PLCs or automation controllers for power/energy applications. SEL RTAC experience strongly preferred.
• Strong software architecture and development skills with the ability to design modular, reusable code for production controls platforms.
• Working knowledge of communication protocols used in power systems (Modbus TCP/RTU, DNP3, IEC 61850).
• Experience with structured text, codesys, ladder logic, linux, python, javascript, etc.
• Ability to read and interpret single‑line diagrams, three‑line diagrams, relay settings, and protection schemes.
• Experience with generator paralleling controls, breaker controls, and protection relay coordination.
• Hands‑on experience commissioning and troubleshooting electrical control systems in the field.
• Ability to work safely on energized electrical control equipment.
• Demonstrated interest in or experience with people leadership: mentoring junior engineers, leading project teams, or formally managing direct reports.
• Strong written and verbal communication skills with the ability to present complex technical information to engineers, executives, and external stakeholders.
• Willingness to travel 10–25% based on project demands.

• Prior experience formally managing a small engineering team (1‑4 direct reports).
• Combined software and electrical engineering background.
• Experience with SEL RTAC, SEL‑735, SEL‑700G, SEL‑751, or similar SEL devices. Experience with Ignition SCADA platform by Inductive Automation.
