Marlborough, MA is a beautiful small city in central Massachusetts, surrounded by quaint Massachusetts towns and within a day-trip distance of the Berkshires, White Mountains, and Cape Cod. For those who prefer a more urban lifestyle, we are located directly off I-495 within easy commuting distance of Boston and Cambridge (30-40 minutes), Worcester (25 minutes), Nashua, NH (45 minutes) and Providence, RI (50 minutes).

A Software & Controls Engineering Leader is needed to lead the development of a nextgeneration Battery Management System (BMS) and Energy Management System (EMS) for a new form of gridscale energy storage. This role blends hands-on engineering with technical leadership, guiding a small, multidisciplinary development team responsible for both software and controls architecture.
The ideal candidate is equally comfortable designing PLC logic, building CI/CD pipelines, architecture of external control software, and communicating complex technical concepts in a clear, accessible way. This position is central to shaping the control strategy, deployment, and longterm maintainability of the system.

• Lead the design and implementation of the systemlevel BMS and associated control software.
• Serve as both leader and handson technical contributor within a small engineering team.
• Define control strategies, communication architectures, and deployment models for a distributed array of PLCs.
• Translate complex engineering concepts into simplified explanations for internal and external stakeholders.
• Manage a Kanbanbased development workflow, ensuring clear prioritization and predictable delivery.

• Select PLC, I/O, and industrial networking hardware appropriate for gridconnected energy systems.
• Develop core PLC logic using Structured Text, Python, C++ and Ladder Logic.
• Integrate industrial protocols such as Modbus, IEC 61850, or DNP3.
• Support system simulation, hardwareintheloop testing, and labbased development.
• Develop external supervisory control software to manage fleets of PLCs.
• Build and maintain CI/CD pipelines using GitLab.
• Implement containerized services using Docker and manage virtualized environments (VMs).
• Design and maintain databases for sensor and telemetry data.

• Mentor engineers, review code, and enforce high standards for reliability and maintainability.
• Collaborate crossfunctionally with hardware, power systems, and product teams.

• Strong proficiency in Python and C/C++.
• Experience with multithreaded application development.
• Handson PLC programming using Structured Text or Ladder Logic.
• Industrial communication protocols: Modbus, IEC 61850, or DNP3 (any one required; more is a plus).
• Experience with Git, GitLab CI/CD, and modern build pipelines.
• Familiarity with Docker, VMs, and containerized deployment strategies.
• Experience collecting and storing sensor/telemetry data in databases.
• Knowledge of message frameworks like AMQP or ZeroMQ, MQTT and OPCUA.
• Deep understanding of server, router, and network architectures.

• Exposure to DCside and/or ACside power systems equipment.
• Experience with grid interfaces, gridconnected devices, or utilityscale systems is a strong plus.
• Experience interacting with electricity utilities in the deployment of 3rd-party add-ons for substation is a strong plus.

• Bachelor's Degree in Engineering preferably in Software and Controls
• Prior work on energy storage systems, microgrids, or utilityscale controls.
• Experience with simulation frameworks or hardwareintheloop environments.
• Background in safetycritical or highreliability industrial systems.
