## Job description

## About the Company

We are a stealth-mode battery startup developing cutting-edge battery technology. Our mission is to revolutionize battery technology to accelerate the global transition to clean energy. By leveraging innovative materials, advanced manufacturing techniques, and next-generation energy storage architectures, we are building the future of sustainable energy.

Can’t find the company name? It’s not you, it’s us! We’re really excited about the potential of our technology, product, and mission, and have chosen to remain in stealth mode. If the job description piques your interest, please apply. If your skillset is aligned with what we’re looking for, the team will reach out to schedule your interview and tell you a bit more about us (e.g. who we are).

## Role

We are seeking a skilled Senior OT Software Engineer to join our Operational Technology team to help build a custom industrial platform (built on Ignition/Perspective + PostgreSQL) that connects our manufacturing, R&D, and test equipment into a unified digital backbone as we scale from pilot to full production. We're looking for a Senior OT Software Engineer to be a hands-on builder — writing custom Perspective applications, integrating plant-floor and lab equipment, and helping stand up the data pipelines that turn battery test data into decisions.

## Responsibilities

- Design, build, and maintain custom Perspective applications and modules within custom MES/MOM
- Develop scripting (Python/Jython) for Ignition Gateway, tag logic, and UDTs
- Architect PostgreSQL schemas and queries supporting MES/MOM workflows
- Evaluate and integrate complementary platforms (HighByte Intelligence Hub, Coreflux MQTT broker) into the data architecture
- Connect process equipment and battery test equipment via OPC-UA, MQTT, and other industrial protocols
- Build and maintain tag structures, UDTs, and device drivers for new equipment coming online at FR01 and future sites
- Partner with process/manufacturing engineers to scope what data needs to flow and why
- Design and maintain pipelines moving battery test data from equipment into structured storage for analysis
- Collaborate with R&D/data science on data models supporting battery performance analytics
- Ensure data quality, lineage, and accessibility across the pipeline
- Travel regularly between sites to commission systems and support equipment bring-up
- Document architecture and mentor future team members as the OT/MES function grows

## Qualifications

- Strong software engineering fundamentals: has built and shipped production software, not just scripts — comfortable with version control, testing, structured application design
- Strong SQL and relational database design (PostgreSQL preferred)
- Demonstrated ability to learn new platforms quickly and independently in an ambiguous, early-stage environment
- Comfortable working hands-on with physical equipment and industrial data (even if your prior exposure was in a lab/process setting rather than a plant floor)
- 3+ years building industrial software solutions, with substantial hands-on Ignition/Perspective experience (or comparable SCADA/MES platform with strong willingness/ability to ramp on Ignition quickly)

## Preferred Qualifications

- Experience with HighByte Intelligence Hub, Coreflux/Solace, or similar edge/data infrastructure tools
- Background in battery, chemical process, or manufacturing environments
- Data engineering experience (pipeline design, ETL, data modeling)
- Experience with industrial protocols (OPC-UA, MQTT, or similar)
- Advanced degree in engineering or related technical field
- Experience scaling systems from pilot to production manufacturing

Why Join Us?

- Innovative Technology: Work on cutting-edge energy storage solutions that power the future.
- Career Growth: Opportunities to work on high-impact projects and advance in a growing industry.
- Competitive Benefits: Comprehensive health, wellness, and professional development programs.
- Mission-Driven Culture: Be part of a team that is shaping the future of sustainable energy through innovation and excellence.
