Software Engineer, Microgrid Controls Validation Engineer

Location & Team Gatherings

Intersect has been a fully flexible workplace since its founding in 2016. We’ve been very intentional about the way we do things. We are not work‑from‑home, hybrid, or in‑office – we are any and all of those options! Deepening social connections and offering shared experiences is a cornerstone of the way we work. We connect as a team at our Team Week experiences four times a year and at our recently established Hub locations – SF Bay Area, NYC Metro Area, NY;
Denver, CO;
Houston, TX;
Calgary, AB; and Toronto, ON.

We are currently looking for candidates located within 60 miles of any of the listed hubs to foster more in‑person connections while maintaining our flexible remote culture.

As part of Intersect’s Microgrid Engineering team, you’ll define and implement the validation framework that ensures microgrid control software performs safely and reliably before it reaches the field. This role focuses on building simulation environments, validation tools, and Hardware‑in‑the‑Loop (HIL) testing that verify controls code across real‑world operating conditions. Working closely with controls engineers, power systems engineers, utilities, and external partners, you’ll help ensure microgrid systems meet performance, compliance, and reliability expectations at scale.

This team plays a critical role in advancing Intersect’s mission to accelerate the clean energy transition, designing and operating systems that deliver reliable power at massive scale. The Microgrid Engineering team works across software, hardware, operations, and external stakeholders to validate complex systems under realistic conditions, ensuring safety, performance, and long‑term operability. Joining this team offers hands‑on exposure to advanced validation techniques and large‑scale energy systems while contributing to work that has real‑world impact.

• Develop software validation tools and simulation frameworks that exercise control algorithms across a full range of operating conditions, including failure modes, communication delays, and equipment faults
• Define requirements and approaches for using real‑time simulators for Software‑in‑the‑Loop (SIL) and Hardware‑in‑the‑Loop (HIL) testing

• Automate test execution to create reproducible validation workflows and reporting tools
• Design verification metrics that demonstrate control performance, safety, and compliance.

• Collaborate with engineering teams, utilities, and external stakeholders to define test cases and performance requirements.
• Validate both steady‑state behavior and abnormal operating scenarios.

• Support analysis of field operating data to refine simulation models and identify edge cases
• Integrate field learnings back into regression test suites to continuously improve validation coverage

• Maintain a well‑structured repository of validation assets, test artifacts, and documentation
• Ensure clear version control, traceability, and repeatability across validation workflows

• B.S. or M.S. in Electrical Engineering, Software Engineering, Computer Engineering, or a related field.
• 3–7+ years of experience in real‑time system validation, embedded software testing, or SIL/HIL simulation.
• Ability to design automated test pipelines and verification metrics for real‑time or embedded systems.
• Experience with simulation tools such as Simulink or Modelica and real‑time simulators, including SIL, HIL, or comparable validation methods.
• Proficiency in industrial control and embedded languages such as C++, IEC 61131‑3 Structured Text, SEL RTAC logic, CODESYS, Lua, Rust, or
  
  C.
• Experience with modern development practices including version control and automated validation workflows.
• Familiarity with utility grid interconnection and market requirements, particularly in ERCOT.
• A collaborative work style and the ability to work effectively with cross‑functional technical teams.
• Strong attention to detail and a mindset focused on safety,…
