1d • $185,000 - $195,000 • Remote

About The Position

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. Team Overview 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.

Requirements

• 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.
• 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, quality, and system reliability.

Nice To Haves

• Familiarity with utility grid interconnection and market requirements, particularly in ERCOT.

Responsibilities

• Build and Maintain Validation Frameworks
• 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 Testing and Reporting
• Automate test execution to create reproducible validation workflows and reporting tools
• Design verification metrics that demonstrate control performance, safety, and compliance.
• Define Test Cases and Performance Criteria
• Collaborate with engineering teams, utilities, and external stakeholders to define test cases and performance requirements.
• Validate both steady-state behavior and abnormal operating scenarios.
• Integrate Field Learnings into Validation
• 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 Validation Assets and Traceability
• Maintain a well-structured repository of validation assets, test artifacts, and documentation
• Ensure clear version control, traceability, and repeatability across validation workflows

Benefits

• 100% premium coverage for you and your dependents on medical, dental, and vision
• Unlimited PTO, plus two company-wide breaks (Fourth of July & end of year)
• Up to 12 weeks of fully paid parental leave, plus 6 additional weeks for birth parents; access to family planning and family care support through Carrot and Maven
• Free access to Spring Health, including 5 free therapy and psychiatry sessions, plus a Headspace account for mindfulness and meditation through our physical health vendor, Wellhub+
• $150 monthly food stipend, $150 monthly reimbursement for cell phone and internet, pet insurance allowance, full home office setup, free access to UrbanSitter with $625 in quarterly company-paid credits, ActiveHero, and One Medical
