Automate unit and regression testing for grid applications using scripts and tools such as Selenium. Collaborate with grid engineering, systems support, grid operations, training, and network modeling teams to provide technical support for the grid application suite. Collaborate with project management to ensure successful delivery of enhancements and upgrades. Ensure compliance of the grid application suite with ERCOT architectural standards and employ SDLC processes in all projects. May train, mentor, and oversee other developers. Engage with market participants, ERCOT representatives, and vendors to deliver solutions aligned with ERCOT Electricity market needs. Senior‑Level Responsibilities Develop enterprise‑level applications and integration solutions. Define architecture for cloud‑native adaptation of existing grid applications and implementation of new applications. Drive adoption of containerization and microservices where deemed necessary to meet operational needs. Lead AI/ML strategy and implementation for grid applications and analytics. Oversee all phases of the software development lifecycle, including analysis, design, testing, and integration. Advocate and align business requirements for GMS grid applications and user interfaces to ensure effective, user‑focused solutions. Provide technical training and presentations for product solutions related to grid applications. Advise management on technical strategy and development goals of the GMS Technology Development team. Work closely with project management to establish project delivery plans and ensure successful delivery of initiatives. Guide teams across the organization to ensure high‑quality product delivery. Act as a subject‑matter expert, providing guidance to junior team members and supporting their development through mentoring, training, coaching, and assigning work as needed. Qualifications Required experience: Level3 – minimum 3years of job‑related work experience beyond degree requirements; Senior Level – minimum 5years of job‑related work experience beyond degree requirements.
