We were born at X, the innovation lab responsible for breakthrough technologies like Waymo, Verily and Google Brain. To keep pace with humanityu2019s growing energy needs, the world needs a grid that is visible and understandable. We provide that clarity by building advanced, AI-enabled analytical and planning tools that allow the entire energy ecosystem to plan smarter, move faster, and operate more efficientlyu2014ensuring electricity remains reliable and affordable for everyone. This is a global effort. Tapestry is proud to support partners in the U.S., U.K., Chile, New Zealand, Australia and Brazil as they build a cleaner, more resilient energy future. Joining Tapestry allows you to do the best work of your life as part of a multidisciplinary team of experts in AI, energy systems, software engineering and product designu2014all collaborating to reshape energy on a global scale. If you want to tackle problems that matter and build tools with real impact, we would love to meet you. Learn more about our team and our missionhere ( About the role In this role, you will support high-impact software engineering projects focused on improving the performance, scalability, and reliability of Tapestryu2019s grid simulation and analysis platform. The system is used to run large-scale power system studies for external utility partners, requiring complex simulations to scale efficiently across thousands of feeders with low latency and high reliability. Your primary objective will be to prototype and de-risk the technical feasibility of scaling core analysis features. You will work closely with experienced software engineers and applied AI partners to analyze performance bottlenecks, implement improvements, and validate results through benchmarking and testing. This role is ideal for a junior engineer who enjoys debugging, optimization, and understanding how systems behave at scale. This is a full-time, 12 week software engineering intership. How you will make 10X Impact + Analyze the runtime and computational performance of core grid analysis features, such as power flow, feeder screening, and contingency analysis. + Identify performance bottlenecks related to algorithms, parallel computation, or cloud service interactions. + Implement targeted performance improvements and benchmark results before and after changes. + Prototype and evaluate AI/ML-assisted approaches to reduce the combinatorial complexity of large-scale contingency analysis. + Produce clear, data-driven performance reports that document findings, tradeoffs, and outcomes. + Contribute clean, well-documented prototype code that can inform future production implementations. + Collaborate cross-functionally with software engineering and AI teams to assess scalability and feasibility. What you should have: + Currently pursuing a Bacheloru2019s or Masteru2019s degree in Computer Science, Software Engineering, or a related technical field. + A strong foundation in software engineering fundamentals. + Experience with algorithmic analysis, debugging, and performance measurement. + Programming experience in Python or a similar language used in data-intensive systems. + Strong written and verbal communication skills, with the ability to explain technical concepts clearly. + Curiosity, persistence, and a willingness to experiment, iterate, and learn. Itu2019d be great if you also had one or more of these: + Interest or experience in performance engineering, such as runtime analysis, parallel computation, or latency optimization. + Familiarity with cloud-based systems (GCP preferred). + Exposure to AI or machine learning concepts through coursework or academic projects. + Experience working on systems that handle large datasets or complex simulations. + Interest in infrastructure, systems, or sustainability-focused technology. Our values + Take charge : We take initiative and own outcomes that move the mission forward. + Transform with purpose: We build solutions that solve real problems and create meaningful impact. + Be a Tapestry, not a thread : We collaborate across diverse skills and perspectives to achieve more than we can individually. + Always fine-tune : We stay curious, seek feedback, and refine our understanding as we learn. + Stay grounded : We listen openly, value different perspectives, and stay focused on what matters most. What we offer + Competitive salary + Medical, dental, and vision coverage + A culture that supports growth, ownership, and meaningful impact, along with: + Immersion in a world-class research environment at the intersection of AI and climate tech. + Competitive residency stipend and housing relocation support for the duration of the program. + Direct mentorship from industry-leading research scientists and engineers. + Opportunity to work on
