Principal Engineer (Tapestry)

About Tapestry

Tapestry is Alphabet’s moonshot for the electric grid, working at the frontier where energy’s complexity meets AI’s potential. We were born at X, the innovation lab responsible for breakthrough technologies like Waymo, Verily and Google Brain.

To keep pace with humanity’s 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 efficiently—ensuring 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 design—all 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 mission here.

About The Role

We are looking for a Principal Engineer to lead the architecture of key components within Tapestry’s core platform. You will help shape the technical roadmap for our grid intelligence layer, ensuring our AI-driven simulations and data systems can scale to manage the world's most complex power grids.

How You’ll Make 10x Impact

• Architect Core Systems: Lead the technical design of Tapestry’s intelligence platform by connecting high-fidelity power system modeling with large-scale AI infrastructure.
• Build Scalable Infrastructure: Design distributed systems that process massive, high-velocity geospatial and electrical data with high reliability and performance.
• Drive Technical Milestones: Partner with AI Researchers, Power Systems Engineers, and Product Leads to translate moonshot goals into executable technical plans.
• Foster Engineering Excellence: Promote a product-driven culture where architectural decisions deliver direct value to grid operators and utilities.
• Improve Technical Standards: Refine processes for code quality, system design, and testing across the engineering organization.
• Strategy and Scalability: Identify technical gaps and navigate trade-offs between speed-to-market and long-term system growth.
• Mentor and Multiply: Act as a technical leader by mentoring senior engineers and collaborating with other Tech Leads to foster high-velocity execution.
  
  

What You Should Have

• Have 15 years of experience in software engineering, with a significant track record of leading large-scale, complex technical projects from conception to launch.
• Think from first principles to solve high-stakes problems where there is no existing playbook, particularly at the intersection of software and physical systems.
• Hold an exceptionally high bar for craftsmanship, taking pride in building robust, elegant, and maintainable systems.
• Navigate technical ambiguity with calm, structured reasoning and a passion for radical simplification of complex problems.
• Communicate with clarity and purpose, effectively translating deep technical trade-offs for both executive leadership and cross-functional partners.
• Enjoy collaborating with a diverse group of experts (from ML researchers to power grid veterans) to achieve a massive shared mission.
• Feel motivated by real-world impact and the opportunity to build the foundational technology for a carbon-free energy future.
  
  

It’d Be Great If You Had These

• Experience working at the intersection of software and physical systems (e.g., energy, robotics, or hardware integration).
• Experience with large-scale AI infrastructure or geospatial data processing.
• Track record of delivering scalable solutions in startup or high-growth environments.
• Ability to navigate technical ambiguity with structured reasoning and radical simplification
  
  

Our values

• Take charge: We take initiative and own outcomes that move the mission forward.
• Purpose in everything: We build solutions that solve real problems and create meaningful impact.
• Stronger together: 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.
