Senior Full-Stack Product Engineer
Parisi Labs is an AI company building learning systems for complex physical environments. We combine historical and live data with real operational context to help people understand the present, evaluate possible futures, and make better decisions.
Energy is our first proving ground. Ask The Grid is our public product for exploring the systems, markets, and assets that make up the power grid. We are a small technical team working across machine learning, data infrastructure, software, and real-world operations.
About the role
We are hiring a senior full-stack product engineer to take substantial ownership of Ask The Grid and help us build the product experiences that follow from it.
You will work across frontend, backend, data-backed workflows, and AI-assisted product features. The product is already live, so this is not a greenfield mockup role: you will learn from real usage, improve what exists, and ship durable software that makes a complex system understandable and useful.
This role owns the user-facing product experience. It does not own the core machine-learning research agenda or the shared data platform.
What you will own
• Ship end-to-end product improvements across the application, from interface through backend behavior and release.
• Make complex, changing data legible through clear interactions, visualizations, and workflows.
• Improve the ways people explore, save, organize, and act on the information that matters to them.
• Build AI-assisted features that are useful, trustworthy, and clear about their limits.
• Use product evidence to find friction, set priorities with the founders, and measure whether a change worked.
• Raise the bar for performance, reliability, accessibility, and maintainability across the product.
• Help decide which repeated needs should become reusable product capabilities.
You may be a fit if
• You have shipped and maintained production-quality full-stack web software.
• You combine strong engineering judgment with genuine product taste.
• You can move from a user problem to a clear interaction and a reliable implementation without waiting for a detailed specification.
• You are comfortable working with data-heavy applications, interactive visualizations, or other interfaces over complex systems.
• You have built AI-assisted product features where correctness, grounding, and failure behavior matter.
• You use modern development tools aggressively while retaining responsibility for the quality of what ships.
• You communicate clearly, make pragmatic tradeoffs, and know when a request should not become a product feature.
Helpful background
• Senior product engineering or founder-close engineering at a high-ownership startup.
• Experience owning both frontend and backend behavior for a meaningful customer-facing product.
• Experience with maps, charts, time-series interfaces, analytical products, or large changing datasets.
• Experience taking an existing product from promising to dependable, coherent, and widely used.
• Energy experience is welcome but not required; curiosity about consequential physical systems is required.
Location and working style
New York City is strongly preferred. Boston/Cambridge can work for an exceptional candidate with a regular in-person cadence. This is a high-context role that works closely with the founders.
Compensation and benefits
Base salary range: $180,000–$260,000, plus meaningful early-stage equity, medical, and dental benefits. Final compensation depends on level, location, experience, and role scope.
