Senior Full-Stack Product Engineer

About Parisi Labs

Parisi Labs is an AI research and product company building systems that understand how the physical world changes over time. We combine live data, forecasting, and interactive software so people can see what is happening, reason about what comes next, and make better decisions.

Energy is our first proving ground. Ask The Grid is our live product for exploring the power system across markets, generation, demand, weather, and outages. It gives us a real environment in which to test models, ship useful tools, and learn from real users.

We are a small team working across research, data, and product engineering. Everyone is expected to move from an ambiguous problem to a working system and to care whether the result is useful, reliable, and faithful to the underlying world.

About the role

Ask The Grid is already a substantial live product. We are looking for a senior product engineer to take technical ownership of it and keep making it faster, clearer, more reliable, and more useful.

You will work across React and TypeScript, maps and time-series interfaces, APIs, accounts, data-intensive workflows, reliability, and AI-assisted product experiences. This is a product engineering role for someone who likes owning the whole outcome, not an ML research role.

What you will own

• The public surfaces: maps, radar, assets, network views, and how they work together as one dependable product.
• The path from visitor to operator: accounts and organizations, saving and claiming assets, portfolios, private-data connection, permissions, alerts, and reports.
• Product architecture, APIs, performance, observability, reliability, accessibility, and the ordinary systems that make ambitious software dependable.
• The interaction quality of the agent inside the product: how context is selected, how sources are shown, and what happens when the system should refuse.
• The judgment call about what becomes reusable software, what remains an operator-specific workflow, and what should not be built.

You will work across product, data, model, agent, and decision-system boundaries without replacing the engineers and researchers who own those systems. Your job is to make their capabilities cohere as software a user can understand and trust.

First 90 days

• In your first month, you will ship to production and map the product architecture and the places real sessions stall.
• By day 60, you will ship one end-to-end improvement that measurably improves exploration, account creation, or operator workflow completion.
• By day 90, you will own the product surface and deliver a practical technical plan for the next reusable product capability.

You may be a fit if

• You write production-quality software and have strong product taste.
• You can inherit a large existing application, understand it quickly, and improve it without reaching for a rewrite.
• You care about architecture, tests, observability, performance, accessibility, and the small interaction details users feel.
• You use AI tools aggressively without giving up correctness or clarity.
• You can sit with a battery operator or grid planner and come back with working software, not only a specification.
• You are comfortable saying no to work that will not generalize.

Helpful background

• Senior product engineering, full-stack engineering, or founder-close software work on a substantial live application.
• TypeScript and React in production; strong API and database judgment; comfort in Python where the data lives.
• Maps, charts, time-series visualization, or interfaces over large live datasets.
• Authentication, organizations, permissions, billing, reliability, and production operations.
• Experience integrating LLMs or agents is useful but not required.
• Startup or high-ownership experience is strongly preferred. Energy experience is welcome and not required.

Location and working style
