Job description

Make our product dependable enough that public agencies, infrastructure firms, developers, analysts, and AI systems can use it without founder supervision of every release, integration, or production incident.

We already operate a public web product, interactive map, forecasting services, REST API, MCP server, and a large public-record data surface. We need a senior product engineer to turn those components into one secure, reliable, understandable customer product while increasing release speed.

What you will own

• Build customer-facing capabilities across the web application, interactive map, API, and MCP server.
• Own authenticated accounts, permissions, usage metering, access controls, and developer activation.
• Turn research and model outputs into useful scenario, forecast, comparison, export, and collaboration features.
• Own production reliability, observability, incident response, deployment safety, and performance.
• Establish security and compliance foundations for government and enterprise evaluations.
• Improve application and data-service architecture across TypeScript, React, Next.js, PostgreSQL, Supabase, Cloudflare, and geospatial services.
• Build internal tools that make model, data, and product releases safer and easier to verify.
• Work directly with early users and translate their problems into product decisions.
• Write clear technical plans, architecture decisions, operating playbooks, and post-incident reviews.
• Help establish engineering standards and participate in later engineering hiring.

What we are looking for

• Six or more years building production software, including meaningful backend or platform ownership.
• Ownership of a product capability from user discovery through deployment and iteration.
• Strong TypeScript or comparable backend engineering ability and experience with React-based products.
• Experience with PostgreSQL, cloud infrastructure, observability, CI/CD, security, and incident response.
• Sound architecture judgment under early-stage constraints.
• Clear written communication and experience working directly with founders or customers.

Compensation

$285,000 target base salary, 5% target variable compensation, and a 1.25% target equity grant. Final terms depend on experience, location, and the approved offer package.
