Why this role exists
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.
FIRST 90 DAYS
Establish the foundation
- Produce a production architecture and reliability assessment with an agreed priority list.
- Ship at least one important customer-facing capability across the full stack.
- Establish service-level indicators, alerts, incident ownership, and a release checklist for critical surfaces.
- Define the authenticated developer path from account creation through a successful API or MCP request.
- Document the highest-risk security, data-access, and scalability gaps with concrete remediation plans.
6 TO 12 MONTHS
Create durable proof
- A new agency or enterprise evaluator can use the product without founder-led technical setup.
- API and MCP access are authenticated, metered, documented, and supportable.
- Production incidents are observable, assigned, and resolved through a repeatable operating process.
- Research capabilities reach customers through stable product releases.
- Infrastructure and serving costs are measured and controlled.
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.
Helpful, not required
- Maps, geospatial systems, high-volume data products, forecasting, or scientific software.
- Developer platforms, public APIs, MCP servers, usage metering, or enterprise access controls.
- Government, infrastructure, utilities, real estate, climate, or planning software.
- Applied AI systems with rigorous evaluation and non-deterministic failure handling.
This is not a pure site-reliability position, a frontend-only position, or an internal-tools position. You must ship customer product and own the production foundations beneath it.
Compensation and working terms
$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.
New York City is preferred. We will consider exceptional candidates elsewhere in the United States.
