Job summary

Tavily in New York City is seeking a Senior Full Stack Engineer to build how developers and AI agents access our agentic web infrastructure. This role is hybrid with the NYC team, based in our New York office.

Our APIs power millions of developers and AI agents; you’ll own the main API gateway, the customer platform (keys, usage, teams), identity and enterprise SSO, and the public interfaces to our product: the SDKs, CLI, MCP servers and other tools.

• 5+ years of full-stack engineering on customer-facing products or high-throughput APIs.
• Strong backend, ideally Python; Go/C++ with Python also fits.
• Experience with latency-sensitive APIs: caching, async, queues, rate limiting.
• Shipped production UI with React/Next.js/TanStack, TypeScript.
• Built data-heavy interfaces with tables, charts, filters.
• Joined a complex codebase and on-call experience.
• Strong product and design sense for APIs and UI.
• Take work from design to production and explain trade-offs.

Responsibilities

• Design and ship features end to end, from the interface to the services and data behind it
• Build and improve the API gateway: high traffic, low latency, reliable
• Turn usage, billing and team data into fast, usable interfaces: tables, charts, filters and forms
• Shape the self-serve journey from signup through activation
• Build and operate identity and team access in production: OAuth and OIDC, role-based access, SAML SSO and SCIM, on providers such as Auth0, Okta, WorkOS or Clerk
• Control who gets which features, with feature flags for staged rollouts and entitlements after rollout
• Improve the public interfaces developers and agents use: the SDKs, CLI, MCP servers and docs
