We're hiring an Integrations Engineer to own and scale our third-party

integration surface. The primary focus is OAuth: making token

acquisition, refresh, encryption, multi-account selection, and

revocation rock-solid across every platform we support and shipping

new ones fast.

The role spans our Fastify backend, Next.js frontend, and our fleet of

TypeScript MCP servers.

What You'll Do:

Ship new platform integrations Bing Ads, LinkedIn Ads, Pinterest,Snap, HubSpot, Salesforce, Mailchimp, GA4, Stripe-as-data-source, and whatever customers ask for next.
Own the OAuth layer end-to-end: token acquisition, refresh-on-expiry, revocation handling, scope upgrades, multi-account selection,workspace-scoped isolation.
Harden the existing connectors: reduce token-refresh failures,improve rate-limit handling, fix partner API regressions, tighten webhook reliability.
Build new MCP servers following our existing pattern (dual stdio + HTTP JSON-RPC, tokenRetrieval.ts, prefixed tools).
Scale connection UX: improve the channel-connector flow, error states, reconnect prompts, account-selection UI.
Reduce integration toil: extract a shared OAuth/connector framework so adding a new platform takes days, not weeks.
Observability & monitoring: instrument every connector with Sentry (error tracking, performance traces, release health), structured logs, and dashboards for token-refresh success rate, partner API latency, rate-limit hits, and webhook delivery. Own alerting so connector regressions are caught before customers report them.
Security: AES-256-GCM token encryption at rest, secret rotation,threat-model new connectors before launch.

WHAT WE'RE LOOKING FOR

Hands-on experience building production integrations against realthird-party APIs.
Deep, practical OAuth 2.0 knowledge: auth code flow, PKCE, refresh tokens, scope management, multi-tenant token storage.
Strong TypeScript and Node.js (Fastify v5 + Next.js 16 + native MongoDB driver).
Comfortable with token encryption, secret rotation, and webhook signature verification.
Experience instrumenting production services with Sentry (or equivalent: Datadog, New Relic, Honeycomb) error tracking,tracing, alerting, on-call hygiene.
Pragmatic debugger can read partner API docs, reproduce failures, and ship a fix the same day.

Nice to have

Experience with MCP, JSON-RPC, or other tool-calling frameworks for LLMs. Azure App Service / Azure SQL exposure.
Prior work at an ad-tech, attribution, or marketing-analytics company.
Familiarity with WorkOS or similar enterprise auth providers.
