About Wander
Wander is building the infrastructure to experience the world. WanderOS is our "Shopify for hospitality": the platform property managers use to run direct-booking sites, sync inventory from their PMS, take payments, and manage guests. It is the fastest-growing part of Wander and the system every other product now runs on.

The role
You will own backend services at the core of WanderOS: PMS integrations and sync, availability and pricing pipelines, booking and payments, and the APIs that power host dashboards and every direct-booking site we deploy. This is high-leverage, high-ownership work. Bugs here mean a host loses a booking, so correctness and observability matter as much as speed.

What you'll do

• Design and ship TypeScript services and APIs that handle bookings, quotes, availability, payouts, and site provisioning
• Build and harden PMS integrations (Guesty, Hostaway, OwnerRez, Lodgify, Streamline, Track, Escapia, and more), including webhooks, rate-limit handling, and reconciliation
• Scale ingestion and sync pipelines that process hundreds of thousands of availability records per hour without drift or double-bookings
• Model data in Postgres with Prisma; use Redis, Kafka, and Temporal for queues, caching, and durable workflows
• Own reliability end to end: alerting, tracing, runbooks, and on-call for the services you ship
• Work directly with hosts, ops, and sales to turn real customer pain into shipped fixes, often the same week
• Use AI tooling aggressively in your workflow, and write code and tests that hold up when a large share of the codebase is AI-assisted

What we're looking for

• 4+ years building production backend systems, with deep Node.js and TypeScript experience
• Strong relational data modeling and SQL (Postgres preferred), plus ORM experience such as Prisma
• Experience with third-party API integrations at scale: pagination, rate limits, retries, idempotency, eventual consistency
• Comfort with async/event-driven architecture (queues, streams, workflow engines)
• A product mindset. You care about the host and guest outcome, not just the ticket
• Thrives async and remote, with written communication to match. We do not do meetings

Why Wander
