Senior Software Engineer, Backend — Booking Platform & APIs

About Resort Pass

Resort Pass is redefining what it means to be a hotel guest. We give people daytime access to pools, beaches, spas, cabanas, and other hotel experiences without an overnight stay.

We work with more than 2,700 hotel partners across 30 countries. We have served more than 7 million guests and generated hundreds of millions of dollars for our hotel partners. Marriott has signed a global agreement with Resort Pass, and Hilton has expanded its partnership with us.

We have proven the demand. Now we are building the booking and distribution platform that can bring hotel experiences to many more guests, categories, and channels.

Most travel platforms are built around overnight rooms. Resort Pass is building the platform for everything else a hotel can offer.

A day pass is sold by capacity. A cabana is reserved as a unit. A massage needs a time slot, provider, or room. Events have tickets. Food and beverage may be a product, an add-on, or part of a bundle. Each category has different rules for pricing, inventory, fulfillment, and cancellation.

We need one clear booking domain that supports these differences without creating a separate system for every category. That same inventory must be available through Resort Pass, hotel systems, distribution partners, and authorized booking agents.

We are hiring a Senior Software Engineer to lead the technical work and be the primary hands-on builder for the Resort Pass API. In your first year, multiple distribution partners and an authorized AI agent should complete real bookings through the same versioned API.

You will evolve a production Rails and Postgres booking system used by millions of guests. The hard work is keeping prices and inventory correct, preventing overselling, surviving retries and partial failures, and reconciling systems when they disagree.

You will own the API’s day-to-day technical roadmap and design decisions. In this hands-on individual contributor role, you will write production code, lead focused designs, guide migrations, and operate what you build. You will partner with our Staff Engineer on foundational domain and architecture choices.

You will be the primary builder, but you will not work alone. Other backend engineers will contribute and build supply, PMS, and POS connectors using the patterns you establish. Product, Partnerships, and hotel operations will work with you from requirements through production launch.

This is one of our highest-impact technical bets. What you build will determine how quickly Resort Pass can enter new booking channels and categories.

This role works from our NYC headquarters four days per week. The base salary range is $190,000–$210,000, plus equity, based on experience.

• Build and launch the external Resort Pass API. Define stable, versioned contracts for live pricing, availability, holds, booking creation, changes, and cancellations.
• Make booking operations safe under real failures. Design idempotency, recovery, webhooks, and reconciliation for retries, timeouts, duplicates, and partial success.
• Evolve the core booking domain. Create clear models and in variants for products, schedules, prices, inventory, holds, carts, and bookings.
• Make the platform extensible. Prove that a new category such as events or food and beverage can use the shared booking model instead of requiring a separate system.
• Own the architecture for supply, PMS, and POS integrations. Create reusable connector patterns so other engineers can add partners without reinventing failure handling and reconciliation.
• Define the data contracts that keep inventory discoverable through Open Search. Search is supporting technology for this role, not its primary ownership area.
• Operate what you build. Set reliability and latency targets, and add the tests, metrics, dashboards, alerts, tracing, and runbooks needed for a critical booking path.
• Turn partner needs into durable platform capabilities, explain tradeoffs clearly, and raise the engineering bar through practical reviews and mentoring.

We move quickly by building quality from the start. A change is done when it is tested, deployed, observable, and safe to roll back. We use AI tools aggressively, but engineers remain accountable for architecture, correctness, and production outcomes.
