We give people daytime access to pools, beaches, spas, cabanas, and other hotel experiences without an overnight stay.\nWe 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 ResortPass, and Hilton has expanded its partnership with us.\nWe 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.\nWhy this role matters\nMost travel platforms are built around overnight rooms. ResortPass is building the platform for everything else a hotel can offer.\nA 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.\nWe need one clear booking domain that supports these differences without creating a separate system for every category. That same inventory must be available through ResortPass, hotel systems, distribution partners, and authorized booking agents.\nWe are hiring a Senior Software Engineer to lead the technical work and be the primary hands-on builder for the ResortPass API. In your first year, multiple distribution partners and an authorized AI agent should complete real bookings through the same versioned API.\nYou 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.\nYour ownership and team\nYou 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.\nYou 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.\nThis is one of our highest-impact technical bets. What you build will determine how quickly ResortPass can enter new booking channels and categories.\nThis role works from our NYC headquarters four days per week. The base salary range is $190,000-$210,000, plus equity, based on experience.\nWhat you’ll do\nBuild and launch the external ResortPass API. Define stable, versioned contracts for live pricing, availability, holds, booking creation, changes, and cancellations.\nMake booking operations safe under real failures. Design idempotency, recovery, webhooks, and reconciliation for retries, timeouts, duplicates, and partial success.\nEvolve the core booking domain. Create clear models and invariants for products, schedules, prices, inventory, holds, carts, and bookings.\nMake 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.\nOwn the architecture for supply, PMS, and POS integrations. Create reusable connector patterns so other engineers can add partners without reinventing failure handling and reconciliation.\nDefine the data contracts that keep inventory discoverable through OpenSearch. Search is supporting technology for this role, not its primary ownership area.\nOperate what you build. Set reliability and latency targets, and add the tests, metrics, dashboards, alerts, tracing, and runbooks needed for a critical booking path.\nTurn partner needs into durable platform capabilities, explain tradeoffs clearly, and raise the engineering bar through practical reviews and mentoring.\nHow we ship\nWe 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.\nExploreengineering at ResortPass, includingwhy we work and what we are building next.\nTech stack\nBackend: Ruby on Rails, Node.js\nData: Postgres, MongoDB\nSearch: OpenSearch\nAPIs and integrations: REST, OpenAPI, webhooks\nInfrastructure and observability: AWS, Datadog\nTesting: RSpec, Playwright\nWho you are\nWe encourage candidates to apply even if they do not match every line below.\nYou have 6+ years of software engineering experience, or a track record of equivalent impact.\nYou have designed transactional systems, built external APIs or integration platforms, and safely evolved data models in production.\nYou understand relational modeling, concurrency, consistency, asynchronous workflows, and distributed failures.\nYou turn complex business rules into clear boundaries, lifecycle states, contracts, and invariants.\nYou can lead an important system as its primary builder while collaborating on foundational decisions.\nYou care about correctness, testing, observability, and safe rollouts.\nYou communicate directly, listen well, and improve the work of engineers around you.\nRuby on Rails experience is useful, but not required. Experience with marketplaces, reservations, inventory-constrained commerce, public APIs, or third-party booking systems is also helpful. We care most about your backend judgment, track record, and ability to learn.\nWhat success looks like in 6-12 months\nMultiple distribution partners and an authorized AI agent complete real bookings through one reusable API.\nThe full booking lifecycle meets agreed targets for correctness, success rate, latency, overselling, recovery, and reconciliation.\nReusable contracts and connector patterns materially reduce the work required to onboard the next partner.\nThe shared booking model supports at least one new category without a separate booking system.\nAs the API becomes a company-wide platform, this role can grow toward Staff through demonstrated impact across the booking domain, integrations, and distribution.\nBenefits\nHealth, dental, and vision coverage, with ResortPass contributing to monthly premiums\nStock options\n401(k) plan\nUnlimited paid time off\nPaid parental leave\nAnnual ResortPass credit for pools, beaches, spas, and other experiences","description_format":"text","description_chars":6573,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Parental leave","Stock options"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Hotels & Resorts","Hobbies & Leisure"],"lifecycle":[{"event":"open","at":"2026-09-08T13:47:56Z"}],"visa":[],"liveness":{"score":18,"band":"cold","label":"Long shot","p_open":1,"p_active":0.514,"p_room":0.36,"age_days":69,"expected_fill_days":36,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-20T05:45:00Z"},"pay":{"stated_usd_annual":210000,"is_top_pay":true},"html_url":"https://alion.io/job/resortpass-senior-software-engineer-backend-booking-platform-apis","json_url":"https://alion.io/job/resortpass-senior-software-engineer-backend-booking-platform-apis.json","meta":{"generated_at":"2026-10-20T22:01:40Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":25722,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":450012},"rest":"https://alion.io/mcp/rest/get_company?id=450012"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fresortpass-senior-software-engineer-backend-booking-platform-apis"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fresortpass-senior-software-engineer-backend-booking-platform-apis"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fresortpass-senior-software-engineer-backend-booking-platform-apis"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/resortpass-senior-software-engineer-backend-booking-platform-apis\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fresortpass-senior-software-engineer-backend-booking-platform-apis"}]}
