About ResortPass

ResortPass is an online booking platform for access to resorts and hotels for the pool, spa, fitness, and activities. Locals and travelers can enjoy leisure amenities at amazing hotel properties without needing to book a room. Our Day Guest Program provides the entire system for hotels to benefit from a significant new revenue channel: inventory & pricing management, online booking, revenue data & reporting, marketing, and full guest support. With over 350 hotel partners and growing across top brands such as Hyatt, Marriott, Four Seasons, Hilton, Fairmont, Ritz-Carlton, and many more, we are on the forefront of not only a shift in the hospitality industry but in creating a new category of how people enjoy time with family and friends, as well as those looking for some solo me-time. A fast-growing Silicon Valley venture-backed startup based in sunny Santa Monica, blocks from the beach, we are excited to bring the "daycation" experience worldwide.

About The Role

We’re looking for a senior backend engineer with an infrastructure sense to join our Platform team as a contractor. This is a high-impact role for someone who thrives at the intersection of backend systems and infrastructure—comfortable designing APIs or optimizing SQL queries one day, tuning Docker workflows or CI pipelines the next. Our team is responsible for the architecture, scalability, and resilience of the systems that power all of engineering. You’ll take ownership of critical platform capabilities - security, performance, observability, developer experience - and help evolve our architecture as the company scales. We value engineers who combine technical depth with curiosity, care deeply about quality, and take pride in solving hard problems end to end. If you enjoy building foundational systems that empower product teams and raise the bar for engineering excellence, we’d love to work with you.

What You’ll Do

  • Design and implement scalable backend systems that enhance reliability, performance, and security—working across a polyglot stack (Kotlin, Ruby, Node.js).
  • Improve and maintain platform infrastructure, including CI/CD pipelines, observability, container orchestration, and secure deployment patterns.
  • Partner with engineering teams to provide architectural guidance, close security and reliability gaps, and raise the bar for operational excellence.
  • Take ownership of high-impact, cross-cutting initiatives from exploration through delivery—building solutions that scale and empower the broader engineering org.

What You’ll Bring

  • 7+ years of experience in backend development with Ruby, Kotlin or Node.js
  • Strong technical depth in backend systems and infrastructure.
  • Experience with designing APIs and optimizing SQL queries.
  • Proficiency in tuning Docker workflows and CI pipelines.
  • Ability to take ownership of critical platform capabilities such as security and performance.
  • Curiosity and a deep care for quality in solving complex problems.
  • Pride in building foundational systems that empower product teams and enhance engineering excellence.
