$190k - $210kFull-time
Atrium
Client Overview Our client is a profitable, Series B-funded technology company transforming how consumers access premium hotel amenities and experiences without requiring an overnight stay. The company operates a rapidly growing marketplace connecting consumers with leading hospitality partners through both B2B distribution solutions and a consumer-facing platform. With approximately 30% – 35% year-over-year growth, the business continues to expand its technology offerings, partnerships, and engineering organization. They are looking to add Senior Backend Engineers to their team. The Engineering team values strong computer science fundamentals, technical excellence, sound judgment, and collaborative problem-solving. This is an opportunity to join a growing team where engineers have meaningful ownership, contribute to important architectural decisions, and build scalable technology supporting continued business growth. Salary/Hourly Rate $190k - $210k plus Equity, with some flexibility for exceptional candidates. Position Overview Our client is seeking two Senior Backend Engineers to help develop and scale the company's core booking platform and external API infrastructure. These engineers will build APIs that enable distribution partners and authorized AI agents to price, hold, book, modify, and cancel live hotel inventory. The Senior Backend Engineers will take ownership of backend services, third-party integrations, and technical decisions while developing reliable, scalable systems that support new hospitality experiences and product categories. This is a hands-on individual contributor role for engineers who enjoy writing production code, solving complex technical challenges, and delivering meaningful improvements. Working closely with a Staff Engineer, the Senior Backend Engineers will contribute to foundational architecture while independently driving day-to-day engineering initiatives. The ideal candidate brings strong backend development experience, sound technical judgment, and the ability to learn unfamiliar technologies quickly. There is also an opportunity to grow toward Staff-level responsibilities through demonstrated technical impact. Previous experience with Ruby on Rails, OpenSearch, or the hospitality industry is not required. The hiring team prioritizes strong engineering fundamentals, technical judgment, adaptability, collaboration, and the ability to learn new technologies quickly.
