Role
Who you are
- Strong, proven programming skills in Java, with the ability to independently design, implement, and own complex backend features end to end
- Solid experience with APIs and SQL — including designing and consuming RESTful APIs and working with relational databases such as MySQL or similar systems
- 5+ years of professional software engineering experience, with a track record of delivering high-quality, production-grade backend systems in a fast-paced environment
- Experience leading the design and delivery of complex technical solutions, including making architectural tradeoffs and owning features through deployment and ongoing operations
- Experience collaborating cross-functionally with product managers, marketing partners, designers, and globally distributed engineering teams to ship impactful features
- A collaborative mindset and openness to learning and sharing ideas, including a willingness to mentor others through code reviews and knowledge sharing
- Ability to manage multiple priorities and adapt to changing needs without requiring close direction, balancing sprint commitments with longer-term technical work
- Education in Computer Science or a related field, or equivalent practical experience and transferable skills
- Experience with JavaScript, React, HTML, and CSS is a plus, especially when debugging or collaborating on full-stack solutions with partner teams

- Explore and apply emerging technologies — including AI-assisted tooling and automation — to improve developer productivity, personalization, and platform capabilities
Our take
KAYAK is a travel agency and metasearch engine owned and operated by Booking Holdings. KAYAK processes over 6 billion queries across its platforms each year for travel information - as one of the world’s leading travel search engines, KAYAK searches other sites to show travellers the information they need to find the right flights, hotels, rental cars and vacation packages. It offers a variety of tools and features such as KAYAK trips, explore, and price forecast.
There’s been speculation over the years about online travel companies getting into the hotel business, and KAYAK is no exception. The company is expanding its hospitality offerings beyond its traditional hotel referral and booking services, but despite speculation through the 2020s, has stopped short of opening hotels under its own brand, preferring to partner with preexisting companies on their hotel tech.
Since being acquired by Booking Holdings, the global leader in online travel, in 2013, KAYAK has continued to expand and innovate, enhancing the travel experience for users all around the world. And now KAYAK manages a portfolio of metasearch brands including SWOODOO, checkfelix, momondo, Cheapflights, Mundi and HotelsCombined. With the aim to make it easier for everyone to experience the world - it now operates sites in more than 70 countries and territories.
