Senior Front End Software Engineer, Retention

Description

KAYAK, part of Booking Holdings (NASDAQ: BKNG), is a leading travel search engine. With billions of queries across our platforms, we help people find their perfect flight, stay, rental car and vacation package. We’re also transforming business travel with a new corporate travel solution, KAYAK for Business.

As an employee of KAYAK, you will be part of a travel company that operates a portfolio of global metasearch brands including momondo, Cheapflights and HotelsCombined, among others. From start-up to industry leader, innovation is in our DNA and every employee has an opportunity to make their mark. Our focus is on building the best travel search engine to make it easier for everyone to experience the world.

This role is required to work from our Kaunas office at least 3 days per week.

In this role you will:

Design, build, and take end-to-end ownership of complex frontend features - from initial scoping and technical design through deployment, monitoring, and follow-up

Write maintainable, well-tested code and actively participate in code reviews, holding yourself and the team to a high standard of quality and reliability

Lead technical design discussions for your team's domain, analyze tradeoffs, and document decisions clearly so the whole team can build on them

Identify and address technical debt, performance issues, and reliability risks proactively - not just when they become urgent

Mentor and support less-experienced engineers through code review feedback, pair programming, and knowledge-sharing sessions

Collaborate closely with product managers and designers to clarify requirements, surface risks early, and ensure features are built to meet real user and business needs

Participate actively in agile ceremonies - sprint planning, backlog refinement, retrospectives, and demos - contributing to a predictable and healthy team delivery rhythm

Contribute to improving team processes, tooling, and engineering standards, and advocate for technical improvements with clear reasoning and evidence

Use AI-assisted development tools responsibly to improve your own productivity and code quality, and stay current with emerging frontend technologies and approaches

Please apply if you have:

Demonstrated experience independently designing and delivering complex frontend features in a production environment - equivalent experience, transferable skills, or non-traditional career paths are all welcome

Strong proficiency in JavaScript and TypeScript, and solid experience building user interfaces with a modern component-based framework (such as React or similar)

A good understanding of how frontend systems interact with APIs and backend services, and experience debugging and optimizing across that boundary

Experience writing and maintaining automated tests (unit, integration, or end-to-end) and a genuine care for code quality and long-term maintainability

The ability to communicate technical ideas clearly — in design documents, code reviews, and team discussions — and to give and receive feedback constructively

A track record of taking ownership of your work through to completion: surfacing blockers early, following through without prompting, and caring about outcomes rather than just task completion

Fluent English communication skills

Comfort working in an agile team environment with iterative delivery, regular collaboration, and shared accountability for team goals

Comfort working in a hybrid model, with at least three office days per week

This would help you to stand out:

Experience working on advertising technology, user engagement features, or revenue-impacting frontend products

Familiarity with A/B experimentation frameworks or feature flagging systems

Experience mentoring or supporting the growth of other engineers on your team

If you are unsure whether your background is a fit, we encourage you to apply. We consider the full picture of your experience, including non-traditional paths and transferable skills.

Conditions

Base pay: from 3330 EUR up to 6660 EUR gross monthly.
