What is a senior software engineer?

A senior software engineer designs, codes, tests, and maintains computer software. While these are your primary responsibilities as a senior software engineer, you may also have supervisory duties. These include overseeing a team of junior software engineers or developers. The senior software engineer title is sometimes used interchangeably with senior developer, and positions for both may share similar job duties and responsibilities. In general, software engineers are distinguished from developers in that software engineers apply engineering principles to software development.

What are the key skills and qualifications needed to thrive as a senior software engineer, and why are they important?

To thrive as a Senior Software Engineer, you need advanced programming skills, deep understanding of software architecture, and several years of experience in software development, often supported by a relevant degree. Familiarity with tools like Git, CI/CD pipelines, cloud platforms, and expertise in technologies such as Java, Python, or JavaScript are typically required. Leadership, problem-solving, and effective communication are crucial soft skills for mentoring teams and collaborating across departments. These skills ensure the delivery of robust, scalable solutions and drive successful project outcomes in complex technical environments.

What are some common challenges senior software engineers face when mentoring junior team members?

Senior Software Engineers often mentor junior colleagues, which can be incredibly rewarding but also presents challenges. Balancing mentorship with project deadlines can be demanding, as it requires strong time management and communication skills. Additionally, adapting explanations to different learning styles and levels of experience can be tricky. However, effective mentorship helps build a stronger team and can lead to enhanced leadership opportunities for the senior engineer.

KAYAK, part of Booking Holdings (NASDAQ: BKNG), is the world’s 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.

Our focus is on building the best travel search engine to make it easier for everyone to experience the world.

We are looking for a strong Senior Java Software Engineer to implement new features and maintain KAYAK’s world-leading platform. We are seeking for people who love working with data - parsing, analyzing, investigating, interpreting, modeling, and extracting knowledge from large volumes of data. Good candidates will have a passion in processing data to help drive better business decisions or to develop new features, in a fast-paced environment where many small and diverse projects are the norm.

This role will be required to work from our Concord, MA office at least 3 days per week.

In this role, you will:

  • Communicate with APIs via REST or SOAP interfaces.

  • Configure enterprise applications for large customers.

  • Develop tools to assist in the debugging of existing products.

  • Build and maintain high-performance integrations with third-party APIs (airlines, hotel and rentalcars providers)

  • Take full ownership of your designs: from initial concept to deployment while maintaining high standards for code quality and performance

  • Participate in code reviews and architectural steering to ensure the K4B project remains modular and reusable as KAYAK expands its enterprise footprint

Please apply if you have:
  • +6-8 years of experience with Java programming

  • Strong understanding of programming fundamentals, data structures, algorithms, and software design

  • Ability to work independently and with a team

  • Good communication skills for sharing ideas clearly with both technical and non-technical colleagues

  • Experience with relational databases like MySQL or Oracle

  • Prior experience in the travel domain is beneficial

  • Experience with B2B systems or identity/HR integrations is beneficial — e.g., SCIM, SAML/OAuth, SSO, user provisioning/deprovisioning, and connecting HRIS/IDP platforms (Workday, Okta, Active Directory) to product services.

  • Experience with the following:

    • Unix shell scripting

    • Spring & Mybatis frameworks

    • DOM and using XPath, JQuery & CSS

    • API development using REST, Web Service, SOAP, etc

    • Machine Learning

Benefits and Perks
  • Work from (almost) anywhere for up to 20 days per year

  • Focus on mental health and well-being:

    • Company-paid therapy sessions through SpringHealth

    • Company-paid subscription to HeadSpace

    • Company-wide week off a year - the whole team fully recharges (and returns without a pile-up of work!)

    • No meeting Fridays

  • Paid parental leave

  • Generous paid vacation + time off for your birthday

  • Paid volunteer time

  • Focus on your career growth:

    • Development Dollars

    • Leadership development

    • Access to thousand of on-demand e-learnings

  • Travel Discounts

  • Employee Resource Groups

  • Competitive retirement and health plans

  • Free lunch 2 days per week

  • Fun quarterly events such as boat trips, arcades, ski trips, Thursday socials, and more
