Job description

Start your very own journey – with HolidayCheck!

At HolidayCheck, everything revolves around making vacations better – together. We're not only enabling the best time of the year for our travelers, but also creating an inspiring work atmosphere for our HolidayCheckers in our modern office in Poznan.

We live our company values every day: as #TeamHolidayCheck, we build trust, take ownership, and love what we do – all for the perfect holiday experience!

We are looking for a passionate software engineer with hands-on experience building resilient microservice architectures. You will be part of our team in Poznan to implement scalable partner integrations into our internal travel tech platform.

Your Tasks

  • You develop, test, and deploy microservices that integrate external APIs.
  • You ensure scalability, high availability, and fault tolerance in a distributed system.
  • You write clean, maintainable code, following community best practices.
  • You participate in code reviews, giving and receiving meaningful feedback.
  • You collaborate closely with peers in a small agile team.

What you bring

  • At least 3 years of professional experience developing software with Java.
  • Experience with SQL and NoSQL databases like PostgreSQL or MongoDB.
  • Proven track record building microservices, preferably with modern Java frameworks like Micronaut or Quarkus.
  • Practical experience working with distributed systems, such as microservice architectures and message brokers (e.g., Kafka, RabbitMQ).
  • Strong commitment to clean code principles, like Object-Oriented Design, Unit and Integration Testing.
  • Comfortable in agile environments with high degrees of autonomy and an interest to learn.
  • Collaborative mindset: able to give and receive constructive feedback

Nice-to-have Skills:
  • Familiarity with Docker & Kubernetes for containerization and orchestration.
  • Knowledge of CI / CD pipelines (Jenkins, GitHub Actions).
  • Experience with other JVM languages like Scala.
  • Experience with observability tools like Prometheus, Grafana or OpenTelemetry.
  • Experience in performance optimizations of code.

Our “All Inclusive Package” for you

Workation & Flexibility
  • 20 days of workation within the EU – work where others go on vacation
  • 60/40 hybrid model: two office days for collaboration & team spirit, three days remote
  • Flexible working hours – early bird or night owl? We’ve got you covered!
Development & Culture
  • Extensive internal & external training opportunities
  • Diverse corporate culture with over 30 nationalities
  • From newbie to champion: We set up structured onboarding for a smooth start
Perks & Appreciation
  • Anniversary perks in the form of extra vacation days or travel subsidies

  • Public transportation subsidy: You can benefit from a subsidy for ZTM tickets in Poznań
Work-Life-Balance & Wellbeing
  • 28 days of paid holidays for everyone annually
  • Childcare subsidy (up to 800 PLN/month per child)
  • The opportunity to join private health care, which is subsidized by the company and covers you, your partner and children
  • Very preferential terms for life and accident insurance
  • 100% of sick pay (instead of the statutory 80%)
