Senior Java Engineer

About TPConnects

TPConnects is a leading travel technology company with a rapidly growing engineering hub in Warsaw. We build software powering modern airline retailing. Every month, our platforms process millions ticket purchases, connect airlines, and power digital retailing for airline providers.

We’re a product company. We build, own and continuously improve our platform, giving engineers the opportunity to influence architecture, shape technical decisions and solve meaningful engineering challenges at global scale. Our team includes colleagues from dozens of nationalities, making English our everyday language.

About the Role

We’re looking for a Senior Software Engineer to help develop and evolve our cloud-native backend platform. You’ll work on building new capabilities while improving the scalability, performance and reliability of existing services.This role is ideal for engineers who enjoy solving complex technical problems, taking ownership and collaborating with Product Managers, Architects and fellow Engineers to design solutions — not just implement requirements.

Our backend stack includes Java, Spring Boot, AWS, MySQL, DynamoDB and microservices, and we’re continuously evolving our platform as our products and customer base grow.

AI-enhanced development

We use Claude AI coding assistants as part of our everyday engineering workflow to increase productivity and reduce repetitive work. Our engineers use AI to explore technical solutions, accelerate implementation, debug complex issues, generate and improve tests, create documentation and support code reviews. We believe AI helps engineers focus on solving meaningful technical problems—not repetitive tasks.

While AI helps us move faster, great software is still built by great engineers. Engineering judgement, critical thinking and ownership remain at the core of everything we build.

• A product company solving engineering challenges in one of the world’s most complex industries - global travel technology.
• The opportunity to influence architecture, technical decisions and product evolution.
• A chance to help shape our growing engineering hub in Warsaw.
