Are you ready to launch your software engineering career on a project that powers some of the world’s most critical infrastructure? We’re looking for a Junior Java Developer to join a passionate, international team building systems essential to the operation of large-scale Data Centers — from constructing new facilities and designing racks, to hardware demand planning, logistics, and ongoing maintenance.

Our client is a global technology leader operating at a massive scale, where reliability, performance, and innovation are at the heart of everything they do. You’ll be joining a team of world-class engineers and architects to build a scalable, high-performance platform that empowers external customers to create the next generation of applications and solutions.

This is a fantastic opportunity to grow as an engineer in a modern, self-governing team culture that values transparency, autonomy, and continuous learning.

Ready to launch your career in cloud engineering?

This role offers a hybrid model, with 3 days per week spent working from the client’s office in Kraków, Gdałsk, or Wrocław in Poland.

Responsibilities

• Develop new features and refine existing code to make it cleaner, more readable, and more efficient
• Contribute to the full development lifecycle — from analysis and design through implementation, testing, and ongoing support
• Communicate directly with the client on a daily basis, building strong stakeholder relationships
• Collaborate with experienced engineers and architects on a scalable, high-performance platform
• Continuously learn the project domain and explore new technologies
• Take ownership of your tasks and deliver high-quality solutions on time

Requirements

• 1+ years of experience developing and integrating software through the full system implementation lifecycle (analyze, design, implement, build, test, support)
• 1+ years of hands-on experience with Java
• Solid knowledge of JUnit, Mockito, and SQL
• Strong self-management and prioritization skills
• A proactive, self-starter mindset with a focus on quality and timely delivery
• Excellent English communication skills and confidence in client-facing interactions (you’ll be speaking with stakeholders directly!)

Nice to have

• Experience with Google Cloud Platform (GCP)
• Familiarity with TypeScript
• Knowledge of Guice and Protocol Buffers

We gather like-minded people:

• Top tech minds driving innovation in AI, cloud and digital platform modernization
• Supportive team and an agile, startup-like culture that accelerates your growth
• Hybrid work model designed for collaboration, requiring 3 days a week from the office
• Chance to work abroad for up to 60 days annually

We provide growth opportunities:

• Career development programs
• Thought leadership, mentoring, soft skills and well-being programs
• Certification (Anthropic, Gemini, GCP, Azure, AWS)
• English classes

We cover it all:

• Stable pay
• Participation in the Employee Stock Purchase Plan with a 15% discount
• Benefits package (health insurance, multisport, shopping vouchers)
• Referral bonuses up to $2,000
• Offices featuring entertainment and relaxation zones, table tennis and football, free snacks, coffee and more
• Corporate, social and well-being events

Please, note:
