Emporix is an AI-driven Autonomous Commerce Execution Platform that gives enterprises full control over how their commerce works. It orchestrates operations end-to-end—so companies can scale faster, respond smarter, and deliver better customer experiences.

We are looking for a skilled Java Developer to join our team in Poland, with a passion for building secure, scalable, and high-performance backend systems. In this role, you’ll focus on leveraging Java and modern frameworks to develop innovative solutions, ensure system security, and work with cutting-edge cloud technologies. If you’re excited about microservices architecture, secure coding, and modern DevOps practices, we’d love to hear from you.

You can work from our modern office in Gliwice or remotely from anywhere in Poland, with a visit to the office at least once per month to meet the team.

What You’ll Be Doing

• Build and maintain scalable backend systems and APIs using Java.
• Design and implement microservices architectures to ensure reliability and scalability.
• Use frameworks such as Spring Boot or Micronaut to implement modular and efficient services.

Security Implementation

• Apply best practices in secure coding and ensure compliance with OWASP standards.
• Regularly scan for vulnerabilities using tools like OWASP Dependency-Check and mitigate identified risks.

Cloud Integration

• Deploy and optimize backend services on Google Cloud Platform (GCP) using Kubernetes, Cloud Storage, and Compute Engine.
• Contribute to the design of cloud-native, high-availability architectures.

Collaboration and Optimization

• Work closely with cross-functional teams, including frontend developers and system architects, to deliver robust solutions.
• Continuously enhance system performance for high availability and fault tolerance.

Documentation

• Produce detailed documentation for system architecture, APIs, and security protocols to ensure long-term maintainability.

What We’re Looking For

• Experience: You have 4+ years of hands-on experience with Java development and building large-scale, high-performance backend systems.
• Education: You hold a degree in Computer Science, Computer Engineering, or a related technical field (or equivalent practical experience).
• Architecture: Proven experience designing microservices-based systems optimized for complex or data-intensive environments, with familiarity in Event Sourcing and distributed system patterns.
• Cloud & Databases: You have hands-on experience with Google Cloud Platform (including Kubernetes and Compute Engine), NoSQL databases (especially MongoDB), and messaging systems (like Pub/Sub).
• Integrations: Experience with integration and workflow systems like Make or n8n.
• Security: Strong understanding of OWASP standards, encryption, and secure coding practices.
• Mindset & Autonomy: You are able to work autonomously while delivering innovative, AI-enabled backend solutions.
• Communication:You communicate effectively in both Polish and English (minimum B2 level).

Bonus Points (What Else Might Help You Succeed?)

• Additional Languages: Experience with Go is a plus.

Why You’ll Love It Here

• An Amazing Team & Culture (Our Best Asset!): We aim high and build rapidly, but we do it together. You will join an incredible, high-trust, and psychologically safe workplace where people truly care for one another. We collaborate closely, support each other unconditionally, and genuinely have fun doing what we do.
• Cutting-Edge Technology: Work on advanced microservices architectures and leverage the latest tools in cloud computing, DevOps, and AI to create groundbreaking solutions.
• Autonomy and Innovation: Enjoy the freedom to explore new ideas, experiment with innovative technologies, and influence the technical direction of a rapidly growing company.
• Flexible Work Setup: Enjoy a hybrid work model that promotes flexibility and personal well-being while encouraging collaboration and meaningful team connections. (Meet in our Gliwice office at least once a month.)
• Impactful Contribution: Be part of a company where your work directly impacts the success of a next-generation commerce platform used by top-tier businesses.

Come as you are: We are building an AI-driven future for commerce, and above all, we believe great software is built by great teams. Most importantly, we look for good people who work exceptionally well together—proactive, positive team players who bring great energy to problem-solving.
