Java Software Engineer

Náplň práce, právomoci a zodpovednosti:
#We have a hybrid set up with possibility to work from Bratislava or Zilina office#

Would you like to leave your mark in the truly booming #cloud-native & fin-tech industry#? Would you like to show your ideas and bring them to life?

With an abundance of technical challenges to be solved with our #cloud-based# core banking, Ohpen is on the lookout for #a skilled Senior Java Developer# to join the team and help us build and maintain the product and its applications. There is where you come into the picture!

Briefing
Join a small, domain-focused team that owns its service end to end. You’ll design and build backend systems in #Java (Spring Boot)#, run entirely in #AWS#, and ship your work to production regularly. Expect full responsibility for your code: development, test automation, deployment, and monitoring.

You’ll automate everything: infrastructure with Terraform, pipelines via GitHub Actions, and tests with #JUnit#. You’ll also be part of regular code reviews and architecture discussions, contributing to a high standard of quality across the team.

#Our Tech Stack#
#Languages & Frameworks#: Java 21+, Spring Boot
#Infrastructure#: AWS, Terraform, Docker
#DevOps#: GitHub Actions, Feature Flags

#About You#
• You have 5+ years experience working in #Java# or similar languages like #C++, Go or Rust#
• You have a solid grasp of #AWS services (EC2, Lambda, Load Balancers, IAM, S3)#
• You should be confident using #infrastructure-as-code# and modern #CI/CD tooling#
• You understand testing beyond unit tests, including integration and contract testing
• You care about product quality and reliability, and you don’t need a QA to point out things you could catch yourself
• You’ll be expected to write and review code in English — and occasionally argue in a pull request.


#How We Work#
We don’t do sprints or ticket factories. We deliver whatever we deem best value/effort, release biweekly (for now), and constantly work to shorten feedback loops. Developers write code, tests, and deploy. Each team has one QA and one DevOps - no handovers, no walls to throw things over.

Everyone is expected to contribute to #architecture and design#. Bureaucracy is kept to a minimum. If something slows us down, we fix it.

#About Us#
We’re building a real-time, cloud-native core banking platform for two major markets. No legacy systems. Just real customers, real code, and real impact. You’ll work in small, strong teams of engineers who care about their craft.
