Dive into the pulse of cutting-edge solutions with Patrianna LTD! 🚀
We’re looking for a Middle Java Developer (Back Office) with a product-oriented mindset — someone who doesn’t just implement specs, but actively thinks about how to make internal systems intuitive, efficient, and genuinely enjoyable to use.
🌟 Who We’re Looking For!
You’ll be working on our backoffice solution, the core interface that powers internal operations across compliance, risk, support, and more. It’s built on Retool, but we don’t expect you to have experience with it — what matters most is your ability to design smooth workflows and craft usable, scalable solutions for non-technical users.
This role is perfect for someone who is absolutely passionate about convenient user experience — maybe even a bit obsessive when it comes to workflow clarity, interface logic, and eliminating friction. You’ll treat internal users with the same care and respect a product designer would treat end users — because their experience matters just as much.
If you take pride in simplifying complexity, love creating tools that people actually want to use, and think good UX is a competitive advantage — we’d love to hear from you.
Responsibilities:- Build and evolve our internal backoffice solution using Retool and custom APIs.
- Design and develop fullstack features that connect frontend logic (in Retool) with backend APIs and data layers.
- Understand how internal (admin) users work — and improve that experience through thoughtful UX and workflow design.
- Work closely with stakeholders to identify inefficiencies, gather feedback, and translate it into impactful features.
- Write clean, well-tested, maintainable code across both frontend (Retool) and backend stacks (Java/Spring Boot).
- Take ownership of the reliability, security, and usability of the backoffice system.
- Proactively challenge unclear requirements and suggest smarter, more elegant approaches.
- 3+ years of production experience with Java and its ecosystem
- Eagerness to work as a fullstack developer with ReTool for GUI and Java for backend (prior experience with ReTool is not required)
- Strong proficiency in Java, with a solid grasp of JVM internals and performance considerations
- Good understanding of relational database principles, preferably with hands-on experience in PostgreSQL
- Familiarity with messaging systems and asynchronous processing, ideally within the Kafka ecosystem
- Solid knowledge of concurrency and multithreading concepts, including practical application in real-world systems
- Strong sense of user experience and workflow design — not just functional correctness, but clarity, flow, and usability
- Ability to collaborate with non-technical stakeholders, understanding business needs, and translating them into practical technical solutions
- Clear communication skills and a demonstrated sense of ownership and initiative
- Upper-intermediate English or higher — capable of confidently discussing both technical and UX-related topics in cross-functional settings
- Experience with ReTool or similar platforms
- Experience in full-stack development, especially in B2B or internal-facing systems
- A keen eye for UI/UX quality — attention to layout, clarity, consistency, and overall ease of use
- Java 23
- Spring Boot 3.4.6
- Google Cloud Platform:
- Kubernetes
- Kafka
- AlloyDB for PostgreSQL
- Spanner
- Ebean ORM
- Flyway
- Redis
- Quartz
- Websockets
- Retool
- Test Containers
- Locust for perf testing
- Jenkins/ArgoCD
- ELK/Sentry/Grafana
- Jira/Confluence/Slack/Bitbucket
