Senior Java Engineer to join a general SaaS product that's scaling fast and moving into a more mature, reliability?focused phase.
The platform handles a high volume of data and workflows used by customers across multiple countries. The team is strengthening its foundations to ensure stability, consistency and long?term scalability — and they're looking for someone who can take a leading role on the Java side.
You'd become the Java reference point
: someone who can set technical direction, build new services with
Java + Spring + PostgreSQL
, and help elevate the platform's engineering standards. There's also some existing functionality in
Node.js
, and part of the work involves gradually moving that logic into the new Java?based architecture.
This isn't a "ship fast and patch later" environment.
Quality matters: clean architecture, solid testing, strong patterns, observability, and a product that needs to behave predictably for demanding clients.
What you'll do
Design and build backend services using Java + Spring
Bring architectural vision, patterns, and best practices
Help migrate existing Node.js components into the new Java stack
Work with clean/hexagonal architecture and rich domain models
Collaborate with a senior team and a technically strong CTO
Make autonomous technical decisions that shape the platform
Requirements
6+ years of experience working with
Java in complex or high?reliability environments
Strong expertise with
Spring and the ability to design services from scratch
