Job description

Senior Java Developer (Coffee, Code, and Complexity)

We’re looking for a Senior Java Developer who knows that Java is more than just a drink and that NullPointerException is a rite of passage. If you enjoy building robust systems, arguing over the merits of different garbage collection algorithms, and occasionally wondering why everything in Spring needs twenty annotations, we want to talk to you.

The Role

At CloudStream Nexus, we don’t just write code; we build the digital infrastructure that keeps our clients from losing their minds. You’ll be joining our Core Systems team to scale our microservices architecture and ensure our uptime is so high it’s statistically suspicious.

What You’ll Be Doing

• Architecting & Scaling: Designing high-throughput, low-latency APIs using Java 17+ and Spring Boot.
• Microservices Orchestration: Managing a fleet of services that actually talk to each other (most of the time).
• Legacy Love: Occasionally diving into a monolithic codebase from 2014 to perform “digital archaeology.”
• Code Quality: Reviewing PRs with a keen eye for detail and a heart full of empathy.
• Problem Solving: Debugging production issues that only seem to happen at 4:30 PM on a Friday.
