Java Backend Engineer | GNST POD
Location: Burgess Hill (Hybrid: 3 days per week onsite MUST)
Level: Mid-Senior (Up to 5 years experience)
Are you passionate about building high-availability, distributed systems? We are looking for a Java Backend Engineer to join our GNST POD in Burgess Hill. You’ll be at the heart of our development lifecycle, crafting world-class software that powers customer-facing and business-critical applications.
If you thrive in an Agile environment and have a knack for Microservices and Event-Driven Architecture, we want to hear from you.
The Role
As a Software Engineer, you won’t just write code—you’ll help shape our development standards. You will contribute to the design, debugging, and deployment of robust systems using modern distributed frameworks.
Key Responsibilities:
- Build & Scale: Develop high-quality software using Java 11/17 and Spring Boot.
- Quality First: Participate in code reviews, TDD, and automated testing (Cucumber/JMeter).
- DevOps Culture: Enable CI/CD through Jenkins, GitHub, and automated deployments.
- Observability: Monitor and troubleshoot applications using Splunk, Kibana, and Grafana.
- System Design: Scale applications based on demand and contribute to high-availability architecture.
What You Bring
- Core Tech: 5+ years of professional experience with Java (8+, ideally 11/17) and Spring Boot.
- Messaging: Proven experience with Kafka and its ecosystem.
- Data: Proficiency in both SQL (Oracle, PostgreSQL) and NoSQL (Couchbase, Cassandra).
- Architecture: Deep understanding of Microservices and Event-Driven systems.
- Tooling: Hands-on experience with Jenkins, Git, and cloud infrastructure.
Bonus Points for:
- Experience with GoLang (1+ year).
- Knowledge of Reactive Programming (e.g., Vert.X).
- Expertise in Caching mechanisms and high-transaction systems.
- Technical certifications in Java or Cloud technologies.
Why Join Us?
You will work in a collaborative, tech-forward environment where consistent development practices and documentation are valued. This is an opportunity to manage applications with high transactions per second (TPS) and ensure 24/7 availability for our global users.
Requirements:
- University Degree in Computer Science, Engineering, or equivalent experience.
- Ability to work from our Burgess Hill office 3 days a week.
