Java Backend Developer

This position is with Cincom Systems, a subsidiary of PartnerOne, and will be on the HeadSpin payroll.

ABOUT THE ROLE

• 4-5 years of experience

Reports To

• Head of Eloquence Product Engineering, Support & Services
• If you are a Java developer, with a Data & Performance focus, who likes to go beyond REST endpoints and DTOs, and you enjoy understanding how data really flows through a system, this role is for you.
• You will work on a mature, production-proven platform where:
• Databases matter
• SQL matters
• Performance matters
• Design decisions have visible, real-world impact

This role exists following the retirement of a long-standing engineer with deep system knowledge. We are not looking for a like-for-like replacement, but for a sharp, curious developer who enjoys understanding complex systems and making them better.

• You’ll be at the intersection of Java backend development and database engineering, with real ownership and room to grow.

KEY RESPONSIBILITIES

• Database & Data Access (Core Focus)
• Work directly with PostgreSQL and/or SQL Server (Oracle experience also welcome) • Design, analyze, and improve database schemas used by long lived applications • Write and optimize SQL queries for performance and scalability
• Understand execution plans, indexes, locking, and transactions
• Investigate and solve real production performance issues
• Learn how large datasets behave under load and how to make them faster
• If you enjoy knowing why something is slow — not just that it’s slow — you’ll feel at home.

Java Backend Development

• Develop backend services in Java using the Spring ecosystem
• Use Hibernate / JPA with an understanding of their strengths and pitfalls
• Decide when ORM is helpful and when SQL is the better tool
• Work on a stable but evolving codebase where improvements are welcome
• Contribute to design discussions with a strong data - centric perspective.

WHAT WE'RE LOOKING FOR

Essential Experience

You are likely a good fit if you

• Are a strong Java backend developer
• Enjoy working close to the database, not just through abstractions
• Like understanding existing systems instead of rewriting everything
• Care about performance, correctness, and data modeling
• Are comfortable working remotely with international colleagues
• Enjoy technical challenges that require thinking, not just implementing tickets.

Technical Skills

• Solid experience with Java
• Good knowledge of the Spring Framework
• Hands - on experience with Hibernate and JPA
• Strong interest in SQL and relational databases
• Experience with PostgreSQL and/or SQL Server (Oracle is a plus)
• Willingness to dive into performance tuning and data - heavy problems.

Desirable

• Experience with data - intensive or performance - sensitive systems
• Exposure to the CCM (Customer Communications Management) domain
• Experience evolving or maintaining long - running production systems
• Curiosity about how systems behave at scale.
