- Participate in shift rotations and on-call support according to the agreed support schedule.
REQUIREMENTS
Must-have
- At least 4 years of experience in Java development, with hands-on experience in Spring and JSP/Servlet.

- Day shift: 9:00 AM - 6:00 PM
- Evening shift: 5:00 PM - 1:00 AM
- Rotation: Two weeks on the day shift, followed by two weeks on the evening shift each month.
On-call support:
- Approximately one week of on-call duty every 1.5 months.

Ideal Candidate Profile
A Senior Java Developer who has transitioned into or gained substantial experience in Application/Production Support, with strong troubleshooting skills, solid SQL Server knowledge, and the confidence to communicate directly with UK-based clients.
