[Hiring] Mid/Senior Java Developer @CI&T

Role Description

We're assembling a small team to take over a set of backend services that power a direct-to-consumer commerce platform of a global beverage/consumer goods company. The mission for this phase is clear: keep the lights on. Absorb these services fast, keep them stable through the highest-demand period of the year, and leave them better documented and tested than we found them.

What You'll Be Doing:

• Own a portfolio of forked backend services (mostly Java/Spring Boot): bug fixes, small changes, and day-to-day stability.
• Drive knowledge transfer with the original team through shadowing sessions.
• Build service context documentation in three layers (business rules, application behavior, operations) following the client's template.
• Support incidents in a production environment that runs 24/7 across global markets.
• Work within an Azure-based infrastructure, contributing to the duplication and adaptation of CI/CD pipelines.
• Participate in the team's shift toward better engineering practices.
• Help classify services by technical criticality and flag systemic risks early.

Qualifications

• Hands-on use of AI-assisted development tools in real work.
• Java (backend, production experience) — this is non-negotiable.
• Spring Boot — the core framework across the service landscape.
• REST API design and integration.
• Azure DevOps — familiarity with pipelines, repos, and environments.
• Non-relational (CosmosDB for MongoDB) and relational databases (PostgreSQL).
• Testing — JUnit for unit tests; familiarity with E2E or integration testing.
• Incident response mindset — ability to diagnose, triage, and resolve issues in complex distributed systems under pressure.
• English — for reading documentation, participating in cross-team calls, and written communication.
• Hands-on experience operating and debugging distributed microservices in production.
• Clear, proactive communication.
• Comfort working on inherited/legacy code with a "understand first, change carefully" mindset.

Requirements

• Experience with microservices at scale.
• Azure cloud services beyond DevOps.
• Familiarity with DDD (Domain-Driven Design) concepts.
• Go — a secondary language used in some newer services.
• Understanding of internationalization and global commerce.
• Performance optimization experience in high-throughput environments.

Benefits

• Health and dental insurance.
• Meal and food allowance.
• Childcare assistance.
• Extended paternity leave.
• Partnership with gyms and health and wellness professionals via Wellhub (Gympass) TotalPass.
• Profit Sharing and Results Participation (PLR).
• Life insurance.
• Continuous learning platform (CI&T University).
• Discount club.
• Free online platform dedicated to physical, mental, and overall well-being.
• Pregnancy and responsible parenting course.
• Partnerships with online learning platforms.
• Language learning platform.
• And many more!
