OCI Merino CI/CD Platform

Team: OCI – Merino Engineering
Role: IC3 Backend Engineer / Senior Software Engineer
Experience: 4–7 Years – Mandatory
Location: Bangalore – Mandatory
Work Type: Hybrid

Team:

The Merino team within Oracle Cloud Infrastructure (OCI) builds OCI's internal CI/CD change workflow platform for reliable software build, validation, approval, and deployment.

Merino helps OCI engineering teams improve:

• Release automation
• Deployment safety
• Developer productivity
• Change and deployment workflows
• Platform reliability
• Operational excellence

This is a backend/cloud platform engineering team, not a traditional DevOps-only team. The engineer will build the microservices and distributed-system capabilities behind the CI/CD platform.

Roles and Responsibilities:

• Design and develop scalable Java-based microservices and distributed backend services for the Merino platform.
• Build cloud-native capabilities supporting CI/CD, build, validation, approvals, change management and deployment orchestration.
• Take end-to-end ownership from architecture/design through coding, testing, deployment, monitoring and production support.
• Design reliable and maintainable REST APIs and service integrations.
• Develop integrations across build systems, release management, approvals, rollback and deployment workflows.
• Build services with strong focus on scalability, reliability, security, fault tolerance and maintainability.
• Participate in architecture, HLD/LLD, design reviews, code reviews and technical planning.
• Participate in on-call/production support and troubleshoot service, API, integration and distributed-system issues.
• Perform debugging and root-cause analysis (RCA) and implement permanent fixes.
• Drive operational excellence through automation, testing, monitoring, observability and reliability improvements.
• Handle system upgrades, patching and remediation of critical vulnerabilities.
• Work with internal customers/stakeholders, understand their requirements/issues and provide effective technical solutions.
• Independently own deliverables and ensure timelines and quality expectations are met.
• Apply modern development practices, including AI-assisted development, while maintaining production-quality coding, testing and security standards.

Mandatory Skills

1. Microservices

Strong hands-on experience in:

Microservices architecture + distributed backend systems + REST APIs + system/service design

Candidate should have actually designed/developed microservices, not merely worked in an application that uses microservices.

2. Cloud

Hands-on experience developing/deploying production services on at least one major cloud:

OCI / AWS / GCP / Azure

Should understand cloud-native service development, deployment and production operations.

3. Java Programming

Strong hands-on Java coding is critical.

Look for:

Core Java + Spring Boot + REST APIs + multithreading/concurrency + design patterns + debugging + testing

Candidate should be capable of independently designing and coding backend services.

4. End-to-End Ownership

Candidate should demonstrate:

Design → Development → Testing → Deployment → Monitoring → Production Support

This is particularly important for Merino. The candidate should not be someone who only develops features and hands them over to another team.

Good to Have Skills

• CI/CD platform or developer-platform engineering
• Jenkins / GitHub Actions / GitLab CI or similar
• Docker and Kubernetes
• OCI / AWS / GCP / Azure
• Kafka / Pub-Sub / SQS or other asynchronous/event-driven technologies
• Distributed systems
• System Design / HLD / LLD
• Release automation
• Deployment orchestration
• Change-management workflows
• Rollback strategies
• Progressive delivery
• Infrastructure/deployment automation
• Observability and monitoring
• Prometheus / Grafana / Splunk / Datadog
• Retry, idempotency, fault tolerance and resiliency patterns
• Security scanning and vulnerability remediation
• API versioning and lifecycle management
• AI-assisted development using Cursor, Claude Code, Codex, GitHub Copilot or similar
• Experience reviewing/testing AI-generated code for production use

4–7 year hands-on Java Backend Engineer who has designed Spring Boot microservices/distributed systems on AWS/GCP/Azure/OCI and owns services end-to-end from design and coding through deployment, monitoring and production/on-call support. CI/CD/platform engineering exposure is highly preferred.
