Participate in root-cause analysis and remediation of production incidents, with a focus on preventing recurring issues.
Develop and improve monitoring, alerting, and observability capabilities to strengthen system health and operational visibility.
Identify and address single points of failure, performance bottlenecks, and operational risks.
Support disaster recovery, business continuity, and platform hardening initiatives.

Application Development & Modernization

Design, develop, and support enterprise applications, APIs, and platform services.
Modernize legacy systems through adoption of contemporary frameworks, architectures, and engineering practices.
Develop integrations between internal systems and enterprise platforms.
Contribute to proof-of-concept initiatives and evaluation of emerging technologies.

DevOps & Automation

Build and enhance CI/CD pipelines to improve software quality and delivery efficiency.
Automate testing, deployment, compliance, and operational processes.
Support containerized and cloud-ready application architectures.

Required Skills

Programming & Software Engineering

Strong programming skills in Java; Java 17 or later is preferred.
Experience with Python and/or JavaScript.
Hands-on experience with Spring Boot and REST API development.
Solid understanding of object-oriented design and software engineering principles.

Security & Platform Reliability

Understanding of secure software development practices and common application security risks.
Familiarity with vulnerability management, dependency upgrades, and remediation activities.
Knowledge of secure coding principles.
Understanding of high-availability, resiliency, and fault-tolerant system design concepts.

Infrastructure & Systems

Good working knowledge of Linux/Unix systems and shell scripting.
Familiarity with networking protocols such as HTTPS, SSH/SFTP, SMTP, TLS, and TCP/IP.
Experience working with relational databases such as PostgreSQL, Oracle, or SQL Server.

Modern Engineering Practices

Experience with Git-based development workflows.
Familiarity with CI/CD pipelines and automated testing.
Exposure to container technologies such as Docker and Kubernetes/OpenShift.

Professional Skills

Strong analytical, troubleshooting, and problem-solving skills.
Ability to investigate complex production issues and drive them to resolution.
Good verbal and written communication skills.
Ability to collaborate effectively in a global team environment.

Preferred Qualifications

Experience with distributed systems and messaging technologies such as Kafka or IBM MQ.
Familiarity with enterprise file transfer platforms and managed file transfer solutions.
Knowledge of cryptography, PGP, key management, and certificate management.
Exposure to cloud platforms such as AWS, Azure, or GCP.
Experience with monitoring and observability tools such as Splunk, Grafana, Prometheus, or OpenTelemetry.
