Job description

You’re a Production Support specialist who believes that the true test of software happens after the \"Go-Live\". You are the guardian of system stability, an expert troubleshooter, and a calm voice during critical incidents. You don’t just restart services; you dig into the code and data to understand why things failed, ensuring that our clients’ web solutions are resilient, observable, and high-performing.

Core Responsibilities:

• Production Monitoring & Health: Proactively monitor application health and performance using Datadog and cloud-native dashboards. Identify trends before they become outages.
• Incident Management & Resolution: Act as the primary responder for application incidents. You will diagnose, mitigate, and resolve issues across Python, Java, and SQL layers to minimize business impact.
• Deep-Dive Root Cause Analysis (RCA): Conduct thorough investigations into recurring issues. Partner with development teams to implement long-term fixes and prevent future occurrences.
• Cloud Operations & Deployment: Support applications hosted on AWS. Assist in the deployment of new releases and patches via CI/CD pipelines, ensuring safety and rollback readiness.
• System Optimization: Analyze application performance and implement tuning measures (SQL optimization, resource scaling) to ensure system sustainability.
• Operational Excellence: Identify opportunities to automate manual support tasks (toil). Maintain high-quality runbooks and technical documentation for the support knowledge base.
• Stakeholder Engagement: Provide clear technical support to end-users and communicate effectively with diverse stakeholders during high-pressure situations.

What you bring:

• Only Singaporeans may apply due to the nature of the project.
• Experience: At least 5 years of hands-on experience in application support or production engineering.
• Technical Proficiency:
• Languages: Strong command of SQL
• Environment: Deep familiarity with Unix/Linux systems and shell scripting.
• Cloud & Tools: Hands-on experience with AWS and Git.
• DevOps Literacy: Understanding of CI/CD pipelines and the Systems Development Life Cycle (SDLC).
• Mindset: An Agile, fast learner who enjoys complex problem-solving and works well in a collaborative team environment.
