Job Responsibilities:

• Automate repetitive tasks related to deployments, monitoring, and incident response.
• Implement infrastructure-as-code practices using tools like Terraform or CloudFormation.
• Analyze and interpret large datasets to extract insights and develop predictive models for system performance enhancement.
• Identify performance bottlenecks in systems and applications and utilize profiling tools to analyze resource usage (CPU, memory, I/O).
• Develop and implement data-driven solutions to optimize system parameters and improve throughput and latency.
• Design and implement observability systems for tracking key performance indicators (KPIs) using tools like Prometheus and Grafana.
• Establish and monitor Service Level Objectives (SLOs) and Service Level Indicators (SLIs).
• Create alerts for critical performance issues and incidents.
• Collaborate with development teams to integrate data science solutions into full stack application development.
• Communicate performance insights and recommendations to stakeholders through visualizations, reports, and presentations.
• Mentor junior SREs and data engineers on performance engineering and data-driven best practices.

Required Skills and Qualifications:

• Formal training or certification on software engineering concepts and 5+ years applied experience.
• Proficiency in programming languages such as REXX, Python, or Java.
• Strong understanding of statistical analysis, data engineering techniques focused on monitoring, automation, and continuous improvement ensuring systems are efficient, scalable, and available.
• Experience with data manipulation and analysis using libraries such as Pandas, NumPy, TensorFlow, Scikit-learn, PySpark, or Polars.
• Familiarity with data visualization tools such as Matplotlib, Seaborn, Power BI, or Tableau.
• Knowledge of SQL and experience with database querying.
• Experience with mainframe and mid-range computing platforms.
• Proficiency with cloud platforms (AWS, GCP, Azure) and containerization (Docker, Kubernetes).
• Strong problem-solving, analytical, and communication skills.

Preferred Qualifications:

• 5+ years of experience in data science, SRE, or a related role, preferably in application development.
• Experience with full stack application development and optimizing system performance and reliability through software engineering principles.
