Job Summary

We are seeking a Senior AWS Infrastructure & Platform Engineer with deep expertise in designing optimizing and operating cloud infrastructure on AWS. This role is responsible for improving the reliability performance and cost-efficiency of our AWS environments while enabling engineering teams to deploy faster and with greater confidence. The ideal candidate combines hands-on AWS architecture skills with a strategic mindset for infrastructure optimization and a track record of measurable improvements in system performance deployment velocity and cloud spend.

Responsibilities and Duties

AWS Infrastructure Strategy & Cost Optimization

• AWS Platform Strategy: Define and implement the strategic vision for LendKeys AWS infrastructure ensuring alignment with business goals while continuously optimizing for performance reliability and cost.
• Cost Optimization: Proactively analyze and reduce AWS spend using Cost Explorer Trusted Advisor Compute Optimizer and custom reporting. Implement rightsizing Reserved Instance/Savings Plan strategies spot instance utilization and architectural efficiencies to drive measurable cost reductions.
• Infrastructure Efficiency: Identify and eliminate waste across compute storage networking and data transfer. Establish tagging strategies and cost allocation models to drive accountability across teams.

Reliability & Performance Engineering

• System Reliability: Design and implement highly available fault-tolerant architectures across multiple AWS availability zones. Drive improvements to meet and exceed 99.9% SLA through proactive capacity planning auto-scaling and chaos engineering practices.
• Performance Optimization: Continuously profile benchmark and optimize system performance across compute networking storage and database layers. Reduce latency improve throughput and eliminate bottlenecks.
• Disaster Recovery: Design document and regularly test disaster recovery procedures to ensure business continuity across all critical systems.

Deployment Speed & Developer Experience

• CI/CD Pipeline Optimization: Design maintain and continuously improve CI/CD pipelines to minimize build times reduce deployment friction and enable engineering teams to release frequently and safely.
• Deployment Strategies: Implement and manage blue/green canary and rolling deployment patterns to minimize downtime and reduce deployment risk.
• Developer Self-Service: Build internal tooling templates and self-service capabilities that enable engineering teams to independently provision resources deploy services and troubleshoot issues within established guardrails.
• Infrastructure as Code (IaC): Champion Terraform best practices including module development state management code review workflows and automated drift detection to ensure all infrastructure is version-controlled and reproducible.

Monitoring Observability & Incident Management

• Observability: Implement and maintain comprehensive monitoring logging and tracing solutions (e.g. CloudWatch New Relic Prometheus/Grafana OpenTelemetry) to provide full-stack visibility into system health and performance.
• SLI/SLO Framework: Define and instrument Service Level Indicators (SLIs) and Service Level Objectives (SLOs) to create data-driven reliability targets and alerting.
• Incident Response: Lead a rotational on-call schedule. Drive blameless post-incident reviews and implement preventive measures to reduce incident recurrence.

What We Are Looking For

• A hands-on AWS infrastructure engineer who architects and optimizes cloud environments for reliability speed and cost-efficiency.
• A systems thinker who proactively identifies bottleneckswhether in deployment pipelines cloud costs or system performanceand drives measurable improvements.
• A builder who creates tools automation and self-service platforms that multiply the effectiveness of engineering teams.
• A leader who thrives in collaborative environments and can independently drive complex projects from concept to production.
• Someone who stays current with AWS services cloud-native architecture patterns and infrastructure best practices.
• A professional who brings a FinOps mindsetbalancing cost performance and reliability in every infrastructure decision.
