Senior AWS Platform Engineer

Job Description – AWS Platform Engineer

About the Role

We are seeking a AWS Platform Engineer to take full ownership of mission-critical financial systems within an investment banking environment. This role is not a traditional “support” function—it requires a hands-on engineer who can ensure system resilience, reliability, and operational excellence across on-premise and AWS-hosted environments.

The ideal candidate is a hardcore technical engineer who can automate, troubleshoot, and optimize platforms end-to-end while driving operational maturity.

Ensure timely patching, upgrades, and compliance with security standards.

Define and manage backup and restore strategies.

Build monitoring, logging, and alerting frameworks to proactively detect issues.

SRE & Automation

Apply site reliability engineering principles to improve system performance and resilience.

Automate operational tasks (deployments, failover tests, log analysis, scaling).

Develop tooling and scripts (Python, Shell, Ansible) for efficiency and reliability.

Implement self-healing mechanisms and runbooks for predictable operations.

Cloud & Hybrid Environments

Engineer and operate systems deployed on on-prem and AWS platforms.

Leverage key AWS services such as EC2, ECS / Fargate, RDS, S3, CloudWatch, IAM, Lambda, and VPC networking.

Work closely with infrastructure teams to optimize scalability and performance.

Strong automation and scripting skills (Python, Shell, Ansible, and Terraform preferred).

Proficiency in monitoring / observability tools (CloudWatch, Prometheus, Grafana, ELK, etc.).

Operational Expertise
