AWS Platform Engineer

Job Description – AWS Platform Engineer (Financial Systems)

About the Role

We are seeking a 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-premises 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.

System Ownership & Reliability

Take complete responsibility for assigned financial systems and ensure high availability.

Troubleshoot complex issues across infrastructure, applications, and integrations.

Conduct root cause analysis and implement permanent fixes to prevent recurrences.

Operational Excellence

Design and manage Disaster Recovery (DR) strategies; conduct periodic DR drills.

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.

Hands-on with key AWS services (EC2, ECS / Fargate, RDS, S3, IAM, Lambda, VPC).

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

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

Operational Expertise

Proven experience in patching, DR, backup, monitoring, and system hardening.

Strong troubleshooting skills across applications, middleware, and databases.

Familiarity with incident, problem, and change management frameworks (ITIL preferred).

Preferred

Exposure to financial applications (Front Arena, Calypso, Murex, or similar).

Strong background in automation-driven operations and performance tuning.

Soft Skills

Strong sense of ownership and accountability.

Calm, decisive, and resilient in high-pressure financial environments.

Collaborative, with excellent communication skills across business and technical teams.

Passionate about automation and continuous improvement.
