Job description

Senior Automation Engineer (High-Impact / Mission-Critical Systems)

Role Overview

We are looking for an elite Automation Engineer who can design, build, and own end-to-end automation systems at scale . This is not a script-writing role-you will be expected to engineer resilient, production-grade automation that replaces manual operations across complex environments.

You must operate with strong ownership, anticipate failure scenarios, and deliver automation that is observable, testable, and fault-tolerant under real-world conditions .

Key Responsibilities

Automation Architecture & Engineering

• Design and implement scalable automation frameworks across infrastructure, applications, and workflows
• Build automation using Python (or equivalent), APIs, and event-driven systems
• Develop pipelines for CI/CD, test automation, and operational workflows

Systems Thinking & Reliability

• Engineer automation with idempotency, rollback, and failure recovery mechanisms
• Identify bottlenecks and eliminate manual dependencies at system level
• Ensure automation is production-ready with logging, monitoring, and alerting

Technical Ownership

• Own automation lifecycle from design deployment optimization
• Debug complex failures across distributed systems
• Enforce coding standards, version control, and maintainability

Cross-Functional Impact

• Work with DevOps, QA, Security, and Product teams to automate critical processes
• Challenge inefficient workflows and redesign end-to-end processes
• Deliver measurable impact (time saved, incidents reduced, uptime improved)

Non-Negotiable Requirements

• 5-10+ years in automation engineering (not manual QA or basic scripting)
• Proven experience building production-grade automation frameworks
• Strong programming skills (Python, Java, or similar-not low-code tools)
• Deep understanding of CI/CD, APIs, testing strategies, and system reliability
• Experience working with distributed systems, cloud environments, or large-scale platforms
• Demonstrated ability to debug failures across multiple layers (code, infra, network)

Exceptional Candidate Signals

• Built automation that replaced entire workflows or teams-not just tasks
• Experience with infrastructure as code (Terraform, Ansible)
• Strong grasp of observability (logs, metrics, tracing)
• Proven impact in high-scale or high-availability environments
