Role Overview
We are seeking a highly skilled and strategic Platform Engineer III to design, build, and optimize the foundational infrastructure that powers our applications and services.

Pipeline Engineering: Architect, maintain, and optimize automated CI/CD deployment pipelines to accelerate delivery and ensure high-quality software releases.

Cloud Management & Observability
Cloud Optimization: Architect and fine-tune cloud environments (AWS, Azure, or Google Cloud Platform) for peak performance, cost-efficiency, and resilience.
Observability & Reliability: Implement comprehensive monitoring, logging, and alerting systems; drive strategies for rapid issue detection and system reliability.
Performance Tuning: Proactively identify and resolve system bottlenecks; optimize platform resource allocation to maximize efficiency.

Security, Compliance & Operations

Incident Management: Participate in on-call rotations, diagnose complex production incidents, and lead rapid resolution efforts to minimize downtime.
Developer Experience: Partner with software engineering and SRE teams to identify workflow friction, streamline developer tooling, and automate routine operational tasks.

Qualifications & Requirements
Minimum Qualifications
Education: Bachelor's degree in Computer Science, Information Technology, Engineering, or a related technical discipline.
Experience Baseline: Minimum of 5 years of professional experience in platform engineering, DevOps, or large-scale infrastructure roles.
Technical Mastery:
oStrong hands-on experience with at least one major public cloud provider (AWS, Azure, or Google Cloud Platform).
oDeep proficiency in Infrastructure as Code (Terraform, CloudFormation).
oExpert-level knowledge of Containerization & Orchestration (Docker, Kubernetes).
oStrong scripting and automation skills (Python, Bash, or Go).
Core Competencies: Strong analytical and debugging skills to troubleshoot complex, distributed systems; ability to work effectively in a collaborative, team-oriented environment.

Preferred Attributes
Proven experience managing observability tools (e.g., Prometheus, Grafana, Datadog, New Relic).
Experience implementing CI/CD with enterprise tools like Jenkins, GitHub Actions, or GitLab CI.
Solid understanding of cloud security standards, network architecture, and compliance frameworks (e.g., SOC 2, ISO 27001).
