Description
ROLE SUMMARY
The Senior Cloud Engineer is a technical leader within the Cloud Engineering organization, responsible for designing, building, and evolving secure, scalable, and highly automated cloud platforms across a multi-cloud environment. This role plays a critical part in defining cloud standards, reference architectures, and engineering best practices that enable product teams to deliver reliable, well architected solutions at scale.
The ideal candidate brings deep hands-on cloud engineering expertise, strong Infrastructure as Code and automation skills, and the ability to influence platform direction through technical leadership, mentorship, and architectural contributions.
ROLE RESPONSIBILITIES
Cloud Engineering & Architecture
Design, implement, and evolve cloud infrastructure across AWS, Azure, and/or GCP, aligning with enterprise architecture principles and security standards.
Lead the development and maintenance of Infrastructure as Code using Terraform, OpenTofu, or similar tools, ensuring consistency, scalability, and reusability.
Own and enhance reusable cloud modules, patterns, and reference architectures used across the organization.
Partner with architects and senior stakeholders to define secure, resilient, and cost‑efficient cloud designs.
Review and provide guidance on cloud designs and IaC contributions from other engineers.
Platform Automation & Tooling
Design and implement end‑to‑end automation for cloud provisioning, configuration, and lifecycle management.
Lead improvements to CI/CD and IaC automation pipelines using platforms such as Spacelift, GitHub Actions, or equivalent tooling.
Drive initiatives to improve deployment reliability, reduce configuration drift, and increase platform self‑service.
Evaluate and introduce new tooling or approaches that improve developer experience and platform maturity.
Security, Compliance & Operations
Define and enforce cloud guardrails, policies, and controls to ensure secure and compliant platforms.
Integrate security and compliance requirements into IaC and automation workflows (policy as code).

Lead troubleshooting efforts for complex cloud infrastructure issues and perform root cause analysis for incidents.
Collaborate with security, risk, and compliance teams to support audits, regulatory requirements, and governance initiatives.
Collaboration & Continuous Improvement
Act as a technical mentor for Cloud Engineers, supporting skill development and engineering best practices.
Collaborate closely with application teams, SRE, security, and architecture to deliver end‑to‑end cloud solutions.
Drive platform modernization initiatives, identifying opportunities to automate, optimize, standardize, and simplify.
Contribute to technical documentation, standards, and knowledge sharing to uplift cloud engineering maturity.
Participate in architectural discussions and influence platform strategy through well‑reasoned technical proposals.
BASIC QUALIFICATIONS
Bachelor’s Degree in Computer Science, Engineering, IT, or equivalent practical experience.
5+ years of hands-on cloud or platform engineering experience.
Strong proficiency in at least one major cloud provider (AWS, Azure, or GCP), with production scale experience.
Advanced experience with Infrastructure as Code (Terraform strongly preferred).
