Senior Platform Engineer

Job Description
The Platform Engineer serves as a senior technical resource responsible for strengthening cloud security foundations across AWS and Azure through preventive controls, secure network architecture, and CI/CD enforcement. This role is highly hands‑on and designs and implements security platforms in collaboration with Infrastructure Architecture, translating agreed designs and roadmaps into deployable technical standards, automation (Terraform, Python/Power Shell), and operationalized platform capabilities.

Limited on‑call expectations focus on escalation for platform‑level issues.

Key Job Responsibilities
Cloud Foundations

Build and evolve cloud foundations in AWS Control Tower, including baseline standards for account structure, preventive cloud controls, and secure‑by‑default patterns.

Reduce privilege escalation paths by defining and enforcing least‑privilege patterns, privileged role boundaries, and secure administrative workflows for cloud operations and automation.

Improve service/API security through standard patterns for workload/service identities, credential handling, and secure service‑to‑service access with application and platform teams.

Reduce lateral movement risk by implementing cloud network security architecture patterns (segmentation, controlled east‑west paths, and a centralized egress/inspection approach where appropriate).

Collaborate with the Infrastructure Architect on target designs and multi‑quarter roadmaps; implement approved designs through standards, automation, and platform changes.

CI/CD Engineering

Design and implement security‑as‑code and policy‑as‑code enforcement in Git Lab CI/CD for infrastructure and access changes, focusing on preventing high‑risk IAM and network patterns from being deployed.

Standardize secure delivery patterns through reusable pipeline templates/components and Terraform module conventions (PR‑based change control, reviewable outputs).

Secure CI/CD automation identities and secrets usage patterns in pipelines (permissions, separation of duties, and safe credential handling).

Drive adoption across engineering teams by providing clear patterns, documentation, and reference implementations.

Privileged Access & Secrets Platforms

Design, implement, and own Cyber Ark across PAM, EPM, and Secrets Hub: onboarding patterns, access models, rotation workflows, elevation policies, privileged workflows, and platform automation.

Maintain and improve the current MFA/SSO platform as required and support rationalization/consolidation toward the target platform strategy over time.

Provide standardized privileged access and secrets usage patterns that directly support cloud and CI/CD security objectives (automation identities, break‑glass approach, service credential patterns).

Continuous Controls Monitoring & Audit Support

Establish continuous controls monitoring outcomes for cloud and platform controls (control validation, exception identification, and standardized reporting outputs).

Provide and maintain security configurations and audit‑ready outputs for control reviews (cloud controls, CI/CD enforcement controls, privileged access controls), coordinating with control owners as needed.

Translate security requirements into deployable technical standards implemented through established change processes.

Continuous Improvement

Maintain documentation for platform designs, standards, CI/CD enforcement, privileged access workflows, and operational procedures.

Identify control gaps and operational inefficiencies and propose/implement targeted improvements.

Incorporate lessons learned from incidents, changes, and platform issues into standards, automation, and runbooks.

Participate in ongoing professional development to stay current with cloud security engineering practices and platform security tooling.

Minimum Education And/or Experience Required For The Job

5+ years of experience in platform engineering, cloud/infrastructure engineering with security ownership, and/or platform engineering in an enterprise environment.

Demonstrated experience designing and implementing security platforms, partnering with architecture stakeholders to define target‑state designs and…
