Sr. Platform Engineer

Job Description

Job Description

Our valued client in the Denver Tech Center is seeking a Sr. Platform Engineer for their team. This is a hybrid role that requires you to reside in the Denver-Metro area. This engagement is a six-month contract-to-hire opportunity.

Position Summary

A senior, hands-on platform engineer with ownership across the whole internal developer platform: infrastructure, CI/CD, observability, security, and cost, not just one slice of it. This role carries more scope and more independent judgment than the Platform Engineer role, and may informally point the technical direction for other engineers on a given project, without a formal management title.

Key Responsibilities

• Own the internal developer platform (IDP): drive the design and evolution of the self-service workflows, the Golden Paths, that the rest of engineering relies on

• Lead infrastructure as code practice: set the standard for how the team provisions and manages infrastructure, and build the automation others follow

• Own CI/CD architecture: design and evolve the build, test, and deployment pipelines the platform depends on, including how GitOps practices get applied

• Drive observability strategy: make sure the platform is monitored, logged, and traced well enough that problems surface before anyone has to ask

• Own performance reporting: build and maintain the metrics and reporting layer that shows leadership and the rest of the organization how the platform is performing month to month

• Set the security and access standard: establish how secrets, access control, and role-based access control (RBAC) get handled across the platform

• Own platform cost and efficiency: track spend and bring cost-efficiency recommendations forward

• Guide other engineers: give informal technical direction and review to the rest of the team

Required Qualifications

• Programming and automation: strong Python skills and a track record of building real automation and integrations at production scale

• Cloud and containers: deep experience with a major cloud provider (AWS or Azure) and containerized infrastructure running in production

• CI/CD and delivery practices: considerable experience owning pipelines end to end, including secure, modern deployment practices

• Infrastructure as code at scale: experience running IaC practices, such as Terraform, across a real production environment

• Security mindset: bake security into everything you build and hold the rest of the team to the same standard

• Cost awareness: experience applying FinOps or similar cost-management practices to cloud spend at scale

• Reporting and transparency: track record of building metrics or reporting capability that gives leadership and other teams real visibility into platform performance

• Working with developers: track record of treating the platform's users as customers and adjusting the platform based on their feedback

Preferred Qualifications

• Experience informally mentoring or guiding other engineers

• Experience with hybrid on-premises and cloud environments

• Experience with observability or log management platforms

• Exposure to cloud cost management or FinOps practices

Certifications are a plus but not required. Hands-on experience is weighted more heavily
