Job description

Role overview

Senior platform engineer role focused on building the foundational infrastructure that lets a growth product engineering organization move quickly and safely. The position centers on enabling AI-assisted and agentic development by owning hardened CI/CD pipelines, infrastructure-as-code migrations, account isolation, and centralized observability across an AWS-based stack. It is a hands-on, high-leverage engineering role rather than a people-management position, reporting into the growth product engineering organization.

Responsibilities

• Design and own hardened CI/CD pipelines with pipeline gates, security scans, mutation and end-to-end tests, performance and cost regression checks, and progressive delivery with automated rollback
• Provide a fast, safe inner-loop developer experience through episodic per-PR environments, including isolated databases seeded with realistic data
• Build centralized logging, monitoring, and alerting across the AWS footprint, with automated rollback for bad deployments
• Lead security engineering work: remediate vulnerabilities, establish secure-by-default patterns, and automate code scanning, secrets handling, and access management
• Migrate hand-built AWS resources into infrastructure-as-code, separate production from pre-production accounts, and stand up tested backup and disaster recovery with clear RTO and RPO targets
• Construct paved-path, self-service tooling plus standardized blue/green, canary, and feature-flag releases, while mentoring peers

Requirements

• Strong hands-on background with CI/CD systems, infrastructure-as-code, and AWS at scale
• Proficiency in Python and JavaScript (Vue), with experience using GitHub Actions workflow APIs
• Familiarity with serverless and container-based services alongside internally hosted workloads
• Comfort designing secure-by-default patterns and embedding security into developer workflows
• Demonstrated mentorship and technical leadership experience

Nice to have

• Experience building or operating AI agents for SRE work such as alert triage, incident investigation, or safe self-healing remediation
• Background migrating legacy AWS resources into codified, repeatable infrastructure

Benefits and work setup

• Remote-friendly within the United States, excluding San Francisco Bay, NYC, and Washington D.C. metros
• Flexible working model that supports office-based, hybrid, and fully remote arrangements based on team and operational needs
