About Us: At Liatrio, we enable real transformation. We help industry-leading enterprises break free from legacy systems and adopt AI that reshapes how teams build, deliver, and thrive at scale.

Our people embed directly inside client organizations, leading hands-on AI enablement and transformations that reshape how entire enterprises build and operate at scale. If you’re ready to lead real AI transformation, this is where you belong. About the Role: The Principal Platform Engineer defines the scope of technical work, owns the architectural direction of complex Platform workstreams, and is accountable for the technical outcomes of the engagement. You are responsible for code quality, architecture, and technical direction across your team — and you're the person who makes sure what gets built is the right thing, built the right way. You make the hard architecture calls, document the tradeoffs, and communicate them in a way that builds trust with the engineers executing the work and the technical leaders sponsoring it. What You'll Do: Technical Ownership and Architecture Define the scope of technical work related to deliverables and milestones of the engagement Own the architectural direction of your Platform workstream — CI/CD pipeline design, IaC architecture, platform strategy, observability programs, DevSecOps implementation, AI tooling and implementation, and developer experience Responsible for code quality, architecture, and technical direction across the team Build and own complex delivery infrastructure — pipelines teams depend on, IaC systems that don't drift, and cloud-native platform environments that work for teams who aren't infrastructure specialists Drive observability maturity — implementing metrics, logging, tracing, and alerting strategies t
