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.

We partner directly with enterprise teams to embed AI-native practices into delivery by accelerating modernization, reducing risk, and shipping production-grade AI systems that set the standard for the industry.

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 that change how teams operate

- Build platform engineering initiatives within your workstream — developer platforms, self‑service tooling, automated governance, policy as code

- Integrate AI and LLM capabilities into client delivery pipelines and developer workflows in ways that are architecturally sound and maintainable

- Anticipate technical risk before it becomes delivery risk — surface issues early and communicate proactively

- Participate in scoping discussions and SOW architecture for new and existing customers

- Lead or participate in Platform Dojo engagements, coaching client teams on modern delivery practices

- Generate ideas, be willing to fail quick, and demonstrate with POCs

Client Technical Engagement





- - Serve as the senior technical point of contact for your workstream — engaging directly with client engineering managers and directors on architecture, delivery strategy, and technical risk

- Proactively identify opportunities to improve engineering culture, delivery practices, and technical quality at the client, and drive that change

- Participate in business development including client expansion conversations and SOW development

Team Leadership and Development

- - Responsible and accountable for the technical outcomes of your team

- Mentor engineers through real technical challenges — pairing, architecture reviews, feedback that raises their game

- Organize and break down complex work so the team can execute with clarity

Liatrio Growth

- - Identify and surface expansion opportunities to the sales team and validate SOWs

- Build accelerators from client engagement insights that benefit future engagements

Experience and Skills:

Engineering and Infrastructure

- - You have a track record of owning the architectural direction of complex, high-stakes Platform workstreams — you've made the hard calls, been accountable for the outcomes, and learned from the experiences that didn't go as planned

- You've designed and owned CI/CD systems at enterprise scale — defined the strategy, rationalized toolchains, and built governance models that let large organizations move fast without losing control

- You've built and led cloud-native platform adoption in complex production environments — whether that's Kubernetes, managed container services, or other orchestration platforms — and built or overseen the platfo
