Job Summary :

Amtech is executing an all-in AWS strategy : migrating our flagship Encore ERP to a multi-account, account-per-customer AWS architecture, operating LabelTraxx as a multi-tenant SaaS platform, and retiring legacy private-cloud infrastructure. Platform Engineering owns the landing zone, infrastructure as code, and the golden-path tooling that product teams build on.

The Principal Platform Engineer is Amtech's senior-most hands-on cloud technologist. You will own the technical architecture of our AWS platform : the landing zone, the account-per-customer Encore hosting model, the golden-path IaC stack, and the migration roadmap that retires our remaining private-cloud footprint.

This role carries organization-wide technical authority without people management. You will make the architecture decisions that hold for years, de-risk them through prototyping and review, and raise the engineering bar across a distributed U.S. and India team. You will also be a primary technical interface to AWS, consulting partners, and executive leadership.

Job Description :

Architecture & Technical Strategy :

- Own end-to-end AWS platform architecture : multi-account organization design, landing zone, networking, DNS and certificate architecture, identity, and tenancy model.

- Set the technical roadmap for Encore-on-AWS environment builds (temp, production, demo) on a shared golden IaC stack, and for LabelTraxx platform evolution.

- Define the migration architecture and sequencing that completes Amtech's exit from legacy private-cloud infrastructure.

- Write and defend architecture decision records; kill weak options early with evidence.

- Evaluate and integrate emerging capabilities, including AI/agentic tooling and MCP-based integration patterns, under Amtech's AI governance program.

Platform Engineering & Delivery :

- Author the highest leverage Terraform modules and reference implementations personally; review the rest.

- Set standards for CI/CD (GitHub Actions), progressive delivery, environment promotion, and secrets management.

- Design for reliability with SRE-track peers : SLO frameworks, observability architecture (OpenTelemetry, OpenObserve), and PagerDuty service models.

- Drive platform cost architecture with FinOps : tenancy economics, Savings Plans strategy input, and unit cost visibility.

Security, Compliance & Risk :

- Design security architecture with Information Security : IAM boundaries, network segmentation, encryption, and data governance for customer data.

- Ensure the platform satisfies SOC 2 and ISO 27001 obligations by design, with audit evidence generated through automation.

- Assess and articulate technical risk for executive decisions : migration sequencing, vendor dependencies, and single points of failure.

AI Competency :

- Design agentic and AI-assisted engineering workflows with autonomy tiers, policy-as-code guardrails, rollback, and end-to-end auditability; measure ROI against baselines.

- Define platform AI standards : where AI sits in the delivery lifecycle, validation layer architecture (schema, rules, model-graded, human review), and evaluation harnesses.

- Prevent AI-generated code from degrading platform quality at fleet scale : eval harnesses, complexity metrics, and AI-attributed defect tracking.

- Contribute to enterprise AI strategy and standards under Amtech's AI governance program.

Technical Leadership & Influence :

- Mentor senior engineers and raise design-review quality across U.S. and India pods.

- Serve as the senior technical counterpart to AWS, consulting partners, and third-party providers on funded programs.

- Translate platform strategy into terms executives and investors can act on; support diligence and integration work for acquisitions.

- Ensure knowledge is durable : documentation, runbooks, and deliberate succession of critical knowledge, avoiding single-person dependencies.

Qualifications :

- 10+ years of progressive engineering experience with deep AWS platform expertise; recognized as the strongest technologist in prior roles.

- Proven ownership of multi-account AWS architecture at organizational scale (landing zones, Control Tower or equivalent, account vending, SCPs).

- Expert Terraform and IaC program design : module ecosystems consumed by multiple teams, testing, and versioning strategy.

- Demonstrated success architecting and executing large migrations (data center or private cloud to AWS), including ERP-class or other stateful enterprise workloads.

- Strong software engineering foundation (Python, Go, or similar) and fluency with modern CI/CD (GitHub Actions or equivalent).

- Working command of cloud security architecture and compliance-driven design (SOC 2, ISO 27001).

- Track record of technical leadership without formal authority : mentoring seniors, driving decisions through writing and review, and influencing executives.

- Designed AI-assisted or agentic engineering systems with guardrails, autonomy tiers, and measured ROI; L4+ AI competency by industry frameworks.

- Bachelor's degree in computer science, Engineering, or a related discipline, or equivalent demonstrated skills.

Preferred Qualifications :

- AWS Certified Solutions Architect Professional or DevOps Engineer Professional.

- Experience with multi-tenant SaaS and account-per-customer tenancy economics.

- Experience in private equity portfolio, M&A integration, or investor-facing technical diligence contexts.

- Experience establishing AI/LLM platform capabilities or agent-based automation under formal governance.

- Experience directing consulting partners on funded cloud programs (for example AWS MAP).
