Our Employee Value Proposition

Role Description

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.

KEY RESPONSIBILITIES

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 (Open Telemetry, Open Observe), 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.

SKILLS & 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).
