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.

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.
