Contract IoT Engineer – AWS IoT Platform Stabilization & Terraform Migration

Engagement Type: Fixed-scope contract Duration: 1-2 months Location: Fully Remote (U.S. time zones) Start: ASAP

Role Overview

We are looking for a senior IoT Engineer to stabilize and harden a production AWS IoT platform. This is not greenfield development. The focus is on issue resolution, Infrastructure-as-Code migration, standardized edge device provisioning, and complete internal handoff.

Key Objectives

• Stabilize production issues (especially SNS notification reliability)
• Migrate entire platform to Terraform (IaC)
• Create repeatable, documented provisioning workflow for InHand industrial edge routers
• Deliver high-quality documentation and knowledge transfer for internal ownership

Technology Stack

• AWS Services: IoT Core, IoT SiteWise, Lambda (Python/Node.js), SNS, CloudWatch, IAM, S3, Managed Grafana
• IaC: Terraform
• Edge Hardware: InHandGo EC942 (or similar industrial routers)
• Tools: GitHub Enterprise

Responsibilities

• Triage and resolve open production issues, prioritizing notification/alerting reliability
• Inventory, import, and migrate all AWS resources into clean Terraform modules with remote state
• Design and document a standardized “cookie-cutter” provisioning process for new edge routers (out-of-box → fully integrated)
• Produce comprehensive documentation: architecture diagrams, runbooks, provisioning guides, and operational procedures
• Conduct knowledge transfer sessions with internal team

Required Skills & Experience

• 5+ years AWS cloud engineering with production support
• Strong hands-on experience with AWS IoT Core and AWS IoT SiteWise
• Advanced Terraform skills (module design, resource import, state management, best practices)
• Experience provisioning industrial edge routers / cellular gateways with certificate-based onboarding
• Proficiency in AWS Lambda, SNS, IAM, CloudWatch, and Grafana
• Strong documentation and knowledge transfer skills
• Experience stabilizing and handing off inherited platforms

Preferred Skills

• Industrial / manufacturing IoT experience
• Cellular fleet management
• Terraform automation (pipelines, custom UIs, or modules)

Deliverables

• Fully stabilized platform with resolved notification issues
• Complete Terraform IaC codebase in GitHub Enterprise
• Repeatable, documented edge router provisioning workflow
• High-quality architecture docs, runbooks, and operational guides
• Successful internal team handoff

This is a high-impact, well-defined engagement ideal for a senior engineer who excels at cleanup, standardization, and handover work.
