Senior Cloud Engineer - IoT Data Plane

Role Description

We are looking for a Senior Cloud Engineer – IoT Data Plane to help build the next generation engineering team for our AMI Global brand. This role may work remote, but we would prefer a candidate to be near one of our SJE locations.

As our Senior Cloud Engineer, you will own the data plane end-to-end. Key responsibilities include:

• MQTT broker selection: AWS IoT Core, self-hosted, or managed third-party. There is an open ADR; you will write it.
• Telemetry ingestion at fleet scale: Backpressure, validation, dead-letter handling, surviving the occasional poison-pill payload without taking the platform with you.
• Semantic data model: Raw Modbus comes off the wire and gets normalized at ingest against a versioned, device-type-aware mapping. Alerts, reports, analytics, and customer APIs all read from the normalized form.
• Time-series storage: Engine choice (Timestream, Influx, ClickHouse, or something we haven’t picked yet), partitioning, retention, query patterns.
• Public API contract: Co-designed with our launch customer; versioned, OpenAPI-described, semantic.
• Cost per device and cost per tenant: Instrumented early. Serverless at IoT volumes can get expensive in non-obvious ways.

Qualifications

• Experience building production cloud systems on AWS (7+ years), with deep IoT or large-scale streaming.
• Experience operating a MQTT-based device fleet at 100k devices, or a comparable ingest-heavy streaming workload (Kinesis, MSK, Kafka, etc.) at similar scale.
• Strong opinions on time-series storage trade-offs, based on actual experience.
• Experience writing design documents.
• Fluency in IaC (Terraform or CDK) and CI/CD.
• Experience talking to customer engineering teams directly.
• A 4-year degree in Computer Engineering, Computer Science, Electrical Engineering or equivalent degree and 7-10 years of experience are required.

Requirements

• Bonus Qualifications:
• Industrial IoT or critical-infrastructure background (water, energy, manufacturing, building automation).
• Modbus or other industrial-protocol exposure.
• ISO 27001 or SOC 2 platform experience.
• Multi-account AWS Organizations / Control Tower experience.

Benefits

• Up to 120 hours of Paid Time Off in your first year plus 8 paid holidays.
• Robust benefits package including health, life, short-term and long-term disability insurance, dental and vision programs.
