Amazon Encoder Jobs in Tennessee (NOW HIRING)

Amazon's Mobility and Devices (MAD) team is seeking a Systems Development Engineer III to design, build, and own the platform automation behind an 800K+ mobile device fleet spanning scanners, printers, tablets, and wearables across 3,000+ fulfillment sites worldwide. In this role, you might architect a device certification service that automates hardware qualification by encoding the operational knowledge of what makes a device "production-ready," build vendor abstraction layers that normalize the behavior of vendor/OEM devices behind a single routing API, or design fleet-wide configuration automation that replaces ticket-based change workflows with self-service pipelines. You will own greenfield platform design on a team transforming from operations to product delivery, bringing the rare combination of production software engineering skill and deep systems operational awareness.
Key job responsibilities
- Architect and build a device certification service that automates hardware qualification, encoding operational expertise into programmatic validation pipelines that scale across device categories and vendors without manual testing workflows.
- Design and deliver the ADM vendor abstraction layer - a unified routing API that normalizes device management commands across MDM platforms (SOTI, Workspace ONE) and OEM-specific agent behavior, with MAD owning the routing logic.
- Build fleet automation tooling that replaces ticket-driven configuration changes, PCC deployment sequencing, and manual device lifecycle workflows with self-service pipelines and event-driven orchestration.
- Own the integration layer between MAD's services and OEM vendor SDKs, firmware update mechanisms, and device agent behavior - managing the complexity of Android OS fragmentation across different OEM/Vendors.
- Design device telemetry pipelines that ingest fleet-wide health signals - battery degradation curves, memory utilization patterns, application crash rates - and surface them through observability tooling that enables proactive fleet management.
- Establish engineering practices for the team including design doc standards, code review culture, testing strategies, and CI/CD patterns - driving the cultural shift from operational runbooks to software releases from a position of shared operational credibility.
A day in the life
Your mornings include standup, code reviews, and heads-down time building the abstraction layers that make vendor differences invisible to upstream consumers

Afternoons involve working sessions with partner teams to align on interface boundaries or investigating device behavior that only manifests on specific firmware versions. You'll occasionally join a certification lab session, connect with an OEM engineering team about a firmware quirk, or trace an issue from the fulfillment floor back to a specific agent configuration. On-call rotation is shared across the team.

About the team
The Mobility and Devices (MAD) team sits within OTS Network Dev and owns the device layer for Amazon's fulfillment technology stack - device certification, fleet-wide configuration management, and health monitoring for 800K+ mobile devices across 3,000+ sites.

We are in the middle of a deliberate shift from operations to product, building services where processes used to exist: automated validation replacing manual certification, self-service APIs replacing ticket-driven configuration changes, and proactive telemetry replacing reactive monitoring.
