Senior Cloud Engineer (Contract)

About this role

Senior Cloud Engineer | Remote | 4-month contract

Vervint is hiring a Senior Cloud Engineer to own OTA and firmware management for our backend platform team. This is a hands-on, contract engineering role: you'll own the cloud side of firmware publishing, device eligibility, and rollout delivery end to end — how firmware is published, which devices are eligible, how rollouts progress, and how we confirm an update actually landed — working in Go and AWS and making the architectural calls yourself.

What You'll Do:

• Work alongside architects to implement the firmware release model — hardware families, immutable bundles, channels, and per-device assignment — and the resolution rules that decide what a given device should be running.
• Run progressive rollouts safely: staged percentages, version pins and floors, pause and rollback, and eligibility rules that keep the wrong firmware off the wrong hardware.
• Own artifact publishing and delivery — checksummed packages in S3, expiring download URLs, and delivery that holds up on constrained devices and poor home networks.
• Build the reporting side so a rollout is observable while it's happening: update status from devices, success and failure rates, and the devices that are quietly stuck.
• Design the APIs and admin tooling that firmware, QA, and support teams use to publish builds, target test fleets, and unblock an individual device.
• Partner with firmware and manufacturing on version schemes, install policies, and what devices are expected to be running when they leave the factory.
• Treat safety as a design constraint: authorization on destructive operations, audit trails, and guardrails that make a catastrophic rollout hard to trigger by accident.
• Define your infrastructure as code across environments, and keep OTA alarmed, observable, and covered by the runbooks an on-call engineer needs at two in the morning.

What You'll Bring:

• 6+ years building production backend services in the cloud, with st...
