Note: The job is a remote job and is open to candidates in USA. Vervint is hiring a Senior Cloud Engineer for its backend platform team to own over-the-air (OTA) and firmware management. The role focuses on designing and operating firmware publishing, device eligibility, progressive rollouts, delivery, observability, APIs, and infrastructure across Go and AWS.
Responsibilities
- 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
Skills
- 6+ years building production backend services in the cloud, with strong hands-on Go — or deep experience in another statically typed language and real appetite for writing Go
- Deep AWS experience across serverless and container services — Lambda, ECS and Fargate, API Gateway, DynamoDB, S3 — and the judgment to choose between them
- Direct experience with OTA, firmware distribution, or fleet update systems — or another high-stakes rollout system where a mistake reaches users you cannot easily reach back
- Strong data modeling instincts, including DynamoDB design for versioned, immutable, and precedence-based data
- Real understanding of device constraints: intermittent connectivity, limited storage, resumable downloads, and partial failure
- Versioning discipline — semantic versioning, compatibility rules, and rollback thinking done before the rollout rather than during it
- Infrastructure as code, CDK preferred, plus IAM, KMS, artifact integrity, and least-privilege access as part of your normal work
- A track record on contract engagements: you ramp up fast, work inside existing conventions, and scope your own work — plus a passion for connected consumer products and the curiosity to thrive alongside a strong engineering team
- Connected device or IoT backends: MQTT and IoT Core, device state, provisioning, and manufacturing flows
- Firmware signing, secure boot, or artifact and supply-chain integrity practices
- AWS IoT Jobs, IoT Device Management, or comparable fleet orchestration tooling
- Consumer hardware at scale — large fleets, multiple regions, and long product lifetimes with old firmware still in the field
- Observability and on-call practice (Prometheus, Loki, OpenTelemetry, alarms, runbooks), and using AI-assisted development tools where their output can be verified
Benefits
- Remote work
