We are seeking a Backend MDM Engineer to design and scale our next-generation Mobile Device Management (MDM) infrastructure. In this role, you will be responsible for the core server-side services that enroll, configure, secure, and monitor enterprise Android and iOS/macOS fleets.

Your primary focus will involve engineering dual-track MDM management pipelines: leveraging Google's Android Management API (AMAPI) for Android Enterprise devices, and architecting an Apple MDM pipeline powered by NanoMDM for iOS/macOS devices. You will work with security protocols, device enrollment flows (Zero-touch, Knox Mobile Enrollment, Apple Automated Device Enrollment / DEP), Public Key Infrastructure (PKI), and high-throughput real-time command dispatching.

Key Responsibilities

Android Management (AMAPI)

  • Architect and maintain server-side integrations with Android Management API (AMAPI) to provision policies, applications, network profiles, and compliance rules.
  • Handle Google Cloud Pub/Sub webhooks to ingest real-time device states, enrollment notifications, non-compliance alerts, and command delivery acknowledgments.
  • Implement zero-touch enrollment and QR-code-based provisioning workflows for dedicated, corporate-owned, and work-profile deployment scenarios.

Apple Management (NanoMDM / Apple MDM Protocol)

  • Deploy, scale, and integrate NanoMDM as our core Apple MDM protocol gateway.
  • Maintain Apple Push Notification service (APNs) integration for low-latency command queueing and delivery to Apple devices.
  • Handle Apple MDM command sequences (e.g., install profiles, device wipe, query device information, manage restrictions, install enterprise apps).
  • Integrate Apple Automated Device Enrollment (ADE / DEP) and Volume Purchase Program (VPP) via Apple Business Manager / Apple School Manager APIs.
  • Prepare the platform for Apple's Declarative Device Management (DDM) migration.

Core Backend & Infrastructure

  • Design, implement, and maintain scalable APIs using Node.js (TypeScript) with strong concurrency patterns, clean service layers, and schema validation.
  • Build and manage PKI and certificate infrastructure: SCEP (Simple Certificate Enrollment Protocol), EST, and mTLS certificate verification for device authentication.
  • Design robust PostgreSQL schemas for device inventory, historical telemetry, policy diffing, and audit logging.
  • Monitor backend availability, APNs throughput, Pub/Sub message queues, and error rates using tools like Prometheus, Grafana, and OpenTelemetry.

Qualifications & Skills

Must-Have Requirements

  • Professional Experience: 3+ years of production experience in backend software engineering with Node.js (preferably with TypeScript).

MDM Domain Expertise:

  • Demonstrated experience working with Android Management API (AMAPI) or Android Enterprise SDKs.
  • Practical understanding of the Apple MDM Protocol (Check-in, Command-and-Report cycle, APNs push mechanics, and Configuration Profiles).

Security & PKI:

  • Strong working knowledge of TLS, mTLS, SCEP/EST protocols, and X.509 certificate lifecycles (issuance, renewal, and revocation).

Data & Messaging:

  • Proficiency in relational database design (PostgreSQL) and caching/queueing systems (Redis, RabbitMQ, Kafka, or Google Cloud Pub/Sub).
  • API Design & Cloud Infrastructure:
  • Experience with Docker, Kubernetes, and cloud platforms (GCP or AWS).
  • Familiarity with consuming high-throughput webhook streams and implementing idempotent processing.

Preferred Qualifications

  • Working knowledge or willingness to learn Go (Golang) to debug, customize, or contribute directly to the NanoMDM open-source engine.
  • Hands-on experience with Apple Automated Device Enrollment (ADE/DEP) and Apps and Books (VPP) API handshakes.
  • Experience with Apple Declarative Device Management (DDM) state-channel updates.
  • Knowledge of Knox Mobile Enrollment (KME) and Android custom DPC extensions.
