About the Role

Senior Backend Engineer (Cloud Platform + Integrations + Subscription Systems)

As one of the founding engineers building Unbound Central, you will own the core backend architecture powering our next-generation, API-first satellite network platform. You will build and scale the systems behind multi-tenant subscription management, offer configuration, billing, fulfillment, device provisioning, and AIOps integrations.

This is a hands-on, ownership-heavy role that will shape the technical foundation of the product for years to come.

Responsibilities

Backend Architecture & Development

Design and implement a headless, API-first backend for Unbound Central.
Build multi-tenant services handling:
- Service catalog & offer configuration
- Pricing, discounting, and approval logic
- Quoting and order orchestration
- Subscription lifecycle engine (renewals, upsells, downgrades, cancellations)
- Billing & invoicing integration
- Provisioning, activation, and asset‑tracking workflows
Develop secure, scalable data models supporting customer, subscription, asset, and fulfillment domains.

Integrations

Integrate with:
- CRM & billing platforms
- SATCOM networks and modem APIs
- Deployment, logistics, and asset management systems
- AIOps engines for alerting and monitoring
Design robust integration patterns (webhooks, events, async workers, ETL pipelines).

Platform Engineering

Implement identity, roles/permissions, and access control models.
Build event-driven workflows for notifications, subscription changes, and fulfillment updates.
Own CI/CD pipelines, IaC, environment management, and deployment automation.

Reliability, Security & Observability

Build highly reliable services with 99.9%+ uptime goals.
Implement observability: logs, distributed tracing, metrics.
Apply strong security practices (encryption, secrets, tenant isolation).

Collaboration

Define API contracts and service boundaries with the full‑stack engineer.
Work closely with product leadership to translate the PRD into scalable backend systems.
Establish coding standards, architectural guidelines, and development best practices.
