Senior Software Engineer *

In-Flight Connectivity Platform - LEO Satellite Broadband Program

Redmond, WA (preferred) or San Diego, CA

About the Program

Amazon Leo is Amazon's low Earth orbit (LEO) satellite broadband network - one of the largest constellations ever built - and it is bringing gigabit-speed internet to commercial aviation. Major airlines have already signed on, with fleet-wide rollouts on the roadmap.

You would join the aviation platform team: the group building the software that runs aboard the aircraft, managing cabin Wi-Fi networks, satellite connectivity, over-the-air software updates, and operational services for passengers, crew, and airlines simultaneously. The program is early-stage - the software you build now will operate across a growing commercial fleet for years.

The Role

This is a hands-on senior engineering role at the platform/middleware layer. The high-level architecture is in place - your job is to build, integrate, and ship against it. You will work in a team that blends avionics, enterprise networking, cloud, and embedded backgrounds, with a dedicated security engineering team supporting the platform. Modern AI-assisted development tooling is used extensively.

What you'll do:

  • Design and implement core platform modules - cabin network management (VLAN-based traffic segmentation and prioritization across passenger, crew, and airline operational services), connectivity monitoring, and observability.
  • Build and maintain the over-the-air (OTA) software lifecycle pipeline: cryptographically validated updates, staged activation, automatic rollback, and version reporting to ground-side fleet systems.
  • Develop telemetry and health-monitoring infrastructure, including the device-to-cloud data pipeline for fleet monitoring.
  • Integrate software across multiple cabin hardware platforms, maintaining hardware abstraction layers for portability.
  • Build and execute unit, integration, requirements-based, and hardware-in-the-loop tests.
  • Contribute to interface definitions and architecture decision records, and raise the bar through code reviews and design feedback.

What We're Looking For

Required:

  • 6+ years of professional software development experience, with several years leading design or architecture of production systems.
  • Strong Linux-based software development on real devices - C/C++ and/or Python.
  • Solid networking fundamentals: VLANs, routing, QoS / traffic prioritization, and network troubleshooting.
  • Experience with device-to-cloud systems: telemetry, health monitoring, or fleet/device management.
  • Experience building or operating software update pipelines (OTA/firmware: signing, staged rollout, rollback).
  • Containers (Docker; Kubernetes a plus) and modern CI/testing practices.
  • Comfort with ambiguity and autonomy - an early-stage program where strong engineering judgment and clear documentation matter as much as implementation skill.

Nice to have:

  • Background in in-flight connectivity, satellite communications, avionics, or other safety-adjacent embedded domains.
  • Familiarity with DO-178C software lifecycle (certification itself not required) or avionics interfaces such as ARINC 429.
  • Security engineering exposure: cryptography, secure boot, threat modeling, identity and access controls.
  • Experience with carrier-grade CPE/gateway software (e.g., RDK, OpenWrt, prpl) - this maps directly to the work.

Eligibility & Location

  • Work authorization: due to applicable U.S. export control regulations, candidates must be a U.S. citizen or national, U.S. lawful permanent resident (green card holder), or lawfully admitted refugee or granted asylum.
  • Location: on-site - Redmond, WA preferred, or San Diego, CA. Relocation candidates welcome.
  • Education: BS/MS in Computer Science, Electrical Engineering, or a related field, or equivalent practical experience.

Why This Role

  • Ground-floor engineering on a high-visibility program most engineers never get near - software that will fly on commercial aircraft worldwide.
  • Your decisions on architecture, interfaces, and implementation shape the platform for years of production operation.

A well-resourced, fast-moving team with extensive knowledge-sharing across avionics, networking, and cloud disciplines.
