Software Engineer
gcs recruitmentKirkland (WA)
About the role
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 ForRequired: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.
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
