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.GCS is acting as an Employment Business in relation to this vacancy.
