Software Engineer

GCS Recruitment; Atlanta (GA); On-site; USD 140,000 - 210,000; Full time

Job summary

GCS Recruitment seeks an experienced senior software engineer to own platform modules for cabin network management and observability, delivering robust OTA pipelines and fleet telemetry.

You will lead architecture discussions, work with real devices on Linux, and collaborate across avionics, cloud, and embedded teams to ship secure, test-driven software. Strong autonomy and clear documentation are essential for success.

Qualifications

• 6+ years of professional software development experience.
• Experience with Linux-based development on real devices.
• Strong networking fundamentals: VLANs, routing, QoS, and troubleshooting.
• Experience building or operating OTA/firmware pipelines and device-to-cloud systems.

Responsibilities

• Design and implement core platform modules for cabin network management and observability.
• Build and maintain OTA software lifecycle pipeline with signing, staged rollout, and rollback.
• Develop telemetry and health-monitoring infrastructure for fleet monitoring.
• Integrate software across multiple cabin hardware platforms with portable HALs.
• Create and run unit, integration, and hardware-in-the-loop tests.
• Contribute to interface definitions and architecture decisions; perform design reviews.

Job description

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.
