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.

Job Title: Senior FPGA Design Engineer
About The Program:
Our client is building one of the world's largest low-Earth-orbit satellite constellations, delivering broadband internet from space. The hardware team behind it designs the electronics that drive the satellites' phased-array antennas: meter-scale, 20+ layer boards carrying custom silicon connected by ~25 Gbps high-speed serial links. Boards are designed, brought up, and validated in-house - engineers on this team see their own work running on real flight hardware.
The Role:
You will own programmable logic in the phased-array signal chain on AMD/Xilinx Versal devices - designing and integrating high-rate datapaths between the board's custom silicon, configuring and debugging multi-gigabit transceiver links, and bringing your logic up on brand-new boards in the lab alongside the electrical engineering team. This is a hands-on design-and-hardware seat: your deliverables run on real boards headed for orbit, not in a simulation environment.
What You'll Do:
Design, integrate, and debug RTL for high-speed datapaths on Versal ACAP devices.
Configure and bring up GTY transceivers - link tuning, eye scans, and debug of live 25 Gbps-class serial links.
Configure MRMAC hard IP for multi-rate Ethernet (25G / 50G / 100G) and validate high-rate traffic end to end.
Build and maintain embedded Linux (PetaLinux/Yocto) images, device trees, and drivers for the Versal processing system.
Bring up your logic on first-article boards in the lab - JTAG, ILA, and bench instrumentation - working shoulder to shoulder with board design engineers.
Build debug and monitoring hooks used across design validation campaigns.
Required Experience:
25G/50G/100G - Very high speed interfaces - hands-on design and bring-up at 25G / 50G / 100G.
MRMAC & GTY - Direct experience configuring MRMAC and GTY blocks - transceiver setup, tuning, and link debug on real hardware.
Versal ACAP - Working knowledge of the Versal ACAP architecture and toolchain (Vivado/Vitis).
Embedded Linux - Building images, device trees, and drivers for ARM-based FPGA processing systems (PetaLinux/Yocto).
8+ years of RTL design (Verilog/SystemVerilog/VHDL) shipped in real products, with timing closure on modern devices and genuine board bring-up experience.
Nice To Have:
JESD204, Aurora, or other high-speed converter/serial protocols.
Aerospace or high-reliability design exposure (DO-254, MIL-STD, radiation-aware design).
Prior satellite, SATCOM, radar, or high-speed networking product work.
Experience prototyping functions ahead of custom ASIC development.
