About The Guild Ethereal Exploration Guild (The Guild) was founded in 2022. It is building Razor Crest Mk-1 (RCM1), the world’s first fully reusable medium-lift launch vehicle, where both stages fly back and fly again. The team brings more than 350 years of collective space-industry experience and a combined flight heritage of over 75 PSLV and GSLV launches. Most vehicle-critical work is done in-house, including:
• Propulsion: The Guild built India’s first reusable rocket engine. It is also developing a patented full-flow staged-combustion feed cycle, which makes it possible to recover and reuse the upper stage, not just the booster.
• Avionics: the flight computer, engine control units, power systems and GNC are designed in-house.
• Infrastructure: The Guild is building The Anchorage, a 149-acre site at Space City, Andhra Pradesh, about an hour from SDSC SHAR. Engine testing, stage qualification, manufacturing and vehicle integration will all happen there. Role Summary: As an Avionics Hardware Engineer, you will take end-to-end ownership of flight and ground avionics hardware for a fully-reusable, two-stage-to-orbit launch vehicle
- from system requirements and architecture to qualified, production-ready hardware. In a startup setting, you will work across FPGA-based digital systems, high-speed and mixed-signal electronics, PCB design, and RF and antenna subsystems, building robust, fault-tolerant hardware for demanding aerospace environments.

- Support hardware-software integration with embedded software and FPGA teams: interfaces, timing, data paths, and boot sequences
- Support engine and vehicle ground tests, with real-time troubleshooting, failure analysis, and post-test assessment
- Drive root-cause analysis of intermittent faults, SI issues, RF anomalies, and power failures through verified resolution 6. Documentation, Configuration Control & Cross-Functional Impact
- Maintain schematics, PCB layouts, BOMs, electrical ICDs, specifications, test procedures, and qualification reports
- Maintain configuration control, design traceability, and engineering change processes throughout the lifecycle
- Work with software, FPGA, GNC, mechanical, propulsion, systems,



and test teams to resolve vehicle-level integration issues
- Contribute to reusable, scalable avionics architectures with emphasis on testability, manufacturability, and modularity Educational
