Sci Tec is seeking a Hardware Integration Engineer to support the Ground‑Based Radar Digitization (GBRD) modernization program. In this role, you will focus on the integration of modern radar front‑end hardware—including digitizers, transceivers, timing/synchronization components, and associated control interfaces—into a unified digital backend architecture. You will work across radar hardware teams, RF specialists, systems engineers, and software‑processing teams to ensure that modern front‑end hardware integrates seamlessly with mission‑critical backend processing.

• Front‑End Hardware Integration
  • Integrate modern radar front‑end subsystems (digitizers, transceivers, control electronics, digital transceiver components) with digitized radar back‑end signal‑processing chains.
  • Ensure element‑level digitization produces validated, high‑fidelity I/Q data streams suitable for backend processing.
  • Collaborate with RF engineers to verify operating characteristics and compatibility with each radar's unique antenna systems.
• Interface Definition & System Alignment
  • Develop and maintain interface specifications between front‑end hardware and the modernized digital backend.
  • Ensure alignment with MOSA principles and common GBRD architectural standards.
  • Work closely with systems engineers to ensure hardware‑to‑software interactions meet timing, throughput, and synchronization constraints.
• Integration Testing & Troubleshooting
  • Support integration in lab environments, performing functional tests, data‑validation checks, and end‑to‑end link testing.
  • Diagnose and resolve issues related to hardware configuration, signal integrity, timing alignment, data‑path reliability, and high‑bandwidth throughput.
  • Work with backend RSP/RMP teams to ensure hardware‑driven measurements and transmission instructions flow correctly.
• Requirements, Configuration Control & Documentation
  • Contribute to requirements decomposition for hardware integration, defining performance, interface, and environmental needs.
  • Maintain configuration control of hardware integration artifacts, diagrams, ICDs, test plans, and verification results.
  • Support technical reviews (SRR, PDR, CDR, TRR) with clear hardware‑integration inputs.
• Cross‑Team Collaboration
  • Coordinate with RF engineers, systems engineers, software‑processing teams, mission‑processing teams, and cybersecurity personnel to ensure cohesive system behavior.
  • Ensure front‑end hardware integration supports mission‑focused outcomes in alignment with the GBRD common digital baseline.
  • Other duties as assigned

• Bachelor's or Master's in Electrical Engineering, Systems Engineering, Physics, or related field.
• 8+ years of experience integrating hardware for radar, RF systems, high‑bandwidth sensor systems, or real‑time mission systems.
• Experience with digitizers, transceivers, RF electronics, timing/synchronization hardware, or data‑acquisition equipment.
• Understanding of signal‑integrity concepts, analog‑to‑digital conversion, and high‑bandwidth data flows.
• Familiarity with lab integration environments (SIL/DSIL) and hardware‑in‑the‑loop testing.
• Ability to read and produce interface control documents, wiring diagrams, and system‑integration artifacts.
• Experience collaborating across hardware, software, RF, and…
