Job Description

We're looking for a hands-on RF Systems Integration Engineer to take ownership of the physical build and validation of advanced mobile communication systems. This role is focused on real-world integration—rack builds, RF interconnects, power systems, and performance validation—not purely design or simulation work. If your experience is grounded in lab, bench, or field work rather than purely theoretical design, this will be a strong fit.

Responsibilities

System Integration & Assembly

  • Lead mechanical and electrical integration of RF modules, power distribution systems, and thermal hardware into ruggedized rack systems
  • Build and wire complete systems to production-quality standards

RF Interconnects

  • Design and fabricate RF cable assemblies using SMA, N-Type, and similar connectors
  • Ensure low-loss signal paths with proper torque application and handling of semi-rigid and low-loss coax

Power Systems & Safety

  • Configure multi-rail DC power distribution systems
  • Implement grounding, protection, and safety best practices for sensitive RF equipment

System Validation & Testing

  • Perform system bring-up (smoke tests) and end-to-end validation
  • Measure and optimize VSWR, insertion loss, and overall RF performance
  • Conduct thermal and stress testing under operational loads

Data & Networking

  • Configure high-speed interfaces (10GbE, SFP+, DAC/fiber)
  • Optimize data throughput between radios and compute systems
  • Use Linux command-line tools for system configuration and diagnostics

Documentation

  • Maintain detailed build records, wiring diagrams, and test reports
  • Support repeatable, production-ready integration processes

Qualifications

  • 3–5+ years of hands-on experience in RF hardware integration (telecom, defence, aerospace, or industrial systems)
  • Strong practical skills in: Soldering and industrial wiring, RF connectors (SMA, N-Type, etc.)
  • Proven experience with RF test equipment: Spectrum analyzers, Vector Network Analyzers (VNA), and Power meters
  • Working knowledge of: 10GbE networking and SFP+ interfaces, Linux command-line tools, and has Experience working with high-density electronic systems and thermal constraints
  • Strong troubleshooting skills with a methodical, hands-on approach to diagnosing hardware, RF, and system-level issues
  • High attention to detail with the ability to produce clean, production-quality builds and maintain proper documentation
  • Familiarity with industry standards and best practices (e.g., IPC standards, RF handling practices, safety protocols) is an advantage
  • Experience supporting field deployment, installation, or commissioning of RF systems is a strong advantage
  • Diploma or Bachelor's degree in Electrical Engineering, Telecommunications, RF Engineering, or related field (practical experience is prioritized over purely academic background)
  • Professional certifications (e.g., RF certifications, networking certifications, or safety certifications) are a plus

Note: This role is not suitable for fresh graduates. We are specifically seeking candidates with proven, hands-on industry experience.
