Job description

Job Summary 
WGS Systems, a leading innovator in communications and defense industries, is looking to expand our technical team. We are seeking an early-career multidisciplinary engineer to support product development across electronics design, hardware integration, and software development. This hybrid role offers unique exposure to both hardware and software disciplines, ideal for someone who enjoys variety and wants to build broad systems engineering capabilities in the defense/aerospace sector. 
You'll contribute approximately 50% of your time to electronics engineering tasks (circuit design, PCB layout, hardware debugging, sensor integration) and 50% to software development (embedded systems, firmware development, data acquisition, and analytics infrastructure support). You'll work at the intersection of sensor hardware and data science, ensuring our RF and electronic systems function reliably while collecting high-quality data that integrates seamlessly with our analytics platform. 
As our product portfolio grows, this role will evolve with your interests and company needs. This position is perfect for someone who doesn't want to be pigeonholed into a single discipline and thrives in a fast-paced, hands-on engineering environment where you'll see your work go from concept to fielded system.

  • Design and develop analog and digital circuits, power distribution systems, and signal conditioning for RF sensor platforms 
  • Create PCB layouts and schematics using tools like Altium Designer; manage board bring-up and testing 
  • Integrate commercial RF components, cameras, processors, and sensors into custom electronics assemblies 
  • Debug hardware issues using oscilloscopes, logic analyzers, spectrum analyzers, and other test equipment 
  • Conduct EMI/EMC testing and design for compliance with MIL-STD-461 and other electromagnetic compatibility standards 
  • Support thermal management design for electronics; coordinate with mechanical team on cooling solutions and packaging 
  • Create and maintain electrical schematics, BOMs, wiring diagrams, and technical documentation per AS9100 standards 
  • Work with contract manufacturers and PCB fabrication houses to transition designs to production 
Software Development (50%) 
  • Develop embedded firmware for microcontrollers and embedded Linux systems controlling RF sensors and data acquisition (C/C++, Python) 
  • Write device drivers and hardware abstraction layers for custom electronics and sensor interfaces 
  • Build data pipelines and ETL processes to ingest sensor data into analytics infrastructure; support integration with commercial datasets 
  • Develop preprocessing and feature extraction algorithms for raw sensor data to support ML model development 
  • Create APIs and communication protocols between embedded systems and cloud analytics platforms; ensure data quality and formatting standards 
  • Implement real-time data processing and streaming for low-latency sensor applications 
  • Develop test automation and hardware-in-the-loop (HIL) testing frameworks for electronics validation 
  • Contribute to version control practices (Git), continuous integration, and documentation for firmware deliverables 
Cross Functional Collaboration: 
  • Work closely with RF engineers, data scientists, and senior systems engineers to integrate electronics and software subsystems 
  • Partner with data science team to ensure sensor data collection meets analytics requirements; implement data quality checks and validation 
  • Support development of data infrastructure for model training, including data storage, versioning, and retrieval systems 
  • Collaborate with mechanical engineers on enclosure design, thermal management, and electromagnetic shielding requirements 
  • Support Factory Acceptance Testing (FAT), customer demonstrations, and field testing activities 
  • Participate in design reviews, failure analysis, root cause investigations, and continuous product improvement initiatives Required Qualifications
