Job summary

Calico Teknoloji is seeking a hands-on RF System Engineer who bridges RF system engineering with ground/industrial electrical systems. You will work with multi-disciplinary teams to specify, integrate, test, and document complete end-to-end systems—from RF front ends to power, control, and networking.

You will contribute across the lifecycle: architecture, component selection, link budgets, grounding strategies, and rugged interconnects, while ensuring thorough documentation and practical field

Qualifications

• Bachelor’s degree in Electrical Engineering.
• 3+ years of relevant industry experience in RF/electrical system integration or adjacent hardware.
• Strong fundamentals in electronics, system integration, and first-principles problem solving.
• Hands-on capability: building, wiring, reworking, and debugging real hardware in lab/field.
• Solid understanding of RF system concepts and practical component behavior.
• Ability to derive and defend link budgets, including geometry and LoS constraints.
• Familiarity with RF components, connectors, cables, and measurement considerations.
• Experience with power wiring and harnessing fundamentals, protection, and safe layout practices.
• Working knowledge of Modbus, CAN, I2C, SPI, UART, RS-232/RS-485/RS-422.
• Familiarity with Ethernet basics and physical integration.
• Ability to read and produce schematics, wiring diagrams, and interface documentation.
• Python for automation, test scripting, data analysis, or light embedded tasks.
• Proficiency with lab test equipment: VNA and oscilloscope; familiarity with generators, meters, and power supplies.
• Strong communication and documentation habits.

Responsibilities

• Architect, specify, and integrate electrical and RF subsystems into a cohesive system.
• Drive RF system engineering using COTS components; define requirements and coordinate procurement.
• Develop and maintain link budgets considering LoS, geometry, and antenna patterns.
• Define RF signal chains and interconnections; employ attenuators, filters, couplers, LNAs/LNBs, mixers, and switches.
• Maintain knowledge of antenna families and their effects on coverage and margin.
• Lead ground/field electrical design: AWG sizing, derating, protection, safety, and lightning concepts.
• Design and review grounding/bonding for DC and RF systems; minimize noise paths.
• Own industrial control and digital communications integration (Modbus, CAN, I2C, SPI, UART, RS-232/RS-485/RS-422).
• Support Ethernet/networked system integration at a practical level.
• Select rugged interconnects (automotive/military) and ensure proper sealing and strain relief.
• Apply MIL-STD-810 concepts to wiring, connectors, enclosures, and components.
• Build bench setups and hardware-in-the-loop rigs; prototype, integrate, assemble, and troubleshoot.
• Validate and troubleshoot with lab instrumentation (VNA, oscilloscope, signal generators, meters).
• Create and maintain system documentation (block diagrams, wiring diagrams, ICD/IDD interfaces, test procedures).
• Provide engineering support to technicians and cross-functional teams; communicate across engineering disciplines.
