Sr. Engineer - Hardware/RF Applications

Responsibilities:

• Hardware Design & Evaluation (30%): o Debug and characterize LoRa-based Evaluation Kits, Reference Designs, Demonstrations, and Proof-of-Concept hardware at the bench: RF performance, power consumption, signal integrity, and power management behavior. o Validate and document design performance against specifications using RF and electronic test equipment.
• Customer & Internal Technical Support (30%): o Provide hands-on technical support to Semtech Field Application Engineers, Sales, and Business Development teams. o Work directly with customers to analyze and resolve hardware and RF design issues; conduct design reviews and recommend corrective actions.
• Test Tools & Automation (30%): o Develop and maintain evaluation and production test setups for conducted RF and analog measurements, including scripted automation using Python.
• Technical Documentation (10%): Produce high-quality technical documentation including measurement reports, application notes, and design guides to promote Semtech products and accelerate customer design-in. Minimum Qualifications: B.E./B.Tech or M.E./M.Tech (or equivalent) in Electronics & Communication, Electrical & Electronics, or a related field; RF/microwave specialization welcome. 7+ years of proven hands-on experience with RF measurement instruments and techniques: spectrum analyzer, RF signal generator, vector network analyzer. Experience with embedded electronics and hardware debug: hardware interfaces (UART, SPI, I²C), oscilloscope, logic analyzer, voltage/current measurement. Understanding of power management design: LDO and DC-DC converter selection and layout, current consumption profiling, battery management. Familiarity with Python programming for test bench automation and measurement scripting is a strong advantage. Solid experience in RF PCB design techniques for sub-GHz and/or 2.4 GHz bands: impedance matching, transmission lines, antenna interfacing, shielding and EMC layout practices is a plus. Full working proficiency in English. Desired Qualifications Proficiency with hardware design, covering the full design cycle: schematic capture, component selection, PCB layout (Altium Designer or equivalent), bring-up, and functional validation. Knowledge of radio modulations, as well as RF propagation, link budget, interference, and coexistence challenges. RF pre-compliance awareness (ETSI/FCC) would fit the role Experience with embedded firmware and wireless communication protocols (LoRa, LoRaWAN, FSK, BLE) is a definite plus. Rigorous, creative, and solution-oriented, with a structured, practical approach to problem solving. Able to manage multiple tasks and learn new technologies in a fast-evolving environment Good communication skills, ability to work as a multi-site team partner across time zones. #LI-Onsite
