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.
