Job Title: RF Architect

Location: Bengaluru | Job Type: Full-Time | Experience Level: 10-15yrs

Job Summary: We are seeking a highly motivated and skilled RF Architect to join our engineering team. The ideal candidate will be responsible for design, simulation, implementation, and testing of RF circuits and systems for various applications. This role requires strong technical expertise in RF design and microwave design principles with a flair for root causing issues, possess design ideas to optimize solution cost, hands-on lab experience, and a collaborative approach to problem-solving.

Key Responsibilities:

• Design and develop RF systems involving cellular technologies 2G, 3G, LTE, 5G and wireless communication technologies Wi-Fi, BT, GNSS, mmWave, NR etc.

• Design RF sub-systems, including transceivers, RFICs, Power Amplifiers, LNAs, filters, couplers, power dividers and antennas.
• Meet product BOM cost targets by way of design optimization without compromising RF performance.

• Apply strong knowledge of RF to analyse system level performance and solve RF related issues quickly.
• Conduct detailed design reviews for RF section and drive performance and cost improvements on a regular basis.
• Guide engineers to validate designs through prototyping, testing, and debugging using lab equipment (VNA, spectrum analysers, communication analyser, Signal generator, Oscilloscope etc.).
• Responsible for design and verification of Transmitter chain parameters like ACLR, Modulation Analysis (EVM, CCDF, Frequency Error), occupied bandwidth, Transmitter unwanted Emissions, Intermodulation.
• Responsible for design and verification of Receiver parameters like Gain, Noise Figure, Receiver dynamic Range, Blocking (In-band, Narrow-band, Out of band.
• Provide guidance in protocol conformance testing (PCT) and Radio conformance testing (RCT).
• Calibrate and optimize wireless interface for performance and quality.
• Work with cross-functional teams to ensure design compatibility and system integration.
• Generate technical documentation, including design reports, test plans, and datasheets.
• Support product certification processes and ensure compliance with industry standards (FCC, CE, etc.).

Required Skills & Qualifications:

• Bachelor’s or Master’s degree in Electronics & Communication engineering, Telecommunication engineering or a related field.
• 10-15 years of hands-on experience in RF/Microwave circuit design and development with strong technical leadership skills.

• In-depth knowledge of cellular radio standards (GSM, UMTS, LTE, NR), regulatory requirements, and carrier requirements.

• Strong in RF design concepts with ability to convert concept to product with design ideas to meet cost targets within PCB real estate requirements.
• Ability to analyse RF issues and solve problems in a timely manner with root cause analysis.
• Ability to generate test plans to validate RF performance to ensure all RF parameters are fully validated.
• Capability to decide on critical RF performance differentiating parameters for the product and build expertise within the team.

Preferred Qualifications:

• In-depth knowledge with RF architecture and requirements.
• Experience in design of RF systems particularly cellular systems, wireless technologies and knowledge of antenna design and optimization.
• Strong analytical and interpersonal skills with an ability to thrive in a multi-functional environment.
• Knowledge of Product regulatory & CERT requirements for RF solutions.
• Strong problem solving skills.
• Experience in automotive domain desirable.
