Founding RF Engineer (Leading Architect)

SBT; Wilmington (MA); On-site; USD 150,000 - 230,000; Full time

Job summary

SBT is a confidential stealth startup focused on a new class of highly integrated, low-power semiconductor systems. We are seeking an experienced analog/RF IC designer with a track record in low-power wireless technologies such as BLE and related RF systems.

You will define the RF/analog architecture for an integrated wireless platform, design critical blocks (LNAs, mixers, PLLs, VCOs, amplifiers), and own the path from architecture through tape-out and silicon bring-up.

Qualifications

• Extensive experience designing analog/RF ICs with silicon tape-outs.
• Deep CMOS RF and analog circuit expertise.
• Strong grasp of low-power radio architectures for wireless.
• Experience designing LNAs, mixers, PLLs, VCOs, and amplifiers.

Responsibilities

• Define and develop RF/analog architecture for a wireless SoC or custom silicon.
• Design RF/analog circuits (LNAs, mixers, PLLs, VCOs, amplifiers, filters, biasing).
• Develop low-power RF architectures for BLE-like short-range wireless applications.
• Own designs from architecture to tape-out and silicon bring-up.
• Establish RFIC design methodology and verification infrastructure.

Job description

This confidential stealth startup company is building a new class of highly integrated, low-power semiconductor systems. The team is developing custom silicon that brings together advanced analog, RF, and digital technologies to enable differentiated wireless products.

The ideal candidate is fundamentally an analog/RF IC designer with strong experience developing low-power wireless technologies such as Bluetooth Low Energy (BLE), short-range radios, connectivity devices, or related RF systems.

Role

• Define and develop the overall RF and analog architecture for a highly integrated wireless SoC or custom silicon platform
• Design critical RF and analog circuits such as LNAs, mixers, oscillators, PLLs/frequency synthesizers, amplifiers, filters, biasing, and supporting analog circuitry
• Develop low-power RF architectures suitable for short-range and energy-constrained wireless applications, including technologies with characteristics similar to BLE and other low-power connectivity standards
• Own designs from architecture and schematic development through simulation, layout collaboration, verification, tape-out, and silicon bring-up
• Establish the company's RFIC design methodology, simulation environment, verification practices, and development infrastructure.

Qualifications

• Significant industry experience designing analog and RF integrated circuits, ideally with multiple successful silicon tape-outs
• Deep hands-on expertise in CMOS RF and analog circuit design
• Strong understanding of low-power radio architectures and wireless transceiver design
• Demonstrated experience designing several core RF blocks such as LNAs, mixers, PLLs, VCOs, frequency synthesizers, amplifiers, or related analog/RF circuitry
• Experience with wireless technologies such as BLE, Bluetooth, low-power connectivity, short-range wireless, IoT radios, or comparable RF systems
• Comfortable operating in an early-stage environment where engineers are expected to combine architecture ownership with hands-on implementation
• Experience building technology from an early stage, mentoring engineers, or working with external semiconductor partners is a plus
