Distinguished Engineer, Analog ASIC

Company Description

Butterfly Network’s mission is to democratize healthcare by enabling universal access to superior medical imaging. We reinvented ultrasound technology by creating the world’s first handheld, single-probe whole-body ultrasound system: the Butterfly iQ. This innovative technology reduces the cost of the traditional ultrasound system by miniaturizing it onto a single semiconductor silicon chip. Butterfly harnesses the power of AI and cloud computing to deliver advanced ultrasound imaging that is easy to use and purpose-built for the digital era.

The Butterfly iQ and iQ+ devices have received FDA clearance and CE Mark certification and are used by hospitals and clinics around the world. Joining Butterfly Network is an opportunity to help reimagine healthcare delivery through technology. You’ll be part of a mission-driven team focused on building products that expand access to medical imaging and make a meaningful impact on the lives of millions—including those closest to you.

We are seeking a Principal or Distinguished level Analog & Mixed-Signal IC Designer to provide technical leadership and hands‑on ownership for advanced ultrasound and sensing integrated circuits. This role focuses on high‑voltage analog front ends, large‑channel‑count arrays, and ultra‑high‑bandwidth data paths (hundreds of Gbps aggregate scale) that enable real‑time imaging and AI‑assisted acquisition in compact form factors. This is a system‑level analog leadership role, not a narrow block‑design position.

Key responsibilities include:

System‑Level Analog Architecture, High‑Voltage & Front‑End Circuit Design, High‑Bandwidth Data Interfaces.

• Analog front ends meet aggressive bandwidth, noise, and reliability targets.
• Designs scale cleanly across product generations and use cases.
• System‑level performance (image quality, frame rate, power) is enabled—not limited—by analog architecture.
• The analog team operates with rigor, clarity, and long‑term architectural discipline.

Baseline skills/experiences/attributes:

• 15+ years of industry experience in analog or mixed‑signal IC design.
• MS or PhD in Electrical Engineering (or equivalent silicon track record).
• Deep hands‑on experience with high‑voltage analog design, low‑noise signal acquisition, and large‑channel‑count mixed‑signal systems.
• Multiple successful production silicon tape‑outs with bring‑up responsibility.
• Strong command of noise, linearity, dynamic range, EM/IR, ESD, latch‑up, reliability, DFM.
• Ability to operate effectively at both architecture and circuit‑implementation levels.

Ideally, you also have these skills/experiences/attributes:

• Ultrasound, medical imaging, or other sensing front ends.
• CMUT, PMUT, or MEMS‑based transducer systems.
• Systems requiring real‑time imaging and/or 3D data acquisition.
• High‑bandwidth, power‑constrained designs.
• Experience in regulated or safety‑critical products.

• Efficient & Speedy – you get work done in a fraction of the time as industry peers.
• Intellectually Curious – you are thoughtful & inquisitive; people enjoy working with you because they learn from you.
• Mission‑Driven & Committed – you are passionate about the company's purpose and are immensely productive.
• Team Oriented – you celebrate and take joy in the success of others on the team.

Butterfly offers a hybrid work model for most positions, with team members spending two or more days a week in the office. While flexibility is key, we value in‑person connections that spark creativity and teamwork. Our offices are designed for collaboration, with comfortable work spaces, stocked kitchens, and opportunities to connect with peers.

For this role, location will depend on candidate qualifications and experience. This role may be based out of one of our U.S. offices, including:

• SF Bay Area
• Burlington, MA

• Comprehensive health insurance, encompassing dental and vision coverage, is provided to all our employees. As a health‑tech company, we prioritize the well‑being of our teams. We also contribute to Health Savings Account (HSA) accounts for all enrolled…
