Test Engineer II

About Us

iota Biosciences, a wholly owned subsidiary of Astellas Pharma US, is advancing a new class of bioelectronic medicines through the development of fully implantable Class III medical devices. Our proprietary technologies open therapeutic and diagnostic possibilities not previously accessible to clinicians.

Together with Astellas, we are committed to patient-centric design, scientific and engineering excellence, and cross-functional teamwork. These principles guide us in bringing transformative, first-of-its-kind technologies into the clinic and closer to patient.

What you’ll Do:

We’re looking for a Senior Electrical Engineer who wants to build deeply technical, first-of-their-kind medical systems.

You’ll own critical parts of our implantable and external hardware systems, from architecture through prototyping to production. This is a hands-on role for someone who thrives in ambiguity, enjoys moving between bench work and system design, and wants their engineering decisions to directly shape patient outcomes.

What We’re Looking For

• Architect and design low-power, miniaturized electrical systems for implantable and wearable medical devices

• Lead schematic design, component selection, simulation, and PCB layout for complex mixed-signal systems

• Develop and debug analog/digital systems integrating MCUs and FPGAs

• Prototype early-stage hardware and rapidly iterate through testing and validation

• Bring up new boards from scratch and drive root-cause debugging using lab instrumentation

• Collaborate closely with firmware, mechanical, manufacturing, and systems teams to deliver fully integrated products

• Partner with manufacturing and process development to transition designs into production

• Contribute to system-level decisions that define product performance, power budgets, communication architecture, and long-term scalability

What You’ll Bring

• B.S. in electrical engineering or related technical field, with 3+ years of experience designing low-power, small form-factor electrical systems

• OR M.S. in electrical engineering or related technical field, with 3+ years of experience designing low-power, small form factor electrical systems

• Have built real hardware end-to-end — from concept to bring-up to validation

• Are deeply comfortable debugging at the bench with oscilloscopes, logic analyzers, and signal generators

• Have experience with:

  • Sensor front-ends and low-power ADCs

  • DC-DC converters and power management systems

  • Li-ion charging and battery systems

  • Wireless communication (BLE, WiFi, Zigbee, or similar)

  • MCUs and embedded systems

  • Common protocols (SPI, I2C, UART, etc.)

• Have full PCB ownership experience: schematic capture, simulation (e.g., LTspice/PSpice), layout oversight, library management

• Have worked with tools such as Altium, Allegro, KiCad, or similar

Nice to Have

• Experience with wireless power transfer (WPT)

• FPGA design experience (VHDL or SystemVerilog)

• Strong signal and power integrity knowledge

• Proficiency in C/C++, Python, or MATLAB

• Experience in regulated environments (especially ISO 13485)

• Background in implantable or Class III medical devices

Why Join iota?

• Mission with impact – see your work directly enable life-changing therapies

• Cutting-edge technology – work on a medical device that’s redefining what’s possible

• Growth opportunities – shape not only the product but also the future of the company’s technology roadmap

• Cross-functional exposure — work across hardware, firmware, systems, clinical, and manufacturing

If you want to work on ambitious, technically demanding hardware that could redefine medicine — we’d love to talk.
