Practichem is disrupting biotech instruments to accelerate cures to the world’s toughest diseases. Arista protein purification instruments are collaborative. Openness encourages reuse, speeding development of every vaccine and antibody. We believe instruments should be simple and friendly, like many mobile apps. We’re pioneering instruments-as-a-service, eliminating ownership problems like scaling, maintenance, and repair.

The role
The Embedded Systems Engineer owns the embedded device architecture and design that enables Arista device modules to work in unison. Our multidisciplinary team is on the forefront of biotechnology instrument development, and contributes cross-functionally to areas including motion control, fluidics, optics, and sensing.

We require a highly experienced Embedded Systems Engineer to create modular microcontroller-based devices. Create new device blocks, improve our existing device library, create and maintain firmware (C++), and middleware (Python3) with our engineering organization to develop, validate, and iterate more quickly.

Responsibilities

  • Maintain and expand Practichem’s internal library of schematic blocks
  • Create and maintain firmware for real time devices (motion, fluidics, optics, measurement)
  • Create and maintain lab and production level tools to install firmware on target devices
  • Collaborate with a team of experienced engineers and scientists to implement new devices to expand Arista instrument capabilities

Requirements

  • Bachelor of Science in Electrical Engineering - Computer Science
  • Expert skills in microcontrollers (ATmega/ATtiny preferred)
  • Expert skills in EDA tools (Altium preferred, or KiCAD)
  • Expert test equipment skills (DSO probing/protocol analysis/signal integrity)
  • Basic understanding of mechanical CAD (Solidworks/OnShape)
  • Expert skills in C++ embedded software development
  • Expert skills in FreeRTOS
  • Expert skills in inter-device communications  USB, SPI, I2C, Ethernet
  • Experience with design for safety (EN61010) and EMC compliance
  • Pass US DHS/Social Security Administration E-Verify

What sets us apart

  • Work on projects that matter.
  • Compensation is always competitive.
  • Work reasonable hours (rarely nights, weekends, or holidays).
  • Work remotely. Forever.
  • $500 in Cozy Cash to make your workspace your happy place. Whatever makes you happy - a squishy wrist rest, pet rock, mood ring, or how about a Maneki-neko?

Final word - fun
Make sure you’re having fun, finding your work rewarding. Make new friends, push yourself in new ways, and get exposed to new things. If you aren’t having fun at some level, you’ll be unhappy. We want you to love what you’re doing.
