Culture Biosciences (W18)
We grow cells for biotech companies.

Senior Electrical Engineer

South San Francisco, CA
About Culture Biosciences

Culture Biosciences grows organisms for biotech companies. We've built the first cloud bioreactor facility. Here’s how it works:

  1. Our customers are experts in DNA design -- they send us their genetically engineered organisms for testing.
  2. We grow their cells in our bioreactors to examine the efficacy of different protocols and their effect on yield and productivity.
  3. Our customers monitor the state of things live via our website. At the end we send them some samples for storage or more custom analysis.

Our customers genetically modify organisms to produce new therapeutics, materials, fuels and foods. We help them quickly run experiments and develop manufacturing processes so they can get their products to market faster. We've built proprietary software and automation systems to make operating our bioreactors more efficient than existing systems. We also provide customers with new software tools that help them analyze and contextualize their data. We are currently serving a number of biotech customers and scaling out our infrastructure.

We are a Bay Area company backed by leading venture funds including YCombinator and Verily Life Sciences. We are made up of mechanical, software, biomedical and chemical engineers who worked previously at Google X, Facebook, MIT, CalTech, Bristol Myers Squibb, and Lawrence Berkeley National Labs. Our team is passionate about enabling high-throughput, reproducible science. We value curiosity, clear communication, kindness, and collaboration. We're also committed to building a diverse team.

About the role

Culture Biosciences grows organisms for biotech companies. We've built the first cloud bioreactor facility. Here’s how it works:

  1. Our customers, biotechnology companies, design organisms (bacteria, yeast, mammalian cells) to produce products (materials, therapeutics, food).
  2. We grow their cells in our bioreactors to optimize the yield of their products. Ultimately, we help our customers get their products to market faster.
  3. Our customers receive their experimental results live on our website.

Our cloud bioreactor facility is made possible by custom software and automation technology that our team develops. The automated infrastructure is also more efficient to operate than traditional equipment. Our software also provides quick and simple data analysis, enabling customers to analyze reams of data quickly. 

The Role

Culture Biosciences is looking for a Senior Electrical Engineer. Your focus will be on designing, building, installing, and testing new bioreactors. You will be the most experienced Electrical engineer on the team and you will be responsible for building and delivering large parts of our hardware roadmap.


What you'll do

  • Help define our hardware engineering culture. 

  • Lead the electrical & embedded systems design of new bioreactors.

  • Write embedded code to control actuators and read sensors.

  • Design and install custom robotic automation systems

  • Learn about fermentation, cell culture, and biomanufacturing

In return, we will support you by:

  • Placing a high degree of trust in your ideas and execution.
  • Bringing you up to speed in the domain of biomanufacturing.
  • Providing a low-stress work environment.
  • Making ourselves available for collaboration.
  • Caring about you as a whole person, not a “resource”.

Projects on our horizon

  • Building new electrical components of existing, installed bioreactors to improve quality and robustness.
  • Collaborating with mechanical engineers to design and build new types & sizes of bioreactors. 
  • Developing new lab automation systems, such as auto-sampling systems and shake flask monitoring, that improve the quality & efficiency of our operations. 

About you:

  • At least 6 years of work experience designing, building, and testing electronics.
  • You’re proactive and a self-starter
  • You’re kind, curious, and enjoy learning new things.
  • You value communication and connection on a multidisciplinary team
  • You care that you’re building something that solves a problem and helps end-users
  • You are highly proficient in at least one EDA platform (e.g. Altium, EAGLE).
  • You are comfortable working with PCB fabrication and assembly manufacturers.
  • You are familiar with best practices for mixed-signal design, EMI, and power supply design.
  • You are comfortable working with common embedded communication protocols (e.g. SPI, I2C, and RS232).
  • You have experience working with sensors (e.g. optical sensors, encoders, and scales). 
  • You have experience working with actuation (e.g. motors, linear rail, robotic arms).
  • You’re not a pure software engineer, but you’re able to write embedded software like device drivers (mostly in C/C++) and you’re familiarly working with git and CI/CD. 
  • Bachelor’s degree in Electrical Engineering, Robotics, or Mechatronics or a related field. If you have a Ph.D., only 3 years of work experience are required to be eligible for this role.

About Culture

  • Competitive salary and equity. 
  • Health insurance (PPO), Dental, Vision, and Life.
  • PTO: 3 weeks and 10 days of company holidays. 
  • Parental leave policy: 12 weeks. Full salary paid.
  • We have a machine shop onsite for rapid prototyping --  Haas CNC, manual mill, lathe, laser cutter, 3D printers, vacuum former and more.
  • We offer free, onsite breakfast, lunch, snacks, coffee as well as a gym with showers and classes.

We seek to build a company that promotes inclusion and improves the diversity of our industry as a whole. We look forward to working with scientists and engineers from all walks of life. Culture Biosciences provides equal employment opportunities to all employees and applicants.
