Job description

Build Robots for Bioscience

It sounds like science fiction, but we turn science fiction into science fact. Our robotic systems are used in research labs worldwide to accelerate the work that makes life better for everyone. Whether it’s DNA, diseases, drugs, or diagnostics, there’s still so much to do — and that’s why we need you.

What You’ll Do

Join our Software Team — the brains behind the machines. We write the code that makes the robots go:

  • Design, build, and maintain software for robotic instruments and automation workflows
  • Write code that controls motors, actuators, pumps, heaters, and more
  • Integrate instruments, sensors, and third-party systems
  • Integrate multiple robots together into complete solutions
  • Build UIs and HIDs for controlling the robots
  • Improve the reliability, testability, and maintainability of existing software
  • Work closely with electrical, mechanical, applications, service, and product teams
  • Applications range from fluid dispensing to bacterial identification to chemical measurements and beyond

From customer-specific integrations to entirely new capabilities, you'll take projects from concept through delivery, balancing new development with the practical realities of maintaining and supporting systems already in the field. You’ll work on a wide array of challenges that use every skill you bring to the table, and you’ll learn new skills with us too.

What We’re Looking For
  • Programming experience: 10+ years recommended
  • Languages: C# on modern .NET
  • Education: Degree in Computer Science or Software Engineering, or equivalent experience
  • Technologies & Tools: TCP/IP networking; SQL databases (MS SQL Server and SQLite are a plus); Visual Studio; Git version control
  • Ability to work both independently and in teams
Bonus Skills

We don’t expect all of these skills, but any you have are a plus.

  • Robotic motion control experience
  • Computer vision and AI/ML algorithms
  • Low-level I/O & firmware/embedded code
  • Desktop UI code (we use WPF and Avalonia)
  • Coding on both Windows & Linux
  • Biology or chemistry knowledge is a bonus, but not required — we can teach you what you need
Work Environment

Because this role works directly with robotic systems, instruments, and hardware integration, the position is expected to be onsite during onboarding and major development/debug phases. Hybrid work may be considered later based on project needs. This is not a remote position.

What We Offer
  • Competitive compensation
  • Benefits include medical, dental, and vision coverage options, 401(k) with company match, paid time off, and eligibility for performance-based bonus program.
Who You Are

Smart, capable, collaborative, and passionate about building technology that matters.

You can write code anywhere — but here, your code will help change the world.

Sounds interesting? Send us your resume and let’s talk.

We are an Equal Opportunity Employer and consider all qualified applicants without regard to race, color, religion, sex, national origin, age, disability, veteran status, or any other protected status.
