Job Description

Who We’re Looking For

You are a software engineer who wants to build core technologies for scaling up systems to thousands of servers for managing and analyzing petabytes of data. In this position, you will work on building an event driven automation platform. You will be responsible for designing a product that is highly available, fault tolerant and responsive from the ground up. You will also evolve this platform beyond operational automation into new and exciting areas.


  • Build scalable infrastructure specifically targeted to the cloud environment
  • Design, document, and implement new web service APIs for internal and external services
  • Deploy and monitor applications efficiently 
  • Work closely with computational biologists and scientists to understand domain-specific needs
  • Enable integration of DNAnexus services with external systems 



  • 7+ years of core software development experience
  • Fluent in Ruby on Rails with 2+ years of experience
  • Fluent in at least 2 of the following languages: Javascript, Python, Java, C++
  • Extensive knowledge of AWS, IAM policies, VPC and security groups setups,  CI/CD tools, docker based deployments and Log aggregation systems like sumo logic/splunk etc. 
  • Experience using Linux and comfortable working in a Unix shell
  • Team-oriented, with strong communication skills
  • Strong computer science background, including low-level systems and algorithmic complexity
  • Demonstrated ability to pick up new technologies and quickly adapt to new paradigms

What We Care About

  • Curiosity and humility. We are dedicated to learning and constantly improving.  We hope you also value "unknown unknowns" and have a natural drive to figure out how everything works.
  • Agility and ownership. Our teams have a high degree of freedom on how they build their systems, but they also take full ownership of what they deliver, in the long run.
  • Monitoring and automation. We strongly believe that a fully automated system is key to rapid iterations, while an extensive set of metrics highlights what needs to be done.
  • Balancing research and product. We value staying up-to-date on cutting edge research, while also shipping meaningful products enabling researchers to fulfill their mission.
