Protein Explorer

HelixNano is a Y Combinator and venture backed biotech startup based at LabCentral in Cambridge, MA. Our mission is to solve gene delivery. We leverage the full toolkit of synthetic biology to safely and reliably express transgenes in humans — for next-generation gene therapies, genome engineering and beyond. 

We are looking for an experienced scientist to drive the design and testing of synthetic proteins that power our platform. 

We want to hire you because you believe that even though biology is unpredictable, we now have the tools to engineer it like never before, from high-throughput DNA synthesis to computational protein design. You have used these together with your biological insights to solve a hard problem and, if necessary, mastered new tools to get the job done.  You are passionate about research and want to make a real-world impact. You are excited to work with teammates from different disciplines and to learn from them.

Most importantly, you have the confidence to take on problems others think are impossible — and the humility and flexibility to change your approach if Nature refuses to conform to your ideas. And when things don't go smoothly, you are kind to others and yourself. 

If this sounds like you, please apply. This is a pioneering role with a large potential for career growth. 


  • Ph.D. or equivalent, 5+ years of research experience
  • Prior experience with protein biochemistry
  • Prior experience designing and testing proteins
  • Mammalian cell culture experience
  • A solid background in basic molecular biology and related techniqes
  • Background in immunology would be a plus
