Immunotherapy Technology Fellow

HelixNano is a Y Combinator and venture backed biotech startup based at LabCentral in Cambridge, MA. We use synthetic biology to develop novel therapeutic modalities for the world's most lethal cancers. 

We are looking for an experienced scientist to lead the development of a new approach to boost the efficacy of personalized cancer vaccines. You can read more about this Schmidt Futures -supported project here

We want to hire you because you are passionate about developing technology and transforming the landscape of cancer therapeutics. You prefer ingenuity to brute force, think things through from first principles and dare to believe in your own reasoning. You have the energy and drive to work independently when needed, but also care deeply about your teammates, are willing to help them grow and learn from them in return. 

Most importantly, you have the courage to take on problems others think are impossible – and the humility 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. We offer a competitive salary, stock options and benefits, a great work environment in the vibrant community of LabCentral, and the opportunity to do exciting science at startup speed — but in collaboration with some of the best research institutes in the world. 

This is a pioneering role with large potential for career growth, and comes with a lot of autonomy to work towards the goals we set together.
