Symbiont is Hiring a Senior Frontend Developer

Job Description is a financial technology startup working to bridge the gap between cryptocurrency technology and mainstream finance. Our team consists of known leaders in both fields, with three of its founders having co-founded the Counterparty platform, and its other founder behind two alternative trading systems and the original LavaFlow ECN.
