Engineering / Financial Services

Mar 10

At Unchained Capital, our mission is to help clients truly own their wealth through bitcoin. Unchained products include multi-signature vaults utilizing collaborative custody, non-rehypothecated loans backed by bitcoin, andbuying bitcoin directly to vaults with keys that you control. We’re looking for someone to help us scale our cloud-based systems, further harden security, and increase development velocity.


Running infrastructure at Unchained is not your average sysadmin position:


  • We are one of the world’s largest bitcoin financial services firms and, as a result, are constantly being attacked by bad actors. We require hardened, proactive security measures and we are meticulous about access controls and physical/logical separation of responsibilities. Security is not an afterthought or a cost-center for us, it’s baked into our product and our company culture.
  • We meticulously screen and often avoid SaaS services to minimize our external surface area and ensure our clients’ data remains protected – even if this means increasing the number of systems we are directly responsible for maintaining.
  • Our workloads are not dynamic but they are sophisticated. The complexity of our product and the high cost of bugs means we deploy thousands of copies of our application through the development and testing lifecycle of each release.


Unchained Engineering is filled with talented, hard-working, and passionate engineers. We want to see a strong sense of ownership, intrinsic drive, a desire to learn and grow, and, ultimately, output and results. We hold each other to a very high standard and expect that accountability to be mutual. Finally, we strive to embody aspects of the Bitcoin ethos – transparent, brutally honest, and based on proof of work. If that sounds like just the thing you’ve been missing in your career up to this point – we look forward to seeing you in the inbox.
