Job Description

Senior Infrastructure Engineer - Unchained Capital Austin, TX or Remote (US-based)
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, and buying bitcoin directly to vaults with keys that you control. We\xe2\x80\x99re 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\xe2\x80\x99s 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\xe2\x80\x99s 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\xe2\x80\x99 data remains protected \xe2\x80\x93 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 \xe2\x80\x93 transparent, brutally honest, and based on proof of work. If that sounds like just the thing you\xe2\x80\x99ve been missing in your career up to this point \xe2\x80\x93 we look forward to seeing you in the inbox.
