Cryptographic Engineer

Spring Labs



About Spring Labs:
Spring Labs is redefining how data is exchanged for the new age of data sharing, security, and consumer privacy through decentralization. Our Spring Protocol Tech Stack, which includes the use of Blockchain and Cryptography, allows institutions to share information among themselves to verify identities and reduce fraud - all while protecting consumer data.

There are a few things we look for at Spring Labs in all qualified candidates, regardless of role or team. First, we look for signals that a candidate will thrive in a culture like ours, where we act like owners, empower and trust others, place ideas over hierarchy, and expect a high level of collaboration and performance. Second, we expect all employees to commit to our mission and become active culture carriers. Finally, we look for humble people, with the desire and capacity to grow and share their expertise.

We are currently seeking an experienced cryptographic engineer to join our Research and Engineering teams to implement the next evolution of these systems. This role is responsible for the specification and implementation of applications leveraging trusted execution environments, secure enclaves, and many cryptographic primitives. This role requires heavy collaboration with the Software Engineering and Product teams to ensure our newest products are effective, usable, performant, and scalable.

Spring Labs is typically an in-office culture. Due to Covid, we are currently utilizing a hybrid approach, however, based on the ideal candidateโ€™s location, full-remote is acceptable.
