About Us

Hi there. We’re GridPlus. We’re a small team of experts in decentralized networks, embedded firmware, and applied cryptography. We've built the world's most secure and flexible cryptocurrency hardware wallet, the Lattice1, and we'd like your help in making it the world's best tool for securely storing and using your crypto.

Interested? Send your resume to careers@gridplus.ioPlease feel free to provide anything else you think is relevant such as coding samples (Github, Stackoverflow, etc.) or blog posts, we’d love to take a look!

Available Roles

    Software Engineer - Phonon Protocol (Remote)

    Phonon is a brand new, layer zero, chain-agnostic protocol enabling linearly scalable, private, peer to peer, zero fee transfers of blockchain assets made possible by leveraging secure hardware.

    GridPlus released the working Alpha code, spun out the protocol's ownership, and we're looking for a talented backend focused software engineer with an interest in blockchains and security to help GridPlus develop a class leading Phonon client and contribute to the development of the protocol itself.

    This is a project in its early stages with huge potential. This position would be great for a creative and technically excellent engineer who wants to get involved in product and protocol design for a novel system with a wide variety of potential applications and technical challenges alike.
