Senior Backend Engineer (Go)

At Horizon, we’re building a New Dimension where Internet economies are fun, accessible, and for the benefit of all participants. We have two amazing products to make this real: Sequence, which consists of i) a friendly crypto + Web3 wallet, and ii) a seamless developer platform for Ethereum, NFTs, Web3, DeFi and Dapps. And Skyweaver, a digital trading card game—powered by Sequence—where players actually own the game items (NFTs) they win and purchase. For the first time, gamers can easily and securely sell and trade their items. Sequence is poised to drive Web3 adoption on a massive scale by making blockchain easy, fun and powerful for users and developers. And, Skyweaver has the chance to become a groundbreaking video game with its unprecedented player-owned economy, novel gameplay, and an already fervent community. While the challenge is hard, we find it incredibly fun. And we have the ingredients to make it happen: a well-capitalized company with some of the best investors in the world (Reddit co-founder, Coinbase), an amazing team of leaders in the blockchain space, engineers who have built widely popular open source, a former top McKinsey strategy consultant, gaming industry veterans, and founders who have built and sold successful companies.
