Software Engineer, Fullstack
HEX is a decentralized, blockchain-based cryptocurrency and smart contract protocol that allows users to 'mine' rewards by locking (staking) their HEX tokens for a chosen period of time, with longer commitments yielding larger rewards. It operates on Ethereum and PulseChain with no central entity, middlemen, or minimums, and serves individual crypto holders and investors seeking yield through time-locked staking.

About HEX
HEX presents itself as a finished, immutable, unstoppable smart contract that has undergone three independent audits from top blockchain auditors. It has no central entity or middlemen — users mint their own rewards by running code to lock their HEX tokens for a period ranging from 1 to 5555 days, then minting the rewards afterward, with longer commitments and larger stakes rewarding higher yields ('Longer Pays Better'). The protocol touts a capped inflation rate of 3.69% and a publicly viewable future locked-supply schedule so users can anticipate large miners' unlock events. HEX operates on both Ethereum and PulseChain, and users interact with it via MetaMask wallets, acquiring PLS on PulseChain and swapping for HEX via PulseX, then mining/minting rewards through go.hex.com. The site markets itself toward individual retail crypto investors interested in long-term, high-yield staking of a decentralized asset, citing dramatic historical price appreciation as a selling point.
Skills
About the Role
You'll work across the full stack, from complex user-facing interfaces and browser-based IDEs to backend language parsers and SQL generation. You'll build observability tools that give data teams control and visibility into agent performance, usage metrics, and conversational audit trails. You'll design and implement AI context systems that manage diverse inputs such as free-form rules, certified SQL queries, and deterministic semantic models. You'll create robust, full-stack workflows that let data teams govern, debug, and curate the Hex agent's knowledge, and you'll tackle challenging back-end problems related to SQL compilation and semantic model development, as well as complex front-end UX challenges to present technical information clearly and intuitively. This role is hybrid, with 2 days per week in office based out of the NYC or SF offices.
