Software Engineer, Foundations
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 help design, maintain, and evolve the core systems used across Hex. This role is centered on backend architecture and shared infrastructure, with responsibility for APIs, realtime communication, data access frameworks, job orchestration, and internal admin tooling. You'll work closely with product engineering teams to understand their needs, then turn common patterns into robust, reusable systems. You'll help define standards, influence architecture, and raise the quality bar across the backend. Frontend experience is helpful for understanding end-to-end workflows, but this role is primarily backend-focused.
Requirements

- Experience working with Typescript/Node.js and SQL
- Experience building and maintaining shared backend systems or frameworks used by multiple teams
- Strong understanding of API design, distributed systems, and asynchronous workflows
- Experience working with relational databases and data modeling at scale
- Familiarity with background job systems, queues, or workflow orchestration tools
- Comfort operating and evolving production systems over time
- Experience with cloud infrastructure (AWS preferred)
- Strong communication skills and a collaborative, leverage-oriented mindset
Responsibilities
- Design and build backend frameworks and services used across the company
- Own and evolve critical shared systems, including APIs, realtime transport, and job orchestration
- Improve reliability, performance, observability, and security of foundational backend infrastructure
- Partner with product teams to turn recurring needs into shared abstractions
- Lead technical design discussions and help set architectural direction
- Drive refactors, migrations, and system upgrades that reduce long-term complexity
- Improve internal tooling to support debugging, operations, and customer-facing workflows
- Mentor other engineers and contribute to strong engineering standards and practices
