Chief Technology Officer

About the role: Most software can be patched after it ships. A smart contract change cannot be taken back once it is signed. USSE needs a founding Chief Technology Officer who reads code, owns a live on-chain platform end to end, and is the person who says a change is ready, or that it is not ready yet. The platform today Our technology is further along than our business, and you should know exactly how far:* Live in production on Ethereum mainnet and on Base, an Ethereum Layer 2 network, since July 4, 2026.* The token sale contracts are deployed but paused. No tokens have been sold, and token trading is not switched on.* A built-in token exchange, staking, liquidity programs, and on-chain governance are built and waiting to be activated. Deciding when each one is safe to turn on is part of this job.* The company is pre-revenue and has not raised a priced equity round. What you will run* Smart contracts on Ethereum and Base. Most can still be upgraded, and making any of them permanent is a one-way decision.* The API, databases, real-time delivery, and the indexers that read both blockchains.* DEEP Mail, our end-to-end encrypted messaging secured with zero-knowledge proofs, alongside TheWall social feed, the Media Marketplace, and on-chain identity.* Gasless actions: a user pays in ETH on Ethereum and the action completes on Base.* The web application, the internal admin systems, and an Android app.* Security monitoring, secrets management, and the controls around the company's keys. Decisions that will be yours* Whether an upgrade is ready to sign, and what evidence proves it worked afterwards.* When a contract should stop being upgradeable for good.* The order and timing for switching on the exchange, staking, liquidity, and governance features.* Which security audits happen before each activation, and who performs them.* How company keys are held and how a signing is approved, set with the CFO.* How the platform proves who changed a record, when, and who approved it, so an auditor or regulator can check the answer. The details of each area are covered in the interviews. What you bring Required* 10+ years building software, including senior technical leadership such as CTO, VP of Engineering, or principal engineer.* Hands-on Solidity and EVM depth: proxy upgrade patterns, storage layout, contract size limits, and the ways an upgrade can fail.* Production experience running backend services and databases that other people depend on.* A security-first instinct for systems that cannot be rolled back, including key custody and multi-step approvals.* You still write and review code, and you expect to keep doing it.* You are ready to trade a large salary today for founding ownership in what you run. Strongly preferred* Smart contract security audits, as the auditor or as the team being audited.* Ethereum Layer 2 networks and cross-chain messaging.* Applied cryptography, such as zero-knowledge proofs or end-to-end encryption.* Engineering in fintech, payments, or another regulated industry.* Incident response and written post-incident reviews. How you work* You would rather stop a release than ship something you have not verified.* You trust a check only after you have watched it fail against the broken case.* You write down what you have confirmed and what you have only assumed. Where the CTO works The CTO works from our corporate office in Hutchinson, Kansas. You can begin on a hybrid schedule and then move to Hutchinson to work in person, because release decisions and incidents go better with the people involved in the same room. We will set the timing of the move with you. Pay, ownership, and the risk Pay is negotiated with the right candidate and is expected to combine:* A cash salary* Founding equity in the company, vesting on a standard schedule* Token compensation where offered, governed by its own agreement, vesting, lockup, and securities law None of it depends on how much money the company raises. A live platform is not a funded company. We have no revenue, no tokens sold, and no equity round yet, so cash may be limited or deferred until funding arrives, and equity or tokens could end up worth nothing. If you want to set the technical course of a live on-chain platform and own part of the outcome, apply.
