This is a part-time equity/token-based cofounder opportunity. You will receive equity in Launch Legends
, Autheo
, and the WFO Creator Network
, along with token allocations in the Autheo blockchain. Salaried compensation is expected to begin within 4 to 5 months, following our node/token sales or funding.

Autheo is building a virtual machine platform redefining decentralized computation with sub-microsecond execution, billions TPS, and mathematically proven security.

As a part-time Senior QA UI/UX Engineer in an equity-based cofounder role, you’ll design and execute testing strategies for user interfaces and experiences in WASM-based runtimes, ensuring intuitive, responsive, and secure interactions for developers deploying smart contracts, DePIN compute tasks, and dApp deployments. This role is critical to validating that our platform surpasses Ethereum’s EVM and Solana’s SVM by embedding cryptography, homomorphic encryption, and zero-knowledge proofs into user-facing layers.

• UI/UX Testing Strategies
• Architect test plans for responsive interfaces optimized for cryptographic workflows validating 0.4µs response times at 1B+ TPS scale.
• Implement exploratory testing for DAG-based UIs supporting topological visualization of dependency-driven executions with zero usability friction.
• Design accessibility models integrating WCAG 2.2 standards for encrypted blockchain state and DePIN dataset interactions.
• Privacy-Preserving User Experiences:
  Develop test cases for zero-knowledge proof interfaces generating and validating 1‑5 ms proofs without data exposure.
• Implement threat modeling for differential privacy (ε = 0.5) in user interactions.
• Build secure enclave UI testing for 1 TB memory deployments.
• Reliability & Observability:
  Deploy UI testing to Kubernetes with 99.999% uptime; implement Open Telemetry tracing for 100% user interaction paths; build ML‑powered monitoring for UX optimization.
• Collaboration & Innovation:
  Collaborate with UX designers, frontend developers, cryptographers, and blockchain experts; lead UI/UX reviews for scalability and compliance; mentor QA teams and contribute to…
