Role:
Senior

QA API Integration Engineer Autheo is building a virtual machine platform redefining decentralized computation with sub-microsecond execution, billions TPS, and mathematically proven security. As a part-time QA API Integration Engineer in an equity-based cofounder role, you’ll design and validate API endpoints and system integrations for WASM-based runtimes, ensuring seamless connectivity for smart contracts, DePIN compute tasks, and dApp deployments. This role is critical to confirming that our platform surpasses Ethereum’s EVM and Solana’s SVM by embedding cryptography, homomorphic encryption, and zero-knowledge proofs into integration layers for efficient 0.4μs encrypted computations.

If you’re passionate about API validation and end-to-end testing, join us to integrate the sovereign computation layer for the next trillion-dollar decentralized economy.

• 1. API Testing Strategies
  • Architect test plans for API endpoints validating 0.4μs responses.
  • Implement integration tests for DAG-based APIs supporting topological workflows with zero downtime.
  • Design endpoint validations for homomorphic encryption in blockchain state and DePIN integrations.
• 2. Privacy-Preserving Integrations
  • Develop tests for zero-knowledge proof APIs generating 1-5ms proofs in integrated systems.
  • Implement threat modeling for differential privacy (ε=0.5) in API calls.
  • Build secure enclave API testing for 1TB deployments.
• 3. Reliability & Observability
  • Deploy API testing to Kubernetes with 99.999% uptime.
  • Implement Open Telemetry tracing for 100% transaction paths (
