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.

Key Responsibilities:

• 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.

• 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.

• Reliability & Observability

*Deploy API testing to Kubernetes with 99.999% uptime.

*Implement OpenTelemetry tracing for 100% transaction paths (<15min MTTR).

*Build ML-powered monitoring for API optimization.

• Collaboration & Innovation

*Collaborate with backend developers, cryptographers, blockchain consensus experts, and DePIN architects.

*Lead integration reviews for scalability and compliance.

*Mentor QA teams and contribute to open-source API testing tools.

*Publish at WasmCon 2026 on integration innovations.

Qualifications:

Required:

*Bachelor’s/Master’s in Computer Science or equivalent.

*5+ years in API/integration testing for high-throughput systems.

*Expertise in Kubernetes, OpenTelemetry, and API frameworks.

*Proficiency in zk-proofs, distributed integration testing, and compliance auditing.

Preferred:

*Background in blockchain/DePIN API integration or AI infrastructure.

*Experience with open-source API testing tools or multi-protocol setups.

*Contributions to API standards or patents in reliability engineering.

Soft Skills:

*Precision in integration design and optimization.

*Strong technical communication and collaboration.

*Passion for scalable decentralized ecosystems.

Deliverables (90 Days):

*API test plans for 0.4μs endpoints with zero downtime.

*DAG-based integration tests for topological APIs.

*Homomorphic encryption API validations for exabyte scales.

*zk-proof API testing with 1-5ms validation.

*Secure enclave API for 1TB memory.

*Open-source API components driving 100+ integrations.

*WasmCon 2026 presentation on integration leadership.
