Role: Senior Rust Engineer
Autheo is building a high-performance blockchain platform delivering 1B+ TPS, 200GB/s DePIN data flows, and secure execution with sub-microsecond speeds and robust encryption.
As a part-time Senior Rust Engineer in an equity-based cofounder role, you'll develop memory-safe backend components using Rust's ownership model for WebAssembly (WASM) runtimes, powering privacy-preserving smart contracts, DePIN compute tasks, and dApp deployments. This role is critical to surpassing Ethereum's EVM and Solana's SVM by embedding cryptography, homomorphic encryption, and zero-knowledge proofs for 0.4μs computations. If you're passionate about Rust's safety and Web3 innovation, join us to shape the backend for the next trillion-dollar decentralized economy.
Key Responsibilities:
1. Backend Component Design
* Build Rust-based modules for cryptographic operations with 0.4μs responses at 1B+ TPS.
* Implement DAG-based structures for workflow execution with zero overhead.
* Design secure pipelines with homomorphic encryption for blockchain/DePIN data.
2. Secure Execution Layers
* Develop zk-proof libraries generating 1-5ms proofs for runtime integration.
* Implement differential privacy (ε=0.5) for DePIN metadata protection.
* Build secure enclave modules for 1TB memory deployments.
3. Cross-Chain Integration
* Create GraphQL/gRPC APIs for cross-chain operations with sub-50ms latency.
* Apply saga patterns for transaction consistency across blockchains.
* Design webhook systems for <50ms event delivery to 10M+ dApp endpoints.
4. AI-Driven Optimization
* Build ML-driven load balancers optimizing 200GB/s flows (95% accuracy).
* Develop predictive scaling for transaction spikes 24+ hours in advance.
* Integrate GenAI for automated API schema generation.
5. Compliance & Governance
* Embed GDPR/CCPA/HIPAA-compliant routing with audit logging.
* Implement $THEO token-based governance for backend upgrades.
* Generate zk-proof audit trails for SOC 2 Type II/HITRUST certification.
6. Backend Reliability
* Deploy to Kubernetes with 99.999% uptime using circuit breakers.
* Implement OpenTelemetry tracing for 100% transaction paths (<15min MTTR).
* Build ML-based monitoring for resource optimization.
7. Developer Ecosystem
* Deliver SDKs (Rust/JS) for single-command backend operations.
* Build self-service consoles for API deployment in <5 minutes.
* Design sandbox environments for rapid developer testing.
8. Leadership & Innovation
* Collaborate with blockchain, AI/ML, and security teams for API integration.
* Lead backend architecture reviews for scalability and security.
* Mentor engineers and contribute to open-source Rust components.
* Publish at RustConf/Web3 Summit on backend innovations.
