ROLE- Senior API & Interoperability Engineer
Autheo is building the world's first unified cross-chain API platform, orchestrating 1M+ TPS between Ethereum, Solana, Polkadot, Cosmos, and 20+ ecosystems with sub-50ms latency, zero-knowledge security, and seamless dApp composability across $1T+ in total value locked.
As a part time Senior API & Interoperability Engineer, you'll design and implement REST, GraphQL, and gRPC bridges, protocol adapters, and event systems in Go and Rust-powering atomic DeFi swaps, sovereign data federation, AI model marketplaces, and DePIN orchestration across diverse blockchains.
This mission-critical role advances Autheo's Layer-0/Layer-1 interoperability stack through AI-driven protocol translation, unifying fragmented ecosystems into one seamless multi-chain fabric. If you're passionate about protocol engineering and cross-chain systems, this is your opportunity to help shape the API layer connecting the next trillion-dollar decentralized economy:
Key Responsibilities
1. Cross-Chain API Architecture
• Architect GraphQL Federation and gRPC gateways unifying Ethereum, Solana, Polkadot, Cosmos, and Autheo's Layer-1 into a single API schema.
• Implement high-performance adapters translating REST/SOAP/Web3 RPC calls into secure, unified APIs capable of 1M+ TPS.
• Build event streaming systems delivering blockchain logs and transactions to dApps under 100 ms latency.
2. Secure Bridge Protocols
• Develop atomic cross-chain swap engines with zk-proof settlement and threshold-signature validation across 1,000+ validators.
• Embed advanced cryptography for transaction confidentiality and fault-tolerant bridge custody.
3. Zero-Knowledge Verification & Privacy
• Implement zk-SNARK/STARK layers for proof-of-state without data exposure.
• Enable confidential cross-chain asset transfers and privacy pools supporting regulatory auditability.
4. Multi-Protocol Event Orchestration
• Design Kafka-based cross-chain event buses processing tens of billions of events daily.
• Apply saga orchestration patterns ensuring consistency across heterogeneous blockchains.
• Engineer global webhook networks providing < 50 ms notifications with exactly-once delivery.
5. AI-Driven Translation & Routing
• Build ML routing engines that dynamically select optimal bridge paths by latency, liquidity, and threat modeling.
• Develop protocol translation layers that auto-convert EVM calls to Solana programs or Cosmos modules with zero manual effort.
• Implement predictive bridge capacity planning and anomaly detection.
6. Compliance & Governance Automation
• Implement GDPR/CCPA/HIPAA-aware routing enforcing regional compliance.
• Design cross-chain governance where $THEO holders vote on protocol upgrades, fees, and security parameters.
• Generate zk-proof audit trails supporting SOC 2 Type II and HITRUST certification.
7. Reliability & Observability
• Deploy bridge microservices to Kubernetes with 99.999% uptime, circuit breakers, and cross-chain retry orchestration.
• Implement distributed tracing (Ethereum→Solana→Cosmos) with OpenTelemetry and < 15 min MTTR.
• Integrate ML-based health monitoring for liquidity and protocol-divergence alerts.
8. Developer Ecosystem & SDKs
• Deliver unified SDKs (Go/Rust/JS/Python) enabling single-command cross-chain operations.
• Build self-service bridge consoles and schema explorers for instant API deployment and testing.
• Design sandbox environments for rapid developer onboarding.
9. Collaboration & Leadership
• Work across backend, blockchain, AI/ML, and security teams to maintain consistent API contracts.
• Lead interoperability architecture reviews and mentor integration engineers.
• Contribute to open-source projects establishing Autheo as a thought leader in cross-chain innovation.
10. Research & Continuous Innovation
