ROLE Senior API & Interoperability Engineer
Part-Time / Remote Autheo Layer-Zero Infrastructure for the Connected Web
Autheo is building the worlds first unified cross-chain API platform orchestrating 1M TPS bridges across Ethereum Solana Polkadot Cosmos and 20 ecosystems. Our mission: deliver sub-50 ms latency zero-knowledge security and AI-driven interoperability to power the next trillion-dollar multi-chain economy.
Were seeking a Senior API & Interoperability Engineer to design and deploy production-grade REST GraphQL and gRPC bridges protocol adapters and event systems in Go and Rustcreating the core interoperability fabric for Web3 AI DeFi and decentralized infrastructure.
Key Responsibilities
1. Cross-Chain API Architecture
Architect GraphQL Federation and gRPC gateways unifying Ethereum Solana Polkadot Cosmos and Autheos 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 1000 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 (EthereumSolanaCosmos) 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
Stay current with IBC v2 CCIP v2 XCM advancements and secure bridge research.
Publish and present Autheos work at leading Web3 and API conferences.
Qualifications
Required
- Bachelors or Masters in Computer Science Distributed Systems or Software Engineering.
