About The Position

We’re offering a unique opportunity to join Launch Legends (and Autheo) as a part-time Equity Cofounder. Founded nearly four years ago, Launch Legends is at the forefront of bridging Web3 blockchain technology with the next evolution of Web2 integration—bringing businesses on-chain through enterprise-grade solutions, DePIN innovations, and decentralized financial infrastructure. Our flagship project, Autheo, is an AI enabled Layer-Zero OS with an integrated Layer-1 blockchain and complete decentralized infrastructure thast includes decentralized compute, storage, identity, and service marketplaces, as well as a Full-stack development enveronment (DevHub)—engineered for scalable enterprise adoption, developer innovation, and real-world blockchain integration. 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:

Requirements

Bachelor’s or Master’s in Computer Science, Distributed Systems, or Software Engineering.
5+ years in protocol or API engineering, including cross-chain bridges or large-scale (1M+ TPS) integrations.
Production experience with Go, Rust, and GraphQL Federation or gRPC.
Proven success implementing IBC, XCM, CCIP, or equivalent bridge protocols.
Strong grasp of zk-proofs, threshold signatures, and atomic swap mechanisms.
Hands-on expertise with Kubernetes, event streaming (Kafka), and distributed tracing.
Deep understanding of security, fault tolerance, and cryptographic primitives in blockchain environments.

Nice To Haves

Background in DeFi, AI data orchestration, or multi-chain compute infrastructure.
Experience developing multi-language SDKs or open-source bridge tooling.
Contributions to IBC/CCIP standards or cross-chain interoperability research.
Published papers or patents in distributed systems or cryptography.
Precision in systems design and protocol optimization.
Excellent technical communication and cross-team collaboration.
Strategic thinker passionate about interoperability and developer empowerment.

Responsibilities

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.
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.
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.
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.
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.
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.
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.
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.
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.
Research & Continuous Innovation
Stay current with IBC v2, CCIP v2, XCM advancements, and secure bridge research.
Publish and present Autheo’s work at leading Web3 and API conferences.
