Compensation & Growth Path
This is a part timeequity / token-based cofounder opportunity. You will receive equity in Launch Legends Autheo and the WFO Creator Network along with token allocations in the Autheo blockchain. We have already completed an initial financing round to support infrastructure and marketing and are currently in discussions with VCs and crypto investors to fund expansion and salaries. Salaried compensation is expected to begin within 4 to 5 months following ournode tokensales or funding.
Role: Senior DeFi Engineer - Infrastructure (with Blockchain Experience)
Autheo is building a sovereign data platform unifying petabyte-scale pipelines federated lakehouse analytics and 200GB/s streaming with 25μs query latencies unbreakable encryption and GDPR/HIPAA compliance.
As a part-time Senior DeFi Engineer - Infrastructure in an equity-based cofounder role youll design scalable DeFi backends using Scala and Kubernetes powering liquidity aggregators cross-chain routers and order books across DePIN networks. This role is critical to enabling sub-millisecond finality and post-quantum signatures at scale. If youre passionate about DeFi infrastructure and Web3 join us to shape the backbone layer for the next trillion-dollar decentralized economy.
Key Responsibilities:
1. DeFi Infrastructure Architecture
* Build liquidity aggregators routers and order books for DAG BFT consensus.
* Implement bridges and relayers for 20 chain asset transfers with sub-millisecond finality.
* Design oracle networks for tamper-proof feeds and MEV-resistant DeFi operations.
2. Scalability & Optimization
* Optimize backends with CQRS PostgreSQL sharding and Kubernetes for billions of transactions.
* Integrate KYC/AML-compliant fiat ramps while preserving non-custodial DeFi principles.
* Ensure 50B TPS scalability with distributed systems and consensus algorithms.
3. Security & Monitoring
* Embed post-quantum signatures for unbreakable DeFi infrastructure security.
* Develop anomaly detection tools and automated audits for real-time risk mitigation.
* Generate zk-proof trails for compliance and infrastructure governance.
4. Interoperability
* Design infra compatible with Ethereum Solana Polkadot and Cosmos ecosystems.
* Implement high-throughput relayers for seamless cross-chain liquidity pooling.
* Integrate CEX APIs like Binance for hybrid custodial/decentralized execution.
5. Developer Ecosystem
* Deliver SDKs ( for single-command infra deployments.
* Build self-service consoles for DeFi backend scaling in <5 minutes.
* Create sandbox environments for rapid infrastructure testing.
6. Leadership & Innovation
* Collaborate with DeFi primitives data and AI/ML teams for integration.
* Lead infrastructure reviews for reliability and performance.
* Mentor engineers and contribute to open-source DeFi infra components.
* Publish at Consensus/SBC on DeFi infrastructure innovations.

Required:
* Bachelors/Masters in Computer Science Engineering or equivalent.
* 7 years building DeFi infrastructure with aggregators bridges or oracles.
* Expertise in Scala Go and tools like AWS Docker RabbitMQ.
* Proficiency in cross-chain mechanisms liquidity protocols and security audits.
Preferred:
* Background in Polkadot/Substrate contributions or enterprise DeFi networks.
* Experience with open-source bridges or oracle decentralization.
* Contributions to Axelar/Wormhole standards or patents.
Soft Skills:
* Precision in infrastructure architecture and scaling.
* Strong technical communication and collaboration.
* Passion for robust Web3 DeFi ecosystems.
Deliverables (90 Days):
* Cross-chain DeFi bridge prototype with 5M TPS transfers.
* Scalable oracle infrastructure for real-time DeFi data.
* KYC-compliant fiat ramp with non-custodial support.
* Post-quantum signature layer for bridges and routers.
* SDKs for zero-config infra operations.
* Open-source DeFi infra toolkit driving 100 integrations.
* Consensus 2026 presentation on DeFi infrastructure leadership.
