We work on challenges such as trust-minimized micropayments, low-latency request processing, data verification, and dynamic pricing. We’ve published research at prestigious AI conferences like NeurIPS and developed novel optimization algorithms. We make web3 smarter and verifiable.\nWe are a core developer of The Graph protocol ($1B+ market cap), an indexing protocol for organizing and accessing the world’s data. We are also the parent company of Odos, a market-leading liquidity aggregator that supports $5B+ in monthly trading volume.\nYou can learn more about Semiotic Labs at semiotic.ai or by watching this presentation.\nThe Role\nWe’re looking for a Rust Engineer who’s excited about building scalable, cryptographically secure systems for web3 infrastructure. You’ll work on GraphTally, implementing performant, reliable components that enable stateless, one-way payment channels at scale. This role is ideal for someone who thrives on solving protocol design challenges and building robust, production-ready Rust code.\nThis role is perfect for those who thrive in a multidisciplinary team solving complex, unsolved problems through research and engineering. You'll excel here if you're excited about working on a small, agile team where your daily work drives innovation—both internally and across the web3 ecosystem. Above all, you should be passionate about delivering real value to users.\nWhat You’ll Do\nDesign, implement, and maintain core components of the GraphTally protocol in Rust.\nCollaborate with researchers and protocol engineers to refine and evolve the architecture.\nOptimize signature verification, message processing, and batching for high-throughput performance.\nImplement secure state transition logic, trust-minimized payment flows, and smart contract interactions.\nWork closely with smart contract engineers to ensure seamless on-chain integration (mainly on L2s like Arbitrum).\nWrite clean, testable, and efficient code with a focus on security and correctness.\nContribute to technical documentation, specifications, and developer tooling to support GraphTally adoption.\n\n3+ years of professional experience writing high-performance, production-quality async code in Rust.\nExperience in designing and implementing remote APIs (REST, JSON-RPC, gRPC)\nExperience in responsive microservices design and development\nExperience with databases (Postgres, Redis)\nExperience with Docker.\nDeep understanding of cryptographic primitives, especially ECDSA and digital signature schemes.\nProficient with Rust’s async/await model, leveraging futures, tokio, or async-std\nUnderstanding of asynchronous state machines for managing complex protocol flows\nFamiliarity with zero-knowledge proofs, state/payment channels, or escrow mechanisms is a plus.\nStrong grasp of trust-minimized systems, distributed protocols, or payment rails in a web3 context.\nExperience working with Ethereum L2s (like Arbitrum, Optimism) and integrating with smart contracts.\nProficiency with testing, benchmarking, and debugging asynchronous Rust applications in the context of web3, using tools like anvil.\nClear communication, curiosity, and a strong sense of ownership.\n\nBonus Points\nFamiliarity with The Graph protocol or Indexer infrastructure.\nExposure to decentralized microservice architectures or multi-agent systems.\nPrior work on gas-optimized smart contracts or cryptographic batch verification.\nExperience with zkSNARKs, RAVs, or verifiable off-chain aggregation techniques.\n\nWhy Join Semiotic Labs\nBe part of a small, high-caliber team solving cutting-edge problems in decentralized infrastructure.\nWork on a deeply technical and meaningful mission that helps scale web3.\nShape the direction of a foundational protocol used by agents and services across the ecosystem.\nFully remote, async-friendly team with competitive compensation and token upside.","company":"Decircle","rawCompany":"decircle","city":"Millbrae","state":"CA","isRemote":false,"isActive":false,"createdAt":"2026-04-12T21:26:12.691Z","occupations":[{"code":"15-1252.00","title":"Software Developers","slug":"software-developers"},{"code":"15-1299.08","title":"Computer Systems Engineers/Architects","slug":"computer-systems-engineers-architects"},{"code":"15-1299.07","title":"Blockchain Engineers","slug":"blockchain-engineers"}],"industries":[{"code":"541512","title":"Computer Systems Design Services","slug":"computer-systems-design-services"},{"code":"541511","title":"Custom Computer Programming Services","slug":"custom-computer-programming-services"},{"code":"513210","title":"Software Publishers","slug":"software-publishers"}],"jobPosting":{"@context":"https://schema.org","@type":"JobPosting","title":"Semiotic Labs - Rust Engineer","description":"We are a team of multidisciplinary experts in artificial intelligence, cryptography, and software engineering who collaborate to build solutions for unsolved problems in web3.
