The Role
We're looking for a Senior Cross-Chain Smart Contract Engineer to own Outposts—Shinzo's smart contract presence across blockchain ecosystems. Outposts are the access points that let builders query Shinzo data from within their chain of choice, without leaving the environment they're already working in.
This means deploying and maintaining contracts across every major ecosystem: EVM chains, Solana, Cosmos SDK chains, Move-based networks, and whatever comes next. You'll be working at the intersection of smart contract development and cross-chain messaging, building the bridges that connect blockchain builders to trustless data infrastructure.
This is early-stage, senior work. You'll be defining the architecture, prioritizing the rollout based on ecosystem size and demand, and shipping contracts that developers actually use.
What You'll Do
- Own the Outposts roadmap—defining architecture, prioritizing ecosystems, and driving execution from experimentation to production
- Build and deploy Shinzo smart contracts across blockchain ecosystems, starting with highest-impact chains
- Design cross-chain messaging integrations that pass data requests and responses between Outposts and ShinzoHub
- Collaborate closely with ShinzoHub protocol engineers to ensure seamless integration with the orchestration layer
- Adapt to each ecosystem's idioms—writing Solidity for EVM, Rust for Solana and CosmWasm, Move for Sui and Aptos, and whatever else the ecosystem demands
- Establish smart contract security practices, testing frameworks, and deployment pipelines across heterogeneous environments
- Collaborate with DevRel to translate Outposts implementations into clear integration guides for builders
What We're Looking For
Required:
- 5+ years of smart contract development with production deployments
- Deep expertise in Solidity and at least one additional smart contract language (Rust/CosmWasm, Rust/Solana, Move, or similar)
- Experience shipping contracts across multiple blockchain ecosystems, you're not single-chain
- Strong understanding of cross-chain messaging patterns (oracles, bridges, IBC, or similar)
- Security-first mindset—you think about attack vectors before you write code
- Ability to own a workstream end-to-end: architecture, implementation, testing, deployment, maintenance
Strongly Preferred:
- Experience building cross-chain messaging infrastructure (not just consuming it)
- Familiarity with Cosmos SDK and IBC
- Track record of adapting quickly to new smart contract platforms
- Contributions to open-source blockchain projects
- Experience with formal verification or advanced smart contract auditing
Bonus Points:
- You've deployed contracts on chains that didn't exist two years ago
- You believe blockchain infrastructure should deliver on the ethos—trustless, verifiable, permissionless—or it's not worth building
- You've debugged a cross-chain message that got stuck somewhere between source and destination
Tech Stack
- Protocol: ShinzoHub (EVM-compatible chain built on Cosmos SDK)
- Smart Contract Languages: Solidity, Rust (CosmWasm, Solana), Move, and expanding
- Cross-Chain: IBC, bridges, oracle networks, custom messaging
- Blockchains: Chain-agnostic—EVM, Cosmos SDK, Solana, Move-based chains, and growing
- Languages: Rust, Go, TypeScript for tooling
Why Shinzo
The Problem Is Real: Builders on every chain need access to indexed data. Today they either trust centralized APIs or build custom infrastructure. Outposts give them trustless access to Shinzo data without leaving their ecosystem.
The Scope Is Ambitious: You're not maintaining one contract on one chain. You're building Shinzo's presence across every major blockchain ecosystem—adapting to each one's constraints while maintaining consistent guarantees.
The Team Ships: We're product-led and open-source. No vaporware, no token-first development. We build working technology with developers who provide meaningful feedback, then iterate based on real usage.
You'll Own It: This is senior, autonomous work. We'll give you context and collaboration, but you're driving the Outposts roadmap.
Compensation & Benefits
- Competitive salary commensurate with experience
- Token allocation (subject to vesting)
- Remote-first with async-friendly culture
- Flexible time off
