Blockchain is eating the world of financial services and payments. Over the next 10 years, money, payments, and banking will move to blockchain-based networks.
At Agora, we’re accelerating this transition. We’re building a global financial ecosystem enabled by this technology. One that advances financial access and opportunity, and reduces costs around sending and receiving money. We started with our flagship stablecoin, AUSD, and are building across the infrastructure and application layers to change the way the world transfers value.
Our team has deep roots in this space, and we’re looking for people who share in our mission to create a more inclusive and effective financial system. Come join us.
The Role
As our first Lead Smart Contract Engineer, you’ll architect, implement, and own the lifecycle of the Solidity contracts that power Agora’s next-generation onchain products. You’ll partner closely with the CTO and mentor junior Solidity devs while driving both greenfield protocol launches and iterative upgrades of production contracts.
What You’ll Do
- Design & architect EVM contracts from ideation to mainnet
- Implement & test contracts in Solidity using Foundry
- Own deployments across Ethereum mainnet and L2s like Optimism, Arbitrum, and
- Maintain & upgrade existing contracts: oversee proxy patterns, storage layouts, and versioned releases
- Harden security: write invariant tests, run static analyzers, coordinate external audits, and remediate findings
- Collaborate daily with frontend and product to ship end-to-end DeFi features
- Mentor & lead: set best practices for junior Solidity engineers and help shape our smart-contract roadmap
Who You Are
- 5+ years of experience as a software engineer, with 2+ years of hands-on experience architecting and deploying Solidity contracts
- Successfully launched EVM protocols through to mainnet and ensured the underlying contracts have passed third-party audits
- Deep knowledge of the Ethereum execution model, storage slots, proxy patterns, re-entrancy, and common attack vectors
- Proficiency with Foundry, RPC tooling, and CLI-based deployments
- Comfortable working across multiple L2s on bridging, chain-specific quirks, and upgrade cadence
- Strong testing culture—unit, fuzz, invariant, and property-based tests baked into CI pipelines
- Excellent written & verbal communication; you’re able to write concise specs and audit reports
- Ability to thrive in a high-ownership, fast-moving startup environment and set technical direction
How We Work
- Remote‑first; asynchronous and written communication
- Opinionated, test‑oriented development culture.
- Fast iteration cycles with continuous deployment.
- High ownership and autonomy
Why Agora
- High impact, high ownership: you’ll be the go-to architect for all on-chain logic.
- DeFi at scale: work on contracts that move real TVL across multiple chains.
- Security-first culture backed by an audit budget and time for deep testing.
- Remote-first flexibility with periodic team offsites.
