Senior Blockchain Engineer

Join the Synthetix Core Contributor community as a Senior Solidity Engineer and help build the future of DeFi.

Synthetix is a decentralized derivatives liquidity protocol built on Ethereum, with over $1B in supporting collateral the project is one of the largest in all of DeFi. The Synthetix protocol powers the use of synthetic assets (Synths) in projects across its native interfaces as well as third-party platforms like 1inch and Curve, generating $100M+ in weekly exchange volume. We are a global community of stakeholders across many functions, working together to innovate how value is transferred on the internet.

Synthetix is looking for a software engineer with extensive experience writing, testing, deploying and refining Ethereum smart contract code on mainnet, been through professional code audits and who is up to date on the current developments in Solidity and the EVM. The candidate needs to know Solidity intimately, have an informed opinion on the latest developer tooling, adhere to industry best practices and follow the latest vulnerabilities and hacks in the Ethereum smart contract space with interest.

The current team is globally distributed with contributors in Australia, North and South America, Europe and Asia. The candidate will be working most closely with the team in the Americas, and as such we are primarily looking for someone who can work on an ET or PT-friendly timezone.

We’re a small team driven by startup values - we iterate fast, test often and automate wherever possible; it’s that agility that has helped us get to where we are. We have some of the most complex Solidity contracts on mainnet managing nearly $2B+ in value and are constantly making improvements. We have upgradeable proxy contracts, an automated custom deploy process that includes all of our dApps and tooling, extensive CI, a debt pool that spans L1 and L2 (on Optimism) and over 80 contract sources to manage. Moreover, we’re in the process of migrating the protocol to v3 with a team operating in parallel.
