COMPANY

At 0x, our mission is "Create a Tokenized World Where All Forms of Value Can Flow Freely". We deliver this to web3 builders with a delightfully simple suite of developer APIs that provide faster trading, better prices, and superior user experience.

Founded in 2017, we’ve processed over 78M+ transactions and $140B+ in trading volume from users trading on Matcha, Coinbase Wallet, Robinhood Wallet, Phantom, Rainbow, DefiLlama, MetaMask, Zerion, Zapper, and many more. Our investors include Greylock Partners, Pantera Capital, and Jump Crypto.

When you join 0x, you’ll become part of a veteran team of crypto builders who know the importance of code quality, team cohesion, and a culture of learning.

The Role

Join our Liquidity Engineering team, whose mission is to maximize our pricing coverage and competitiveness to maintain our position as the best DEX aggregation engine on the planet on 20+ chains across both EVM and SVM.

We work at the frontier of liquidity sourcing, AMM modeling, and route optimization, ensuring our infrastructure is robust, fast, and always ahead of the competition. You’ll help shape the future of how tokenized value flows in DeFi : without interruptions, with high accuracy, and across the most relevant chains and markets.

Responsibilities - What you’ll do

  • Find and integrate AMMs into our existing routers for both SVM and EVM environments to maximize price competitiveness, token coverage and execution quality of our trading APIs
  • Build tools to automatically analyze DEX liquidity across 20+ chains. Identify and act on price improvement opportunities using data-driven insights and protocol knowledge
  • Balance speed and pricing to achieve the right outcomes for the business; maximize win rates within meta-aggregators, wallets, and the broader competitive landscape
  • Continuously monitor, troubleshoot, and improve our liquidity integrations to maintain top-tier performance
  • Stay ahead of trends in DEX design, evaluating and onboarding high-value opportunities
  • Accurately predict and prioritize which new DEXes will have the greatest impact on price competitiveness

Requirements - Who you are

  • 5+ years of professional software engineering experience, including 2+ years in DeFi
  • In-depth knowledge of design and mechanics of leading AMMs (constant product, concentrated liquidity, stable-swap, orderbook, etc.)
  • Comfortable coding in Rust
  • Basic working knowledge of Solidity
  • Proven ability to design systems with input from multiple stakeholders, balancing technical, product, and operational trade-offs
  • Experience modifying existing production codebases and shipping those changes without impact to system uptime
  • Experience implementing systems with high performance / latency demands
  • Self-driven and effective in a fully remote environment. A successful candidate will be able to communicate clearly and work independently while staying closely aligned with the team.
  • Knowledge and passion for decentralized finance and the 0x mission
  • Exhibit our core values : do the right thing, consistently ship, and focus on long‑term impact
  • Willingness to travel globally for two annual in‑person team meetups - all travel expenses covered
  • Preferred

  • Experience integrating onchain with major DEX protocols and aggregators (e.g., Uniswap, Curve, Balancer)
  • Familiarity with both EVM and SVM ecosystems, including chain-specific nuances : transaction lifecycle, performance optimizations and MEV dynamics
  • Experience building tools or frameworks for liquidity analysis and price competitiveness benchmarking
  • Bonus points if you're able to explain a new, complex, or unusual AMM design to us in plain English
  • BENEFITS

  • Comprehensive insurance (medical / dental / vision / life / disability) for U.S.-based employees — 100% of base plan covered for you and dependents
  • 401k and FSA for U.S.-based employees
  • Monthly mobile phone bill, wellness, and pre‑tax transportation expense
  • Covered mental health benefits (included professional therapy sessions)
  • A supportive remote environment
  • Lunch reimbursement for all employees across the globe!
  • Stipend for your ideal remote / WFH set‑up : headphones, and any other work gear you may need
  • 12‑week paid parental leave
  • Great office conveniently located in the SF Financial District for those in the region!
  • Flexible vacation : Take time when you need it (and we really mean it!)
