Sense is a decentralized fixed-income protocol on Ethereum, enabling predictable returns from fixed rates and directional long/short bets on interest rates from future yield trading.
The Sense Protocol is leveraged by DeFi users who want more control over their cash flows, and it's used by fixed-income technologists who want to build new yield primitives for DeFi, such as fixed-income tokens, yield tokens, and other custom re-divisions of existing tokens' exposures.
We're working towards a future where Finance is more resilient, accessible, transparent, and fair, empowering generations of individuals with financial freedom.
Join our world-class team, backed by a diverse set of investors and mentors, including Dragonfly, Bain Capital Ventures, Variant, Nascent, Robot, theLAO, CollabCurrency, Jai Bhavnani of Waymont, Noah Zinsmeister of Uniswap, DeFi Dad, Steven Becker of UDHC, Kurt Barry of MakerDAO, and Tom Walton-Pocock.
Together, we'll embark on a mission to build decentralized permissionless infrastructure for fixed income.
~~~
We are looking for a bold, curious engineer with high standards to help us architect, implement, and test the fully permissionless, gas-optimized Sense-v2 and our next-generation fixed-rate AMM, Space-v2.
You will join a lean, highly effective team of smart contract engineers, including the CTO (Josh), and ensure consistent, high-quality codebases, technical specifications, deployment scripts, and more.
Visit our Hiring Page for more information about Sense and our culture.
Responsibilities
- Participate in technical specification design, technical roadmap, and implementation of the Sense V2 Protocol
- Create deployment scripts to enable tests, protocol configuration presets, and production deployments
- Work with auditors to ensure the quality and safety of the protocol
- Help shape the direction of systems design by defining high-level architecture, principles, and standards within DeFi
- Design processes for managing the security of the core Protocol and related applications
- Perform and assist engineers through code reviews, acceptance testing, bug fixing, and general support
Requirements
- 1+ years experience with Solidity development, from contract design to mainnet deployment
- Experience with a development suite, such as Foundry, Hardhat, Dapp, Brownie or Truffle
- Experience with contract libraries, such as Dappsys, OpenZeppelin, and Solmate
- A deep understanding of blockchain fundamentals, common vulnerabilities, and the EVM
- Know when to create abstractions vs. one-off methods
- An awareness of different products and services offered by large DeFi projects, such as Maker, Aave, and Lido, and how they are implemented in terms of business logic, technology, systems, and software architecture
- Working knowledge of the largest AMM implementation, like Uniswap, Balancer, and Curve
- A desire to keep up with emerging trends in the Ethereum and blockchain technology space
- Comfortable bridging the strategic objectives of the organization with internal engineering practices
- An understanding of how smart contract data is consumed by frontends
- Native-level fluency in English (spoken and written)
Nice to Haves
- Familiarity with the optimistic rollups, ZK rollups, and L2 bridges
- Experience writing smart contracts in languages other than Solidity as well (Rust, Vyper, etc)
- Degree in math or computer science
- A deep understanding of AMM invariants
- Experience implementing complex math in Solidity
Sense Finance is an equal opportunity employer. We value diversity at our company and do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.

What is the meaning of Layer 2?
Layer 2 in the context of cryptocurrency and blockchain technology refers to a secondary framework or protocol that is built on top of an existing blockchain system (the main chain or Layer 1)
The primary purpose of Layer 2 solutions is to solve the scalability and speed issues that many blockchains face, especially those that have become popular and heavily used, like Ethereum
Here are the key aspects of Layer 2 solutions:
- Scalability Enhancement: They help in scaling the main blockchain by handling transactions off the main chain. This reduces the burden on the main chain, allowing for faster and cheaper transactions.
- Types of Layer 2 Solutions: There are various forms of Layer 2 solutions, including state channels, sidechains, plasma chains, and rollups. Each has its own mechanism for interacting with the main chain and handling transactions.
- State Channels: These involve two parties engaging in numerous transactions outside of the main chain, which are then consolidated into a single transaction. This is especially useful for situations where multiple transactions occur between the same parties.
- Sidechains: These are separate blockchains that are connected to the main chain via a two-way peg. They operate independently and can have their own consensus mechanisms but are secured by the main chain.
- Plasma Chains: Plasma chains are similar to sidechains but with a more hierarchical structure. They report back to the main chain regularly and are optimized for mass transaction handling.
- Rollups: Rollups process and store transaction data on a sidechain but post transaction data to the main chain. They come in two varieties: optimistic rollups and zk-rollups, each with its own method of transaction verification.
- Security Considerations: While Layer 2 solutions are generally secure, they can have different security models compared to the main chain. This is an important consideration for users and developers.
- Impact on User Experience: For end-users, Layer 2 solutions can greatly improve the experience by reducing transaction fees and increasing transaction speeds.
- Adoption and Development: Many blockchain projects are actively developing Layer 2 solutions to enhance their networks. This is an ongoing area of innovation in the blockchain space.
