Full-time remote
At Composable Finance, we are at the forefront of Crypto, building robust cross-chain & cross-layer infrastructure to allow the future of DeFi where almost any asset or contract can seamlessly interoperate.
Role
You’ll be building the first ZK rollup in the Polkadot ecosystem with other exciting projects like Whirlpool Cash  needing your expertise after.
As a high level blockchain developer with exposure to zero knowledge proofs, or cryptographer in the blockchain space with relevant programming skills, you’ll be working on cutting edge technology that will help shape DeFi.
Responsibilities
- Design, implement and build a ZK rollup in Polkadot ecosystem (Rust-Substrate)
- Collaborate with our team of elite level rust, cryptography and substrate experts
- Research ZK protocols and their underlying mathematical concepts.
- Study, understand and communicate the latter cryptographic primitives (e.g: signatures, NIZK, key derivation) relevant in the blockchain space.
- Produce technical specifications for designs & instantiations of cryptographic protocols
- Investigate new zero-knowledge applications im Whirlpool that allow the user to manage their deposits without compromising their privacy
- Ensure thorough project quality and securityÂ
- Write highly secure Rust code
Requirements & skills:
- Fluency in Rust, C++, Golang or similar languages, we are working primarily with Rust Substrate.
- Experience in cryptography and blockchain infrastructure developmentÂ
- Familiarity with zero-knowledge schemes (Plonk and Plonky preferred).
- Passion for Crypto/DeFi
Nice to have:
- Experience with scalability techniques such layer 2s (Optimistic and zk-based).Â
- Experience with implementing recursive zk-proofs.
- Experience with XMCP and relay-para-chain structure.
- Is interested in the Polkadot ecosystemÂ
Perks:
- Competitive Crypto payments, all made in USDC.Â
- 100% remote work. No geographic restrictions.Â
- An entrepreneurial environment that encourages innovation and facilitates the growth of cutting-edge technology.Â

- Annual personal development funding to facilitate career development
- Diversity & Inclusion: A company commitment to equal opportunity. We do not condone discrimination on the premise of race, color, religion, sexual orientation, age, gender identity or expression.
What is Zero-knowledge?
Zero-knowledge is a concept in cryptography that allows two parties to exchange information without revealing any additional information beyond what is necessary to prove a particular fact
In other words, zero-knowledge is a way of proving something without actually revealing any details about the proof
Here are some examples of zero-knowledge:
- Password authentication: When you enter your password to log into an online account, the server doesn't actually know your password. Instead, it checks to see if the hash of your password matches the stored hash in its database. This is a form of zero-knowledge because the server doesn't know your actual password, just the hash that proves you know the correct password.
- Sudoku puzzles: Suppose you want to prove to someone that you've solved a particularly difficult Sudoku puzzle. You could do this by providing them with the completed puzzle, but that would reveal how you solved it. Instead, you could use a zero-knowledge proof where you demonstrate that you know the solution without actually revealing the solution itself.
- Bitcoin transactions: In a Bitcoin transaction, you prove that you have ownership of a certain amount of Bitcoin without revealing your private key. This is done using a zero-knowledge proof called a Schnorr signature, which allows you to prove ownership of a specific transaction output without revealing the private key associated with that output.
- Secure messaging: In a secure messaging app, you can prove to your contacts that you have access to a shared secret without revealing the secret itself. This is done using a zero-knowledge proof, which allows you to prove that you have access to the secret without actually revealing what the secret is.
