ZKP Engineer
Kash is a social-native prediction market platform that lets users turn posts on social media into tradable predictions. Users quote-post with @kash_bot to open or join markets, with AI detecting intent, signing, and executing trades directly on the user's timeline. It serves crypto-native social media users, particularly around sports (e.g. the World Cup), crypto prices, and current events.

About Kash
Kash embeds prediction markets directly inside social media feeds, removing the need for separate apps or logins. Users create or join markets by quote-posting or replying to @kash_bot with a stance and a dollar amount; Kash's AI parses the intent, signs the transaction, and executes it on-chain automatically. Markets are AI-generated in real time from trending topics (sports events like the World Cup, crypto prices, cultural moments), and resolutions are automated and trustless, with winnings paid out in USDC and the $KASH token to self-custodial wallets. The platform also offers advanced features such as limit orders, leveraged stakes, market creation with revenue sharing, private predictions via DMs, and an AI assistant (Ask Kash) for real-time odds and stats. Kash targets everyday social media users who want a frictionless, feed-native way to bet on outcomes, and is backed by top-tier venture capital firms.
Skills
About the Role
You'll design and implement circuits for trustless market resolution, privacy-preserving proofs, and cryptographic primitives that make prediction markets provably fair. You will work closely with smart contract engineers to bring proofs onchain and contribute to the overall security architecture of the platform.
Requirements
- 3+ years working with zero-knowledge proof systems
- Strong experience with Circom, Noir, or similar DSLs
- Deep understanding of constraint systems, R1CS, and circuit optimization
- Familiarity with zkTLS, attestation protocols, or oracle design
- Solid foundation in cryptography and mathematics
- Experience with Solidity and EVM integration a plus
- Bonus: contributions to open-source ZK projects
Responsibilities
- Design and build ZK circuits for market resolution and verification
- Implement zkTLS and other proof systems for trustless data attestation
- Optimize circuit performance and proving times
- Work with smart contract engineers to integrate proofs onchain
- Research and prototype new cryptographic approaches
- Contribute to security architecture and threat modeling
