About KriptoK

KriptoK is building a next-generation non-custodial multichain wallet for direct-to-consumer blockchain adoption. Our mission is to make onchain finance simple, secure, and accessible for users across high-growth markets.

We support and are expanding across major ecosystems including Bitcoin, Ethereum, Solana, Sui, BNB Chain, Base, Arbitrum, Tron, HyperEVM, Avalanche, and more. From swaps and dApps to tokenized assets, vaults, and new onchain products, KriptoK is building at the frontier of consumer crypto.

We are looking for a Cryptography Expert to help coordinate and strengthen our cryptography, smart contract review, audit, and technical risk workstreams as we scale.

What you’ll work on

• Coordinate cryptography, smart contract review, and audit-related workstreams across internal and external teams.
• Work with engineering, product, and external audit partners to review wallet flows, transaction signing, protocol integrations, and smart contract interactions.
• Help assess technical risks around new chain integrations, dApp connections, vaults, swaps, tokenized assets, and future onchain products.
• Support audit preparation, documentation, issue tracking, remediation follow-up, and post-audit implementation.
• Review technical assumptions around key management, signatures, wallet permissions, message signing, and transaction approvals.
• Help the team evaluate new infrastructure, protocols, and partners from a cryptography and technical risk perspective.
• Turn complex cryptography and security topics into clear, practical recommendations for the product and engineering teams.

What we’re looking for

• Strong understanding of applied cryptography, wallets, digital signatures, blockchain infrastructure, and smart contract systems.
• Experience with audits, smart contract reviews, wallet infrastructure, DeFi protocols, or security-critical crypto products.
• Familiarity with EVM and non-EVM ecosystems such as Solana, Sui, Tron, Bitcoin, Avalanche, or HyperEVM.
• Ability to coordinate multiple technical stakeholders and keep audit/review processes moving.
• Clear communication style and strong attention to detail.
• Practical mindset: you should be able to separate theoretical concerns from real product risks.

Nice to have

• Experience working with external audit firms.
• Background in smart contract engineering, protocol research, cryptography, or blockchain security.
• Familiarity with MPC, passkeys, account abstraction, hardware-backed security, or advanced wallet infrastructure.
• Experience in consumer wallets, DeFi apps, exchanges, or fintech products.

Why join KriptoK

This is an opportunity to help shape the technical foundations of a fast-moving consumer blockchain company. You will work across some of the most important infrastructure layers in crypto and help bring safer, better onchain products to real users.
