Descripción de la vacante

Kamino is a leading liquidity and credit engine for on-chain finance and tokenized real-world assets. This hands-on role focuses on designing, building, and hardening production-grade Solana smart contracts and developer tooling.

You will own correctness, gas efficiency, and security of core protocol contracts, and coordinate with off-chain SDKs and infrastructure to ensure robust integration.

Formación

• Experience with Rust or low-level systems programming.
• Proven track record in smart contract development with security focus.
• Ability to read, reason about, and refactor distributed systems.
• Meticulous automated testing, fuzzing, and invariants verification.
• Strong autonomy in a fast-paced, asynchronous remote environment.

Responsabilidades

• Protocol Feature Development: Design and build new protocol mechanisms within Solana contracts.
• Smart Contract Maintenance: Maintain and harden on-chain programs for efficiency and reliability.
• Security & Code Review: Conduct peer reviews, analyze audits, and implement fixes.
• Off-Chain Integrations: Coordinate contract updates with backend infrastructure and SDKs.
• AI-Native Engineering: Leverage AI tools to accelerate test coverage and code quality.

Descripción del empleo

Kamino is building the liquidity and credit engine for on-chain finance and tokenized real-world assets. As the largest credit protocol on Solana and a premier decentralized credit platform globally, Kamino has processed over $650 billion in cumulative transaction volume and originated more than $20 billion in loans. Led by former Yieldstreet co-founder Michael Weisz, Kamino is expanding institutional credit rails and asset distribution across traditional finance and decentralized markets.

Role Summary

This is a hands-on smart contract engineering role focused on designing, building, maintaining, and hardening production-grade on-chain programs and developer tooling. You will own the technical correctness, gas efficiency, and security of core protocol contracts, analyze audit findings, and integrate smart contract logic with off-chain SDKs and client services.

Key Responsibilities

• Protocol Feature Development: Design and build new protocol mechanisms and financial primitives within Solana smart contracts.

• Smart Contract Maintenance: Maintain, refactor, and harden existing on-chain programs to optimize execution and state management.

• Security & Code Review: Conduct thorough peer reviews with strict emphasis on security, correctness, and edge-case testing; analyze audit reports and implement remediation fixes.

• Off-Chain Integrations: Coordinate contract updates with backend infrastructure, client SDKs, indexing services, and developer tooling.

• AI-Native Engineering: Leverage modern AI-assisted engineering tools to accelerate test coverage, audit analysis, and code quality verification.

Requirements & Qualifications

Must-Haves

• Systems Programming: Strong production experience in Rust or low-level systems engineering (memory management, concurrency, types).

• Smart Contract Foundations: Proven track record in smart contract development (either on Solana or other major chains like EVM) with a deep focus on security-sensitive code.

• Codebase Navigation: Ability to read, reason about, and refactor complex, mission-critical distributed systems.

• Quality & Edge-Case Rigor: Meticulous approach to automated testing, fuzzing, and debugging invariants in production software.

• Autonomy: Strong problem-solving independence in a fast-paced, asynchronous remote environment.

Nice-to-Haves

• Direct production experience writing Solana programs using the Anchor framework.

• Prior domain experience in DeFi primitives (lending markets, automated vaults, DEX liquidity, or structured credit).

• Background responding to formal security audits, invariant testing, or participating in smart contract bug bounties.
