REQUIRED SKILLS & EXPERIENCE

• 3+ years of production Go experience, including concurrency patterns and performance tuning.
• Proven delivery of smart-contract products; you can read and write Solidity confidently.
• Hands-on experience with at least one non-EVM blockchain (Cosmos, Solana, Sui, etc.).
• Practical knowledge of Kubernetes (Helm, operators) and Rancher for deployment and service

orchestration, plus CI/CD pipelines.

• Familiarity with service observability—Grafana, Prometheus, structured logging.
• Solid understanding of blockchain security fundamentals: key management, common DeFi

attack vectors, and safe coding practices.

• Clear, professional English for everyday written and spoken communication in a distributed

team.

ABOUT THE ROLE

Ankr’s Staking team is looking for a mid-level (or stronger) backend engineer to keep our liquid-staking
services rock-solid and help launch new DeFi products—CDPs, lending/borrowing markets, money
markets, and more. Most on-chain logic is in Solidity, while the backend glue is written in Go—so depth
in Go is essential.

KEY RESPONSIBILITIES

• Maintain and extend Go micro-services that power our liquid-staking protocols and upcoming

DeFi applications.

• Support and incrementally improve Solidity contracts (minimum 1 year of hands-on Solidity).
• Integrate non-EVM chains—Cosmos SDK, Solana, Sui, or similar—to broaden staking

coverage.

• Instrument services with Grafana/Prometheus dashboards and act on real-time operational

data.

• Rapidly evaluate new blockchains or protocols, learn their nuances on your own, and drive

product development around them with a high degree of autonomy.

• Apply secure-development practices: threat modeling, code reviews, collaboration with

auditors, and participation in post-mortems.
