Build high-performance APIs and distributed microservices in Go + PostgreSQL, with a focus on SQL optimization and caching

Architect and deploy smart contracts (Solidity / Move) on Ethereum and Sui, with security and robustness as top priorities

Establish engineering best practices for code quality, observability, testing, and performance from the ground up

Partner closely with the founding team on product strategy, architecture, and roadmap

What We’re Looking For

Hands-on production experience with Go, Next.js, SQL optimization, and Kubernetes

Deep familiarity with PostgreSQL, Docker, GCP, NATS, and caching strategies

Strong skills in building scalable UIs, APIs, and distributed microservices

Crypto-native mindset with smart contract development experience (Solidity on Ethereum, Move on Sui)

Bonus: Strengths in performance tuning, observability, and tooling

The Ideal Mindset

You thrive in an early-stage startup environment and embrace founder-like ownership

You’re motivated to build and scale products that push the boundaries of Web3

You care deeply about quality, security, and user experience

You’re excited to help shape the technical and cultural foundation of Mojito
