Lead the design and development of new product features across a Next.js frontend and Go-based backend
Operate and evolve our GCP/Kubernetes infrastructure for scalability and reliability
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
