We empower brands and creators to launch digital experiences, marketplaces, and tokenized products with a seamless Web3 toolkit. Our team combines deep expertise in crypto, software, and consumer experiences, backed by top-tier investors and partners.
We’re looking for a Founding Full-Stack Engineer to join our core product team. This is a unique opportunity to own the architecture and implementation of a platform at the intersection of Web3 and consumer experiences.

- 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
