ABOUT THE OPPORTUNITY

G2i is recruiting a Senior Full Stack Developer for Moonberg, a Zug-based intelligence lab building proprietary market intelligence and infrastructure for decentralized markets.

Moonberg processes more than 700 real-time data streams, from on-chain activity to market narratives, to generate actionable insights. Its consumer product, Obzidian, is an agentic trading terminal designed to research, monitor, and execute across markets around the clock.

We’re looking for a highly experienced engineer who can own architecture and implementation across frontend, backend, and Web3 integrations. You should be comfortable scaling data-intensive systems, solving production problems, and making technical decisions with substantial autonomy.

WHAT YOU’LL DO

– Own full stack development across React interfaces, https://jobeax.com/link/JSd7UYCSg572jJDY services, and Web3 integrations.

– Build and scale decentralized applications integrating wallets, DeFi protocols, and on-chain data.

– Integrate Web3 libraries, SDKs, packages, and APIs into reliable product workflows.

– Design systems for performance, security, scalability, and interoperability.

– Build and improve infrastructure supporting large volumes of real-time market and blockchain data.

– Investigate production issues and improve system reliability.

– Collaborate with experienced engineers on architecture and research into emerging technologies.

– Take features from technical design through implementation, deployment, and production support.

WHAT YOU’LL BRING

– 10+ years of professional software development experience.

– At least 3 years of full stack development experience with a strong Web3 focus.

– Strong proficiency in TypeScript, React, and Node.js.

– Hands-on experience shipping Web3 applications or integrations into production.

– Experience integrating wallets, DeFi services, on-chain data, and third-party Web3 packages or APIs.

– Experience designing and scaling data-intensive systems.

– Strong architectural judgment and a practical approach to performance, security, and reliability.

– Fluent English.

– The ability to work independently, communicate clearly, and take ownership in a fast-moving startup.

NICE TO HAVE

– Multi-chain development experience, ideally across both Ethereum and Solana.

– Experience with Prisma, Zod, tRPC, and Fastify.

WORKING AT MOONBERG

Moonberg operates with a fully senior team, few meetings, and a direct, execution-focused culture. Engineers have substantial ownership and are expected to move quickly while maintaining high technical standards.

The pace is demanding, and this is not a conventional 9-to-5 environment. The role suits someone comfortable with startup intensity, broad responsibility, and accountability for production outcomes.

WHAT’S OFFERED

– Fully remote work with flexible hours.

– Competitive compensation based on experience.

– Collaboration with highly experienced engineers.

– Significant technical ownership and autonomy.

– The opportunity to build core infrastructure and products in the Web3 space.

HOW TO APPLY

Apply through G2i with your resume and links to your GitHub, portfolio, or relevant projects. Please highlight your production Web3 experience and your contributions across frontend, backend, and blockchain integrations.
