Proof of work

The team

Join the Institutional Engineering Team, a core group responsible for building secure, high-performance systems that safeguard digital assets for institutional and enterprise clients.

We design and deliver the next generation of crypto custody and settlement services, ensuring trust, transparency, and resilience at every layer of our platform.

Our engineers are a globally distributed, mission-driven group focused on creating new, scalable services that form the backbone of our custody infrastructure — from key management and wallet orchestration to transaction pipelines and compliance systems.

We combine deep backend expertise with a strong focus on security, reliability, and performance. The team thrives in a collaborative, transparent, and DevOps-oriented environment, where technical excellence and innovation come together to redefine how digital assets are protected and managed.

If you’re passionate about secure system design, distributed architectures, and building solutions that truly matter in the crypto ecosystem, this is where you’ll make your impact.

The opportunity

  • Collaborate with product managers, architects, and DevOps engineers to design and deliver secure, scalable, and high-performance custody solutions.

  • Build and maintain new backend microservices in TypeScript, Node.js, powering custody, staking, and wallet services.

  • Integrate with blockchain networks and external systems to support asset movements, transactions, and key management workflows.

  • Contribute to frontend applications built with React and Next.js, ensuring clear operational visibility and seamless user experience.

  • Develop event-driven systems using Kafka for real-time data processing and inter-service communication.

  • Write reusable, testable, and efficient code, maintaining high standards for performance, observability, and fault tolerance.

  • Collaborate across teams to design and optimize data models, APIs, and distributed architectures.

  • Participate in technical reviews, mentor other engineers, and take ownership of services throughout their full lifecycle — from RFCs and design to deployment and maintenance.

Skills you should HODL

  • 5+ years of professional experience in fullstack or backend engineering within high-scale, high-availability systems.

  • Expert-level proficiency in Node.js and TypeScript, with hands-on experience using NestJS or similar frameworks.

  • Deep understanding of microservices, event-driven architectures, and CQRS/DDD design patterns.

  • Proven ability to design and deliver RESTful APIs and asynchronous event-based communication systems.

  • Strong experience with SQL databases and schema design for performance and reliability.

  • Solid understanding of React and modern frontend best practices.

  • Deep knowledge of state management (React Query, Context API, custom hooks).

  • Experience with Next.js, Tailwind CSS, and component-driven architecture.

  • Hands-on experience with Docker, CI/CD, and observability tools such as Prometheus and Splunk.

  • Excellent collaboration and communication skills — capable of working effectively in distributed, cross-functional teams.

Nice to haves

  • Understanding of crypto protocols, staking mechanisms, and the broader blockchain technology ecosystem.

  • Experience with gRPC, Protocol Buffers.

  • Hands-on experience with Rust.

  • Background in financial systems, digital assets, and experience in custodial or other regulated environments

What does a React developer in web3 do?

A React developer in the context of web3 is a developer who is using the React JavaScript library to build user interfaces for decentralized applications (dApps) that run on the Ethereum blockchain

These dApps often use smart contracts to facilitate transactions and other interactions on the Ethereum network

Overall, the role of a React developer in web3 involves using your skills in React development to help build cutting-edge decentralized applications that leverage the power of the Ethereum blockchain

As a React developer in web3, some of your responsibilities might include:

  • Integrating the dApp with the Ethereum blockchain. This might involve using tools like web3.js and Ethers.js to connect to the Ethereum network and interact with smart contracts.
  • Building the user interface for a dApp using React. This could involve creating components for the various elements of the dApp, such as buttons, forms, and other input elements.
  • Implementing features that are specific to decentralized applications, such as handling cryptocurrency transactions and displaying data from the blockchain in a user-friendly way.
  • Collaborating with other members of the development team, such as blockchain engineers and designers, to ensure that the dApp functions properly and meets the needs of the end users.
