About Gnosis Pay
Gnosis Pay provides the API and card-program infrastructure that enables wallets, fintechs, and businesses to issue stablecoin-powered payment cards and create custom payment flows. Partners can easily connect on-chain wallets to real-world spending.

With our technology, users can spend stablecoins directly from their on-chain wallet using a Visa debit card. Transactions are executed through a secure smart-wallet rather than a traditional bank account, allowing users to retain full custody of their assets while paying anywhere Visa is accepted.

About the role and team
We build the infrastructure that bridges traditional financial rails and crypto, enabling new financial products and seamless integrations. Our goal is to provide a secure, scalable, and developer-friendly platform that powers both internal product teams and external partners.

We are seeking a senior Go developer with hands-on experience in the card payments industry to help us take Gnosis Pay from a B2C v1 to establish a B2B2C v2. This role is a unique opportunity to shape the performance and scalability of a novel web2-web3 product that bridges self-custodial crypto assets with global Visa acceptance. You will be involved in architecture, implementation and rollout of the Gnosis Pay product to clients.

Key Responsibilities:

  • Design, develop, and deploy high-performance and scalable backend services using Go.
    Develop and maintain RESTful APIs, Formance ledger, WorkOS and processing platform integrations

  • Write clean, well-tested, and maintainable code adhering to best practices and coding standards

  • Apply Domain-Driven Design (DDD) principles to model complex business domains effectively

  • Participate actively in code reviews, providing constructive feedback to ensure code quality and consistency

  • Collaborate closely with product managers, designers, and other engineers to understand requirements and translate them into technical solutions

  • Contribute to the definition and improvement of our system architecture and engineering processes

  • Troubleshoot and resolve production issues effectively and efficiently

  • Provide guidance and support as necessary in the migration from TypeScript to Go for backend development

  • Stay up-to-date with the latest trends and technologies in Go, database systems, and software development methodologies

  • Contribute to technical documentation and knowledge sharing within the team

Who you are

  • Proven experience (6+ years) in software development with a strong focus on backend development, specifically developing and deploying high-scale, reliable services (ideally in Fintech, Payments, or high-throughput systems)

  • Proficiency in Go

  • Passion for building innovative financial products and obsession with customer experience – you advocate for what’s best for users

  • Hands-on experience integrating with and operating card scheme rails (e.g. Visa), including scheme rules, message flows, and real-world production issues around authorizations, clearing, settlement, and disputes

  • Familiarity with best practices, standards and requirements of the payments industry

  • You are excited to work at the intersection of and bridge the gaps between traditional finance and permissionless blockchain networks

What we can offer you

  • Personal Development: Pursue your professional goals with our support, including personal education budgets and conference allowances. We invest in your growth and learning.
  • Innovation and Experimentation Interested in exploring new ideas? Dedicate your Friday afternoons to research or work on a side project within our ecosystem. We encourage creativity and experimentation.
  • Flat Hierarchy: Navigate with ease in our organization. Our flat hierarchy ensures your ideas and contributions are valued and heard, without getting lost in a complex structure.
  • Flexible and Remote Work Not a morning person? No problem! We embrace flexible working schedules and have a long-standing culture of remote work. Balance your professional and personal life in a way that works for you.
  • State-of-the-Art Equipment: Receive the latest hardware and all the tools you need. We make sure you're well-equipped to do your best work.
