Catena Labs

• Build robust applications, APIs, and SDKs for secure communication • Develop efficient systems for cryptographic identity management • Design end-to-end user experiences for AI agents • Engineer systems for digital identity and reputation management • Contribute to performant backend services and scalable APIs

Role Description As a Senior Software Engineer at Catena, you will be a core contributor to the team inventing new ways for humans and AI agents to interact with financial systems. You will play a critical role in developing and iterating on our core platform, including the Agent Commerce Kit (ACK), building the applications, APIs, and SDKs that facilitate secure, reliable global commerce for a new, agent-driven economy. This is an opportunity to solve novel technical challenges at the intersection of AI and finance. You will work in a highly collaborative environment, shipping code that directly impacts our product and helps define the future of how autonomous agents transact. What You'll Do - Build Agent Interaction Layers: - Develop robust applications, APIs, and SDKs that enable secure communication, collaboration, and transactions between AI agents and users. - Develop Core Product Experiences: - Build elegant and efficient systems to handle cryptographic identity management, payment workflows, and transaction processing within the ACK framework. - Engineer Agent-Native Financial Systems: - Design and implement end-to-end user experiences tailored for AI agents, ensuring secure and reliable financial interactions. - Create Identity and Reputation Tools: - Engineer systems that empower agents to establish digital identities, discover peers, and manage their reputations effectively. - Contribute to Scalable Infrastructure: - Build performant backend services and scalable APIs that ensure rapid and secure coordination among decentralized AI agents. Qualifications - 6+ years of full stack engineering experience, with a strong foundation in backend architecture as well as experience delivering user-facing products. - A track record of shipping complex production-quality products from initial concept to production. - Commitment to building performant, reliable, and secure systems with polished and intuitive user experiences. - Comfortable working in ambiguous environments, capable of independently designing and implementing technical solutions from the ground up. - Genuine curiosity for emerging technologies like AI agents, stablecoins, and programmable identity, with desire and self-initiative to learn and apply them. - Effectively leverage AI tools in your workflow to multiply productivity and streamline development processes. Requirements - Hands-on experience building AI-driven solutions or integrating with modern AI toolkits. - Experience in fintech, payments, or blockchain development. - Proficiency with our tech stack (e.g., Python, TypeScript, Go, React). - Contributions to relevant open-source projects. Benefits - Opportunity to work on challenging problems that have never been solved before. - Be part of the startup team that makes the AI economy possible. - Your work will directly enable millions of AI agents to participate safely in commerce, unlocking trillions in economic value and increasing prosperity around the world.

• Own the orchestration layer connecting product experiences to banking infrastructure • Establish eval frameworks that prove our agents are reliable • Stay ahead of emerging agent protocols (A2A, x402, MCP, LangGraph) and integrate where it strengthens our infrastructure • Partner closely with Product Development and Banking Core to ensure AI capabilities are deeply integrated • Hire and develop AI engineers and data scientists as the team grows
