About the role

Commerce (the parent company of BigCommerce, Feedonomics, and Makeswift) is seeking a Backend Software Engineer II (AI Specialization) to help explore, prototype, and build product experiences using intelligent AI agents. You'll define how users interact with our products through natural language by designing agent-based systems that unify and act on data across BigCommerce, Makeswift, B2B and B2C surfaces, and partner systems. BigCommerce helps merchants of all sizes increase sales, and Makeswift enables designers and developers to build production-ready websites from live React components and a shared component ecosystem.

Responsibilities

• Design, build, and iterate on AI agents that interact with data across BigCommerce and partner ecosystems to drive automation.
• Connect agents to MCP (Model Context Protocol) servers that interact with various backend systems (APIs, databases, etc.) to surface their capabilities to the AI agents and drive powerful, intuitive user experiences.
• Build AI agents that assist with store management actions by interpreting user intent and calling the necessary APIs.
• Develop and integrate AI assistant features directly into the BigCommerce control panel to support natural language queries and actions.
• Collaborate with product designers and NLP experts to deliver intuitive, useful, and delightful conversational experiences.
• Quickly build proof-of-concept solutions to validate relevant user stories.
• Contribute to internal tooling and frameworks that support LLM fine-tuning, prompt engineering, and safe action execution.

Requirements

• 3+ years of experience in backend or full-stack software development, ideally with a focus on AI / MCP / A2A systems.
• BS or higher degree in Computer Science or a related technical field.
• Strong and proven programming skills in Go.
• Experience working with LLMs (OpenAI, Anthropic, etc.) and building agentic AI applications.
• Understanding of prompt engineering concepts.
• Understanding of RESTful APIs and data integration across systems.
• Excellent problem-solving skills and ability to work in a fast-paced, exploratory environment.
• Strong collaboration and communication skills in cross-functional teams.
• Strong preference toward execution and delivery.

Preferred qualifications

• Experience with e-commerce platforms or SaaS product development.
• Background in conversational AI or natural language processing.
• Familiarity with prompt engineering and chaining tools such as LangChain, Semantic Kernel, etc.
• Previous work with rules-based systems, automation tools, or AI copilots.
