• Build modern frontend experiences using frameworks such as React and Next.js
• Develop backend systems and APIs using Python, Node.js, FastAPI, Django, or similar technologies
• Design data models and work across relational, graph, vector, and hybrid database architectures
• Integrate commercial APIs, open-source models, automation platforms, and third-party tools to create leverage and accelerate execution
• Build asynchronous workflows, internal dashboards, admin tools, approval systems, and automation infrastructure
• Experiment quickly across frameworks and technologies while knowing when to optimize for speed versus long-term scalability
• Contribute to shared internal libraries, Infinity Commons, and Gravity, our software factory platform
• Collaborate directly with founders, product leaders, senior engineers, and, in some cases, clients to define problems and ship solutions
• Occasionally embed with an Infinity company or client team to support launches, unblock execution, or build zero-to-one products
