• Build scalable, maintainable services that support real-time, voice-based AI interactions
• Collaborate closely with the CEO, CTO, and founding team to translate product ideas into production systems
• Analyze ambiguous or complex problems and design practical, high-impact solutions
• Move quickly from prototype to production, balancing speed and quality
• Use AI coding tools and cloud AI services as first-class tools to increase development velocity
• Continuously improve engineering practices as the company grows

Requirements

• Minimum 6 years of professional development experience
• Strong experience with Python, FastAPI, JavaScript, TypeScript, and React
• Proven ability to design full-stack systems, not just isolated features
• Experience thinking across frontend, backend, infrastructure, and testing boundaries

• Comfortable operating in fast-moving, ambiguous environments
• Effective user of AI-assisted development tools (AI IDEs, code agents, cloud AI, etc.)
• Fast learner with strong problem-solving and analytical skills
• High ownership mindset; self-directed and outcome-driven

• Docker or containerized environments
• Monitoring, logging, and testing infrastructure
• Experience scaling systems from early-stage prototypes to production
