Work across the entire product lifecycle, from early prototypes to production systems. Partner closely with product, design, AI, and hardware teams to bring new experiences to life. Build integrations between software, AI systems, and connected devices. Improve reliability, performance, security, and developer experience across the stack. Make thoughtful technical decisions while balancing speed, quality, and long-term maintainability. Help define engineering culture, standards, and best practices as the team grows. Own projects end-to-end and ship quickly with a high degree of autonomy. You 4+ years of experience building and shipping production software. Strong full stack engineering skills with experience across frontend and backend development. Comfortable working across multiple parts of the stack and learning new technologies when needed. Experience building products from 0→1 or working in fast-paced startup environments. Strong product instincts and a desire to build things people actually use. Able to move quickly without sacrificing quality. Excellent problem-solving skills and attention to detail. High ownership, low ego, and strong collaboration skills. Nice to Have Experience building consumer products at scale. Experience with AI-powered products, LLMs, agents, or conversational interfaces. Experience with real-time systems, IoT, connected devices, or smart home products. Experience with React, TypeScript, Python, mobile development, or cloud infrastructure. Prior startup or founding engineer experience. Strong interest in product design and user experience. Why Join Help define an entirely new category of consumer technology. Work directly with experienced founders and an exceptional early team. Own meaningful parts of the product from day one. Build products that blend hardware, software, AI, and design. Join early enough to shape both the technology and the company. #J-18808-Ljbffr Stealth
