Job description

You'll take ownership of a new product from 0→1, partnering closely with Product and Engineering leadership to define architecture, build core features, and help shape the future of the platform.

This is a highly hands-on role for a backend-heavy full stack builder who enjoys creating products from scratch, mentoring developers, and operating with a high degree of autonomy.

This is not an AI Research or Machine Learning role. The ideal candidate is a product-minded engineer who leverages AI as a force multiplier while remaining deeply involved in backend architecture, product development, and technical leadership.

What You'll Do

• Architect and build a new AI-native product from 0→1
• Design and develop backend services using Python
• Build frontend applications using React and TypeScript
• Own technical decisions and architecture
• Design APIs, services, and scalable data models
• Contribute to AI-powered workflows, LLM integrations, and agent-based systems
• Partner closely with Product Managers on solution design and discovery
• Mentor junior developers and elevate engineering standards
• Contribute to shared platform components used across products
• Drive software quality, performance, and maintainability
• Participate in product discovery and technical planning

Who You Are

• 7+ years of software engineering experience
• Strong recent Python backend experience (Non-negotiable)
• React and TypeScript experience
• Experience building SaaS products from concept to production
• Experience building products from 0→1
• Experience owning architecture and technical decisions
• Experience building products in startup or high-growth environments
• Experience mentoring engineers
• Comfortable working with ambiguity and limited direction
• Experience with cloud-native applications, APIs, and scalable architectures
• Exposure to AI-powered products, LLMs, RAG, or agent frameworks
• Comfortable using AI development tools such as Cursor, Claude, or Copilot
• Strong ownership mentality and product mindset
