Sobre

• At Stack Builders, we partner with clients to build high-quality, production-ready software with clear goals, strong engineering practices, and minimal waste.
• For this engagement, we are supporting a client building AI-enabled automated cybersecurity and insurance platforms. The work focuses on turning well-defined requirements and validated prototypes into reliable, scalable SaaS systems, while shaping the next generation of automated risk analysis tools.
• We are looking for a senior full-stack engineer who can take ownership of features end-to-end and work effectively in an AI-assisted development environment.
• What You’ll Work On
• Build a production system based on an existing React prototype

Implement

• Interactive data visualizations
• Risk scoring and analysis logic
• Backend integrations and supporting pipelines
• Collaborate on evolving data models as the product matures
• Build frontend interfaces for an automated Security Operations (SOC) platform
• Integrate with backend services handling telemetry, analytics, and automated workflows
• Support systems designed for heavy background data processing in a B2B context
• Early-stage implementation based on defined product direction
• Frontend-heavy work (UI, UX, interactions) and backend-focused work (APIs, data handling, business logic)
• You will spend more time directing, reviewing, and refining than typing every line yourself
• You are expected to use AI to generate initial implementations and provide the AI with codebase context (existing patterns, schemas, conventions)
• Critically evaluate AI output for correctness, edge cases, and maintainability
• Required Experience
• Senior-level experience building SaaS applications end-to-end
• Strong proficiency in React and Python
• Experience with API design and integration, databases, and data pipelines

• Ways of Working
• You speak English fluently or at a professional level.
• Your communication is clear, organized, and assertive.
• You can work a minimum of 4 hours overlapping with the US Eastern timezone for real-time collaboration with the client.
