About Position:

We are seeking a highly experienced Fullstack Engineer with 10+ years of expertise in building scalable, enterprise-grade applications using modern frontend, backend, cloud, and AI technologies. This role is ideal for a hands-on engineering leader who thrives in designing and developing end-to-end solutions while driving technical excellence across the full technology stack. As the senior-most individual contributor within an AI-enabled platform team, you will be responsible for architecting and delivering a unified application that consolidates multiple business workflows into a centralized, scalable, and user-friendly platform. The role demands deep expertise in React-based frontend development, Python backend services, AI-enabled engineering practices, and Azure cloud technologies. You will leverage AI-assisted development tools such as Claude AI to accelerate software delivery, improve code quality, streamline documentation, and enhance overall engineering productivity. While AI will be a key component of your development workflow, the application itself will be built using robust, scalable enterprise architectures.

• Role: Fullstack Engineer
• Location: New York OR New Jersey
• Experience: 10 to 15 Years
• Job Type: Full Time Employment

What You'll Do:

• Engineer and build the end-to-end full stack platform that unifies fragmented workflows into a centralized, scalable, and AI-enabled application experience.
• Design and implement frontend and backend components, including application shell, UI layers, APIs, and supporting services, ensuring performance, scalability, and production readiness.
• Develop and integrate workflow-driven modules such as collaboration interfaces, structured evaluation forms, and exportable artifacts for downstream usage and reuse.
• Build and manage integrations with enterprise systems, data pipelines, analytics platforms, and external data artifacts, enabling seamless interaction across structured and unstructured data sources.
• Design and implement systems that support AI-assisted workflows, enabling enriched user interactions, intelligent recommendations, and data-driven decision-making capabilities.
• Leverage Claude AI extensively as an engineering productivity accelerator-driving faster GTM through rapid prototyping, full stack development, debugging, and system design acceleration.
• Establish and scale Claude-driven development practices to enhance developer productivity, reduce delivery cycles, and improve code quality across the engineering lifecycle.
• Own full stack technical design and architecture, translating product and workflow requirements into robust, scalable, and maintainable implementations.
• Operate as a highly hands-on individual contributor, actively participating in coding, design reviews, and day-to-day engineering execution within an embedded team model.
• Ensure high engineering standards across the stack, including code quality, modular architecture, testing rigor, usability, and long-term maintainability.
• Drive execution discipline and delivery outcomes, ensuring the platform is production-grade, scalable, and aligned with rapid iteration needs enabled by AI-assisted development.

Expertise You'll Bring:

• 10+ years of software engineering experience, including 5+ years at Principal Engineer / Senior IC level building large-scale full stack platforms in enterprise environments.
• Proven experience designing and delivering end-to-end full stack systems that combine rich user interfaces, scalable backend services, and data-driven workflows.
• Demonstrated ownership of architecture and delivery for multiple large-scale platform programs with measurable impact on scalability, performance, usability, and time-to-market.
• Active hands-on engineer, currently building production-grade applications across frontend and backend, reviewing PRs, and driving engineering standards.
• Strong experience working in embedded/forward-deployed engineering models, collaborating directly with product and stakeholders to translate evolving requirements into scalable systems.
• Extensive usage of Claude AI or equivalent AI coding assistants as a core development accelerator-demonstrated impact on engineering velocity, code quality, and GTM timelines.
• Hands-on experience with cloud-native application development, including frontend hosting, backend services, and API management.
• Experience integrating with enterprise systems, data pipelines, and analytics platforms.
• Familiarity with designing systems that support AI-assisted workflows and intelligent application experiences.
• Strong understanding of CI/CD pipelines, observability, deployment models, and performance monitoring in distributed systems.
• Extensive hands-on usage of Claude AI for software development, including:
• Code generation and rapid prototyping
• Debugging and optimization
• System design exploration
• Documentation and knowledge capture
• Demonstrated ability to accelerate GTM timelines using Claude AI, reducing development cycle times while maintaining high quality.
• Experience establishing Claude-driven development workflows and best practices within engineering teams.
• Ability to balance AI-assisted development with strong engineering judgment, ensuring maintainable, production-grade code.
• Strong grounding in engineering best practices: code quality, modular architecture, testing discipline, and maintainability
• Excellent problem-solving and system design skills, with the ability to operate independently in high-ownership IC roles
• Strong communication skills, including working with product managers and stakeholders to shape technical solutions.
• Certifications relevant to full stack and cloud engineering such as Azure Solutions Expert, Azure Developer Associate, AWS / GCP equivalents, along with strong proficiency in Python.
• Demonstrated use of Claude AI (or equivalent AI coding assistants) to accelerate full stack development, driving measurable improvements in engineering productivity and development cycle times.
• Experience building enterprise-grade full stack platforms with complex workflows, integrations, and distributed system architectures, ideally in domains such as enterprise SaaS, digital platforms, or financial services.
