Descripción del empleo

This position offers a leadership role in designing and building scalable full stack systems, encompassing backend services, data models, and frontend architectures that support complex, data-driven product experiences. The candidate will operate as a hands-on technical leader, influencing core services and delivering end-to-end applications that leverage AI capabilities for enterprise insight and operational efficiency.

Key Responsibilities

• Lead the design, development, and deployment of full stack applications, including backend services, APIs (REST/GraphQL), and frontend interfaces, ensuring modularity, security, and high performance.
• Collaborate with cross-functional teams Product, Design and Data Science to translate requirements into intuitive, reliable user experiences and scalable backend solutions.
• Define and evolve canonical data models, manage complex entity relationships (graphs, hierarchies), and develop indexing/search solutions (Elasticsearch, vector search) supporting AI-driven search and recommendation features.
• Build event-driven architectures (Kafka, cloud pub/sub), implementing asynchronous workflows and stream processing for scalable, real-time data handling.
• Integrate AI/ML functionalities such as retrieval-augmented generation (RAG), semantic search, and entity resolution into workflows, optimizing usability and business impact.
• Establish frontend architecture using modern frameworks (React, Vue, Angular) with focus on performance, accessibility, and shared UI component libraries.
• Drive service reliability, system observability, automated testing, and continuous improvement practices.
• Implement robust security measures, including role-based (RBAC) and attribute-based access controls (ABAC), across all layers of the application stack.
• Mentor engineering teams in architecture, code quality, and technical innovation, fostering best practices and engineering excellence.
• Coordinate with DevOps and Security to ensure compliant, scalable, and resilient infrastructure, primarily on cloud platforms like AWS.

Core Qualifications & Requirements

• 5+ years of professional full stack software engineering, with demonstrated leadership in complex enterprise systems.
• Strong expertise in backend frameworks (FastAPI, Django) and frontend frameworks (React, Vue, Angular) with modern build tools (Vite).
• Proficiency in Python and TypeScript; solid understanding of data modeling (relational, NoSQL, graph databases).
• Extensive experience designing and consuming RESTful and GraphQL APIs, with large-scale, service-oriented architecture knowledge.
• Hands-on experience with event-driven systems (Kafka, cloud pub/sub) and asynchronous processing pipelines.
• Skilled in implementing security controls (RBAC, ABAC) and multi-tenant applications, with familiarity in search technologies (Elasticsearch, vector search).
• Deep understanding of cloud-native development in AWS; CI/CD, observability, and automation practices.
• Familiarity with AI/ML feature integration, including retrieval-augmented generation (RAG), semantic search, and AI workflow observability.
