Requirements

Proven track record of building shareable frontend components and complex backend infrastructure, with a strong focus on React, TypeScript, and languages like js, Python, or Go.
Deep proficiency in AI-assisted development and a proven ability to integrate AI APIs and Vector Databases into production-grade applications.
Strong understanding of data structures, distributed systems, and database optimization (SQL/NoSQL) within high-scale environments.
Expertise in test automation and maintainable patterns, utilizing AI to enhance coverage and efficiency.
Proven ability to author technical designs for complex, multi-team projects where AI and human-written code coexist seamlessly.
Ability to communicate complex technical strategies to both technical and non-technical audiences, focusing on outcomes and user-centric design.

Responsibilities

Lead the adoption of AI-augmented development environments (e.g., Kiro, Cursor, Copilot) to accelerate the entire lifecycle, from rapid UI prototyping in React to optimizing complex backend logic.
Design and implement extensible features that unify sleek user experiences with resilient backend services and low-latency data pipelines.
Author and maintain scalable pipelines (streaming/batch) that incorporate AI-driven transformations, anomaly detection, and automated scaling to ensure data integrity from source to screen.
Serve as the go-to expert for full-stack patterns and AI literacy, coaching the team on prompt engineering, automated refactoring, and the ethical integration of AI into production code.
Drive a "shift-left" testing strategy using AI to generate comprehensive test suites (Jest, Cypress, Integration) and build AI-driven monitoring to predict and mitigate system failures.
Partner with product and design teams to align technical strategy with the project vision, ensuring that backend capabilities unlock ambitious, AI-powered frontend experiences.
Own on-call responsibilities, update runbooks, and leverage AI diagnostics to streamline incident investigation and platform stability.
