About the Role

Key Responsibilities
- Unify multi-platform user experience: Drive the migration of flagship applications onto Atlas, Kpler's component library and shared Tailwind-based design system built in Vue 3 and React.
Build platform-level microservices: Design and scale Backend-for-Frontend (BFF) layers and microservices powering maps, search, user dashboards, and preferences across web and mobile platforms.
Elevate developer experience: Empower ~20 feature teams by modernizing monorepo tooling, CI automation, migration pathways, and frontend architectural conventions.
Pioneer AI-first engineering: Integrate advanced AI development tools like Cursor and Claude Code across the engineering lifecycle to optimize workflows and boost technical velocity.
Champion architectural excellence: Architect resilient, decoupled systems leveraging hexagonal architecture, Domain-Driven Design (DDD), event-driven patterns, and micro-frontends.
Mentor and elevate engineering craft: Guide crew members through technical documentation, code reviews, frontend chapter presentations, and biweekly developer sessions.

Senior fullstack engineering experience: Proven track record of architecting, building, and operating production web applications and microservices at scale.
Core technical stack proficiency: Mastery of TypeScript across the stack, modern frontend frameworks (Vue 3, React), and backend services using Node.js.
Platform & API architecture: Deep experience with REST/GraphQL APIs, microservices, Backend-for-Frontend (BFF) patterns, and data persistence (PostgreSQL, Elasticsearch, Kafka).
Pragmatic delivery & platform mindset: Eagerness to balance high architectural quality with rapid, iterative product delivery that enables both end-users and developer teams.
AI-assisted engineering approach: Active hands-on experience utilizing AI development tools (e.g., Cursor, Claude Code) to accelerate daily engineering workflows.
