What you'll do
- Lead and mentor a team of Fullstack engineers, fostering a culture of quality, ownership, and continuous improvement
- Hands-on contribution to the codebase — writing production code, conducting code reviews, and setting coding standards
- Collaborate closely with Product, Design, QA and Backend teams to deliver cohesive, user-centric features
- Define and drive the Fullstack technical strategy, architecture, and roadmap
- Recruit, onboard, and grow fullstack engineering talent
- Lead by example by integrating AI-powered coding agents and automated LLM-based testing into your own daily development cycle
- Architect and build 'AI-First' UI patterns, moving beyond static dashboards to generative, prompt-driven interfaces in collaboration with the LLM Platform team
- Manage the 'Execution Gap' within the Fullstack pod, ensuring high-level product roadmaps are broken down into actionable, high-velocity engineering sprints with zero 'slippage'
- Drive 'Ruthless Prioritization' within the team to maintain a high delivery heartbeat, balancing technical debt with feature velocity
What we're looking for
- 10+ years of professional Fullstack development experience with majority of experience with modern JavaScript/TypeScript
- Deep expertise in at least one major framework (React, Angular, or Vue) and its ecosystem
- Strong understanding of HTML5, CSS3, responsive design, and cross-browser compatibility
- Experience building complex, data-heavy UIs with real-time data visualization
- Solid grasp of Fullstack performance optimization — bundle size, rendering, lazy loading, caching strategies
- Experience with state management patterns (Redux, MobX, Zustand, or similar)
- Proficiency with Fullstack testing methodologies — unit, integration, and end-to-end (Jest, Cypress, Playwright, or similar)
- Familiarity with design systems and component library development
- Experience using AI-assisted development tools (e.g., Claude Code) to boost engineering productivity
- 2+ years of experience leading or managing a Fullstack engineering team (people management) is a must
- Proven track record of mentoring engineers and conducting impactful code reviews
- Experience defining Fullstack architecture for large-scale applications
- Strong understanding of APIs, RESTful services, GraphQL, and system design
- Ability to balance technical debt management with feature delivery
- Excellent communication skills — can articulate technical decisions to both engineers and non-technical stakeholders
- Bias for shipping and iteration — you deliver incrementally and learn from real users
- Comfortable with ambiguity and rapid change in a fast-paced environment
- Thinking in terms of leverage and reuse, not one-off solutions
- Pragmatic about trade-offs between perfectionism and speed of delivery
Nice to have
- Familiarity with ad-tech, real-time bidding platforms, or high-traffic data products
- Contributions to open-source Fullstack projects or community involvement
- Experience building Fullstack interfaces for AI/ML-powered products (e.g., chatbots, recommendation engines, AI-generated content displays)
- Familiarity with LLM APIs and prompt-driven UI patterns
