  • Familiarity with modern AI-powered developer tools (e.g., GitHub Copilot, Cursor, Tabnine, etc.) and their application in team workflows.
  • Proven ability to identify and debug performance bottlenecks across both frontend and backend by analyzing server-level metrics (CPU, memory, I/O, logs, network latency, etc.).
  • Hands-on experience optimizing client-side performance using techniques like bundle splitting, lazy loading, and Lighthouse auditing.
  • Working knowledge of Google Analytics 4 (GA4) for measuring frontend performance and user interactions.
  • Deep understanding of REST APIs, microservices communication patterns, error handling, and API versioning.
  • Proficiency with Docker, CI/CD with Jenkins, and working knowledge of AWS services (EC2, S3, RDS, etc.).
  • Clear, maintainable coding style with experience in code reviews, testing frameworks ( Jest, React Testing Library), and technical documentation.
  • Comfortable working in cross-functional teams and independently owning complex features or refactors.
Preferred Qualification
  • Experience handling multi-region websites, performance optimization and data privacy/security standards.
  • Experience with BigQuery GA4 exports—writing queries to analyze usage trends, retention, conversion funnels, and performance issues.
  • Experience with DevOps, observability (New Relic, ELK), or system reliability practices.
  • Experience with API documentation tools like Swagger/Postman, and automated deployment pipelines.
  • Knowledge of CDNs (like Cloudflare) and internationalization/localization strategies for web apps.
What You'll Get
  • A fast-paced, tech-savvy startup environment where your work directly impacts product and business outcomes.
  • The autonomy to architect systems, make technical decisions, and see your ideas shipped to production.
  • Opportunity to work with state of the art tech, modern, performance-focused JavaScript stack.
  • Opportunity to drive cross-functional initiatives and contribute to the technical direction of the platform.
  • High ownership, real impact, and the satisfaction of building things that matter at scale
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
