What You’ll Do
- Architect and deliver high-performance web applications that remain responsive under heavy workloads.
- Implement front-end optimization techniques such as UI virtualization, efficient rendering, and smart state management.
- Apply asynchronous and parallel processing strategies (e.g., Web Workers or equivalent) to keep complex data workflows smooth.
- Design and maintain scalable state management solutions that balance performance with maintainability.
- Build intuitive validation and feedback mechanisms for large datasets, ensuring users get real-time visibility without performance trade-offs.
- Collaborate with product and design teams to translate business requirements into technical solutions that customers can trust.
- Document architectural decisions and communicate trade-offs effectively within the team.
- 4–7 years of professional software development experience.
- Strong proficiency in React and modern front-end practices.
- Experience designing high-performance, large-scale applications.
- Solid understanding of state management patterns (Redux or equivalent) and performanceoptimization techniques.
- Familiarity with concurrency models, asynchronous processing, and large-scale data handling.
- Knowledge of databases, RESTful APIs, and cloud deployment (AWS, GCP, or similar).
- Python and Django experience preferred but not required — the right candidate can learn quickly if already full-stack.
- Excellent communication skills and fluency in English (written and spoken).
- Comfort working in a fast-paced startup environment.
