About the role -

About the Role We’re looking for a seasoned Full Stack Developer with deep MERN stack expertise to lead technical initiatives and shape the future of SolarSquare’s web applications. As a Tech Lead, you’ll drive architecture, scale systems to handle growing demand, and mentor engineers across levels—all while collaborating with product and design teams to deliver impactful solutions in a fast-paced startup environment. If you enjoy balancing hands-on coding with technical leadership and love solving real-world challenges at scale, this role is for you.

  • Lead the design and development of complex, scalable, and high-performance web applications using the MERN stack (MongoDB, Express.js, React.js, Node.js).
  • Drive architectural decisions and establish engineering best practices for performance, maintainability, and security.
  • Own end-to-end delivery of critical projects—from planning and technical design to deployment and monitoring.
  • Champion observability and monitoring practices using tools like Prometheus, Grafana, ELK, or Datadog to ensure system reliability and proactively address bottlenecks.
  • Collaborate closely with cross-functional teams (Product, UX, QA, and DevOps) to deliver seamless, user-focused features.
  • Guide and mentor SDE1s and SDE2s, fostering a culture of technical excellence and continuous learning.
  • Define and track key engineering metrics (e.g., system uptime, latency, code quality) to drive improvements across services.
  • Maintain technical documentation and architectural diagrams for knowledge sharing and team onboarding.
  • Identify and address technical debt, scalability challenges, and opportunities for cost optimization in cloud environments.
  • Advocate for secure coding practices and ensure applications adhere to OWASP standards and data protection policies.

Requirements

  • 5–8 years of experience in full stack web development, with proven expertise in the MERN stack.
  • Proficient in JavaScript and TypeScript; strong hands-on experience with React.js, Node.js, and building RESTful APIs.
  • Deep understanding of microservices architectures, event-driven systems, and distributed computing principles.
  • Proven ability to design and scale systems handling high traffic, ensuring fault tolerance and high availability.
  • Experience with cloud platforms (AWS, Azure, or GCP), containerization (Docker), and orchestration (Kubernetes).
  • Strong knowledge of observability, monitoring, and alerting systems to maintain production-grade applications.
  • Familiarity with CI/CD pipelines, DevOps practices, and performance optimization techniques.
  • Excellent problem-solving, debugging, and system design skills.
  • Track record of mentoring engineers and leading technical discussions in Agile teams.
  • Bonus: Open-source contributions, technical blog posts, or participating in engineering meetups/conferences.
  • Bonus: Experience optimizing cloud infrastructure costs and implementing robust security practices.
