Technical Lead/Software Development Engineer III - MERN Stack

Role Overview: You are a seasoned Full Stack Developer with deep MERN stack expertise, responsible for leading technical initiatives and shaping the future of SolarSquares web applications. As a Tech Lead, you will drive architecture, scale systems to handle growing demand, and mentor engineers across levels. Your role involves 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. Key Responsibilities: - 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. Qualifications Required: - 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.
