• 10+ years of professional software development experience, with a primary focus on architecture, back-end engineering and solid full-stack capability
• Back-end:
• 7+ years of experience building scalable backend systems using Node.js and TypeScript, with frameworks like Express.js or NestJS
• 5+ years of hands-on experience with .NET (C#), preferably developing APIs or enterprise integrations using .NET Core
• Proficiency in designing and developing RESTful or gRPC services, with a solid grasp of microservice patterns and distributed architectures
• Deep experience with SQL databases (e.g., PostgreSQL, MySQL) and NoSQL systems (e.g., MongoDB, Redis)
• Working knowledge of AWS services (e.g., EC2, RDS, Lambda, S3) and container orchestration with Docker and Kubernetes
• Familiarity with CI/CD pipelines, monitoring tools, and debugging techniques for high-scale production systems
• Strong understanding of back-end fundamentals: networking, performance, observability, and security best practices
• Front-end:
• 3+ years of experience building and maintaining React applications with TypeScript
• Proficient in core web technologies: HTML, CSS, and modern JavaScript
• Familiarity with state management (e.g., react-query, Redux) and UI performance best practices

• Comfortable with front-end and back-end integration patterns and API-driven development
• Excellent communication skills – able to translate technical solutions to non-technical stakeholders
• Strong collaboration and mentoring mindset – enjoys working with others and sharing knowledge
• Curious and proactive learner, especially around new tech and architectural patterns
• Pragmatic problem-solver who prioritizes delivery and business impact over technical complexity
• Comfortable working in remote/distributed teams and agile environments

• Lead and participate in the full software development lifecycle: planning, designing, developing, testing, and maintaining scalable web applications
• Develop and maintain backend services using Node.js, with occasional work on .NET-based components
• Design and build modern SPAs using React and TypeScript with a focus on reusability and performance
• Collaborate cross-functionally with designers, product managers, and other engineers to deliver high-impact features
• Participate in architectural decisions, code reviews, and mentorship of mid- and junior-level developers
• Build and integrate scalable APIs and third-party services (e.g., Stripe, OpenAPI-based clients)
• Ensure the codebase adheres to best practices including SOLID principles, clean code, and scalable architecture
• Participate in agile development processes, including sprint planning, retrospectives, and standups
• Troubleshoot complex issues across the stack, from the browser to backend services and infrastructure
• Contribute to infrastructure decisions including CI/CD, containerization, and deployment in AWS/Kubernetes environments
• Optionally support or experiment with integrating AI-based tools into engineering workflows or product functionality
