Software Architect, Node.js/React, .NET and AI

We are looking for a highly skilled Software Architect with deep experience in Node.js and React, and a solid background in .NET. The ideal candidate combines strong technical capabilities with a pragmatic approach to software design and delivery, a good understanding of system architecture, and the ability to communicate effectively with both technical and non-technical stakeholders. Experience in AI tools and modern ML-based solutions is a strong plus.

Essential Job Duties

• 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.

Required Skills & Experience:

• 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.
• Experience designing reusable UI components and working with component libraries or custom design systems.
• Comfortable with front-end and back-end integration patterns and API-driven development.

Desirable Skills & Experience:

• Experience integrating Stripe or other payment processing platforms.
• Exposure to OpenAPI/Swagger for client/server code generation.
• Experience in .NET Core APIs or transitioning between monolith and microservices architectures.
• Familiarity with AI/ML concepts, tools, and frameworks (e.g., LangChain, Hugging Face, OpenAI API).
• Prior work on eCommerce, enterprise, or data-intensive applications.
• Experience with event-driven systems (e.g., RabbitMQ, Kafka).
• Familiarity with GraphQL or other modern API paradigms.

Who you are:

• 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.
• English proficiency: Upper-Intermediate (B2+) or higher across all four skills.
