Purpose of this position / Position summary                                          

We are seeking a highly skilled and experienced Senior Full Stack Developer to join our dynamic team. The ideal candidate will have:

• Strong experience in end-to-end application development (front-end and back-end).

• Solid exposure to system design, data model design, API design, and cloud-native development practices.

• Deep hands-on expertise with modern front-end frameworks (preferably Angular and/or React) and back-end development using ".NET Core", ".NET Framework", "C#", and/or "Python".

• A strong understanding of secure-first design and OWASP guidelines, cloud security, software engineering best practices, Agile methodologies, and cloud architecture (preferably Azure).

This role requires excellent coding and debugging skills, strong documentation habits, the ability to collaborate closely with architects and technical leads, and the capability to guide junior developers. Experience with Azure, micro-frontends, microservices, cloud-native services, and the use of Generative AI tools for code and test generation is highly desirable.

Primary duties and responsibilities

Key Responsibilities

• Full Stack Application Development

  • Implement high-quality, maintainable, and efficient back-end and front-end code using ".NET Core", ".NET Framework", "C#", "Python", "Angular", and/or "React".

  • Build responsive, accessible, and cross-browser compatible UIs integrated with robust back-end services.

• System, Component & UI Architecture

  • Contribute to system and component-level design, working closely with software architects to refine and implement design patterns and technical solutions.

  • Develop reusable UI components, libraries, and patterns to ensure consistency across applications.

  • Contribute to and refine front-end architecture, including micro-frontends (e.g., module-based composition, Module Federation or similar patterns).

• Data Model Implementation

  • Implement and optimize data models in collaboration with architects and database engineers to support application performance, integrity, and scalability.

• API Development & Integration

  • Develop, document, and maintain secure, robust, and scalable APIs, ensuring adherence to established API design standards.

  • Integrate front-end applications with RESTful APIs and backend services, handling client-side state management, error handling, and performance optimization for API-heavy applications.

• Cloud-Native Development & Integration (Azure Preferred)

  • Design and build cloud-native applications, leveraging containerization, microservices, and managed cloud services.

  • Build and deploy services on Azure using Docker and Kubernetes, following cloud-native best practices (scalability, resilience, observability, and cost-efficiency).

  • Implement and integrate with Azure services (e.g., App Service, API Management, Storage, Identity, Monitoring, CDN) in line with architectural guidelines.

• Secure-First Development (OWASP & Cloud Security)

  • Apply OWASP and secure coding practices throughout the development lifecycle (e.g., XSS, CSRF, injection, authentication/authorization, secure session management) on both client and server.

  • Collaborate with security and platform teams to ensure cloud-native security (IAM, network security, secrets management, TLS, configuration hardening).

• Performance, Optimization & Quality

  • Optimize applications for speed and scalability (bundling, lazy loading, code splitting, caching, query optimization, API and database performance tuning).

  • Use profiling tools and metrics to identify and resolve performance bottlenecks on both client and server.

  • Apply solid software engineering principles, including clean code, design patterns, unit/integration/end-to-end testing, and code reviews to ensure high code quality.

• Agile Delivery & Collaboration

  • Participate actively in Agile ceremonies (daily stand-ups, sprint planning, reviews, and retrospectives).

  • Estimate work items, manage technical debt, and deliver features on time.

  • Work closely with architects, product owners, QA engineers, UX/UI designers, and other developers to clarify requirements, resolve technical issues, and deliver robust solutions.

• Documentation

  • Produce clear, concise technical documentation for modules, APIs, front-end components, patterns, and development processes to support maintainability and knowledge sharing.

  • Contribute to design systems, style guides, and coding standards for full stack development.

• Mentoring, Guidance & Knowledge Sharing

  • Provide technical guidance to junior developers, perform code reviews, and share best practices within the team.

  • Conduct technical sessions and help elevate overall full stack and cloud-native competency of the team.

• Generative & Agentic AI, Prompt Engineering (Desirable)

  • Use Generative AI tools for code scaffolding, refactoring, test generation, and documentation to improve productivity and quality.

  • Apply basic prompt engineering techniques to obtain reliable and secure outputs from AI tools.

  • Experiment with Agentic AI concepts where applicable (e.g., automating repetitive coding/testing tasks) under guidance from architects or technical leads where needed.

Education

• Bachelor’s degree in computer science or a related field.
