• 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).
• Candidates with prior hands-on experience in OTA updates, software distribution, device or fleet management, update orchestration, staged rollout, rollback, and production troubleshooting of distributed update systems will be given preference.
• This role requires excellent coding and debugging skills, strong documentation habits, the ability to collaborate closely with architects, and the capability to guide junior developers. Experience with Azure, , 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".

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).
• 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.
• 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.
• 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.

Software Update and Device Lifecycle Management

• Lead the design, development, and technical delivery of software update capabilities for connected devices and distributed device fleets.
• Develop and maintain workflows for software package creation, validation, assignment, distribution, installation, and update-status monitoring.
• Support staged rollouts, pilot deployments, update scheduling, version management, compatibility checks, rollback, recovery, and failure-handling mechanisms.
• Design reliable update processes that maintain device consistency and minimize service disruption during software deployment.
• Collaborate with device, platform, verification, service, cybersecurity, and DevOps teams to enable end-to-end software update integration.
• Troubleshoot complex update and deployment issues across cloud services, gateways, deployment components, and device-side software.
• Ensure update activities are traceable, auditable, secure, and aligned with applicable quality and regulatory processes.

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.
