Principal Full-Stack Developer – Full Time -IST
Location: Hyderabad
Job Type: Full Time
About the Role
We are seeking a Principal Full-Stack Developer to lead the design and development of scalable, secure, and cloud-native software solutions.
The primary focus of this role is full-stack software development and architecture, with strong hands-on experience across backend and frontend technologies. The ideal candidate will also have practical knowledge of cloud infrastructure and database services (Azure, AWS, or OCI) and modern software delivery practices.
DevOps is a secondary responsibility. The candidate should understand how CI/CD pipelines, how to build automation, deployments, monitoring, and release processes work, but this is not primarily an infrastructure administration role.
Key Responsibilities

Lead the architecture and development of full-stack applications.
Design scalable backend services, APIs, microservices, and distributed systems. Programming languages used may vary, though typically it is C#, Java, Python, or Node.
Build responsive and maintainable frontend applications. Technologies may vary, but React and Angular are commonly used by our clients as well as frameworks like Twitter Bootstrap, Material Design, or Tailwind.
Experience using AI Coding agents effectively is a plus, though we can also train you on the job to use these tools effectively (configuring AGENTS.md, skills, plan versus build modes, etc)
Make architectural decisions covering performance, security, scalability, and maintainability.
Develop and integrate applications using Azure, OCI, or AWS services.
Design database schemas and data-access strategies using SQL and NoSQL databases.
Review code and establish engineering standards across projects.
Guide teams in software architecture, design patterns, testing, and delivery practices.
Collaborate with product, engineering, cloud, security, and operations teams. Strong communication skills and ability to learn a customer’s business domain is a must.
Troubleshoot complex application, integration, performance, and production issues.
Contribute to CI/CD pipeline design and deployment automation. Technologies can include simple bash scripting, kubernetes/containerization, Ansible, or terraform, though we do not expect you to be an expert in all of these.
Understand and improve build, release, rollback, and environment-promotion processes.
Support observability through logging, monitoring, alerting, and application diagnostics.
Mentor senior and junior engineers.
Adapt quickly across different client domains, technology stacks, and project requirements.

Required Skills and Experience

9 + years of professional experience in software development, architecture, or related engineering roles.

Hands-on application development experience with Microsoft Azure, OCI, or AWS.
Understanding of cloud services such as compute, storage, databases, messaging, serverless, identity, networking, and monitoring.
Strong knowledge of software architecture principles, design patterns, clean code, and testing.
Experience with Git-based development workflows and code reviews.
Understanding of CI/CD concepts, including:
- Build and release pipelines
- Automated testing
- Artifact management
- Environment-specific configuration
- Deployment approvals
- Rollbacks

Experience modernizing legacy applications and migrating workloads to Azure, OCI, or AWS.
Experience with event-driven architectures and messaging platforms.
Knowledge of Kubernetes and cloud-native application patterns.
Experience with API gateways, authentication, authorization, OAuth2, and OpenID Connect.
Familiarity with Redis, MongoDB, Elasticsearch, or other NoSQL technologies.
Experience with observability tools such as Application Insights, Prometheus, Grafana, ELK, or Datadog.
Experience working with AI-assisted development or integrating AI services into business applications.
Consulting experience across multiple clients and technology stacks.
