Sr/Lead Developer (6-8 years)Backend and architecture

- Design, develop, and maintain enterprise applications using Java, Spring Boot, and the Spring ecosystem.

- Build scalable microservices and RESTful APIs following clean code, SOLID principles, and established design patterns.

- Design and implement authentication, authorization, and role-based access control, including SSO and external identity provider integrations.

- Develop and optimize schemas, indexes, queries, and transactions.

- Implement caching, asynchronous processing, messaging, and event-driven communication where appropriate.

- Diagnose and resolve performance issues, production defects, and complex technical problems.

Frontend

- Build and maintain frontend features using Angular and TypeScript.

- Integrate frontend applications with backend services and ensure reliable end-to-end workflows.

AI-assisted engineering

- Use AI coding agents (e.g., Claude Code, GitHub Copilot, Cursor) to accelerate design, implementation, refactoring, testing, and documentation.

- Configure and use MCP servers and connectors that give agents controlled access to repositories, issue trackers, databases, documentation, and internal tools.

- Create and maintain reusable agent assets such as project instructions, skills, prompts, and workflows for the team.

- Critically review, test, and take full ownership of AI-generated code; never ship code you do not understand.

- Ensure AI tools are used in line with data-protection and security policies, especially around clinical and patient data.

Quality and collaboration

- Write unit and integration tests and take part in code reviews.

- Contribute to application security, scalability, reliability, and maintainability.

- Work with Docker, CI/CD pipelines, Git, and containerized or cloud deployment environments.

- Collaborate with architects, product owners, QA, and DevOps throughout the SDLC.

- Mentor junior developers, including on effective and responsible use of AI coding tools, and contribute to technical documentation.

Required Skills1.

Java And Backend

Development (Primary)

- Strong Core Java: collections, streams, concurrency, exception handling, and JVM fundamentals.

- Extensive hands-on experience with Spring Boot, Spring MVC, Spring Security, Spring Data JPA, and Hibernate.





- Proven experience designing RESTful APIs and production-grade microservices.

- Solid grasp of OOP, SOLID, design patterns, and clean architecture.

- Experience with global exception handling, validation, logging, API versioning, and standardized error responses.

- Strong understanding of dependency injection, transaction management, and configuration management.

- Experience with performance tuning, debugging, and production troubleshooting.

- Understanding of distributed systems, inter-service communication, resilience, and fault tolerance.

- Security and Architecture

- Hands-on experience with Spring Security, JWT, OAuth 2.0, and OpenID Connect.

- Strong understanding of RBAC, authentication, authorization, and secure API design.

- Familiarity with API gateways, service discovery, and centralized configuration.

- Working knowledge of OWASP principles and common application vulnerabilities.

- Databases and Messaging

- Robust experience with PostgreSQL or MySQL, including schema design, indexing, and query optimization.

- Familiarity with MongoDB or other NoSQL databases.

- Knowledge of Redis or similar caching technologies.

- Experience with RabbitMQ or Apache Kafka is an advantage.

- Frontend

- Working experience with Angular and TypeScript (React experience is also considered).

- Good knowledge of JavaScript, HTML5, CSS3, and responsive UI development.

- Understanding of component-based architecture, routing, reactive forms, and state management.

- Ability to independently build and maintain frontend features when required.

- AI Coding Agents, MCP, and Connectors

- Practical, day-to-day experience using AI coding agents for real development work, not just autocomplete.

- Ability to give agents good context: clear task framing, project instructions, relevant files, and constraints.

- Understanding of the Model Context Protocol (MCP): what MCP servers, tools, and resources are,



and how agents use them.

- Experience setting up and using connectors/MCP integrations (e.g., Git hosting, Jira, databases, documentation, cloud services).

- Exposure to building a simple MCP server or tool integration (e.g., with Spring AI or an MCP SDK) is a strong plus.

- Awareness of risks in agentic workflows: prompt injection, over-broad tool permissions, secrets leakage, and sending sensitive data to external services.

- Discipline to verify AI output through tests, reviews, and reasoning before merging.

- DevOps, Cloud, and Tools

- Git and collaborative workflows (branching, merge requests, code review).

- Docker and containerized applications.

- CI/CD tools such as GitLab CI or Jenkins.

- Exposure to AWS, Azure, or another cloud platform.

- Automated testing with JUnit, Mockito, and related frameworks.

- Knowledge of monitoring, centralized logging, and deployment troubleshooting.

Preferred Qualifications

- Experience building multi-tenant SaaS or enterprise applications.

- Experience in healthcare, clinical research, clinical trial management (EDC, CTMS, ePRO), or life sciences.

- Awareness of regulated-software requirements such as audit trails, electronic signatures, 21 CFR Part 11, GxP, GDPR, or HIPAA.

- Familiarity with identity platforms such as WSO2 Identity Server, Keycloak, or Microsoft Entra ID.

- Experience with Spring Cloud, distributed caching, and event-driven architecture.

- Experience with Spring AI or integrating LLM capabilities into Java applications.

- Experience supporting production systems and resolving complex backend issues.

Experience And Education

- 6+ years of professional software development experience.

- Strong hands-on Java and Spring Boot backend experience, with production microservices delivered.

- Practical frontend experience with Angular (or React).

- Demonstrated use of AI coding agents in professional development work.

- Strong analytical, debugging, and problem-solving skills.

- Ability to own features from design through development, testing, and deployment.

- Excellent communication, collaboration, and technical decision-making
