high-performance, secure web applications using Python and JavaScript. + Architect and implement robust distributed systems and microservice architectures, leveraging Gang of Four (GoF) design patterns. + Develop scalable APIs and backend logic using tools libraries such as Django, Flask, or FastAPI, incorporating OWASP security best practices. + Implement secure authentication and authorization using tools and processes such as OAuth, JWT, OpenID Connect, and Role-Based Access Control (RBAC). + Design and implement event-driven architectures using Apache Kafka for real-time data streaming, asynchronous communication, and secure message passing. + Optimize data workflows and pipelines using Apache Spark for large-scale, secure data processing. + Implement and optimize Apache Iceberg tables for efficient data lake management and data security. + Ensure secure coding practices by mitigating risks such as SǪL Injection, Cross-Site Scripting (XSS), Cross- Site Request Forgery (CSRF), and Insecure Deserialization. + Troubleshoot and resolve performance, scalability, reliability, and security issues. **Ǫuality Assurance C Automated Testing** + Own and implement the complete testing lifecycle, including security testing, unit tests, integration tests, API tests, performance tests, and end-to-end (E2E) testing. + Develop, execute, and maintain automated test suites that incorporate security scanning, compliance validation, and regression prevention. + Implement Test-Driven Development (TDD) and Behavior-Driven Development (BDD) methodologies with security best practices in mind. + Write and manage test automation scripts using tools like PyTest, Jest, Mocha, Cypress, Playwright, or Selenium. + Define and execute API testing strategies using tools like Postman, Newman, or Karate to ensure secure and reliable API communication. + Conduct performance and load testing using tools like Locust, JMeter, or k6, ensuring applications handle secure traffic scaling. + Perform security vulnerability testing using tools like OWASP ZAP, Burp Suite, or SonarǪube to detect and mitigate risks. + Implement static and dynamic application security testing (SAST C DAST) in CI/CD pipelines. + Document and analyze defects, conduct root cause analysis, and drive corrective actions. **CI/CD C DevOps Integration** + Integrate security-focused automated test execution within CI/CD pipelines (Jenkins, GitHub Actions, GitLab CI/CD). + Implement shift-left testing and security strategies to catch defects and vulnerabilities earlier in the development cycle. + Continuously monitor application quality, security, and performance metrics. + Utilize containerization tools like Docker and Kubernetes while enforcing container security best practices. + Implement secrets management using HashiCorp Vault, AWS Secrets Manager, or environment-based security. + Deploy infrastructure as code (IaC) securely to automate deployments and prevent misconfigurations and vulnerabilities. **Collaboration C Leadership** + Mentor, guide, and support developers in secure coding, technical, and ǪA best practices. + Conduct secure code reviews, pair programming, and knowledge-sharing sessions to enhance team expertise. + Work closely with Product Managers, Designers, Engineers, and Developers to align engineering, ǪA, and security efforts with business objectives. + Translate business requirements into scalable, testable, and efficient technical solutions. + Foster a collaborative, inclusive, security-first, and high-performance development culture. **Requirements:** **Full-Stack Development G Distributed Systems** + Experience in building secure, responsive front-end applications using React, Angular, or Vue.js. + Proficiency in Python and JavaScript with experience in Django, Flask, or FastAPI. + Deep understanding of distributed systems, microservices, design patterns, and event-driven architecture (Kafka). + Strong expertise in secure API development, including OAuth, JWT, and OpenID Connect. + Proficiency in implementing secure authentication G authorization mechanisms. + Strong expertise in SǪL (PostgreSǪL, MySǪL) and NoSǪL (MongoDB, Cassandra) databases. + Experience writing secure code and mitigating common vulnerabilities (OWASP Top 10, CWE/SANS Top 25). + Big Data G Event-Driven Architecture + Experience with Apache Kafka for real-time event-driven architectures and asynchronous communication. + Experience with Apache Spark for distributed data processing and real-time analytics. + Knowledge of Apache Iceberg tables for schema evolution and transactional capabilities in big data environments. **Quality Assurance G Test Automation** + Expertise in automated testing frameworks such as PyTest, Jest, Mocha, Cypress, Selenium, or Playwright. + Proficiency in Test-Driven Development (TDD) and Behavior-Driven Development (BDD). + API testing experience using Postman, Newman, or Karate. + Proficiency in security testing tools like OWASP ZAP, Burp Suite, or SonarǪube. + Hands-on experience with static and dynamic application security testing (SAST G DAST). + Experience integrating security testing into CI/CD pipelines. + Performance and load testing experience with Locust, JMeter, or k6. CI/CD, DevOps G Cloud + Experience in integrating automated tests into CI/CD pipelines (Jenkins, GitHub Actions preferred, GitLab CI/CD). + Knowledge of continuous testing methodologies for deployment readiness. + Experience with Docker, Kubernetes, and cloud platforms (AWS preferred, Azure, or GCP). + Proficiency in deploying and managing scalable microservices in a cloud-native environment. + Strong knowledge of Kubernetes security, container security, and secrets management.
