Description:

Thoughtworks is hiring a Senior Developer (.NET + React) for its premier technology consultancy hub in Chennai. True to the company's 30-year legacy as a global driver of elite software engineering standards, this role is a hybrid of full-stack engineering, distributed systems architecture, and technical team leadership. You will not simply execute siloed tasks; instead, you will collaborate with Business Analysts, Designers, and Project Managers to translate complex business problems into production-ready software. You will champion Extreme Programming (XP) values—such as Test-Driven Development (TDD) and Pair Programming—while decomposing monolithic components into large-scale microservices, automating secure DevSecOps pipelines, and mentoring junior consultants.

Key Technologies:

.NET Core / C#, ReactJS, TypeScript, Object-Oriented Programming (OOP), Test-Driven Development (TDD), Extreme Programming (XP) / Scrum / Kanban, Microservices Architecture, Distributed Systems, CI/CD Pipelines, AWS, Docker, Kubernetes, DevSecOps Tools

Requirements:

• 5+ years of verified commercial software development experience shipping enterprise-grade, clean code within high-concurrency environments.
• High-level, hands-on engineering experience combining Microsoft .NET backend systems with modern React frontend frameworks, built on rigid Object-Oriented Programming (OOP) and clean architecture principles.
• Advanced conceptual and practical mastery of agile engineering methodologies, specifically Extreme Programming (XP) patterns, Pair Programming, and continuous Test-Driven Development (TDD) loops.
• Proven experience designing, building, and maintaining high-performance microservices and large-scale distributed systems running open standards.
• Extensive production-level experience containerizing application layers via Docker, configuring Kubernetes clusters, and architecting systems inside public cloud platforms (specifically AWS).
• Practical experience utilizing DevSecOps toolchains to automate continuous integration and continuous deployment (CI/CD) pipelines while shifting security practices left into the development lifecycle.
• Ability to navigate the full software delivery cycle from initial ideation, prototyping, and MVP design up to final live deployment and operational optimization.
• Demonstrated soft skills to act as a supportive technical guide for junior consultants, cultivate a healthy space for respectful design debates, and proactively monitor overall team code quality.
• Active presence in the external tech community (e.g., contributing to open-source software, writing technical blogs, or participating as a speaker at developer meetups).
