To support our extraordinary teams who build great products and contribute to our growth, we’re looking to add a Fullstack .Net Technical Manager – IT located in Chennai location.
We are looking for a highly experienced, hands-on Technical Lead who will play a dual role — actively contributing to coding while also mentoring and managing a small technical team.
The ideal candidate will be a strong individual contributor with deep expertise in .NET Core, React.js, containerization, and application monitoring (ELK Stack). You will lead by example — writing quality code, setting best practices, and guiding the team toward technical excellence.
This position requires strong ownership, the ability to make architectural decisions, and a collaborative mindset to work effectively with product, DevOps, and business stakeholders.

What a typical day looks like:
Lead technical design and architecture discussions ensuring scalability, performance, and security.
Design, develop, and maintain enterprise-grade web applications using .NET Core, C#, and React.js / Angular.
Act as an individual contributor — writing clean, efficient, and maintainable code while mentoring others.
Manage and guide a small team of developers — conducting code reviews, design reviews, and technical mentoring.
Own the end-to-end delivery of assigned modules — from requirements and design through deployment and monitoring.
Manage source control using Git, maintain branching strategies, and enforce best practices in version control.
Build, deploy, and manage containerized applications using Docker and Kubernetes.
Integrate and monitor systems using ELK Stack (Elasticsearch, Logstash, Kibana) for observability and troubleshooting.
Collaborate with cross-functional teams — QA, DevOps, architects, and product owners — to deliver robust solutions.
Continuously identify performance bottlenecks and propose optimizations.
Drive continuous improvement in coding practices, processes, and tools across the team.
