Debug and resolve complex production issues across the full stack, from application logic down to the database layer.
Provide Tier-3 technical support for critical production escalations when required.
Debug complex production issues across various layers of the stack, from the application level down to database.

Required Skills & Qualifications

5-6 years of professional experience with C++ (familiarity with modern standards like C++17/20 is a plus).
3–4 years of practical experience with Python, SQL, and Perl for system automation and data manipulation.
Proven experience with containerized application development (Docker/Kubernetes) within AWS, GCP, or Azure.
Solid understanding of CI/CD pipelines and IaC tools such as Terraform or CloudFormation.
A proactive interest in leveraging AI Agents and LLM-based tools (e.g., GitHub Copilot, Cursor) to accelerate development speed and automate routine tasks.
A self-starter with excellent communication skills, capable of working independently in a fast-paced, dedicated team environment.
University degree in Computer Science, Information Technology, or a related field.

Nice to haves:

Ability to work in a flexible environment and interest in continuous process improvement
Sense of organization, focus, persistence and ability to work according to an established plan and deadline
Excellent interpersonal skills and team player
Ability to manage multiple tasks and deadlines
Imagination and creativity in developing solutions
