Job Title: C#/.NET Integration Developer

Experience:4 to 9 Years

Employment Type: Full Time

Work Location: Bengaluru, India

About the Role

Youll join the team building C# connectors on existing .NET framework and integration model - each connector composed of two services plus a lightweight API touch-point, integrating with vendor vulnerability-management platforms (Qualys VMDR, Microsoft Defender VM, Rapid7

InsightVM) and writing structured data into PostgreSQL. This is hands-on product development work, not maintenance - youll be extending a live integration model with new vendor connectors.

Roles and Responsibilities

Design and build C# connector services that authenticate against vendor APIs using credentials already captured in UI/PostgreSQL credential store.

Write clean, well-tested code in an Agile environment; contribute to code reviews and development best practices.

Communicate clearly with the team on design tradeoffs, estimates, and technical risk.

Required Skills

4+ years skilled experience in C# / .NET / .NET Core, ASP.NET / ASP.NET MVC

Strong experience building and consuming RESTful/Web APIs, including third-party vendor API integrations

Solid working knowledge of PostgreSQL (or similar RDBMS) and SQL/T-SQL, including schema evolution

Experience with ADO.NET / LINQ, JSON & XML data handling





Understanding of authentication / credential-handling patterns and secure storage of secrets

Familiarity with retry/back-off patterns, pagination handling, and rate-limit management when integrating with external APIs

Experience writing Windows Console Applications and/or background services

Working knowledge of Git/TFVC and Agile delivery (JIRA or equivalent)

Strong written and spoken English; ability to work with distributed/on-site-offshore teams

Good to Have

Prior exposure to vulnerability-management platforms (Qualys, Microsoft Defender, Rapid7) or the security product domain

Experience with Azure or AWS services

Knowledge of OWASP security principles and data encryption practices

Exposure to CI/CD, unit testing, and automation practices

What Were Looking For

Someone who likes figuring out solutions against real client constraints - not just writing code to spec. You should be comfortable owning a connector end-to-end: design, build, test, and hand off, with an eye for how it fits into broader integration architecture
