Software Engineer at ZeroNorth

We are looking for a strong, hands-on Software Engineer to own the setup, configuration, troubleshooting, and ongoing development of the replication environment across production and client instances, while also contributing to the development of internal portals and tools. This role requires a person who is equally comfortable working deep in databases and building modern web applications (ReactJS, NodeJS, .NET Core).

Key responsibilities:

• Design and develop internal programs/utilities/scripts (PowerShell, .NET, Python) to automate and manage replication activities.

• Prepare and optimize complex SQL queries for replication troubleshooting, data validation, and root-cause analysis.

• Configure, setup, and maintain ShipPalm replication for new and existing client environments.

• Perform replication health checks, conflict resolution, node registration, and channel configuration across environments.

• Monitor production replication instances proactively; identify, troubleshoot, and resolve replication issues/support requests within SLA.

• Design, develop, and maintain internal portals/tools using ReactJS, NodeJS, .NET Core, and Python.

• Build and maintain REST APIs to support internal tools, dashboards, and replication management interfaces.

• Participate in code reviews, follow secure coding practices, and maintain high code quality standards.

• Collaborate closely with onboarding, support, and infrastructure teams to ensure timely and accurate client onboarding.

• Proficient in PowerShell scripting for automation, monitoring, and deployment tasks.

• Strong analytical and debugging mindset — able to independently diagnose replication conflicts, data drift, connectivity issues, and performance bottlenecks in production environments.

• Working knowledge of Python and MongoDB is a plus; exposure to applying AI tools to improve engineering workflows is a plus.

• Comfortable owning production support responsibilities — calm under pressure, methodical in troubleshooting, and clear in communication during incidents.

• Ability to work cross-functionally with onboarding, support, QA, and infrastructure teams to drive client setup tasks to closure.

• Self-driven and capable of working with minimal supervision; strong ownership mentality from configuration through to custom tooling development.
