Senior Backend Developer

At NiCE, we don’t limit our challenges. We challenge our limits. Always. We’re ambitious. We’re game changers. And we play to win. We set the highest standards and execute beyond them. And if you’re like us, we can offer you the ultimate career opportunity that will light a fire within you.

We're looking for a Senior Backend Developer to join our Mobius team , a critical engineering group responsible for ingesting, transforming, and managing the data that powers NIA analytics. This is not a greenfield startup project. It is a highly scalable enterprise platform that sits at the center of a mature analytics ecosystem used by multiple product teams and customers worldwide.

We work with advanced technologies that include custom speech analytics, big data frameworks, and cloud deployments. Our team provides bedrock functionality for most of NiCE’s products, so you will contribute to a large, mature codebase.

This role requires genuine depth in SQL Server — you will analyze complex schemas, write and tune complex SQL, and solve hard data-layer problems as a core part of your day-to-day work, alongside solid C#/.NET backend development.

Your software development efforts will be based on the use of Anthropic AI. You will use AI to analyze requirements, implement code, and write automated test cases.

How will you make an impact?

Design and implement backend application features in C#/.NET with a strong, hands-on data-access component.

Write, optimize, and troubleshoot complex SQL being well versed in SQL Server and Postgres

Diagnose and resolve performance problems using execution plans, indexes, and diagnostic tools on both platforms

Develop and maintain software using Anthropic AI

Provide and review component-level software designs consistent with product requirements, architectural specifications, and project standards.

Implement software designs with automated unit and integration tests.

Recommend test cases to QA and Performance Test teams.

Identify refactoring ideas for legacy code.

Update user-facing product documentation for implemented features.

Respond to escalated requests for production support, including off-hours in emergency situations.

Have you got what it takes?

7+ years of software development experience

Strong C# / .NET backend development experience

4+ years of Microsoft SQL Server experience in production environments

Deep expertise in Microsoft SQL Server and Postgres

Strong T-SQL skills: stored procedures, functions, complex joins/subqueries

Ability to read and act on execution plans; identifying and fixing slow queries

Indexing strategy — knowing what to index and why

Diagnosing locking/blocking/deadlocks

Solid grasp of schema design and normalization tradeoffs

Schema design and query tuning

Differences in behavior/tooling Postgres vs. SQL Server.

Strong personal motivation to create clean, high-quality code

Experience with AI-assisted software development including Requirements analysis, System design, Code generation and refinement, and automated unit- and integration-level testing

Familiarity with REST principles and implementation

Windows application environment

You will have an advantage if you have:

Experience using AI tools throughout the software development lifecycle

Experience migrating applications from SQL Server to Postgres

Call/contact center technology development: voice, text, video

Contributions to a major open source project

Experience with asynchronous programming

Experience with both cloud and on premise deployment
