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 are looking for a
Seniorsoftware engineer
who is passionate about solving infrastructure challenges through software engineering and automation. In this role, you will design, develop, and maintain scalable automation frameworks that streamline cloud infrastructure provisioning, configuration management, and operational processes.

You will build programmatic infrastructure solutions using
Python
,
Jinja2
, and
Terraform
, generating and managing Infrastructure as Code (IaC)  will also leverage
Puppet
for configuration management and develop
Power Shell-based automation
to support and optimize Windows environments.

This is a highly technical, coding-focused position. The ideal candidate is a software-minded engineer who writes clean, maintainable, and testable code every day—not just ad hoc scripts. You should be comfortable designing reusable automation components, applying software development best practices, and driving operational excellence through automation across complex cloud and hybrid environments.

• Drive infrastructure standardization and operational excellence by designing and developing scalable automation frameworks in Python that enable consistent and repeatable deployments across cloud and on-premises environments.
• Accelerate infrastructure provisioning by building and enhancing Terraform code-generation platforms using Python and Jinja2, enabling teams to produce validated, environment-specific infrastructure code from reusable templates.
• Improve system reliability and compliance by developing and maintaining Puppet modules, manifests, and Hiera configurations that manage Linux and Windows environments at scale.
• Increase operational efficiency across Windows platforms by creating robust Power Shell automation solutions for server management, Active Directory administration, and hybrid cloud integrations.
• Simplify complex infrastructure workflows by developing internal automation tools, command-line utilities, and APIs that empower engineering teams to self-service common operational tasks.
• Enhance the speed and safety of infrastructure delivery by integrating automation frameworks with CI/CD pipelines, enabling automated validation, testing, and deployment of infrastructure changes.
• Improve software quality and reduce deployment risk by implementing comprehensive testing strategies for infrastructure code, including unit testing, linting, and integration testing.
• Partner closely with cloud, platform, and application teams to identify manual processes, eliminate operational toil, and drive automation-first solutions across the organization.
• Enable long-term scalability and maintainability by creating clear documentation, standards, and runbooks for automation frameworks and infrastructure templates.
• Contribute to a strong engineering culture by participating in code reviews, sharing best practices, and continuously improving the quality, security, and maintainability of automation solutions.

• 5+ years of Python development experience — not scripting, but structured, testable application code
• Strong understanding of Python packaging, virtual environments, dependency management (pip, Poetry), and code quality tooling (pylint, black, mypy)
• Experience building CLI tools and automation frameworks using Python (Click, Typer, or similar)
• Hands-on…
