Job description

We are looking for a Senior software 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) at scale. You will also leverage Puppet for configuration management and develop PowerShell-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.

How Will You Make an Impact?

  • 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 PowerShell 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.

Requirements

Python & Automation Development

  • 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 experience with Jinja2 templating - building reusable, parameterised templates for configuration and infrastructure code generation

  • Experience with pytest for unit and integration testing of automation code

Terraform & IaC Code Generation

  • Strong Terraform proficiency: module design, state management, remote backends, workspaces, and dependency graphs

  • Proven experience generating Terraform HCL programmatically using Python and Jinja2 - building template-driven pipelines that produce valid, linted, plan-ready infrastructure code

  • Familiarity with Terraform tooling: tflint, tfsec, terraform-docs, Terragrunt, or Atlantis

  • Understanding of Terraform provider internals and resource lifecycle management

Puppet & Configuration Management

  • Hands-on Puppet experience: writing manifests and modules, Hiera data hierarchies, node classification, and r10k / Code Manager workflows

  • Experience managing mixed Linux and Windows environments with Puppet at scale

  • Familiarity with puppet-lint, rspec-puppet, and automated Puppet module testing pipelines

  • Understanding of Puppet Enterprise or open-source Puppet Server administration

PowerShell Scripting

  • Proficient PowerShell scripting for Windows Server administration, task automation, and hybrid cloud integrations (AWS Tools for PowerShell, Azure PowerShell)

  • Experience writing reusable PowerShell modules, functions, and error-handling patterns

  • Familiarity with Pester for PowerShell unit testing

  • Experience automating Active Directory, Group Policy, or Windows networking tasks via PowerShell

Cloud & Infrastructure

  • Solid AWS experience: EC2, EKS/ECS, Lambda, S3, RDS, VPC, IAM, and CloudWatch - understanding of services as automation targets

  • Familiarity with CI/CD platforms and integrating infrastructure code pipelines (GitHub Actions, Jenkins, GitLab CI)

  • Comfortable working with Linux and Windows Server in production environments
