Software Engineer - Testing automation in Sheffield

About the Role

At Geniez AI, we're building the enterprise Generative AI framework that fundamentally changes how large organizations manage their most critical business platforms and how they build AI-powered applications to derive insights from core business data. As an early engineering hire, you'll architect and build the hybrid cloud infrastructure that powers our framework across the largest enterprise environments, with unique performance requirements, security constraints, and scale needs. This isn't about maintaining existing infrastructure. You'll be making foundational decisions about how our framework deploys, scales, and operates in enterprise environments. Your work will directly enable our largest customers to adopt and scale our solution with confidence. This role is open to candidates from the US, UK and Israel.

What You'll Build

• Test data infrastructure for automation: Build robust test data pipelines using Python, Spark and other tools that power our automated testing workflows and quality gates at enterprise scale.
• Prompt testing and evaluation: Implement and maintain robust evaluation frameworks (like LLM Evals) to automate the testing and validation of Generative AI prompt outputs and model performance.
• Hybrid cloud test environments: Design and implement our Kubernetes-native test deployment model that works seamlessly across on-prem, AWS, Azure, GCP, and hybrid environments for comprehensive testing.
• Deployment automation: Create tooling that makes deploying and upgrading our framework easy and reliable for customers with varying technical sophistication.
• Observability systems: Build monitoring, logging, and diagnostics that help both our team and customers understand system health and quickly diagnose issues.
• Internal CI/CD & testing: Evolve our internal development pipeline with automated testing frameworks, integration tests, deployment pipelines, and quality gates that let us ship confidently and frequently.

What We're Looking For

• Required:
• Python, Java, Typescript expertise: You write modern, clean, maintainable code and have shipped production systems with it.
• Kubernetes skills: Hands-on experience deploying and operating workloads on Kubernetes.
• Testing automation tools: Experience with modern testing frameworks like Playwright for robust UI automation, along with expertise in backend testing and LLM evaluation frameworks (e.g., LLM Evals).
• Quality assurance expertise: Deep understanding of building comprehensive quality gates, including integration, performance, and security testing into CI/CD pipelines.
• DevOps mindset: You think in terms of automation, reproducibility, and infrastructure-as-code.
• Systems thinking: You understand how pieces fit together, including networking, storage, security, observability and scale.
• Ownership mentality: You'll wear many hats and own outcomes, not just tasks.

Bonus Points:

• Experience testing agentic AI workflows in production at scale.
• Worked with enterprise customers on deployment/integration.
• Experience with Helm, Terraform, or similar configuration as code tools.
• Experience building enterprise software in Python, Java and Typescript.
• Understanding of enterprise security/compliance requirements (SOC2, etc.).
• Understanding of Mainframe computers and operating systems.
