• Client: Global Technology Leader – NASDAQ Listed
• Location: Hybrid – Bristol / 3 Days Per Week
• Duration: 6 months + Intention to extend (Greenfield Multi-Year Programme)
• Day rate: £500 – Inside IR35
• Start date: ASAP

Our client, a global leader in software systems, is building AI agents that generate production .NET code under developer supervision. The goal of this greenfield is a spec-driven pipeline where a specification and technical plan drive what the agent builds, and a developer reviews and validates the output at every stage before it ships.

We are looking for a contractor who has built and shipped AI agents in production and who brings a strong .NET background. This is a hands-on engineering role with scope to set the technical direction and bring the wider team up to speed on the approach.

What you will do:

• Design and build agents that produce production-grade .NET code.
• Implement a spec-driven development workflow (spec, plan, tasks, implement), using Spec Kit.
• Build review and approval gates so developers can verify and correct agent output before it is merged.
• Integrate tools and data sources into the agents via MCP (Model Context Protocol).
• Set up evaluation, guardrails and tests to catch incorrect output early.
• Work alongside engineering team’s and upskill them on agentic patterns and the spec-driven approach.

Essential experience:

• Proven track record building and shipping AI agents in production, including tool calling, orchestration and multi-step workflows. Prototype-only experience will not be enough.
• Strong .NET and C# background (.NET 8/9, ASP.NET Core).
• Hands-on with a .NET-native agent framework, such as Microsoft Agent Framework or Semantic Kernel.
• Experience building agents whose output is code, with a clear focus on validating and verifying correctness.
• Familiarity with spec-driven development, ideally Spec Kit.
• Experience integrating tools via MCP.
• Designing human-in-the-loop review and approval gates within agent workflows.

Overview

We are looking for an AI Automation Tester to support IBM on a major programme of work

The role will focus on designing and executing automated testing across an AI-enabled solution, covering traditional functional and integration testing alongside the additional challenges involved in validating AI-generated responses and behaviours.

You’ll work as part of the wider delivery team to ensure the solution is reliable, performs as expected and continues to meet requirements as it develops.

Key Responsibilities

• Design, build and maintain automated tests across the AI solution
• Execute functional, integration and regression testing
• Develop and maintain automated test suites
• Perform API testing across integrated services
• Validate AI-generated responses and system behaviours
• Design appropriate test scenarios for AI functionality
• Manage and maintain test data required across different testing activities
• Test integrations between the AI solution and wider systems/services
• Support performance testing and identify potential issues or bottlenecks
• Analyse test results, identify defects and work with technical teams through resolution
• Support continuous testing throughout the delivery lifecycle
• Ensure appropriate regression coverage as the solution evolves
• Work closely with developers, engineers and wider delivery stakeholders

Key Skills & Experience

We’re looking for candidates with strong experience across:

• Test Automation
• API Testing
• Functional Testing
• Integration Testing
• Regression Testing
• Performance Testing
• Automated test frameworks and scripting
• Test data management
• Continuous testing / CI/CD environments
• Defect identification, investigation and management

Experience testing AI, Generative AI or LLM-based solutions would be particularly valuable, including experience evaluating the quality, consistency and accuracy of AI responses.

AI Testing

Alongside traditional automation testing, an important part of the role will be understanding how to effectively test an AI-enabled solution.

Relevant experience could include:

• AI response evaluation and validation
• Testing non-deterministic AI outputs
• Developing test scenarios and evaluation criteria for AI responses
• Testing AI APIs and integrations
• Automated evaluation of AI functionality
• Identifying unexpected, inconsistent or inappropriate model responses
• Building AI-specific testing into wider automated test suites

Candidates don’t necessarily need to come exclusively from an “AI Tester” background, but should have strong automation testing fundamentals and ideally some practical exposure to testing AI/LLM-enabled applications.

Reasonable Adjustments:

Respect and equality are core values to us. We are proud of the diverse and inclusive community we have built, and we welcome applications from people of all backgrounds and perspectives. Our success is driven by our people, united by the spirit of partnership to deliver the best resourcing solutions for our clients.
