We never post fake jobs This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network. Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

THE COMPANY Gatekeeper is a SaaS-based, next-generation Vendor & Contract Lifecycle Management platform. We help organisations reduce risk, improve compliance and maximise value. As part of our journey to becoming an AI-first company, we are embedding AI agents deeply into how Gatekeeper operates internally. These agents are not experiments; they actively support decision-making, approvals, reviews and operational workflows across the business. We’re hiring AI Platform Engineers to accelerate this transformation by working directly with teams to implement, integrate and maintain AI agents at scale. THE ROLE The AI Platform Engineer is a hands-on, execution-driven role focused on deploying AI into real business workflows. You will help shape our internal AI platform and agent frameworks and apply them inside the organisation. You will work closely with our Senior AI Platform Engineer, acting as the bridge between AI capability and day-to-day business execution. This role suits someone who is technical, pragmatic and product-minded. WHAT YOU’LL DO - Implement and deploy AI agents into internal Gatekeeper workflows. - Work directly with internal teams (Product, Marketing, Finance, Sales, Account Management, Operations, Professional Services) to understand processes and identify high-impact AI use cases. - Configure agent behaviour through prompts across different tools, rules and guardrails. - Integrate AI agents with existing systems, data sources and internal tools via APIs, webhooks and integrations. - Use Python for orchestration, data handling, light automation and evaluation. - Test, iterate and refine AI agents based on real usage and feedback. - Monitor deployed agents for accuracy, reliability and business impact, escalating issues where deeper platform changes are needed. - Collaborate with the Senior AI Platform Engineer on agent standards, tooling, observability, governance and ROI. - Document implementations and help establish repeatable internal AI deployment patterns.

• Design, implement, and deploy advanced AI capabilities within the OneAI platform. • Shape the end-user experience by designing intuitive workflows for model management, deployment configuration, and job operation. • Streamline the model lifecycle by integrating public repositories (e.g., Hugging Face) for seamless discovery, import, versioning, and deployment. • Bridge the gap between systems engineering and product design to ensure a seamless transition from backend infrastructure to user features. • Integrate cutting-edge AI frameworks and engines, such as vLLM, NVIDIA Dynamo and Unsloth, into a secure and scalable environment. • Leverage OpenNebula to orchestrate high-performance inference and training workloads across diverse cloud and edge environments. • Develop and maintain reliable APIs for compute provisioning and workload scheduling. • Implement GPU-aware operations to ensure optimal resource allocation and hardware utilization. • Build comprehensive observability suites to monitor and track critical metrics, including latency, throughput, utilization, and failure rates. • Establish and refine deployment and workflow strategies to ensure AI workloads remain efficient and stable at scale. • Optimize system architecture to balance high performance with cost efficiency. • Research and integrate emerging AI tools and engines to keep the OneAI platform at the forefront of the industry. • Analyze performance bottlenecks to iterate on the efficiency of both training and inference processes.

• Lead the design and evolution of the cloud platform across AWS and GCP • Build and standardize platform capabilities (CI/CD, observability, service templates, and golden paths) • Develop and operate shared data platform services (operators in Go, Kafka, Neo4j, and related infrastructure) • Partner with product engineering, security, and SRE teams • Mentor other engineers and drive cloud cost optimization through automation
