MLOps & Platform Engineer

TXT Group , a company within the TXT Group , is seeking an MLOps & Platform Engineer to join its Industrial Business Unit. The ideal candidate will be responsible to design, build and operate the company’s application and AI platform, ensuring secure, scalable and highly available environments for both enterprise applications and AI/ML workloads. At least three years’ relevant experience in platform and infrastructure engineering is required, with production ownership of: Kubernetes, CI/CD pipelines and cloud infrastructure.

Main responsibilities

• Design and manage cloud-native platforms, Kubernetes clusters and containerised applications;
• Build and maintain CI/CD pipelines, and automate infrastructure provisioning and application deployment;
• Design, deploy and manage infrastructure for AI systems: LLM and embedding model serving, vector databases, application databases and caching systems;
• Define and maintain CI/CD pipelines for AI applications and data pipelines, with reproducible environments and secure release strategies;
• Manage versioning of models, prompts and configurations, and support fine-tuning and retraining pipelines where required;
• Collaborate with software developers and AI engineers to streamline delivery and operations;
• Implement monitoring, logging, tracing and alerting for LLM applications and data pipelines, covering latency, error rate, cost per call, drift and production quality metrics;
• Ensure scalability, high availability and operational continuity of AI services, including knowledge base ingestion and update pipelines;
• Optimise inference and embedding costs through resource sizing, quantisation, batching and infrastructure-level caching;
• Ensure overall platform security, observability, performance and operational reliability;
• Manage secrets, API keys, access control and environment isolation for AI services;
• Support offline evaluation and A/B testing activities by providing the necessary infrastructure and telemetry data.

Indispensable technical skills

• Solid experience with containerisation and orchestration technologies such as Docker, Kubernetes, Helm and Docker Compose;
• Proficiency with CI/CD and DevOps tooling, including Git, GitLab and GitLab CI/CD (or equivalents such as GitHub Actions), GitOps workflows, container registries and release management practices, with automation skills in Python and Bash;
• Strong background in infrastructure automation on Linux, using Terraform and Ansible to implement Infrastructure as Code and manage virtualised environments;
• Solid understanding of networking and security fundamentals (TCP/IP, DNS), reverse proxies and ingress controllers (Nginx, Traefik), TLS/SSL, identity and access management (Keycloak, OAuth2/OpenID Connect), secrets management and IAM;
• Experience with observability stacks such as Prometheus, Grafana, Loki, OpenTelemetry, OpenSearch and Alertmanager (or an equivalent ELK-based stack), applied to production ML and LLM systems;
• Hands-on experience with AI/MLOps tooling, including MLflow and experiment tracking platforms such as Weights & Biases, model registries, and model serving frameworks such as vLLM, Ollama, Triton Inference Server, SageMaker or Vertex AI, applied to GPU-based inference workloads;
• Experience deploying and operating vector databases (Qdrant, pgvector), embedding models and RAG pipelines as part of production AI inference services;
• Proficiency in backend and data technologies, including Python, FastAPI and REST APIs, together with operational experience running PostgreSQL, Microsoft SQL Server and Redis in production;
• Practical experience operating production databases across SQL/NoSQL and vector stores, covering provisioning, backup and scaling;
• Familiarity with LLMOps practices, including prompt and experiment tracking, inference cost monitoring and model version management;
• Understanding of inference optimisation techniques such as quantisation, batching, caching and GPU-level optimisation (e.g. TensorRT);
• Experience managing the ML/LLM model lifecycle, including fine-tuning and retraining pipelines, offline evaluation and A/B testing;
• Working knowledge of at least one major cloud platform (Microsoft Azure, AWS or Google Cloud Platform) and its services for ML/AI workloads.

Familiarity with HashiCorp Nomad is a PLUS.
