Job description

Ncounter is supporting the growth of a highly technical infrastructure engineering function and is looking for an experienced Infrastructure Developer who sits firmly between software engineering and large-scale infrastructure.

This is not a traditional infrastructure or operations position. You will be writing production-quality Python and building the APIs, services and automation that connect complex infrastructure environments. The wider goal is to remove manual infrastructure processes and replace them with reliable, self-service, API-driven services.

You will design and develop integrations across areas including bare-metal compute, networking, storage, cloud and workload platforms. A major part of the role will involve building API services around a central CMDB, creating a reliable source of truth that can drive automated provisioning, configuration and infrastructure lifecycle management.

Responsibilities will include:

• Building production-grade services and automation primarily in Python
• Designing REST APIs and integration layers across infrastructure platforms
• Developing CMDB services, schemas and infrastructure data models
• Creating event-driven automation workflows and self-service capabilities
• Integrating vendor and internal APIs across compute, networking, storage and cloud
• Working closely with infrastructure, platform, security and application engineering teams

We are particularly interested in engineers with:

• FastAPI, SQLAlchemy, Pydantic and PostgreSQL exposure
• Excellent REST API design and systems integration knowledge
• Experience modelling complex infrastructure or configuration data
• Knowledge across at least two areas of networking, storage, bare metal, virtualisation or cloud
• Kubernetes or cloud-native engineering experience
• A background building automation for large, complex technology environments

Experience with CMDB platforms, network automation, event-driven architectures, Terraform, Ansible or high-performance infrastructure would be valuable.

This is an opportunity for a software engineer who genuinely understands infrastructure to take ownership of complex automation problems at significant scale. Contact Ncounter to discuss the environment, technical challenges and wider opportunity in confidence.
