Cloud Technical Architect

Role: Cloud Technical Architect Location: Remote Position Type : Contract Job Description • 8+ Years hands-on experience in product development, particularly in design and coding using C++ and Python for cloud-based technologies. • Experience in NMS (Network Management Systems) and telecommunications or networking domain is highly desirable. • Experience in Kubernetes ecosystem & Cloud-native application design • Experience with cloud platforms and networking on cloud and Kubernetes services (logging, resource sharing, etc.) • Experience in Scalable system architecture design and Microservices architecture • Experience in Information modelling aligned with standards (SysML, UML) • Experience with at least one of the databases: PostgreSQL, NoSQL (MongoDB), TimescaleDB, CortexDB • Experience in Elastic Search and Visualization tools: Kibana, Grafana • Experience in Languages: C++, Python, Java, JavaScript, SQL • Experience in API design: REST, gRPC, GraphQL Key Responsibilities • build an information model, aligned with element management standards and specifications, that represents the system functionality via which an operator shall be able to manage and control his network. • build a scalable system architecture of the Network Management System using cloud native components and micro services architecture. • collaborate with specialists and architects covering different technology domains. • contribute to an NMS application architecture for configuration management of the network elements and functions • contribute to an NMS application architecture for receiving events, notifications, statistics collection from the different network elements and functions. • collaborate with the development teams to ensure the defined system architecture is implementable, inclusive of effort estimation and test strategy. • collaborate with other system architects and development teams to work on proof of concepts and early evaluation. Other key responsibilities and job functions include: • Ability to communicate clearly and concisely, both orally and in writing • Ability to distill and present information to the larger organization. • Knowledge of model driven system architecture and engineering methodologies with a knowledge of SysML and UML is a big plus. What are the Optional skills and skill proficiencies for this position? • You hold a master's degree in engineering or computer science with 5+ years of experience in most of the areas below. You have experience with the Web Application Architectures and distributed system design. • As a Network Management Architect, you have the following expertise: • Thorough understanding of building a consistent Information Model representing a complex system • Knowledge of modeling languages like UML, SysML is an asset Broad software background and expertise, covering distributed application architectures • Experience with software development methodologies and associated programming languages is important • Experience in designing for scale and high availability. • Knowledge and thorough understanding of programming languages like Python, Java, Javascript, C++, SQL is an asset • Thorough understanding of databases like Timescale DB (or any Time Series DB), PostgreSQL, NoSQL (like MongoDB), Cortex DB. • Experience and understanding of Cloud Native application development best practices, knowledge of micro-services. • Experience in Kubernetes, Cloud platforms, networking on cloud platforms and Kubernetes ecosystem. • Experience in data collection pipeline- data extraction, transformation, and integration. • Experience in log collection systems like Loki, Logstash and visualization systems like Kibana, Grafana. • Experience is designing using REST, gRPC and GraphQL. Knowledge about telecom management systems and network management systems (FCAPS & OAM is desired) • Understanding of network management protocols or generic communication protocols like SNMP/MIB, NetConf/YANG, REST (OpenAPI) or GraphQL is an asset • Knowledge of telecom management standards provided by TM-Forum, ITU-T, O-RAN, 3gPP or ONF is a plus • Understanding of security concepts is key (Authentication, Authorization- Role Based Access Control) • Experience with open source or commercial management systems is a plus CONIDERATIONS FOR SCREENING Client primarily focuses on three areas: • Network Management System (NMS) • Cloud-native design • Security The NMS encompasses OAM (Operations, Administration, and Maintenance), which broadly includes the following functionalities: • Configuration management • Fault management • Event management • Statistics collection and management • IAM / user management / multi-tenancy • Change set management • Northbound API • Log management • Web UI • Secure communication, storage, and access control • Support for managing 100k+ terminals These functionalities are implemented using a cloud-native design, deployed on a cloud platform, and leverage technologies such as: • Databases for configuration and observables (e.g., Postgres, Cortex / time-series databases) • Log storage mechanisms (e.g., Loki) • OpenTelemetry pipeline • File stores like S3 • Grafana • Alertmanager • Stealth • Prometheus • Fluentd • Vector • etcd • Kubernetes (K8s) • Red Hat OpenShift • CEPH • Underlay/overlay networking for cluster-wide communication • Service discovery • Karma • Kafka • Syncope / OpenFGA / Keycloak • Webhooks • REST / GraphQL • YAML • Database synchronization techniques • Pods • Containers (can be designed using C++, Python, Golang, etc.) • Sidecars • Syslogs • Etc. Additionally, OAM functions are designed using data modeling principles and standards-compliant messaging formats for faults, statistics, and events. Awareness of OAM in mobile telecommunication standards (e.g., NETCONF/YANG) is helpful in designing OAM solutions for Satcom. The design principles are similar. The NMS is used to manage the Satcom data path and ground system. A parallel in mobile telecom would be the EMS (Element Management System) for 5G/LTE RAN. So, someone who has worked in EMS is a viable candidate. Awareness to 5g/LTE helps in understanding Satcom and hence the reference. Client team’s future development focus is on building a data analytics platform. All the above reflects what Client is currently focusing on. Client current architecture aligns with this 1:1.
