System Architect IoT & AI Solutions

System Architect

Responsibilities:

• System Architecture Design

  Architect scalable, fault-tolerant, and modular IoT-based systems integrating edge devices, field protocols, cloud infrastructure, virtualization environments, and analytics engines.

• IoT Platform Planning

  Design real-time and batch data ingestion pipelines using MQTT, Modbus TCP/RTU, REST APIs, and message brokers like Kafka or RabbitMQ.

• Server, Virtualization & Infrastructure Oversight

  Lead deployment and performance tuning of Linux-based servers. Plan and manage

  VMware-based virtualization environments

  , including vSphere, ESXi, and vCenter. Configure and monitor web servers (Nginx/Apache), optimize resource allocation, and manage virtual networking and shared storage.

• Networking & Firewall Management

  Design and implement segmented network topologies with VLANs and routing policies. Configure firewalls (e.g., pfSense, Fortinet, iptables) and manage VPNs, NAT, port forwarding, and IDS/IPS. Maintain secure LAN/WAN connectivity between IoT field devices, servers, and cloud endpoints.

• Database & Storage Design

  Architect time-series and relational/NoSQL databases (TimescaleDB, InfluxDB, PostgreSQL, MongoDB). Ensure data integrity with backup, replication, sharding, and high availability strategies.

• API & Microservices Governance

  Define RESTful API standards, service-to-service contracts, and enforce microservices architecture best practices with security and observability baked in.

• Cloud Deployment & DevOps

  Oversee hybrid deployments across on-prem, Azure, and AWS using Docker, Kubernetes, and CI/CD tools (GitLab, Jenkins, ArgoCD). Automate infrastructure as code (Terraform/Ansible) and monitor deployments for scalability and resilience.

• Security, IAM & Compliance

  Implement system-wide encryption (TLS/SSL), RBAC, IAM policies, endpoint hardening, and firewall rules. Continuously monitor for vulnerabilities and ensure compliance with industry security standards (e.g., ISO 27001, NIST).

• Monitoring & Reliability Engineering

  Set up centralized logging, health dashboards, and alerting using Prometheus, Grafana, Zabbix, and ELK stack. Design disaster recovery, failover, and high-availability mechanisms across VMs, databases, and cloud systems.

• Collaboration & Leadership

  Lead cross-functional teams (backend, frontend, AI/ML, embedded) to ensure modular and maintainable system integration. Continuously review and refine architecture through stakeholder feedback and tech evaluations.
