Role Overview:
We seek a skilled Server Administrator to manage and optimize our hybrid (cloud/on-premises) infrastructure, ensuring high availability, security, and scalability for our AI-driven SaaS platform.You’ll maintain backend systems, databases, and integrations while collaborating with DevOps and engineering teams to support seamless data flows and robust performance.

Key Responsibilities:

Infrastructure Management:

• Deploy, configure, and maintain Linux/Windows servers on AWS/Azure and on premises environments.

• Manage web servers (nginx), application servers (Gunicorn), and Python frameworks (Django, FastAPI).

• Optimize database performance for PostgreSQL, MongoDB, and Redis clusters, including replication and caching strategies.

• Ensure scalability for multi-tenant SaaS architectures and high-traffic AI/ML workloads.

Security & Compliance:

• Configure and maintain firewall policies (iptables, AWS Security Groups, Azure NSG) to restrict unauthorized access.

• Perform vulnerability assessments, patch management, and audits aligned with OWASP Top 10.

• Monitor intrusion detection systems (IDS) and implement RBAC for system/data access.

• Enforce encryption protocols for data in transit (TLS/SSL) and at rest (database/file-system encryption).

Automation & Monitoring:

• Develop automation scripts (Bash/Python) for server provisioning, updates, and backups.

• Configure monitoring tools (Prometheus, CloudWatch) for nginx, Gunicorn, and database performance (PostgreSQL query latency, Redis cache hit rates).

• Manage containerized environments (Docker/Kubernetes) and CI/CD pipelines (Jenkins, GitLab).

Disaster Recovery & Data Integrity:

• Design backup/restore strategies for PostgreSQL, MongoDB, and Redis data.

• Test failover mechanisms for databases and web servers to meet RPO/RTO targets.

• Validate data synchronization between external APIs (e.g., social media platforms) and internal systems.

Cross-Functional Collaboration:

• Partner with Test Engineers to replicate production environments for QA testing.

• Support DBAs in optimizing PostgreSQL query performance and MongoDB sharding.

• Assist developers in debugging nginx/Gunicorn configuration issues and FastAPI service deployments.

Requirements:

• 3+ years of server administration experience, including 2+ years in cloud environments (AWS/Azure).

• Proficiency in managing nginx, PostgreSQL, Redis, MongoDB, and Python-based stacks (Gunicorn, Django, FastAPI).

• Hands-on experience with Linux/Windows server management, scripting (Bash/Python), and IaC tools (Terraform, Ansible).

• Strong knowledge of firewall configuration, network security, and monitoring tools (Prometheus, Grafana).

• Expertise in backup solutions (pg_dump, MongoDB backups) and disaster recovery planning.

• Bachelor’s degree in computer science, IT, or related field.

Nice-to-Have:

• Certifications: AWS/Azure Administrator, PostgreSQL/Redis Professional, or RHCE.

• Experience with big data tools (Apache Spark, Hadoop) or AI/ML infrastructure (GPU clusters).

• Familiarity with compliance frameworks (GDPR, SOC2) or security tools (Snort, Nessus).

Why Join Us?

• Architect infrastructure for a pioneering AI/ML SaaS platform used globally.

• Solve complex challenges in hybrid cloud environments and real-time data processing.

• Master advanced tools like Kubernetes, Terraform, and AIOps platforms.

• Collaborate with cross-functional teams in a fast-paced, innovation-driven culture.

• Competitive salary and growth opportunities.
