Sr. Site Reliability Engineer; SRE

SiFi is a rapidly growing B2B Fin-Tech company transforming expense management for businesses in Saudi Arabia. As a licensed EMI from the Saudi Central Bank, we empower companies with innovative tools to simplify finance management.

We are looking for a Senior Site Reliability Engineer (SRE) who will take ownership of the reliability, performance, and scalability of our production systems. You will design, automate, and operate mission-critical environments that include Kubernetes clusters, database disaster recovery, workflow orchestration, and multi-region networking.

This role suits engineers who think deeply about systems — combining infrastructure, automation, and diagnostic reasoning to drive operational excellence.

• Maintain and evolve multi-region cloud infrastructure using Terraform-based Infrastructure as Code (IaC).
• Operate and optimize Kubernetes (OKE) clusters running microservices, data pipelines, and workflow orchestration.
• Manage SQL Server backup/restore pipelines, DR testing, and performance optimization.
• Ensure high availability for .NET and Python applications hosted behind load balancers and WAF.
• Design and maintain cross-network connectivity (DRGs, LPGs, VCNs, subnets, and NSGs).

• Build and maintain a centralized orchestration platform integrated with alerting and notification systems.
• Develop self-healing, monitoring, and auto-remediation scripts for infrastructure and databases.
• Implement logging, metrics, and tracing pipelines
  .
• Automate recurring operational tasks using Python, Bash, and Power Shell to reduce manual effort and improve reliability.

• Manage Git Hub Actions and Octopus Deploy pipelines for backend and data services.
• Apply strong security principles — least privilege, network segmentation, secure credentials, and encrypted communications.
• Promote Git Ops and Infrastructure-as-Code practices to ensure repeatable and traceable deployments.
• Collaborate with developers to embed reliability and resilience into every release.

• Lead incident response, run blameless post-mortems
  , and turn findings into lasting improvements.
• Partner closely with engineering teams to drive design and code-level reliability improvements.
• Conduct capacity planning, cost optimization, and system tuning for performance and scalability.
• Mentor engineers in automation, observability, and root-cause analysis best practices.

We value engineers who:

• Approach issues systematically and validate assumptions with data.
• Treat incidents as opportunities to improve design and automation.
• Rely on metrics, logs, and tracing rather than guesswork.
• Communicate findings clear&nobreak;ly and document learnings for future reference.
• Continuously refine how problems are detected, escalated and resolved.

• 5+ years of experience in Site Reliability
  , Dev Ops
  , or Infrastructure Engineering
  .

Deep experience with:

• Solid understanding of networking, load balancing, and DNS
  .
• Proven ability to analyze incidents and automate resolution.
• Experience integrating alerting and monitoring systems with communication tools (e.g., Microsoft Teams or Slack).
• Oracle Cloud Infrastructure (OCI) (compute, networking, storage, monitoring)
• Kubernetes (OKE) — deployments, ingress controllers, autoscaling
• Microsoft SQL Server — backup/restore automation, DR planning, performance tuning
• Terraform — multi-region and cross-tenant infrastructure automation
• Python & Power Shell — automation and system scripting
