• Automate workflows and infrastructure to reduce manual effort and accelerate delivery.
• Design and maintain CI/CD pipelines for seamless, secure deployments.
• Develop and enhance observability solutions—metrics, logging, and tracing—to ensure system health and compliance.
• Define and monitor SLIs/SLOs, using data‑driven insights to improve service performance.
• Troubleshoot complex distributed systems issues and drive root cause analysis for incidents.
• Participate in incident response and post‑mortems, ensuring lessons learned translate into actionable improvements.
• Collaborate with developers on containerization and cloud‑native deployments, optimizing for resilience and scalability.
• Contribute to infrastructure‑as‑code initiatives using tools like Terraform to standardize and automate environments.
• Stay current with emerging technologies, experiment with new tools, and share knowledge with the team.
• Advocate for reliability and operational excellence across engineering teams through technical influence and collaboration.

• 5+ years of experience in SRE, Dev Ops, or related roles.
• Strong knowledge of public cloud platforms (AWS, GCP, or Azure) and Infrastructure as Code (Terraform preferred).
• Proficiency in at least one programming language (Java or Python) and scripting (e.g., Bash).
• Hands‑on experience with containers and orchestration (Docker, Kubernetes).
• Solid understanding of CI/CD pipelines and tools such as Jenkins or Git Hub Actions.
• Familiarity with observability tools (Prometheus, Grafana, ELK, etc.).
• Experience defining and monitoring SLIs/SLOs.
• Strong problem‑solving skills and ability to work in complex distributed environments.
• Excellent communication skills—able to collaborate effectively and explain technical concepts clearly.
• BS/MS in Computer Science, Engineering, or equivalent practical experience.

• Hybrid environment: a mix of working in the office and from home.
• Free food: lunch and snacks available on site when working in the office.
• Paid time off: competitive PTO package including vacation, personal days, sick leave, and charity days.
• Generous parental leave: up to 20 weeks fully paid.
