ABOUT THE OPPORTUNITY

We are looking for a Senior Platform Reliability Engineer to join a leading European telecommunications operator. You will help keep large-scale, business-critical production platforms reliable, observable and secure.

PROJECT & CONTEXT

• Industry: Telecommunications, with high-traffic, high-availability production systems at scale
• Focus: Reliability of Kubernetes-based platforms, observability, incident response and automation
• Team setup: Close collaboration with engineering, operations and support teams. You will build tools and documentation that operations and support teams use day to day
• Work model: Hybrid, 2 days per week at the Porto office
• Location: Candidates must be based in Porto (any nationality)
• Language: English B2 (Upper Intermediate) minimum, for daily communication in an international environment

WHAT WE'RE LOOKING FOR (Required)

• 5+ years of professional experience in SRE, DevOps, Platform Engineering or Backend Engineering, including time operating production systems at scale
• Strong Linux fundamentals and confidence on the command line
• Hands-on production experience with Kubernetes, covering workloads, networking, RBAC, observability and troubleshooting
• Scripting and automation in Python, Go or a similar language
• Solid grasp of distributed systems, including APIs, messaging, caching, latency, throughput and failure modes
• Production experience with at least one major datastore, and an understanding of how data affects reliability
• Networking and security fundamentals, including TCP/IP, HTTP, DNS, TLS, firewalls, reverse proxies and identity
• Experience designing useful observability (metrics, logs, tracing, alerting)
• Experience contributing to incident response and blameless postmortems
• Experience working alongside operations or support teams
• English B2 (Upper Intermediate) or higher

NICE TO HAVE (Preferred)

• Background in telecommunications or other high-availability, high-traffic environments
• Experience defining SLIs/SLOs and error budgets
• Experience building internal tooling and runbooks that improve on-call and support efficiency
• Exposure to infrastructure-as-code and GitOps practices
