Senior Site Reliability Engineer (Platform Engineering)

Location: Colombia - Medellin

Department: CX - R&D Engineering

 

Medellin, Colombia

Hybrid model (2 days per week at the office)

About the role

We’re hiring a Senior SRE for a Platform Engineering team inside NICE/LiveVox. This is a builder / owner role: you’ll design and evolve the AWS platform foundations that product engineering teams rely on to run services safely and efficiently.

This is not a ticket-queue operations job. We’re looking for someone who enjoys ambiguous problems, makes sound engineering decisions, and builds automation to reduce toil long-term.

 

What you’ll do (Key Responsibilities)

• Own platform reliability outcomes across AWS: availability, latency, resiliency, and operational readiness.
• Design and implement platform foundations (IAM, networking, compute, deployment patterns, and guardrails) that enable teams to build safely at scale.
• Build infrastructure automation using IaC (Terraform) and CI/CD workflows that improve repeatability and reduce manual work.
• Lead incident response for platform-level issues (detection → mitigation → root cause analysis → permanent fixes) and drive measurable prevention.
• Improve observability and operational maturity (metrics, logs, traces, SLOs, alert design) with a bias toward actionable signals.
• Partner with engineering teams to improve service design, deployment safety, and runtime behavior through pragmatic reviews and mentoring.
• Document and standardize platform patterns, runbooks, and decision records so the system gets easier to operate over time.

 

What we’re looking for

We’re not looking for a specific background as much as strong ownership and technical judgment. You’ll be successful here if you are comfortable being the person who says:
“Here’s the tradeoff, here’s the decision, here’s how we’ll measure if it worked.”

Minimum qualifications

• 5+ years in SRE / Platform Engineering / Infrastructure Engineering (or similar)
• Strong experience operating services in AWS in production
• Strong Linux fundamentals and troubleshooting skills (used for engineering judgment, not ticket processing)
• Experience building automation with Infrastructure as Code (Terraform strongly preferred)
• Fluency with at least one language used for automation (Python, Go, or similar)
• Clear written and verbal communication (you can explain complex operational topics without drama or vagueness)

Preferred qualifications

• Experience designing multi-account AWS environments, governance controls, and secure-by-default patterns
• Deep familiarity with Kubernetes, ECS/Fargate, or other production orchestration platforms
• Experience with SLO-based reliability, alert tuning, and reducing operational noise
• Experience mentoring engineers or leading reliability efforts across teams

 

This role is a good fit if you…

• Prefer engineering fixes over repeating manual work
• Can work with incomplete information and still make good decisions
• Enjoy building “paved roads” (platform standards) that teams can use independently
• Are curious, self-directed, and comfortable taking ownership without needing constant direction

This role is probably not a fit if you…

• Want a role primarily focused on helpdesk-style support, routine ticket queues, or “keep the servers patched” operations
• Prefer clearly defined tasks over designing solutions in ambiguous situations
• Avoid cross-team collaboration, tradeoff conversations, or writing down decisions

(That’s not a judgment — it’s just not this job.)
