About The Position

Uniphore is seeking a Principal Site Reliability Engineer to join our Platform Engineering team. This role involves writing production Go code and designing/operating cloud infrastructure. The focus is on creating services that automate runbooks, build standards, frameworks, automations, agentic workflows, and self-service capabilities to ensure enterprise-grade reliability and security. You will implement these standards in code, such as Kubernetes Operators, and collaborate with feature teams as an expert advisor. This is a senior individual-contributor role focused on large-scale, resilient, automated infrastructure, bridging software development and systems operations. The role participates in an on-call rotation and uses learnings from escalations to drive architectural fixes.

Requirements

10+ years in DevOps/SRE/Platform Engineering with demonstrated Staff- or Principal-scope impact and a track record of transforming operational models.
Production Go: regularly write Go, understand its concurrency model, and are comfortable owning Go services in production.
Kubernetes depth: operational expertise plus the ability to extend it; understand the controller-runtime model and could write or maintain a Kubernetes Operator.
Cloud & infrastructure: expert-level AWS/GCP/Azure, Terraform, and multi-cloud architecture, with strong cost-optimization instincts.
Production excellence: deep incident management, RCA process, and on-call system design experience.
Software engineering fundamentals: API design, testing, observability instrumentation, and service lifecycle ownership.
Standards & documentation: strong technical writing; create operational procedures teams can self-execute.
Architecture & planning: RFC/PRD review experience; catch operational problems at design time.
Collaboration & coaching: build team capability through tooling and knowledge transfer.

Nice To Haves

Building Kubernetes Operators, controllers, or admission webhooks (controller-runtime, kubebuilder).
Contributions to open-source infrastructure tooling.
AWS Solutions Architect Professional or equivalent GCP/Azure certifications.
Kubernetes certifications (CKA, CKAD, CKS).
Platform engineering, developer experience, or internal developer portals (Backstage, etc.).
GitOps patterns (ArgoCD, Flux) and policy-as-code tooling (OPA, Kyverno).

Responsibilities

Define and execute long-term architectural strategy for multi-cloud platforms.
Lead hands-on implementation of critical infrastructure projects focusing on reliability, automation, and performance at scale.
Own multi-year technical roadmaps for infrastructure scalability, reliability, security, and engineering velocity.
Provide technical leadership through design reviews and code contributions.
Set technical direction, eliminate architectural barriers, and drive toward simplicity.
Maintain end-to-end technical stewardship of systems, aligning execution with architectural vision and best practices.
Act as a key technical advisor to Engineering Leadership and Product Management.
Lead design reviews across Infrastructure with a focus on automation, scalability, and reliability.
Align architectural roadmaps across teams.
Partner with Security to build secure-by-default systems and remediate weaknesses.
Own the reliability of systems under technical stewardship.
Create technical clarity (vision, standards, tooling) for feature teams.
Participate in fleet-wide on-call, owning critical escalations and converting recurring failure modes into permanent architectural fixes.
Establish and evangelize design principles for reliable, secure, scalable systems.
Grow other engineers through technical mentorship, architectural guidance, and design review.
