[Remote] Senior Platform Engineer

Note: The job is a remote job and is open to candidates in USA. Tango Analytics is dedicated to helping businesses make smarter decisions through innovative technology and data-driven insights. They are seeking a Senior Platform Engineer to build and lead a platform engineering function, focusing on cloud rearchitecture, SRE practices, and developing an internal developer platform. This role requires a high level of ownership and collaboration with engineering teams to enhance infrastructure and operational efficiency.

Responsibilities

• Migrate all existing AWS and Azure infrastructure to OpenTofu/Terraform and Ansible; establish module standards, remote state, and GitOps-based plan/apply pipelines — no unmanaged resources
• Audit the cloud estate against the AWS and Azure Well-Architected Frameworks; produce a remediation backlog and drive it to completion across networking, IAM, landing zones, account structure, and cost governance
• Implement policy-as-code (OPA/Conftest, AWS SCPs, Azure Policy) to enforce security, tagging, and compliance guardrails at the platform layer — governance embedded, not bolted on
• Build and maintain reusable Terraform modules for compute (EKS, AKS, EC2), networking, storage, databases, and identity as shared building blocks for all engineering teams
• Define FinOps standards: tagging taxonomy, cost allocation dashboards, rightsizing recommendations, and reserved capacity planning across both clouds
• Design and implement the full observability stack: metrics (Prometheus/Datadog), logs (Loki/OpenSearch), traces (Tempo/Datadog APM), and dashboards (Grafana) — instrumented end-to-end via OpenTelemetry
• Define SLIs and SLOs for all platform shared services and critical applications; build error budget dashboards and burn-rate alerting — alert on symptoms, not raw metrics
• Establish the SRE practice from scratch: incident runbooks, post-incident review templates, and at least one chaos engineering exercise (AWS FIS or equivalent)
• Partner with engineering teams to instrument their services, define meaningful alerts, and build operational dashboards — reliability is a shared responsibility, not a platform team tax
• Build capacity planning models for compute and storage so engineering leadership can make data-driven scaling decisions
• Deploy and operate a developer portal (Backstage, GitHub or equivalent) as the single front door: service catalog, scaffolding templates, runbooks, API docs, and on-call ownership all in one place
• Build and maintain golden paths for the highest-frequency developer workflows: new service creation, Kubernetes deployment, database provisioning, secrets management, and CI/CD pipeline setup - opinionated defaults with escape hatches for legitimate edge cases
• Own the CI/CD platform layer: standardized pipeline templates (GitHub Actions, GitLab CI), reusable workflow libraries, container image build and scan pipelines, and environment promotion workflows with security scanning (SAST, Snyk) built in by default
• Own Kubernetes platform operations: EKS and/or AKS cluster lifecycle, Helm chart standards, admission controllers, RBAC, network policies, and service mesh (Istio or Linkerd)
• Build the self-service provisioning layer — Backstage scaffolder actions and Terraform automation so developers can provision approved resources without raising a ticket
• Measure adoption and run regular feedback sessions with engineering teams; iterate on golden paths based on real friction, not assumptions
• Partner with peer managers and teams to plan and support migration of existing workloads onto the platform; provide hands-on migration support, not just documentation
• Embed security by default across all platform work: IaC scanning (Checkov, tfsec), secrets management (Vault, AWS Secrets Manager, Azure Key Vault), RBAC, and container image hardening
• Write clear technical documentation, architecture decision records (ADRs), and runbooks; raise the documentation bar for the whole team
• Mentor and support more junior platform engineers; contribute to architecture reviews and build-vs-buy decisions alongside the Platform Engineering Manager

Skills

• 5+ years in platform, infrastructure, or DevOps engineering with direct production ownership on AWS and/or Azure
• IaC: Deep OpenTofu/Terraform proficiency: module authoring, state management, workspace strategy, remote backends, and CI/CD integration; Terramate a plus
• Kubernetes: Strong Kubernetes operations: EKS and/or AKS cluster lifecycle, Helm, admission controllers, RBAC, network policies, and autoscaling
• Observability & SRE: Hands-on observability experience with two or more of: Prometheus, Grafana, Loki, Tempo, Datadog, or OpenTelemetry — including SLI/SLO definition and alert engineering
• CI/CD: CI/CD platform experience: GitHub Actions pipeline authoring, reusable workflow design, and container build/scan pipeline ownership
• GitOps: GitOps: ArgoCD or Flux for Kubernetes continuous delivery; progressive delivery patterns (canary, blue-green) a strong plus
• IDP: IDP experience: Backstage or equivalent developer portal, GitHub, scaffolding templates, service catalog design, or self-service provisioning tooling
• Security: Security-first mindset: policy-as-code, IaC scanning, secrets management, container hardening, and shift-left security practices
• Strong communication and documentation skills; comfortable presenting architecture decisions to engineering peers and leadership
• SRE background: chaos engineering (AWS FIS, Chaos Monkey), error budget management, incident command, and capacity planning
• Service mesh depth: Istio or Linkerd — mTLS, traffic management, and observability integration
• FinOps tooling (Kubecost, CloudHealth) and reserved capacity planning experience
• Familiarity with AI/ML infrastructure basics: LLM API integration or model serving, as the platform will need to support these workloads
• Certifications: AWS Solutions Architect Associate/Professional, CKA/CKAD, Azure Administrator/Solutions Architect, HashiCorp Terraform Associate
• Python or Go for platform tooling and CLI development

Benefits

• Health, dental, and vision insurance
• A 401(k) plan with company match
• Flexible Work Environment Whether remote, hybrid, or in-office, we support work arrangements that promote productivity and balance
• Inclusive & Collaborative Culture We foster a workplace where diverse perspectives are valued, teamwork is encouraged, and everyone has a voice
