We specialize in building partnerships between top brands and reputable publishers to drive revenue and business growth.

A Quick Peek at Affiliate Marketing Think back to your last online purchase. Did an influencer tip you off about a great product and offer a discount Or perhaps you relied on a trusted review site to make your decision Whatever path you took affiliate publishers likely played a role by influencing informing or helping you find the best deal. CJ connects brands with these publishers creating valuable resources for shoppers like you.
Overview
This is a hybrid role requiring 3 days a week
You must be work authorized in the United States without the need for employer sponsorship.
Must have Ad Tech / MarTech industry experience specifically in e-commerce travel and finance.
As a Senior Software Engineer on the Engineering Experience (EngExp) platform team you help run and evolve the platform that powers CJs production systems across multiple AWS regions. Platform here is broad - it is the Kubernetes clusters but also the observability stack every squad depends on the CI/CD and artifact infrastructure their builds run through the AWS networking that connects them the secrets and access systems that gate them and the cost visibility that keeps them accountable. EngExp owns all of it and this role touches most of it. This is not just an infrastructure role - your value is in engineering judgment. You are a leader on the team: you own the reliability and operability of the platform act as a critical reviewer of systems and changes set standards and mentor other engineers. We especially want someone with real depth in the systems below - we have made platform decisions we later had to reverse because the team lacked deep expertise in a component we owned and that depth is exactly what this role brings.
Responsibilities
The Systems You Work On:
Youll own their reliability be the critical reviewer of changes to them and raise the teams depth in them:
Observability & monitoring Prometheus Alertmanager Grafana and OpenTelemetry across every production region. This is not dashboard-building: you own cardinality budgets and recording-rule design keep a production Prometheus healthy as it outgrows a single shard (federation / sharding / long-term store strategy) and own Alertmanager HA and the blast radius of alert-routing config. Deep Prometheus and Alertmanager expertise is a core requirement.
Kubernetes & cloud infrastructure multi-region EKS clusters: upgrades node group and Karpenter management controller lifecycle and add-on / configuration management. Identify failure modes before they happen (subnet IP exhaustion API server latency ArgoCD reconciliation lag Prometheus cardinality Karpenter consolidation disruption).
AWS networking VPC design subnet allocation and CIDR management VPC peering Transit Gateway security groups Route53 and NAT gateway topology across multiple accounts and regions plus 24/7 networking alarms for all prod networking between clusters and squad resources.
CI/CD & artifact management GitLab administration (runner fleet AMI updates cache access - not just pipeline authoring) GitOps delivery through ArgoCD and the Nexus artifact repository including its storage lifecycle as it grows.
Access & identity Vault secrets management IAM roles and service accounts for apps in clusters cluster permission management for audit compliance and AI model access management (including cost alerts and reporting).
Cost observability OpenCost EBS orphan cleanup cost anomaly investigation and rightsizing attribution across teams so waste is attributable rather than shared overhead.
Internal tools & delivery the container image build pipeline and base image standards code audit tooling HedgeDoc and the UI CDN (S3 CloudFront) plus adopted applications with no other owner.
What Youll Do:
Own the reliability and operability of the systems above - focused on what is happening and why
Manage infrastructure-as-code with Terraform across AWS accounts
Act as a high-quality reviewer of infrastructure changes - Terraform Kubernetes configs CI/CD pipelines observability config - catching subtle issues and long-term risks before they ship
Turn recurring requests (ingress DNS service accounts) into self-service workflows that are hard to misuse
Drive resolution of platform incidents with a focus on learning and lasting system improvement
Evaluate new patterns (Gateway API / Kgateway claim-based self-service) on tradeoffs not hype
Mentor less-senior engineers and raise the teams depth in the components we own
Kubernetes controllers/operators (reconciliation patterns restart safety) - Go experience is a plus not required
Engineering Practices We Employ:
Agile software development
Infrastructure as Code (IaC)
Pair programming
Test-Driven Development (TDD)
Continuous Delivery
Qualifications
What We Look For:
6 years of experience in software and/or infrastructure engineering
Bachelors degree or equivalent experience
Deep hands-on production experience operating Kubernetes and AWS at scale across multiple accounts and regions
Real operational depth in at least one system we own beyond the cluster - most importantly the observability stack (Prometheus/Alertmanager at scale) but AWS networking Vault or artifact/CI infrastructure also count. We are filtering for people who have run these systems not just used them.
A track record as a critical reviewer - spotting subtle infrastructure issues and long-term risks before they ship
Experience leading technical work and mentoring engineers; can manage clarify and plan around uncertainty
Effective communication and the ability to influence design in a product-focused way
Nice to Have:
Prometheus long-term storage / sharding (Thanos Cortex Mimir or equivalent) run in production
Experience owning a container image / base image pipeline
Policy-as-code (Kyverno / OPA) and admission webhook design
Building claim-based self-service platform capabilities

This is a hybrid role requiring 3 days a week in office.
