About CJ Engineering

Are we a good match for you?

At CJ, we are passionate about software engineering. We build exciting software, with quality and maintainability in mind. We believe in common sense, simplicity, and efficiency. We practice critical thinking, challenge each other no matter the title, and believe in the wisdom of the team.

That makes us Engineers and not just developers. Here are some of the principles that set CJ engineers apart.

• Engineering autonomy: Here, business decisions are made by business people, and technical decisions are made by technical people.

• Full stack: Expect to be involved and to gain competence in every aspect of software engineering, from frontend, to database, to requirements analysis, to testing, to helping choose technologies.

• Clean, Maintainable code: Code is read more often than it is written, so we put in the effort to write it well in the first place.

• Pairing: The highest quality code is produced by close collaboration, so we pair by default.

• TDD: Quality is baked into our process through Test Driven Development

• Ownership: Engineers own the full lifecycle of what they build-from design and implementation to deployment, monitoring, production support, and on-call rotations. If we build it, we support it.

• Operational Excellence: We embrace Infrastructure as Code, CI/CD, automation, and observability to build reliable systems and deliver software safely, efficiently, and at scale.

• We believe in Agile values, and incremental development. We constantly experiment, retrospect, and adjust.

• We are committed to finding out how AI can amplify our productivity. We view AI as a force multiplier, not a replacement for good engineering.

If this sounds exciting, we want to hear from you!

As a Software Engineer 2 on the Engineering Experience (EngExp) platform team, you help run and improve the platform that powers CJ's 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, and the secrets and access systems that gate them. EngExp owns all of it. This is a hands-on, operationally-focused role: you'll take on well-scoped work across these systems, ship it end to end, and build real depth in them with senior engineers alongside you. We are looking for someone genuinely curious about how these systems work under the hood and eager to grow into owning them.

Responsibilities

The Systems You Work On:

EngExp owns the systems below. You'll contribute to operating them and build depth in them over time, starting with guidance from senior engineers:

• Observability & monitoring - Prometheus, Alertmanager, Grafana, and OpenTelemetry across production regions. You'll add and tune metrics, dashboards, and alert rules, and learn how Prometheus and Alertmanager actually behave at scale - cardinality, recording rules, and alert routing. This is real depth to grow into, not just dashboard-building.

• Kubernetes & cloud infrastructure - multi-region EKS clusters: routine maintenance, node group changes, controller upgrades, and add-on configuration, with senior engineers alongside.

• AWS networking - VPCs, subnets and CIDR management, security groups, and Route53. You'll help keep prod networking healthy and learn the multi-region topology.

• CI/CD & artifact management - GitLab CI/CD pipelines, GitOps delivery through ArgoCD, and the Nexus artifact repository.

• Access & identity - IAM roles and service accounts for apps in the clusters, Vault-managed secrets, and fulfilling access requests - then helping turn the repetitive ones into self-service.

• Cost observability - OpenCost and cleanup work (e.g. orphaned EBS volumes) so cost is attributable rather than shared overhead.

What You'll Do:

• Pick up well-scoped platform work across the systems above and ship it end to end

• Build and maintain GitLab CI/CD pipelines and GitOps delivery through ArgoCD

• Write and review infrastructure-as-code with Terraform for AWS resources

• Add and tune observability - Prometheus metrics, Grafana dashboards, Alertmanager rules

• Help fulfill and then automate recurring requests (ingress, DNS, service accounts, IAM roles)

• Help investigate platform incidents and document what you learn

• Learn to recognize common failure modes (IP exhaustion, resource limits, reconciliation lag) and escalate them early

Technologies We Use:

• Kubernetes / EKS (multi-cluster, multi-region), Karpenter, cert-manager, external-dns

• Prometheus, Alertmanager, Grafana, OpenTelemetry (and long-term storage / sharding for Prometheus)

• AWS networking (VPC, VPC peering, Transit Gateway, Route53, NAT Gateway, security groups, subnet/CIDR design across accounts and regions)

• Terraform, AWS (IAM, EKS, S3, EBS)

• ArgoCD, GitLab CI/CD, Nexus (artifact registry), Docker, container image build pipelines

• Vault, OpenCost

Qualifications

What We Look For:

• 1-2 years of experience in software or infrastructure engineering

• Bachelor's degree or equivalent experience

• Comfortable in the terminal and reading YAML, Terraform, or similar declarative config

• Some exposure to cloud (AWS or equivalent) and containers - production Kubernetes experience is a plus, not a requirement

• Genuine interest in operating real systems - especially observability - and growing deep in them

• Willing to learn how systems fail and to ask questions when something looks off

• Effective communication; enjoys pair programming and code review

Nice to Have:

• Hands-on exposure to Kubernetes, Terraform, or GitLab/GitHub CI/CD

• Any experience with Prometheus/Grafana or another metrics stack

• Scripting in Python, Bash, or Go

What Success Looks Like:

• You reliably deliver well-scoped platform work end to end with decreasing oversight

• You're building genuine depth in at least one system we own, not just familiarity with the tools

• Other engineers find the workflows you touch easier and more predictable to use
