About the Role

Help keep a multi-service Ads platform healthy, scalable, and high-performing across AWS and GCP.

You’ll act as the senior engineer on the front lines of production reliability, incident response, and platform stability — with the opportunity to expand into deeper platform ownership, infrastructure design, and operational excellence.

This role requires strong hands-on debugging skills, cloud infrastructure knowledge, and the ability to confidently own production incidents in a US (PST) timezone environment.

What You’ll Do (Core Responsibilities)

• Triage and resolve production issues across the full stack (Next.js frontend, Node.js/NestJS backend, PostgreSQL, networking).

• Debug end-to-end systems using logs, traces, and metrics.

• Partner with product and engineering teams to identify root causes and prevent regressions.

• Improve observability (dashboards, alerts, tracing) and incident response processes.

• Create and maintain clear runbooks and operational documentation.

• Ensure platform reliability, availability, and performance across environments.

• Own production incidents during PST overlap hours.

Growth Areas / Expansion Opportunities

We’re looking for someone who can contribute immediately and grow into deeper platform responsibilities:

• Kubernetes & Argo CD: deployments, rollbacks, scaling, ingress/networking, secrets, config management.

• CI/CD & Infrastructure as Code: collaborate on pipelines and infrastructure using Terraform (AWS provisioned via Jenkins).

• Data operations fundamentals: support database jobs, backups, migrations, and performance troubleshooting.

• Platform automation and reliability improvements.

Requirements

• 7+ years of experience in Software Development, Application Support, SRE, DevOps, or Platform Engineering roles within microservices environments.

• Strong debugging skills across modern web applications and APIs (Node.js/NestJS, Next.js).

• Practical cloud knowledge (IAM, networking, containers, compute, storage).

• Experience with observability tools (logs, metrics, traces) and incident management.

• Experience supporting production systems at scale.

• Clear and calm communication under pressure.

• Comfortable working with and overlapping US (PST) timezone until 2:00 AM CET.

Nice to Have

• AWS (EKS/ECR, S3, CloudWatch) and/or GCP (GKE, GCS, Pub/Sub).GitOps workflows, blue/green or canary deployments, feature flags.

• Kafka/Redpanda experience.

• Security scanning, secrets management, policy-as-code.

• Experience in high-traffic Ads or real-time platforms.
