Software Engineer - Infrastructure

Emergent Labs is a company focused on building autonomous coding agents for software development. The Software Engineer - Infrastructure will maintain platform stability, manage Kubernetes workloads, and enhance observability while collaborating with product and backend teams.

Responsibilities:

• Maintain stability of our platform consisting of distributed microservices closely interacting with Kubernetes and cloud providers (GCP, AWS)
• Manage Kubernetes workloads with ArgoCD (GitOps) — deploy, monitor, and troubleshoot application syncs, resource trees, and rollouts
• Debug and resolve complex Kubernetes issues across clusters
• Manage CDN and edge infrastructure (Cloudflare) for performance, caching, and traffic management
• Automate infrastructure lifecycle operations and workflows
• Own the observability stack: Grafana (dashboards, Loki logs, Prometheus metrics), New Relic (APM, golden metrics, transaction analysis)
• Enhance monitoring, alerting, and distributed tracing across services
• Participate in on-call rotation via PagerDuty, handle incident response, and perform root cause analysis
• Proactively identify reliability risks before they become incidents
• Support the platform that runs AI agent workloads — job scheduling, trajectory tracking, environment provisioning, deployments and cost attribution
• Develop Kubernetes controllers and operators to extend platform capabilities for agent orchestration
• Work closely with product and backend teams to ensure platform scalability and reliability
• Build internal tools, automate workflows, and integrate systems to improve team productivity
• Stay current with Kubernetes releases, CNCF ecosystem updates, and cloud-native best practices

Requirements:

• 4+ years of software/platform engineering experience with production systems
• Strong proficiency in Go or Python — you write production code in at least one daily
• Hands-on experience building and deploying services on Kubernetes — not just YAML, you've developed something that runs on K8s
• Experience with GitOps tooling (ArgoCD, Flux, or similar)
• Strong networking and DNS fundamentals — TCP/IP, HTTP, load balancing, DNS resolution, TLS, and debugging connectivity issues
• Solid Linux/OS fundamentals — process management, filesystem, memory, systemd, and comfortable debugging with tools like strace, tcpdump, and netstat
• Relational databases — experience with PostgreSQL, MySQL, or similar; indexing, query optimization, replication, and backup/restore procedures
• NoSQL databases — familiarity with MongoDB, DynamoDB, Redis, or similar for document/key-value workloads
• Caching — experience with Redis, Memcached, or similar for application and infrastructure-level caching
• Message queues & streaming — hands-on with Kafka, SQS, RabbitMQ, or similar for event-driven architectures
• Strong SQL skills for debugging and operational queries
• Comfortable with the CNCF ecosystem — Helm, Kustomize, cert-manager, Ingress controllers, CNI/CSI interfaces
• Hands-on with at least one observability stack (Grafana/Prometheus/Loki, New Relic, Datadog, or similar)
• Familiarity with GCP and/or AWS — managed Kubernetes (GKE/EKS), networking, IAM, storage, and cloud-native services (SES, SQS, S3, etc.)
• Experience with CDN/edge platforms (Cloudflare, CloudFront, or similar)
• Experience building Kubernetes Operators (kubebuilder, operator-sdk, or controller-runtime)
• Experience tuning Kubernetes core components (API server, kubelet, scheduler)
• Familiarity with AI/LLM infrastructure — token management, cost tracking, agent orchestration
• Experience with CI/CD pipelines (GitHub Actions, automated testing, deployment pipelines)
• Infrastructure as Code experience (Terraform, Pulumi, or similar)
• Previous work on large-scale distributed systems or platform-as-a-service
• Startup experience — you thrive in fast-paced, ambiguous environments
