Descrizione del lavoro

Tenarai - LATAM is building and operating an internal reliability platform that tracks, analyzes, and communicates operational risk across the org. You will design and run serverless Go services, manage infrastructure with CDK, and ensure robust observability, security, and AI agent integration.

The role requires hands-on AWS serverless experience, strong Go skills, and familiarity with incident workflows and ITSM tools. You will participate in on-call and contribute to internal tooling UI.

Competenze

• Hands-on AWS infrastructure experience, esp. Lambda and serverless architectures.
• Observability: metrics, logging, alerting, tracing, troubleshooting production issues.
• Strong Go development skills.
• AWS CDK (TypeScript) for provisioning/infrastructure management.
• REST API design, testing, CI/CD, and debugging distributed, event-driven systems.
• Nice to have React for internal tools UI.
• Python for agent services/scripting.
• Experience with ITSM or operational workflow tooling.
• Familiarity with Langfuse or MCP and LLM agents.
• Security and compliance work: runtime upgrades, vulnerability remediation, privacy scanning.

Mansioni

• Design, build and operate serverless backend services (Go) on AWS.
• Define and ship infrastructure as code with AWS CDK for multi-environment deployments.
• Build observability into everything: dashboards, alerts, logs, and tracing.
• Carry the alerts and on-call.
• Integrate with internal platforms and third-party systems with retries and safe rollbacks.
• Keep services secure and compliant: least-privilege IAM and data privacy requirements.
• Help expose services to AI agents and support tracing behind them.
• Contribute to the UI where needed.

About the role

We build and operate org's internal reliability platform: the services that track, assess andcommunicate operational events and risk across the company. Our work includes risk scoring,event workflows, Slack-based notifications, and AI-powered insights agents that give engineersroot-cause analysis and risk context. Our services are serverless and event-driven on AWS, andwe own them end to end, from design to on-call.

• Define and ship infrastructure as code with AWS CDK, including org CDK constructs andmulti-environment deployments.
• Build observability into everything: dashboards, alerts (Grafana-like tooling), logs (CloudWatch,Splunk) and tracing.
• You’ll also carry the alerts and on-call.
• Integrate with internal platforms and third-party systems, and keep state consistent acrossthem with retries, idempotency and safe rollbacks.
• Keep services secure and compliant: supported runtimes, least-privilege IAM, last-mileauthentication, and data classification and privacy requirements.
