Senior Site Reliability Engineer, SRE, Backend

Jobtailor; Berlin; Vor Ort; EUR 90.000 - 130.000; Vollzeit

Zusammenfassung

Jobtailor in Berlin seeks an experienced SRE/DevOps engineer to own AWS infrastructure end to end, implement CI/CD pipelines, and design resilient event-driven services. You will manage serverless and containerized workloads with Terraform modules and clear state management, while mentoring engineers on operational excellence.

The role emphasizes blameless incident response, postmortem improvements, GDPR/compliance awareness, and cost-optimized AWS spend without sacrificing reliability.

Qualifikationen

• 5+ years in SRE/DevOps, production ownership.
• Deep AWS experience across serverless and containers (Lambda, ECS Fargate).
• Strong Terraform skills with multi-environment state management.
• Hands-on experience with event-driven architecture (SQS, SNS, EventBridge).
• PostgreSQL: tuning, indexing, connections, zero-downtime migrations.
• Production observability with Datadog or equivalents.
• Backend coding in Python/Node.js/Go.
• On-call and incident postmortems experience.
• Security fundamentals: IAM, secrets, network isolation.
• Clear communicator able to explain tradeoffs without jargon.

Aufgaben

• Own AWS infrastructure end to end; design resilient services.
• Build and maintain CI/CD pipelines with safe rollout and rollback.
• Design event-driven services with retry and idempotency.
• Lead incident response and write postmortems that drive change.
• Harden security posture: IAM, secrets, network boundaries, GDPR compliance.
• Monitor and optimize AWS spend without sacrificing reliability.
• Contribute to backend development and data pipelines.
• Mentor engineers on operational excellence and architectural decisions.

Jobbeschreibung

• Own our AWS infrastructure end to end — Lambda, ECS Fargate, SQS, SNS, EventBridge, SES, Cognito, DynamoDB, RDS Postgres, and DMS
• Manage everything as code in Terraform, with well-designed modules, clean state management, and a solid review workflow
• Build and maintain CI/CD pipelines with safe rollout and rollback across web, mobile backends, and infrastructure
• Design our event-driven services for resilience: retries, dead-letter queues, idempotency, graceful degradation
• Own our Datadog and Sentry setup — define SLOs, build dashboards, and keep alerting actionable instead of noisy
• Lead incident response and run blameless postmortems that actually change how we build
• Harden our security posture: IAM, secrets management, network boundaries, Cognito auth flows, and vulnerability remediation
• Protect sensitive health data and support our GDPR and compliance requirements
• Monitor and optimize AWS spend without compromising reliability
• Contribute to backend development — APIs, event consumers, data pipelines, and Postgres and DynamoDB performance
• Participate in architectural discussions and mentor engineers on operational excellence

Requirements

• 5+ years in SRE, DevOps, platform, or backend engineering, with real production ownership
• Deep AWS experience across serverless and containers — Lambda, ECS Fargate, and debugging both under pressure
• Strong Terraform skills, including module design and managing state across multiple environments
• Hands-on experience with event-driven architecture (SQS, SNS, EventBridge) and a healthy respect for its failure modes
• Solid PostgreSQL: query tuning, indexing, connection management, and zero-downtime migrations
• Production experience with Datadog or a comparable observability platform (Grafana, New Relic, Honeycomb)
• Comfortable writing production backend code in [Python / Node.js / Go]
• Genuine on-call and incident response experience — you've led an incident and written the postmortem
• Strong security fundamentals: IAM, least privilege, secrets, network isolation, common web vulnerabilities
• Pragmatic about complexity — you reach for the simplest thing that meets the reliability bar
• Effective communicator who can explain a technical tradeoff without jargon

Core Competencies

Demonstrates extensive expertise in AWS infrastructure management, including serverless and containerized environments, while ensuring compliance with GDPR and security best practices. Proficient in Terraform for infrastructure as code, alongside strong backend development capabilities in Python, Node.js, or Go.
