About the role

Key responsibilities & impact

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

What you’ll need

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

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
