They treat infrastructure as code, and prioritize reliability above all else, and seeking a Messaging Platform Engineer to architect the next generation of their critical messaging grid. You’ll move beyond managing servers to building the CI/CD pipelines, Observability stacks, and Event-Driven APIs that power the firm's global communication.\n\nThe Role\nThis is not a standard administration role; it is a Production Engineering position. You will own the reliability and architecture of a complex hybrid stack (Linux/Postfix + Microsoft Exchange). You will partner directly with software developers to decouple legacy monolithic systems and replace them with modern, API-first microservices.\n\nKey Responsibilities:\nEngineer high-availability, stateless Postfix clusters on Linux. Implement modern Infrastructure as Code (IaC) practices using Terraform or Ansible to manage configuration drift and deployment.\nMove beyond ‘up/down’ monitoring. Build sophisticated dashboards (Prometheus, Grafana, ELK) to visualize queue latency, delivery rates, and SMTP performance in real-time.\nLead the architectural shift from legacy EWS Polling to Event-Driven Graph API Webhooks. Architect the \"glue\" code in Python or Go that allows internal apps to send mail without touching the backend directly.\nProgrammatically manage Sender Reputation. Automate IP warming strategies and enforce DMARC/DKIM/SPF standards across thousands of domains to ensure 99.99% deliverability.\nManage the edge defense layer (Proofpoint/Mimecast) using policy-as-code where possible, focusing on threat detection and automated remediation pipelines.\n\nWho you are:\n7+ years of Engineering experience in high-volume messaging or complex infrastructure environments.\nDeep comfort with the Linux kernel, TCP stack tuning, and Postfix/MTA configuration management.\nProven experience writing production code (Python, Go, or advanced PowerShell Core) to wrap APIs and automate workflows. You don't just run scripts; you build tools.\nExperience managing infrastructure via Terraform, Ansible, or similar config management tools.\nYou understand SMTP, TLS, and DNS at the packet level and can debug complex handshake failures in a Wireshark trace.","company":"Elliot Partnership","rawCompany":"elliot partnership","city":"New York","state":"NY","isRemote":false,"isActive":false,"createdAt":"2026-06-26T03:30:58.964Z","occupations":[{"code":"15-1299.08","title":"Computer Systems Engineers/Architects","slug":"computer-systems-engineers-architects"},{"code":"15-1244.00","title":"Network and Computer Systems Administrators","slug":"network-and-computer-systems-administrators"},{"code":"15-1252.00","title":"Software Developers","slug":"software-developers"}],"industries":[{"code":"541512","title":"Computer Systems Design Services","slug":"computer-systems-design-services"},{"code":"513210","title":"Software Publishers","slug":"software-publishers"},{"code":"541511","title":"Custom Computer Programming Services","slug":"custom-computer-programming-services"}],"jobPosting":{"@context":"https://schema.org","@type":"JobPosting","title":"Messaging Platform Engineer (Linux & Postfix)","description":"Messaging Platform Engineer\nNew York, NY (Hybrid, 3 days in office)\nTop-tier compensation package\n\nJoin an elite technology group where systems engineering is a competitive advantage.
