- Senior Messaging Infrastructure Engineer
- New York, NY (Hybrid, 3 days in office)
- Highly competitive compensation package
Join an elite technology and research group at the forefront of global finance, where world-class engineering and quantitative research converge. This firm treats infrastructure as code and systems engineering as a competitive advantage. We are seeking a highly skilled technical leader to take ownership of the firm's critical messaging ecosystem-a complex environment where reliability is paramount, and innovation is constant.
The Role
We are seeking a deeply experienced Senior Messaging Infrastructure Engineer to serve as the firm's Subject Matter Expert (SME) on all mail-related technologies. This is not a standard administration role; it is an engineering position that requires you to bridge the gap between legacy stability and modern agility. You will own the architecture of a hybrid messaging stack that spans both Windows and Linux environments, and you will partner directly with software developers to modernize how the firm consumes and processes communication-from API migrations to Generative AI prototyping.
Responsibilities
- Design, implement, and maintain a complex, high-availability messaging infrastructure involving Microsoft Exchange (On-Premises & Online) and Linux-based mail services (Postfix).
- Lead high-impact projects to modernize the messaging environment, specifically guiding the migration of applications from legacy EWS to Microsoft Graph API.
- Oversee the evolution of the desktop experience, managing the transition from COM-based integrations to modern Outlook JS add-ins and prototyping new AI-driven workflows.
- Act as the primary owner for mail security and hygiene, managing sophisticated anti-spam and threat protection gateways (Proofpoint) to protect the firm's proprietary data.
- Serve as a technical advisor to internal development teams, utilizing PowerShell or Python to build automation and troubleshoot complex mail routing logic.
What you'll bring:
- 7+ years of experience managing complex, enterprise-scale messaging capability.
- Demonstrable proficiency in managing both Microsoft Exchange (Hybrid/Online) and Linux-based mail systems (Postfix).
- Deep familiarity with mail-related APIs (EWS, Graph API, MAPI) and experience helping software engineers integrate with messaging platforms.
- Proven expertise in mail security protocols and gateways (specifically Proofpoint or similar enterprise-grade tools).
- A track record of troubleshooting advanced Outlook client-side issues and dissecting complex mail-flow problems in a high-pressure environment.
