Email Deliverability Engineer

Salesforge builds cold email infrastructure: Salesforge, Mailforge, Infraforge, Primeforge and Warmforge. We're hiring an Email Deliverability Engineer to own deliverability across the whole product suite.

What you'll do

• Own all deliverability topics end to end: inbox placement, sender reputation, bounces, blocks and spam folder issues
• Manage our sending IPs: pools, warmup, rotation, reputation monitoring and blocklist remediation
• Run and tune our mail server stack (Postfix, Exim, Dovecot) on Linux
• Investigate client accounts with deliverability problems, find root causes and drive fixes with the customer and our support team
• Configure and audit email authentication: SPF, DKIM, DMARC, rDNS, MX
• Monitor mailbox provider signals (Google Postmaster Tools, Microsoft SNDS, feedback loops) and react before issues reach customers
• Work with backend engineers on tooling, alerting and automation for deliverability

What we're looking for

• 2+ years hands-on with email infrastructure or deliverability
• Strong Dovecot experience (must have), plus Postfix and/or Exim
• Deep understanding of SMTP, DNS and email authentication
• Comfortable on Linux servers: reading mail logs, debugging delivery, scripting
• Experience with IP warmup, blocklist delisting and reputation management
• Investigative mindset: you enjoy digging through logs and headers to find why mail isn't landing

Nice to have

• Background at an ESP or cold email / sales engagement platform
• Experience with PowerMTA, KumoMTA or similar MTAs
• Python, Go or Bash for automation

Why join

• Fully remote, with at least 4 hours overlap with GMT+3
• Own a business-critical area across five products
• Small, fast team working directly with the CTO
