Job ID: 39378124

Budget: ₹500,000 – ₹1,000,000 INR

Location: Remote / India
Type: Full-time (Contract or Founding Team Role)
Experience: 5–10 years (DevOps + Backend)

About the Role:

We are building a global-grade Email Service Provider (ESP) platform — reliable, secure, and optimized for inbox deliverability — to compete with the likes of MXroute and Inframail.

We’re looking for a hands-on Lead Engineer / Technical Architect to design, build, and launch the complete infrastructure and customer-facing platform. You’ll work closely with the founder to own the technical roadmap, choose the right stack, and lead all core engineering efforts from Day 1.

Responsibilities:

Architect and deploy a scalable, secure email hosting infrastructure using Postfix, Dovecot, Rspamd, and Docker (Mailcow or custom)

Set up and maintain SMTP, IMAP, and webmail (Roundcube or SoGo)

Configure and automate DNS record handling (SPF, DKIM, DMARC, rDNS, MTA-STS, BIMI)

Integrate API-based provisioning, billing (Stripe/PayPal), and user management

Build and manage backend systems (Node.js/PHP) and user dashboard (React preferred)

Optimize for deliverability, email queue management, spam filtering, bounce handling

Implement monitoring, logging, and backup systems (Grafana, Netdata, Prometheus, UptimeRobot)

Collaborate with UI/UX, frontend, and DevOps partners/freelancers

Ensure compliance with email laws (CAN-SPAM, GDPR) and build for high uptime (99.9%+)

Required Skills & Experience:

Deep experience with email infrastructure: Postfix, Dovecot, DNS configs, TLS/SSL, spam filters (Rspamd, ClamAV)

Solid background in DevOps and Linux systems administration

Proficiency in backend development (Node.js or PHP preferred)

Experience working with Docker, Mailcow, or similar stacks

Familiarity with DNS APIs (Cloudflare preferred) and domain verification logic

Strong grasp of email deliverability practices and server hardening

Experience building secure, multi-tenant SaaS platforms

Knowledge of monitoring, logging, and incident response

Ideal Candidate:

Has built or contributed to email platforms, ESPs, or similar infrastructure-heavy products

Thrives in early-stage product development with minimal hand-holding

Comfortable making architectural decisions and owning full-stack technical delivery

Can grow into a CTO-level leadership role if the product succeeds

Nice-to-Have:

Experience with Mailcow, iRedMail, or Haraka

Prior work with SMTP relay APIs (Mailgun, Postmark, SES)

Understanding of email compliance, legal frameworks

Background in startup environments or bootstrapped SaaS
