Job Description

Working at Omnisend is... kind of boring.

Not the soul-crushing kind of boring — more like the “no drama, no chaos, just smart people doing great work” kind. The kind that lets you focus on what matters, without pointless meetings, micromanagement, or bureaucracy. We’re data-driven. We test, we iterate, we improve. Gut feelings don’t drive decisions — insights do. We trust each other. We’re transparent, give real feedback, and actually listen. No egos, no hand-holding — just a team of experienced professionals moving fast, adapting easily, and delivering impact. Omnisend is customer-funded and customer-driven. Our work is rooted in solving real problems that help ecommerce brands grow. No empty promises — we bring in results. And yes, we have fun. But the grown-up kind — workations, team gatherings, the occasional party. No forced fun, no awkward icebreakers. Just genuine moments with a team that actually enjoys working together.

The Message Delivery team is the backbone of Omnisend’s multichannel communication stack — ensuring that millions of marketing messages reliably reach inboxes, phones, and browsers every day.

We’re responsible for the reliable, fast, and compliant delivery of email, SMS, and push notifications. Our scope includes:

Managing message sending infrastructure;

Enabling message rendering and personalization across channels;

Powering message tracking, analytics, and logs for customers and support;

Collaborating with Product, Support, and Customer Success to deliver high-quality CX

We are looking for a Senior Full-stack Engineer with a preference for backend development. People that are proactive, product-minded and enthusiastic about crafting the impactful software product for our customers find a best fit at Omnisend.
