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.

We move fast. We are flexible and adaptable to an ever-changing business environment to deliver value to our customers. Running lots of experiments and validations helps us to deliver what truly matters. Data-driven nature enables us to measure real impact and adjust. Customer feedback and daily contact create opportunities to solve problems our customers really need to be solved.

We are product engineers at heart. Cross-functional teams, led by engineering and product managers, and designers, deliver services capable of processing billions of records using event-based architecture in real time, sustaining millions of visits per day, and sending tens of billions of communications per year.
