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.

At Omnisend, we're entering a new phase embedding AI deeply into our product to help thousands of ecommerce businesses grow smarter and faster. This is your chance to be part of that transformation and work on solutions that have real, measurable impact on our customers.

We're building a new generation of AI powered capabilities, including a recommendation engine that helps customers make better decisions and drive more revenue, as well as an insights engine that analyzes millions of data points and delivers meaningful, near real-time intelligence. These are not experimental side projects; they are becoming a core part of how our product works and how our customers succeed.

Our approach is pragmatic and future focused. We are LLM agnostic by design, actively working with tools like OpenAI, Gemini, and Claude, while staying open to new models as the ecosystem evolves. This allows us to choose the best tool for each problem and continuously push the boundaries of what we can build.

What truly defines our team is how we work. We move fast from idea to production, constantly experimenting, iterating, and shipping improvements without unnecessary bureaucracy. AI is not treated as an add-on feature, but as a fundamental part of the product experience we are shaping.

As a Senior Software Engineer you'll be joining the Strategist Team that is actively defining what AI-powered marketing looks like in practice turning complex data into clear, actionable insights and delivering real value to customers every day.

What you’ll do @ Omnisend:

Play a key role in the Strategist team, influencing product development decisions.
Build a product that helps customers make smarter decisions through data-driven recommendations and insights.
Use your technical expertise to solve complex problems.
Leverage AI to streamline your daily operations and build AI solutions that drive real value for our customers.

We expect that you’ll bring:

Ability to make pragmatic decisions focused on delivering value rather than over engineering ideal solutions.
Customer and outcome oriented mindset, with the ability to translate complex data into impactful product capabilities.
Strong proficiency in Golang, or solid experience in another backend language (e.g., Python or Node.js) with a willingness to adopt Golang as a primary language.
Experience building backend services and APIs, capable of handling data intensive and high throughput workloads.
Practical experience working with machine learning systems and AI driven products, including LLM based solutions.
Experience integrating and working with multiple LLM providers (e.g., OpenAI, Gemini, Claude) or similar AI platforms.
Strong understanding of data processing and analytics, with hands-on experience in SQL and BigQuery (or similar data warehouses).
Experience designing and working with distributed systems, event driven architectures, and real-time data pipelines.
Familiarity with microservices architecture and best practices in system design.
Experience with cloud platforms (GCP preferred) and modern software development workflows, including CI/CD pipelines.
Experience building AI driven, data intensive, or customer facing products is a strong advantage.

How we work and what we value:

Company-wide OKR.
Empowered product teams that solve customer and business problems.
Objective-based planning and experimentation-driven delivery.
Product-led growth.
We look at product metrics daily, we speak to our customers and do it often.
Outcomes and bringing value to our customers over outputs and feature factories.
Ship to learn. Experimentation to validate hypotheses and assumptions.
Truly embracing data-driven decisions.

What we offer in return:

Gross salary starting point from 7800 EUR/month based on experience.
An unlimited learning budget for self-improvement complying with the best interest of Omnisend.
Working methods and best practices inspired by the best tech companies in Silicon Valley.
Senior colleagues (over 70%) enable us to have a high-performing, productive environment where your growth will accelerate.
Flexible working hours and remote work possibilities.
Private health insurance.
Unlimited access to psychotherapy.
Workstation budget.
Personalised work anniversary gifts (house cleaning, spa treatments, international flights etc.).
Attractive company-led yearly workation abroad and team-led team-building events.
