Are you passionate about building next-generation products with LLMs and generative AI? Do you want to work on technology that’s transforming how brands connect with people? Join the Conversational Ads team as a Senior Fullstack Engineer

Our mission is to build the leading AI-first platform for full-funnel conversational commerce in messaging channels, combining performance marketing with deep audience insights. This means creating features that help marketers easily craft, adapt, and optimize high-performing ads and enabling more meaningful, creative, and effective conversations between brands and their audiences.
We are technology agnostic and always strive to choose the best tools for the job. On the backend, our favoured stack is Node.js in combination with TypeScript usually coupled with PostgreSQL and RabbitMQ. On the front-end side of things, React with TypeScript is the flavour du jour.

Here’s what our people say about the team:

“I mostly enjoy how driven, passionate, and committed our team is to creating great products and staying close to our customers - and the autonomy we have to do so.”

“For me, it feels like we work with a start-up spirit: we love building cool things, aren’t afraid to break things to discover something even better, are willing to admit our mistakes, and are quick to iterate, fix issues, and make our customers happy.”

“I personally love the collaborative environment, where developers speak up when something doesn’t seem right instead of just blindly implementing it. In some companies, the process is very waterfall-like, with development as the final step and no input beforehand - here, it’s different.”

As a Senior Fullstack Engineer you will:
  • Have end-to-end ownership on expanding Conversational Ads experience for advertisers
  • Be involved in an innovative project that is central to Smartly’s growth
  • Design and build data-intensive microservices systems
  • Work on integration with Meta advertising API and services from multiple Smartly teams
  • Build internal tooling and abstractions to enable scalable, safe, and efficient use of GenAI technologies.
  • Collaborate with product managers, designers, engineers, and advertisers to understand campaign objectives, target audience demographics, and messaging requirements.
  • Apply and enhance your soft skills through working closely with your colleagues and our customers. Doing knowledge shares, running productive meetings, and pair programming/debugging are just some ways we grow.
  • Be part of an international, dynamic team with people who don’t take themselves too seriously and love to help each other. 
What we are looking for:
  • Experience in backend development using modern technologies. We use mostly NodeJS and Typescript, but we are open to hear more about technologies used by you
  • Contribute into UI development (React, Typescript) to ensure best user experience for our biggest customers and partners
  • Experience in building robust, complex and distributed web applications
  • Comfortable collaborating cross-functionally and translating ambiguous problems into scoped, testable engineering initiatives.
  • Motivation for solving customers problems and delivering value to customers at a fast pace
  • Ability and willingness to work in a hybrid capacity from our Helsinki office 3 days a week.
What We Offer You:
  • Inclusive Culture: Join a diverse team of over 750 Smartlies from 60+ nationalities across 24 locations in 13 countries. We foster a culture built on trust and open feedback.
  • Global Impact: Work on solutions that directly influence advertisers worldwide and drive business growth.
  • Wellbeing & Work-Life Balance: Benefit from comprehensive healthcare, mental health services, paid holidays, and family leave.
  • Total Rewards: Enjoy equity options, performance-based rewards, competitive compensation, and career development opportunities.
  • Hybrid Workplace: Flexibility to work in a hybrid model, with the option to work abroad for up to 30 days per year.

At Smartly, we are committed to creating an environment where growth-minded individuals can thrive. Explore more in our Culture Handbook!

What you need to know about the Belfast Tech Scene

If asked to name the birthplace of the RMS Titanic, you might not say Belfast. Similarly, if asked to name Europe's leading destination for foreign direct investment in new software development, Belfast might not come to mind. Yet, both are true. The city has emerged as a tech powerhouse, recently ranked among the best in the U.K. for tech careers — especially for software developers. It also leads the U.K. with the highest percentage of software development jobs advertised.
