We’re looking for a Senior Fullstack Engineer to join Smartly and help shape the future of our multi-channel advertising
platform.
You’ll be working on expanding Smartly into both new and existing advertising channels. Depending on the team,
this can mean greenfield development of new integrations or evolving and scaling established ones like Pinterest.
While we
can’t share all the details yet, this is a highly strategic area for the company with strong leadership visibility and direct
revenue impact. Whether you’re building something new or improving existing integrations, the work goes beyond incremental
changes. You’ll be building new capabilities, improving existing ones, and helping shape how different channels are integrated
into our platform at scale.
In this role, you’ll design systems that power automation for some of the world’s largest
advertisers. You’ll work closely with partners like Google, Reddit and Spotify, building deeply integrated solutions that enable
customers to launch, optimize, and iterate campaigns efficiently.
You’ll also have the opportunity to explore how AI and
automation shape the future of ad tech, and turn those ideas into production-grade systems.
This role is about ownership
and technical influence. You’ll contribute to architectural direction, make trade-offs that balance scalability and product needs,
and collaborate across teams to create a unified platform experience across channels.
We’re hiring for multiple positions
across a range of seniority levels, and we’ll align the role scope and level based on each candidate’s experience during the
hiring process.
Our tech stack
- Backend: Node.js, TypeScript
- Frontend: React,
TypeScript
- Infrastructure: PostgreSQL, RabbitMQ, Redis, Kubernetes
- Architecture: Distributed systems,
event-driven services, large-scale data processing
What you’ll do
- Own the design and implementation
of new platform integrations end-to-end
- Design and operate distributed, data-intensive systems and microservices at
scale
- Build automation systems that process large volumes of campaign and performance data
- Develop and evolve
client-facing APIs and backend services
- Drive architectural decisions and contribute to long-term technical
direction
- Work across teams to align on shared patterns and unify channel behavior within the platform
- Partner
closely with product and design to shape solutions, not just implement them
- Mentor other engineers and raise the bar for
engineering quality and practices
What we’re looking for
- Strong experience building and operating
production-grade systems with Node.js and TypeScript
- Solid frontend experience with React and modern web development
practices
- Experience designing distributed systems and working with asynchronous, event-driven architectures
- Proven ability to build scalable systems that handle high data volumes
- Ability to take ownership of complex problems
and drive them from concept to production
- Strong collaboration skills and experience working across teams and
disciplines
- Interest in mentoring and contributing to team-level engineering practices
- Ability and willingness
to work in a hybrid setup from our Helsinki office (3 days per week)
