At Wolt, we believe exceptional customer service is more than just a feature - it's a fundamental part of who we are . That's why we've built our own internal support tooling from the ground up, tailored to help our customer, courier, and merchant support teams shine in every interaction.
As we grow across 30+ countries, supporting millions of users and partners, our internal tools need to scale too. That's where the Support Comms team comes in, enabling support associates across Wolt operations to use our in-house communication platforms for both email and chat. Today, these platforms already handle millions of conversations every month - and we're building them to scale more than 10x to meet the needs of our fast-growing global community.
We're now looking for a Senior Backend Engineer (Node.js) to join our team in creating scalable, low-latency systems that help our 25M+ users and 300K+ partners get the support they need - quickly, reliably, and with a human touch.
This role can be based in one of our tech hubs in Helsinki or Stockholm.
What you'll do:
Build and maintain high-throughput backend services using Node.js.
Collaborate with product managers, designers, and frontend developers to ship features that support internal support agents across the globe.
Design systems that are scalable, resilient, and easy to maintain.
Lead and contribute to architectural discussions and technical decision-making.
Write well-tested code and help the team maintain high code quality standards.
Take ownership of services end-to-end - from design and implementation to monitoring and ongoing improvements.
Our humble expectations:
7+ years of production experience in Node.js, with the ability to mentor others in best practices.
Strong experience with SQL and NoSQL databases - especially Cassandra.
Experience designing and operating low-latency, high-throughput distributed systems is a big plus.
Product-oriented mindset - we value engineers who think beyond the ticket and understand the "why" behind the work.
Experience in leading projects or making key technical decisions is expected at this level.
Proven experience owning projects or components and driving them to completion.
Clear communicator with a collaborative spirit - we move fast, but we do it together.
Nice to have:
Background in Node.js or other backend languages.
Familiarity with cloud infrastructure (AWS, GCP) and event-driven architectures.
Previous on-call experience, with a pragmatic approach to reliability and incident management. We support healthy, balanced on-call practices and make sure responsibility is shared fairly.
Next steps:
We review applications on a rolling basis and encourage you to apply as soon as you feel excited about this opportunity. If you need any adjustments in our hiring process (for example, related to accessibility, caregiving, or personal circumstances), let us know - we'll be happy to support.
