Senior Staff Engineer, Fintech

About Wolt
At Wolt, we create technology that brings joy, simplicity and earnings to the neighborhoods of the world. In 2014 we started with delivery of restaurant food. Now we're building the delivery of (almost) everything and you'll find us in over 500 cities in 30 countries around the world. In 2022 we joined forces with DoorDash and together we keep on dreaming big and expanding across the globe.

Working at Wolt isn't always easy, but it's definitely exciting. Here you'll learn more, build more, and ship more than in most other companies. You'll be challenged a lot, but also have a lot of fun on the way. So, if you're a self-starter with drive and entrepreneurial spirit, this could be the ride of your life.

Wolt is looking for a Senior Staff Engineer to join our Fintech group and help shape the future of our Fintech products and platforms. This is a high-impact role that goes beyond a single project: you'll provide clarity, alignment, and technical leadership across multiple initiatives, ensuring our financial and compliance platforms scale reliably as Wolt continues to expand globally offering a broader set of financial products to Wolt customers and partners.

This position will involve close collaboration with senior engineering and product leaders, compliance specialists, and business stakeholders. The role is about connecting the dots across teams and organisations, guiding technical direction, and making sure decisions and platforms remain consistent as we grow.

While the primary focus will be on Fintech/Payments, the impact will extend across the company, influencing the Merchant, Courier, and Consumer domains, as well as compliance and accounting platforms.

For this role, you can be based in our tech hub cities (Helsinki, Berlin, Stockholm, Tallinn) or work remotely anywhere in Finland, Germany, Sweden, or Estonia - with occasional travel to connect with colleagues.

What you'll be doing

• Drive the technical vision and architecture for Wolt's global Fintech platforms, ensuring they are scalable, reliable, and compliant.
• Provide technical leadership across multiple teams and projects, bringing architectural consistency to complex, large-scale platforms.
• Partner with engineering and product leaders, as well as non-technical stakeholders, to align priorities and manage trade-offs.
• Contribute to end-user-facing financial and compliance platforms, ensuring consistency, accuracy, and robustness at scale.
• Lead large cross-team projects, guiding them from concept to rollout across multiple countries and time zones.
• Promote best engineering practices, mentor engineers across teams, and set the long-term technical direction.
• Act as a bridge between technical and non-technical colleagues, ensuring clarity and alignment across functions.
• Contribute to the technical roadmaps of Fintech platforms and products by facilitating and aligning with other senior engineers.

Our humble expectations

We're looking for someone with a mix of deep technical expertise, system-level thinking, and excellent communication skills.

Technical Expertise

• Proven track record designing and scaling large distributed systems.
• Experience delivering production-grade systems with compliance or financial requirements (fintech background is a plus but not a must-have).
• Ability to adapt quickly to new technologies and languages; while many of our services are written in Kotlin and Go, we are looking for a language-agnostic. (Prior experience in Go is a big plus).
• Ability to dive in quickly into new domains and projects.
• Strong understanding of system architecture, scalability, and reliability.
• Familiarity with modern cloud-native tools and data systems (e.g., Kubernetes, Kafka,, MongoDB).

Communication & Influence

• Strong communicator with the ability to influence, align, and build consensus across diverse teams and stakeholders.
• Comfortable working in a global environment across multiple time zones
• Skilled at translating complex technical decisions into clear direction for technical and non-technical audiences.

What we offer

At Wolt, this role provides a rare opportunity to make a wide-reaching impact on systems that are critical to our global business. As a Senior Staff Engineer, you will help build financial and compliance platforms that support millions of merchants, couriers, and consumers across continents. The scope of work spans global initiatives with colleagues across continents, and involves solving technical and organizational challenges at the intersection of large-scale distributed systems and Fintech.

Alongside the technical challenge, this role offers the chance to work closely with talented engineers and leaders, shaping Wolt's engineering culture while also mentoring and influencing others.
