Wolt is looking for a Senior Frontend Engineer to expand our Consumer Web Platform team. The team is part of the Consumer Product group and is responsible for enabling the delivery of the consumer web apps – most notably wolt.com – that millions of people in over 32 countries around the world see when ordering food and other products.

Our client platform teams share a clear mission:

“Enable delivery and ownership of Wolt-grade Consumer Client Applications through engineering excellence and domain expertise.”

What You’ll Be Doing

• Building the Foundation of our top-rated consumer-facing applications, ensuring high performance, security, and reliability at scale.
• Enabling Product Teams: You’ll provide a robust platform that makes it simple and fast for our feature teams to reach millions of users.
• Driving Technical Initiatives around architecture, developer experience, observability, performance, and more.
• Supporting Engineering Excellence: Champion best practices, improve developer workflows, and continually raise the bar for code quality.
• Long-Term Thinking: Balance short-term deliverables with long-term platform health to maintain a maintainable, extensible, and secure environment.

If you love collaborating with multiple engineering stakeholders, focusing on the long-term quality of the user experience, and making life easier for fellow engineers, this is the team for you!

📍This role can be based in one of our tech hubs in Helsinki or Stockholm. Read more about our hybrid setup here.

🤖 AI-First Engineering - What This Means Here

We're building teams at the forefront of agentic coding. This isn't about using Copilot to autocomplete boilerplate. We mean engineers who:

• Design workflows where AI agents handle entire task loops, from spec to PR.
• Think in terms of orchestration: what does a human review, what does the agent own?
• Build internal tooling and abstractions that make AI-assisted development faster and more reliable for the whole team.
• Stay curious and ahead of the curve - trying new models, agents, and tools as they emerge, and forming strong opinions about what's genuinely useful vs. hype.

If you find yourself naturally asking "can an agent do this?" before reaching for the keyboard, you'll fit right in.

Must haves

• Proven expertise in building consumer-facing frontend applications, using TypeScript and React.
• Prior experience on a platform/infrastructure engineering team - owning things like CI/CD, release pipelines, observability, performance, or developer experience for a shared codebase used by multiple feature teams (not solely feature/product team experience).
• Heavy, daily user of AI coding tools (e.g. Claude Code, Codex) - using agentic workflows for real feature/PR work, not just autocomplete.
• Able to lead and drive technical projects and improvements across an engineering organization.
• Excellent analytical and problem-solving skills.
• Ability to write efficient, maintainable, and scalable code.
• Strong communication skills with the ability to work effectively in a team environment.

Nice to haves

• Experience working in larger engineering organizations, with the scale, process, and cross-team coordination that comes with it.
• Strong knowledge of browser rendering behavior and optimization strategies.

Why Join Us?

• Impact: Build and shape the core web platform that supports millions of users worldwide.
• Collaboration: Work with talented engineers across Wolt to deliver real value to customers.
• Growth: Take on complex challenges and grow your skill set in a supportive, forward-thinking environment.
