Fullstack Developer (React & TypeScript)

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. Working at Wolt isn't always easy, but it's definitely exciting. We're now looking for a FullStack Engineer with a Frontend focus to help design and build the internal products that enable observability across both Wolt and DoorDash. These tools are used daily by hundreds of engineers to operate services at massive scale—supporting workflows like debugging, incident response, performance monitoring, and system health insights.
As our observability platform continues to evolve, we're investing in purpose-built frontend experiences that meet the scale and complexity of modern telemetry. You'll play a central role in delivering fast, intuitive, and reliable interfaces that transform raw data into meaningful insight across logs, metrics, and traces.
You'll collaborate closely with backend engineers, infrastructure teams, and design system experts to build experiences that fit naturally into engineering workflows. It's a unique opportunity where frontend expertise, UX thinking, developer empathy, and a product mindset come together to drive platform impact at scale.
Design and implement fast, data-rich user interfaces that streamline how engineers explore signals, triage issues, and understand system behavior.
Develop frontend workflows that make complex telemetry data accessible and actionable—enabling better insight, faster debugging, and confident decision-making.
Build reusable components and UI patterns in collaboration with internal design systems and platform UX teams.
Work closely with backend engineers building telemetry pipelines, unified query layers, and distributed storage backends.
Proactively identify UX gaps, propose improvements, and experiment with new technologies or techniques to improve the developer experience.
Strong experience building modern frontend applications using React , TypeScript , and web-based visualization tools.
Familiarity with releasing and maintaining frontend applications in production, including CI/CD pipelines , automated testing, and performance monitoring.
Basic UX sensibility—able to design intuitive interactions in complex technical domains, even if you're not a designer by trade.
Contributions to open-source projects in the observability frontend space—e.g., Familiarity with observability standards like OpenTelemetry , especially in the context of frontend tooling or developer-facing workflows.
Experience with Slack-based developer tooling , triage dashboards, or real-time alerting UX.
Tackle high-scale, high-impact frontend challenges where usability, performance, and system understanding converge.
Influence the direction of frontend observability tooling—and have the opportunity to contribute to open-source projects and engage with the broader engineering community through talks, blog posts, or conference participation.
Enjoy a remote-friendly work environment, flexible culture, and strong peer support in a high-trust engineering team.
