Senior Software Engineer, Fullstack - (Global Search, Consumer Discovery)

As the world’s pioneering local delivery platform, our mission is to deliver an amazing experience, fast, easy, and to your door. We operate in around 65 countries worldwide powered by tech, designed by people. As one of Europe’s largest tech platforms, headquartered in Berlin, Germany. Delivery Hero has been listed on the Frankfurt Stock Exchange since 2017 and is part of the MDAX stock market index. We enable creative minds to deliver solutions that create impact within our ecosystem. We move fast, take action and adapt. No matter where you're from or what you believe in, we build, we deliver, we lead. We are Delivery Hero.

We are on the lookout for a Senior Fullstack Software Engineer to join our Search squad and help shape the next generation of how millions of customers find food. In this role, you will move beyond basic feature implementation to own the conversational search experience end-to-end—from the React web app that users interact with, to the Go backend service driving it. If you love building product surfaces that iterate fast on real user signals and care as much about the client as the server, you will thrive here.

At Delivery Hero, you’ll shape the global consumer experience for millions of users. Your work will have a direct impact on how we attract and retain customers, creating data-driven, personalized interactions that keep them coming back. As part of our Consumer Team, you’ll enhance customer satisfaction and drive global growth and profitability through innovative projects.

Your Mission

As a technical leader within Global Discovery, you will drive architectural decisions, own multiple high-impact features and act as a mentor to elevate engineering excellence across the squad.

• Conversational UX Innovation: Design, build, and own the conversational search web app—including the chat interface, query refinement chips, natural language nudges, and result rendering—delivered seamlessly inside our consumer mobile apps.
• High-Performance Backend Operations: Build and operate the backend service powering the experience, managing per-conversation state, upstream search engine integration, and streaming responses to the client.
• API Contract Stewardship: Define and maintain the API contract between the web client and the backend service, optimizing streaming protocols, interaction event schemas, and session state.
• Surface Instrumentation & Quality: Instrument the client surface to capture interaction events, refinement choices, and search outcomes, feeding live data into continuous evaluation and rapid iteration cycles.
• Cross-Functional Collaboration: Partner closely with mobile platform teams on webview integration edge cases and collaborate with Product to shape the conversational UX based directly on user signals.
• Architectural Thinking & Mentoring: Contribute to critical choices on where logic lives (client vs. server), advocate for the right trade-offs, and coach team members on engineering best practices and strategic AI usage.

Agentic Engineering & Coding Velocity

• Fluent Agentic Tooling: You are highly fluent in using agentic AI tools and autonomous development workflows (e.g., Cursor, Copilot, or equivalent AI-assisted platforms) to accelerate engineering execution, automate repetitive tasks, and optimize software delivery without compromising on code craft.
• Workflow Automation Mindset: A proactive drive to automate aspects of the software development lifecycle (SDLC) to help the team move at a rapid, high-impact pace.

Frontend Excellence & Component Craft

• TypeScript & React Mastery: Strong command of TypeScript and React, with deep comfort handling typed component trees, state management (we use MobX), and CSS-in-JS. You think carefully about component API design, accessibility, and testability.
• Modern Web Architecture: Familiarity with micro-frontend architectures or module federation patterns.

Robust Backend & Streaming Systems

• Go Backend Confidence: Proven experience building and owning production-grade backend services in Go, specifically handling stateful APIs, streaming contracts, and gRPC integration with upstream services.
• Data & Search Infrastructure (Nice to have): Familiarity with search/recommendation systems, event streaming, and near-real-time data pipelines.

End-to-End Ownership & Product Instinct

• Fullstack Delivery: A track record of shipping client-facing surfaces or SDKs from design to production, taking absolute accountability for both sides of the stack.
• Product-Driven Execution: Strong product instinct; you shape interaction patterns based on user signals rather than waiting for a rigid specification, moving fast to validate core assumptions.

Strategic Leverage & Collaboration

• Strategic AI Leverage: Ability to utilize AI-assisted development tools strategically, knowing exactly when AI accelerates velocity versus when deep, hands-on critical thinking is required.
• Mobile Ecosystem Empathy (Nice to have): Experience with Swift or Kotlin, helping smooth over collaboration with mobile teams during webview integration.
• Clear Communication: Excellent written and verbal communication skills in English.

Ensuring you and all our Heroes are looked after, happy, and healthy is always on the menu. Because if you’re in good shape, then we’re in good shape.
