Job Technologies
Your role in the team
- 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.
- 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.

Our expectations of you
Qualifications
- 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.
- 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.
- Modern Web Architecture: Familiarity with micro-frontend architectures or module federation patterns.
- Data & Search Infrastructure (Nice to have): Familiarity with search/recommendation systems, event streaming, and near-real-time data pipelines.
- 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 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.
- Clear Communication: Excellent written and verbal communication skills in English.
Experience
- 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.
- Mobile Ecosystem Empathy (Nice to have): Experience with Swift or Kotlin, helping smooth over collaboration with mobile teams during webview integration.
