This role <strong>focuses on building AI systems</strong> that can see and understand, going beyond text to tackle complex visual inputs — from everyday photos to noisy, low-resolution images captured in uncontrolled environments.</p><p>You’ll work at the<strong> intersection of computer vision and natural language processing</strong> to build <strong>multimodal AI pipelines</strong> that extract structured insights from unstructured, image-based content. Your work will ship, not sit in research notebooks.</p><p>We don’t just build models — <strong>we build autonomous, adaptive systems that orchestrate reasoning</strong>, take action, and evaluate themselves. From OCR pipelines enhanced by LLMs to agentic workflows that make decisions and improve with feedback, <strong>your code will help turn raw visual data into usable intelligence </strong>— at scale, and in production. </p><p>And the best about it? Your role has a <strong>direct impact on making food more affordable for millions </strong>of people every day.</p><p> </p><ul><li>B<strong>uild and deploy multimodal AI pipelines </strong>combining OCR, computer vision, and LLMs to extract structured data from images and photos</li><li><strong>Design agentic AI systems </strong>that dynamically generate prompts, invoke tools, and make decisions based on visual content</li><li><strong>Develop evaluation frameworks </strong>for AI pipelines and agentic systems, including synthetic simulations, automated feedback loops, and performance benchmarking</li><li><strong>Optimize OCR and visual content parsing</strong> for challenging real-world inputs using tools like Tesseract, LayoutLM, Donut, or TrOCR</li><li>Work closely with software engineers to seamlessly integrate AI features into our production systems. Design and maintain scalable infrastructure for LLM inference, API serving, and orchestration.</li><li>Implement comprehensive logging, observability, and monitoring for AI applications in production to ensure reliability and performance.</li></ul><h3>Qualifications</h3><ul><li>3+ years of hands-on experience in <strong>applied AI/ML</strong>, ideally in computer vision, document/image understanding, or NLP. Practical knowledge of <strong>image preprocessing</strong> (denoising, deblurring, segmentation) and pipeline optimization</li><li><strong>Experience integrating AI models</strong> into real-time or batch applications (e.g., bots, assistants, search).</li><li>Strong software engineering background with experience in APIs, microservices, and distributed systems.</li><li>Familiarity with <strong>vector databases</strong> (e.g., FAISS, Weaviate, Pinecone), embedding strategies, and retrieval-augmented generation (RAG) and tools like <strong>Langfuse, Grafana, or OpenTelemetry</strong> for observability.</li><li>Experience designing or contributing to <strong>AI agents evaluation systems</strong>, including prompt testing, output validation, synthetic data generation, or simulation-based evaluation.</li><li>You are a pragmatic engineer who understands what is needed to get things done in a collaborative manner. You’re a self-organizing, proactive person eager to work in a fast-paced, fault-tolerant, and agile environment, you unblock yourself, ship code quickly, and iterate to improve</li></ul><h3>Additional Information</h3><ul><li>Familiarity with <strong>judge models</strong>, human-in-the-loop feedback, or agent safety validation</li><li>Understanding of <strong>prompt engineering</strong> for visual contexts and multimodal agents</li><li>Experience building <strong>autonomous workflows</strong> with frameworks like LangChain, AutoGen, or CrewAI</li><li>Background in delivering AI-powered features inside real-world web or mobile applications</li></ul><p>We believe diversity and inclusion are key to creating not only an exciting product, but also an amazing customer and employee experience.
