Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Founding Engineer: Consumer Mobile (React Native) - **Company:** CLERA, LLC - **Location:** San Francisco, CA, United States - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Apple IOS, Big Data, Elasticsearch, Interaction Design, Python (Programming Language), Open Source Technology, Recommender Systems, TypeScript, Web Applications, Real Time Systems, ReactJS, Large Language Models, Snowflake, Backend, React Native, Front End Software Development, Virtual Agents - **Published:** June 9, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=f03c48856c26de2a ## About the Role Do you have experience in Web applications?, * You've built something technically ambitious end-to-end * Exceptional problem-solving ability (systems, math, or both) * You move fast and don't need much structure * You care about taste - not just if something works, but how it feels * You like hard, ambiguous problems Backgrounds we often see: * Competitive programming or advanced mathematics background * Early engineers at high-bar companies * Strong open source contributions ## Description You'll operate as a founding engineer, owning problems end-to-end. This is an in-person role in San Francisco working on an AI-powered map and messaging product that helps people discover places and events, and connect with friends. The company has built one of the largest structured indices of places and events in the real world, and is now building a social product experience around that index. What You'll Do * Design and ship product and systems from zero to production * Work directly with founders on product and architecture decisions * Make decisions that shape core systems, not just contribute to them * Move across the stack as needed - frontend, backend, infrastructure, and AI Example problems you might work on: * Ranking recommendations using embeddings, structured data, and social signals * Optimizing search and vector operations to sub-100ms latency across large datasets * Building real-time systems for chat, presence, and location features * Designing map display algorithms that determine what deserves attention * Building AI agent pipelines that plan queries and synthesize informed answers * Structuring unstructured web data to power novel experiences Areas of Focus: Application Engineers (Full-stack): Build fast, expressive interfaces across mobile and web. Work on rendering performance and interaction design. Own features end-to-end from UI to backend. Typical tools: TypeScript, React, React Native, iOS/Android, backend systems in TypeScript. Data / AI Engineers: Build the intelligence layer behind the product. Work on search, ranking, pipelines, and agent systems. Design systems that operate over large-scale, messy real-world data. Typical tools: Python and/or TypeScript, Elasticsearch, Snowflake, LLMs, embeddings, retrieval and recommendation systems. ## Related Videos - [Alibaba Big Data and Machine Learning Technology](https://www.wearedevelopers.com/videos/37-alibaba-big-data-and-machine-learning-technology) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [It's a Great Time to be a Builder: Leveraging AI for Good](https://www.wearedevelopers.com/videos/100042-it-s-a-great-time-to-be-a-builder-leveraging-ai-for-good) - [PySpark - Combining Machine Learning & Big Data](https://www.wearedevelopers.com/videos/44-pyspark-combining-machine-learning-big-data) - [There's an app for that - on the role of cross platform development in the app development ecosystem](https://www.wearedevelopers.com/videos/278-there-s-an-app-for-that-on-the-role-of-cross-platform-development-in-the-app-development-ecosystem) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 118 - not a total recall](https://www.wearedevelopers.com/magazine/452-dev-digest-118-not-a-total-recall) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [Dev Digest 139 - Soft and hard queries](https://www.wearedevelopers.com/magazine/487-dev-digest-139-soft-and-hard-queries) - [16 Best Free React UI Libraries in 2025](https://www.wearedevelopers.com/magazine/148-16-best-free-react-ui-libraries-in-2025)
