Job Description: We are looking to hire our Senior Technical Lead — the person who will own our technical architecture and set the engineering standard for the company. You'll be working with two other developers, but you are the senior engineer. You'll make the key technical decisions, build the core systems, and establish how we build software. This is not a management role — you'll be hands-on, writing code daily, and leading through technical excellence. This is a startup. That means ambiguity, pressure, direct access to founders, and real responsibility. You'll need to be highly driven and deeply interested in either AI systems, senior care technology, or both. It's a demanding role, but you'll work with smart people who care about the mission and you'll get direct exposure to how US startups actually operate.What You’ll DoOwn the technical architecture — backend, frontend, infrastructure, and AI integrationWrite code daily — build the critical systems yourselfMake stack and design decisions that will shape the product for yearsSet the standard for code quality, testing, and engineering disciplineIntegrate LLMs and AI workflows deeply into the platformWork directly with founders on product direction and technical roadmapCreate clarity and structure in an environment that doesn't have perfect specsMentor and guide the other developers technicallyMust-Have SkillsStrong TypeScript — you've built production systems with itDeep Node.js backend experienceSolid React frontend experienceSQL and database design — you know how to model data properlyExperience with TypeORM, Zod, or similar toolsAbility to reason about full-stack architectureExperience building with or integrating LLMs and AI systemsStrong engineering fundamentals — clean code, maintainability, system designBonus SkillsExperience at early-stage startupsDevOps and infrastructure experienceBackground in conversational AI or workflow automation
