Argentina onlyWe 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 Do
- Own the technical architecture — backend, frontend, infrastructure, and AI integration
- Write code daily — build the critical systems yourself
- Make stack and design decisions that will shape the product for years
- Set the standard for code quality, testing, and engineering discipline
- Integrate LLMs and AI workflows deeply into the platform
- Work directly with founders on product direction and technical roadmap
- Create clarity and structure in an environment that doesn't have perfect specs
- Mentor and guide the other developers technically
Must-Have Skills
- Strong TypeScript — you've built production systems with it
- Deep Node.js backend experience
- Solid React frontend experience
- SQL and database design — you know how to model data properly
- Experience with TypeORM, Zod, or similar tools
- Ability to reason about full-stack architecture
- Experience building with or integrating LLMs and AI systems
- Strong engineering fundamentals — clean code, maintainability, system design
Bonus Skills
- Experience at early-stage startups
- DevOps and infrastructure experience
- Background in conversational AI or workflow automation
