FullStack Developer (Node + React) - LatAm Candidates!

Location: LatAm (Remote)

Contract: Part-time possible; flexible hours

Compensation: Up to US$53/hour (depending on hours / seniority)

About Our Client

Our client is a cutting-edge startup focused on building AI-driven solutions. We’re at a point where we want to go beyond individual contributor roles, increasing our architecture & advisory strength. We want someone who's been a Tech Lead or CTO (or similar), ideally with recent experience at a FAANG or prominent AI company (OpenAI / Anthropic etc.).

What You’Ll Do

As a senior technical advisor / lead within a full-stack capacity, you will:

• Architect, guide, and build core product features using Node.js (Nest or Express) on the backend, and React + Next.js on the frontend.
• Act as a mentor/advisor to other engineers, reviewing architecture & code, raising quality and standards.
• Assist in shaping the tech roadmap with strategic input, especially from someone who’s worked at scale or in high-growth AI environments.
• Take ownership for specific modules or systems (backend and/or frontend) and ensure robust, maintainable, scalable code.
• Participate in hiring, architectural design reviews, code reviews, establishing best practices.
• Potentially reduce overhead by advising on infrastructure choices, performance optimizations, and system stability.

What We’Re Looking For

Must-Haves:

• 5-7+ years of solid engineering experience, including full-stack work with Node.js (Nest or Express) and React + Next.js.
• Previous role as CTO, Technical Lead, or similar leadership/architect capacity, with evidence of advising / decision-making responsibilities.
• Fluent English (C2) — able to communicate clearly, review technical designs, mentor strangers, etc.
• Experience in AI or high scale software environments, ideally worked in AI companies or at least in teams/products that leverage AI substantially.
• Strong software engineering fundamentals: good testing practices, clean architecture, performance, reliability.

Nice-To-Haves:

• Experience with FAANG or other elite AI orgs (OpenAI, Anthropic, etc.) in the past ~2 years.
• Exposure to building AI-centric features, LLMs, agent frameworks, or any similar generative systems.
• Familiarity with cloud infrastructure (AWS or similar), deployment pipelines, CI/CD, performance monitoring.
• Experience working in startups or fast-paced environments; comfortable with ambiguity, pivoting.

What You’Ll Get

• An opportunity to shift into a more advisory / leadership role, influencing product & architecture, not just coding.
• Flexible engagement: part time ok, remote work across LatAm or beyond.
• Competitive rate (up to US$53/h, depending on hours and impact).
• Being part of a fast-growing AI startup; your work will have high visibility and impact.
