Senior Software Engineer – AI Platform Engineering (Founding Engineer Role, Equity Only)

LaunchFamily is a mission-driven company that empowers families to take control of their children’s growth, learning, and well-being through intelligent systems. We’re building the world’s first AI-powered Family OS.

Parents juggle 50+ decisions a day, meal planning, homework help, emotional check-ins, and schedules. Most 'family apps' are just glorified to-do lists. We're building something different: an AI that actually understands your family's rhythm and proactively helps you stay ahead.

We’re looking for a Senior Software Engineer who can architect and scale the AI backbone behind this system, from retrieval-augmented generation (RAG) pipelines to multi-agent orchestration, and intelligent data flows that make our assistant truly personal.

This is an equity-only opportunity during the beta phase as we prepare for seed funding. Our founders have led and co-founded ventures that collectively raised over $100M and have had successful exits. You’ll be joining at the earliest stage to define the foundation of something transformative.

What You’ll Build

AI Infrastructure (40%)

• Design and implement multi-agent systems using the OpenAI Agents SDK for domains like scheduling, meal planning, education, and emotional guidance.
• Build RAG pipelines with hybrid search (vector + structured), using PostgreSQL + pgvector, Redis, and Embeddings APIs to ground AI responses in trusted family data.
• Develop contextual memory systems to store, retrieve, and rank user-specific insights (daily logs, family routines, past conversations).
• Experiment with function calling, tool-use orchestration, and chain-of-thought prompting to create agents that reason and collaborate.
• Optimize token usage, caching, and model routing to strike a balance between personalization, performance, and cost.

Core platform Engineering (30%)

• Design modular, scalable NestJS services (Fastify) with Drizzle ORM and PostgreSQL.
• Build multi-tenant APIs and workspace logic to support apps built on Launched (our low-code builder).
• Manage async workflows with BullMQ for real-time event processing, streaming responses, and queue-based pipelines.
• Maintain end-to-end type safety with shared TypeScript models across backend and frontend.

Frontend Portals (30%)

• Develop core interfaces for Launched, enabling creators to train and deploy AI chatbots, tools, and apps using the same infrastructure that powers LaunchFamily.
• Contribute to our Next.js-based assistant UI with real-time streaming, context management, and AI-driven visualizations.
• Collaborate with product to prototype new AI-driven experiences, from proactive notifications to visual family insights.

Tech Stack

AI Layer

• Agents SDK (core), LangChain / AutoGen (support)
• RAG Stack: PostgreSQL + pgvector, Redis, OpenAI Embeddings
• Model Integration: GPT-4o, custom fine-tuned models, retrieval interfaces
• Evaluation & Testing: structured outputs, JSON schema validation, prompt benchmarking

Core Platform

• Backend: NestJS (Fastify), TypeScript, Drizzle ORM, PostgreSQL
• Frontend: Next.js, TailwindCSS, WebSockets
• Infrastructure: Docker Compose, Railway / Vercel, CI/CD, Jest

What We’re Looking For

• 5+ years of full-stack engineering experience (TypeScript preferred)
• Strong knowledge of LLM integration, RAG systems, or AI agent frameworks
• Solid experience designing event-driven architectures and real-time systems
• Deep understanding of database design, query optimization, and data retrieval patterns
• Proficiency with prompt engineering, structured output design, and context management
• Experience deploying AI-based APIs in production environments
• A belief in simplicity, scalability, and testable design
• Passion for meaningful products that genuinely help families

Nice-to-Have

• Familiarity with LangGraph or AutoGPT
• Experience with voice, multimodal inputs, or personalized memory systems
• Prior work in consumer AI, health/wellness, or education platforms
• Startup or co-founder experience

Your Path Forward

This is a founding engineer role with a clear trajectory to technical leadership.

As we grow from beta → seed → Series A, you'll naturally evolve from hands-on architect to CTO or VP of Engineering — building and leading the team you wish you’d joined.

We’re not hiring someone to “fill a seat until we find a CTO.”

We’re hiring the person who becomes that CTO.

Why LaunchFamily

• Build with purpose, every feature helps real families live with less chaos and more connection.
• Work with experienced founders who have scaled and exited successful ventures.
• Be hands-on with cutting-edge AI, from architecture to agents.
• Fully remote and asynchronous, we value autonomy and craftsmanship.
• Earn meaningful equity in a venture positioned for growth and long-term social impact.

Compensation

This is an equity-only role until seed funding or milestone revenue. As we scale subscriptions, compensation will expand alongside shared success.

If you’re an AI-native engineer who thrives at the intersection of LLMs, data systems, and real-world impact, join us to build the foundation of the Family OS.
