Our client is a fast-growing, founder-led AI software company building a modern social media platform for businesses, creators, and agencies. The product helps users create, schedule, automate, and scale high-quality social content using AI-powered workflows.
This is a strong opportunity for an engineer who wants to work close to an experienced founder, build meaningful AI product features, and help shape the architecture of a growing platform rather than simply maintain another standard SaaS application.
About the Role
We're looking for a hands-on Lead Full Stack Engineer to help build and scale modern, AI-powered applications where LLMs, automation, agents, and intelligent workflows are core to the product.
You'll lead both technical direction and hands-on delivery, working across backend, frontend, cloud infrastructure, AI integrations, and product architecture. This role is ideal for someone who can think like a builder, move quickly, make smart engineering decisions, and help the team use AI to ship faster without compromising quality.
What You'll Do
- Lead development of full-stack systems using Python and modern frontend frameworks such as React or Angular
- Design, build, and ship AI-powered product features using LLMs, RAG, embeddings, agents, and AI APIs
- Architect scalable backend services, APIs, data flows, and distributed systems
- Make key technical decisions around system design, architecture, tooling, cloud infrastructure, and AI model usage
- Build reliable integrations with third-party platforms, AI providers, social media tools, and internal product systems
- Improve performance, security, observability, scalability, and reliability across the platform
- Oversee cloud infrastructure across AWS, Azure, or GCP
- Guide engineers on best practices across code quality, architecture, testing, reviews, and delivery
- Help the team adopt AI-assisted development workflows to improve speed, quality, and productivity
- Work closely with the founder and product team to turn ideas into production-ready features quickly
What We're Looking For
- 5+ years of full-stack software engineering experience
- Previous experience leading technical decisions, mentoring engineers, or owning major product areas
- Strong backend experience with Python, ideally using Django, FastAPI, Flask, or similar
- Strong frontend experience with TypeScript and React or Angular
- Proven experience building and scaling APIs, backend services, and production-grade systems
- Experience with cloud platforms such as AWS, Azure, or GCP
- Strong database experience across SQL and/or NoSQL systems
- Experience shipping AI-enabled features into real applications, not just prototypes
- Strong product mindset and ability to balance speed, quality, scalability, and user impact
AI Experience
- Experience integrating AI APIs into real, production-grade applications
- Familiarity with RAG, embeddings, vector search, agents, or similar AI application patterns
- Comfortable using AI development tools to improve speed, code quality, testing, and delivery workflows
- Understanding of common AI limitations and risks, including hallucinations, latency, cost, accuracy, data privacy, and reliability
- Ability to think beyond simple API integration and help design practical AI-powered product features that create real user value
Nice to Have
- Experience with model tuning, prompt optimization, or open-source AI tools
- Exposure to AI monitoring, evaluation, observability, or analytics tools
- Experience building AI features for marketing, content creation, automation, or social media platforms
Working Conditions
- Remote work setup
- Independent contractor engagement
- US working hours
