Components are styled using Tailwind CSS. - Supabase: The application uses Supabase as a real‑time database and authentication layer, replacing the traditional Node/Express + Postgres setup. - Node.js (API routes): Certain backend tasks run in Node.js through Next.js API routes, including cron jobs and integration scripts. - AI / ML integration: The platform integrates with GPT‑style APIs to generate marketing content, reply to reviews and suggest campaigns. There is also internal model training infrastructure for fine‑tuning smaller models. - Analytics & Charts: We use charting libraries (e.g., ApexCharts) and custom dashboards to display ROI, conversion rates and multi‑channel campaign performance. - Cloud & DevOps: Supabase hosting for the database and API functions; Vercel or similar service for the Next.js frontend; CI/CD pipelines set up for automatic deployments. - Future plans include adding an event‑driven architecture with message queues (e.g., using Supabase Realtime or a dedicated MQ service), implementing vector databases for storing embeddings, and further embracing serverless functions. ## Responsibilities - Lead full‑stack development: Own the architecture and implementation across the Next.js frontend, Supabase backend and Node.js API routes. Design responsive UI components, manage state with React hooks/context and ensure scalable database design. - AI & ML integration: Build and maintain pipelines that call LLM APIs, preprocess text, store embeddings and fine‑tune models. Evaluate new AI tools to enhance personalization, recommendation and summarization features. - Cloud infrastructure & DevOps: Configure deployments on Supabase and Vercel (or equivalent), manage environment variables, set up automated testing and ensure reliable CI/CD workflows. - Data security & compliance: Implement best practices for authentication, authorization and data privacy (GDPR, HIPAA where applicable). Monitor Supabase RLS policies and maintain secure API keys. - Collaborate closely with the founding team: Translate product requirements into technical designs, iterate quickly based on user feedback and help define the product roadmap. - Recruit & mentor: As the team grows, hire and mentor developers and data engineers, establishing coding standards and documentation practices. ## Qualifications - 5+ years of full‑stack development experience, including advanced proficiency in React and Next.js, modern JavaScript/TypeScript, and RESTful API design. - Experience with serverless and real‑time databases, ideally Supabase or Firebase, and familiarity with SQL and database schema design. - Hands‑on experience with AI/ML: integrating large language models via APIs, fine‑tuning models and working with vector databases or embeddings. - Cloud & DevOps familiarity: deploying on Vercel, AWS or GCP; understanding of CI/CD pipelines and environment configuration. - Strong communication skills and the ability to collaborate with non‑technical co‑founders and early customers. - Start‑up mindset: comfortable with ambiguity, biased toward action and passionate about empowering small businesses through technology. ## Why join Market Engineer 360? - Co‑founder equity and a meaningful stake in a rapidly growing AI SaaS. - Ownership of the technical stack and architecture, with the freedom to innovate and implement best practices. - Mission‑driven team committed to democratizing marketing tools for small businesses. - Remote flexibility with opportunities to shape company culture and future hires.
