We're looking for a *Senior Lead Engineer* who can own major parts of this platform, lead a team, and help define what the future of industrial B2B SaaS looks like.**What You’ll Do1\. Lead Architecture \& System Design** * Own architecture for a large\-scale, multi\-tenant B2B SaaS platform. * Make key decisions around Next.js (frontend) and Nest.JS (backend) with strong opinions on clean, consistent patterns. * Ensure scalability, high\-performance data flows, and clean boundaries between services (auth, real\-time messaging, market directory, AI workflows, etc.). **2\. Guide a Team of Engineers** * Provide code reviews that make junior and mid\-level engineers better without slowing them down. * Establish engineering standards, patterns, and documentation that keep the codebase clean and predictable. * Collaborate with international teams (U.S., Paraguay, Pakistan, etc.) and maintain high output and accountability. **3\. Work Directly With Customers \& Product** * Join customer discovery calls to understand workflows and pain points. * Translate real customer language into product requirements, lightweight specs, and actionable engineering tasks. * Make sure what we build matches what customers actually need. **4\. Deliver Features End\-to\-End** * Work across the full stack to build high\-quality product features and internal tools. * Own the delivery timeline — plan, break down work, and ensure the team ships on schedule. * Help design UI/UX alongside product for clarity, speed, and professional polish. **5\. Integrate AI in Real Workflows** * Use agentic AI tools (Claude Code, GPT\-5 Agents, etc.) to improve speed and code quality. * Help architect AI\-driven modules like FlowBot, agent orchestration, document parsing, and knowledge retrieval. * Understand embeddings, RAG, message buses, workflow engines, and how AI fits into a real production system. **Tech Stack You’ll Work In**You don’t need every single one, but you must be fully fluent in the star components:**Core** * **Next.js** (App Router, server components, streaming, performance patterns) * **Nest.JS** (modular monolith structure, dependency injection, providers, guards, interceptors) * **PostgreSQL / Drizzle ORM / Neon** **AI / Agentic Tools** * Claude Code / GPT\-5 agents * LangChain or equivalent * Vector DBs (Qdrant, Pinecone) * Retrieval and workflow orchestration **Who You Are**This is not a junior or mid\-level role. You are: * **A seasoned engineer with 10\+ years of experience** shipping production SaaS products. * **A systems thinker**, able to zoom out to architecture and zoom in to refactor a messy function. * **Strong with Next.js and Nest.JS** at a professional, battle\-tested level. * **Comfortable leading teams**, structuring work, setting direction, and holding people accountable. * **A product\-minded engineer**, not a ticket\-taker — you think in terms of customer outcomes. * **AI\-forward**, experimenting with agentic tools, using them to improve speed and quality. * **Opinionated about code quality**, structure, and maintainability. * **Comfortable in fast\-paced environments**, where speed, clarity, and consistent output matter. **Nice to Have** * Experience with B2B SaaS, especially platforms with network effects * Experience with collaboration tools, chat/messaging infrastructure, or real\-time systems * Experience designing multi\-org, multi\-role permission systems * Experience with geospatial data or map libraries (MapLibre, PostGIS) * Experience leading distributed teams **Why Join Flow RMS / FlowConnect** * You’ll help build a **new category**: the coordination layer for the industrial supply chain. * You’ll work with **founders who ship quickly**, think clearly, and operate at a high standard. * You’ll directly shape how manufacturing reps, distributors, and manufacturers collaborate nationwide. * You’ll lead a team building a platform used across the entire industry. * You’ll be part of a fast\-growing company that reinvests heavily in product development.
