Flow RMS is building FlowConnect — the real-time coordination and intelligence layer for the entire industrial supply chain.
FlowConnect combines AI, collaboration, network data, and operational tooling for manufacturers, reps, distributors, and associations. 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 InYou 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 AreThis 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.
