(HIRING)Automation Engineer Wanted — n8n Core Role — Restaurant Tech Startup

Jobs
1

RestaurantFlow OS is a revenue automation platform for independent restaurants. We intercept booking data from OpenTable and SevenRooms, run it through a workflow n8n automation layer, and personalise every guest interaction based on visit history.

The system architecture is complete. We have a full technical master spec covering every workflow, every data flow, every edge case and every error state. We are not asking someone to design this — we need someone to build it precisely, with clean error handling, idempotency on every inbound webhook, and a Loom walkthrough per workflow group.

The Stack You Connect

  • Supabase
  • GHL
  • Printnode
  • openweatherapp

The Architecture Principle

Every workflow validates restaurant_id as step one. Scheduled workflows loop through active restaurants one at a time — no state bleeding between clients. Idempotency checks on every inbound webhook using unique_event_id logged to Supabase event_log. HMAC-SHA256 signature validation on every inbound webhook. Error handler WF-20 catches all failures, logs full context, sends admin alert. This is not MVP code — it is production architecture from day one.

WHAT WE ARE OFFERING

:check_mark: Paid build fee for the initial workflow implementation — scoped and agreed upfront

:check_mark: Ongoing paid retainer — every new workflow, integration and optimisation as the platform scales

:check_mark: Equity stake for the right long-term partner

:check_mark: Your architecture credited in technical documentation and investor materials

A product that is genuinely novel — no existing platform does what RestaurantFlow does

Who We Are Looking For

→ Proven n8n experience with complex multi-branch logic, webhook handling, API integrations and error handler patterns.

→ Comfort building against a precise written spec — this is a defined architecture, not a creative brief.

→ Ability to deliver Loom walkthroughs explaining every workflow decision.

→ Ideally: experience with Supabase or PostgreSQL APIs, GHL API calls, or hospitality/restaurant technology.

Reply or DM — tell us the most complex n8n workflow you have built and what made it hard.

The spec is ready. The clients are coming. The system needs to be built.

If you need I am available here:

I am one of top 50 verified template creators:

I am also capable of building custom community n8n node too:

  1. https://www.npmjs.com/package/n8n-nodes-pdfbro
  2. https://www.npmjs.com/package/n8n-nodes-ocrbro
  3. https://www.npmjs.com/package/n8n-nodes-ttsbro

Apart from that I’m also a full-stack developer with the right Gen AI experience, which makes me a solid plus for your team[but right now only vibecoding]

Check my recent gen ai projects… I built a native Android automation agent too. It’s worth a look:

I can build complex AI automations directly in code, not just inside n8n

I recently started posting my n8n work on YouTube with explanations:

You can schedule a quick call with me: https://cal.com/abhi.vaar/n8n

Fun fact… I even made an n8n workflow to find a few n8n project leads for myself so I truly believe in what I do…

I started asking My recent clients for honest feedbacks so here is one testimonial: https://www.youtube.com/watch?v=TqBy3SVCHgQ&list=PLAJltY5bp6yiZ3sFBjm7bfrkLXSGtJX8m

Here is my linktree: iamvaar | X | Linktree

And I am also capable of building gohighlevel automations and other CRM’s too, here are my recent gohighlevel integrated automation videos:

  1. https://youtu.be/eZ3t7PfXFho
  2. https://youtu.be/nSJzOB9JZlY

And I also built low latency voice appointment scheduler with live ai avatar[in code]:

I built AI search visibility tracker[I am capable of building complex web scraping automations in python too]:

And done many other big projects too which are under NDA’s so technically I can’t reveal them.

Hi Helder, Welcome to n8n Community :waving_hand:

This is a strong spec, especially the focus on idempotency + isolated multi-tenant flows.

I’ve built similar n8n systems handling webhook ingestion → validation → processing → logging with strict error handling and no state leakage across clients.

Recent builds: • AI voice + API workflow orchestration

https://www.upwork.com/freelancers/~0122761e4734295f4b?p=2038586338272239616

• Multi-channel automation (CRM + data + reporting flows)

https://www.upwork.com/freelancers/~0122761e4734295f4b?p=2039118619839795200

• Shopify backend workflow system

https://www.upwork.com/freelancers/~0122761e4734295f4b?p=2039336822638325760

Question: – how are you currently structuring event_log in Supabase for deduplication and replay safety?

Happy to take a workflow group and map it cleanly.

I’ll DM you as well.

This sounds like exactly the kind of build I do. Two things from your spec stood out: idempotency on every inbound webhook with unique_event_id logged to a Supabase event_log, and HMAC-SHA256 signature validation. That’s the architecture I default to — I’ve shipped it on a SaaS (CannaSpy) and on StoryStar’s AI generation pipeline, both with Supabase as the source of truth.

Fast questions before I send a structured proposal:

  1. Roughly how many workflows in the initial build scope?
    1. Is the spec doc shareable under NDA so I can size accurately?
      1. Self-hosted n8n or n8n Cloud?
    3. I can share Looms of past Supabase + n8n + Stripe builds. Happy to start with a paid 1-workflow trial so you can validate the build quality before committing to the full retainer.
