Business Analyst / Product and QA Lead for Water Subscription Platform

About the project
We are building a new website and platform for a premium water delivery company. Customers subscribe to regular water deliveries. They pay a deposit for reusable water containers and return them later.
The platform will include:
A public website and product catalog
A tool to check if delivery is available in a ZIP code
A subscription builder (products, sizes, quantities, frequency, discounts, deposits)
Online payments and a customer account area
Delivery tools: delivery lists for drivers, a mobile-friendly driver app, and delivery photos
Inventory tracking and demand planning - to track containers and deposits etc. (given, returned, damaged, lost, refunded)
Automatic customer messages (reminders, delivery confirmations)
Connections to a payment provider, GoHighLevel (CRM), and QuickBooks

Tech stack: Next.js, TypeScript, Tailwind, Supabase (database, login, file storage), Vercel, GoHighLevel, QuickBooks, Payments - Card Connect with Recurring billing.

We already have a prototype and a first draft scope document. These are a starting point. Your job is to turn them into a clear, complete plan.

You will be the main link between the client, and the team - the designer, the developer.

What you will do
This role combines 2-3 roles in one: Product/Business Analyst, QA and potentially , Project Manager. We want one person who owns the requirements, the plan, and the quality.

1. Lead the Discovery phase (first 1-2 weeks)
Run meetings with the client to turn ideas and notes into clear, written requirements
Get clear answers on the tricky business questions
Map out how each integration (payments, GHL, QuickBooks) should work, step by step
Deliver: a product backlog, a data model (with Alex), a list of risks, and a clear MVP scope (what is included and what is not) and estimates
2. Define and prioritize the product
Help decide what belongs in the MVP and what can wait.
Write user stories that are clear enough for the developer to build without extra meetings
Keep the backlog organized and up to date; run planning meetings and demos
If something doesn't fit the plan, say so early, explain why, and suggest an alternative
3. Manage the project
Keep track of the plan, deadlines, and what depends on what
Report progress weekly to us and the client
Help the developer get what they need: decisions, content, images, account access
Be honest with the client if a deadline is at risk
4. Own quality (QA)
Write test cases based on the requirements
Test the website and app
Focus on the tricky cases, not just the easy ones: payment errors, duplicate charges, subscription changes, deposit calculations, and permissions
Keep track of bugs with clear steps to reproduce them
Plan and run testing with the client before launch
Check basic accessibility on customer-facing pages

What we're looking for
Must have
4+ years of experience as a Business Analyst or Product Owner on custom web projects, including some QA or delivery management
Experience writing requirements, product backlog, etc.
Strong written English (you'll write most requirements and talk directly with a US client)
Comfortable with technical ideas: databases, APIs, webhooks, and user permissions. You don't need to code, but you should be able to question a technical design
Hands-on experience with manual QA, including testing APIs (e.g. with Postman)
Able to work independently in a small team
Use AI consciously to improve BA and QA efficiency
Nice to have
Experience with e-commerce, delivery, or logistics platforms
Experience running Agile projects (Scrum or Kanban) as the person responsible for the plan
Experience integrating a US payment provider with recurring billing (CardConnect, Stripe, or similar)
Experience with GoHighLevel (or other CRM) or QuickBooks
Familiarity with Next.js and Supabase
Experience with automated testing (Playwright or other) even with AI
Comfortable reviewing designs in Figma
You are a good fit if you:
Write things down. If a decision isn't written down, it doesn't count
Are comfortable telling a client that something won't fit in the MVP
Ask questions instead of guessing
Care that the product works well in real use, not just that a task is marked "done"
