JOB OVERVIEW

About Us

---------- is the leading online destination for Native American powwow culture, running on WordPress with an event calendar that receives over 125,000 visitors per month. We send email through Kit (formerly ConvertKit) to a list of roughly 95,000 subscribers.

The Project

We want to build a custom service that automatically sends our subscribers a weekly email of upcoming powwow events in the locations they care about.

Here's how it needs to work:

Pull event data from WordPress. Our events live in an event calendar plugin on our WordPress site. The service needs to pull upcoming events (via the plugin's API/REST endpoints or database) including dates, locations, and event details.
Let subscribers choose their locations. Each subscriber should be able to select which U.S. states they want to see events from — and update those selections at any time. This preference data will be stored in Kit (custom fields and/or tags via the Kit API).
Generate personalized weekly emails. Every week, the service automatically generates and sends each subscriber an email containing only the upcoming events in their selected states, delivered through our Kit account via the Kit API (v4).
Run reliably without manual work. Once built, the weekly emails should go out on schedule with no hands-on effort from us.

Scope of Work

Design and build a web service that connects our WordPress event calendar to our Kit account
Build the subscriber-facing location preference interface (initial selection + ability to update later)
Implement the Kit API integration: managing subscriber custom fields/tags, and creating/sending the weekly broadcast emails
Build the email generation logic: filter events by state, format them into a clean email template, handle subscribers whose states have no events that week
Set up scheduling/automation for the weekly send
Provide documentation and a reasonable handoff so we can maintain or extend the system
Advise on the best architecture — we're open to your recommendations on hosting, stack, and approach

Required Skills & Experience

REST API integration — this is the heart of the project. Must show prior work integrating third-party APIs. Direct experience with the Kit (ConvertKit) API is a big plus but not required if you have strong general API experience
WordPress development — comfortable working with WordPress plugins, the WP REST API, and/or querying WordPress data. Experience with event calendar plugins (e.g., The Events Calendar, Modern Events Calendar) is a plus
Backend/web service development — PHP, Python, or Node.js; building and deploying a hosted service with scheduled jobs (cron)
HTML email — generating dynamic email content that renders well across email clients
Front-end basics — building a simple, clean preference-selection form for subscribers

Nice to Have

Experience with email marketing platforms and their APIs (Kit/ConvertKit, Mailchimp, ActiveCampaign, etc.)
Experience with Liquid templating (Kit uses Liquid for dynamic email content)
Experience building subscriber preference centers
Familiarity with webhooks for syncing data between systems

How to Apply

Please begin your application with the word "CALENDAR" in the first line. Then include:

A short introduction
Links or descriptions of 2–3 relevant projects — especially anything involving API integrations, WordPress, or email automation
A brief outline (a few sentences is fine) of how you would approach this project: what stack you'd use and how the pieces would connect
Your rate (hourly or fixed-bid estimate for the project) and availability

Applications that don't follow these instructions will not be considered.
