Full Stack Engineer (offline)

You will need to describe the largest, most complex project you’ve worked on, and explain your role in that project. Then tell us how comfortable you are working with React, Python, and databases. This role requires a lot of crossing over between front-end, back-end, and databases.

On a scale of one to 10, rank the following, and also provide the years of experience you have with production code:

ReactJS
Python
Django
Web-crawling
Database query optimizations
JavaScript

High Level
At a high level, we’re looking for an engineer who has the following qualities:

You should have a sound understanding of standard Computer Science algorithms, and get excited when you can solve difficult problems elegantly.
You should be detail-oriented, someone who uses real data to guide your design decisions.
You should be a practical engineer who is able to think about the benefits and risks of a given solution and propose thoughtful options in front of the team.
You should have experience with both front-end and back-end so you can participate in a variety of product discussions.
You should have great communication skills (able to get on voice calls), be responsive and available, and accountable since it’s a fully remote position.
You’ll work closely with our two engineers and our two co-founders on a day-to-day basis. Once on-boarded, you’ll have the opportunity to work on critical features. Once solved, you’ll be able to see your code live on production and being used by hundreds of our clients.

Extra Details
WHAT YOU’LL BE WORKING ON
You’ll be working on our website which provides a highly-scalable SaaS platform to clients to facilitate marketing campaigns. It contains three primary components:

a large, searchable database of influential media profiles (140,000,000 and growing), along with detailed profiles on each.
campaign management (which is comparable to a CRM combined with a more complicated version of project management software)
campaign reporting (which contains a lot of data visualizations)

JOB DESCRIPTION
As a full-stack developer working on this project you’ll be hands-on with all three areas of the site. To give you a better idea of what you’ll be working on… we’re currently wrapping up our V1 of the product and getting ready to start on V2, so this is a really exciting time to join. The start date for V2 is set for the beginning of August. By joining at this time, you’ll have ownership over certain areas of the product. You’ll be able to write your own code, rather than fixing up years worth of older code. Yay!


Our stack is Angular/React and Python/Django. We use ElasticSearch for implementing fast, text-based searches. Our application is deployed on Heroku and we use Github issues with ZenHub to manage tasks. Our back-end tasks are implemented using standard RabbitMQ server and celery. We currently use around 16 back-end servers. We use PostgreSQL to store 2TB of data. (edited)

Styling: CSS, LESS, JSS
JavaScript frameworks: ReactJS, Angular 1.2 (legacy code)
JS-based build tools: Webpack
