COMPANY: http://AssessUp.com is the first unbiased platform to detect and promote talented professionals.

We provide individual users with a freemium online application to:

• Give confidential professional reviews on people they have worked with (while respecting everyone’s privacy).
• Get their skills validated by others and their profile picked up by recruiters.
• Discover the reviews given on existing or potential colleagues who are using the website.

We crowdsource the questions creation while avoiding any personal or defamatory comment, so that we are able to create customized, nuanced and relevant questionnaires for every profile.

We offer our corporate customers a disruptive recruitment tool where only checked and vetted professionals are selected.

In addition, we will sell software as a service to companies for their employee performance assessment needs, leveraging our technology, algorithms and database of questions (Performance Management System).

POSITION: Initially a solo project of a trader escaped from the City, http://AssessUp.com is now online in its Alpha version. As a Rails / Ember developer, you will join a team composed of at least one business developer and the original founder (technical background).

This is a complex and ambitious project:

• Intensive use of hashing & encryption (passwords, private keys locally for name & identities) for legal and security reasons (cf https://www. http://assessup.com/public/technology).
• Offline mode (Ember-data with two stores).
• Points, levels, grades, reputation, tags everywhere, crowdsourced and customized assessment questionnaires based on profiles’ tags.

The website is already built with all the main features, hopefully using a well-structured code. We now need to improve, consolidate, optimize, refactor, test it.. and launch it.

The current stack is: Back end: Rails 4, PostgreSQL + Redis, Resque, ActionController::Live / short polling, cloudfront / S3, Heroku hosting, git. Front end: Ember 1.13 + Ember Data with offline mode (two stores), Bootstrap 3, crossfilter.js + a bit of d3js (more to come).

We would like you to bring at least some of those skills:

Proficiency with Rails, + design / UX skills, growth hacking, experience with job boards, experience with developing APIs for third parties, Rails’ Action Cable or other WebSockets, SEO, mailers, payment systems, web apps in WebView, code optimization and testing, testing, testing..

The position is mostly to focus on the Rails API, but an experience working with Ember would be a plus: Ember 2.0, Ember Data, web workers for Ember Data serializations, Ember for mobile, pdf.js..

Our collaboration would start by working for some weeks on a predefined set of tasks to familiarize yourself with the project (with equity + cash compensation), followed by a meaningful cash + equity package.

We are an early stage startup, and although we should be able to pay you a competitive salary, we are aiming for someone as passionate about the project as we are, a strong and sharp profile, focused, hard-worker and independent, dedicated to the project and able in the future to manage their own team. Remote is possible, better to be able to travel regularly to (West) London. Full-time position, no contract.

This is a unique opportunity to join an ambitious project right before its release. We are a lean startup with a disruptive business model, a unique technological advantage embedded in the current platform, and a potential for strong and diverse revenue sources.
