Company: A pre-revenue start-up focused on developing an IIoT (Industrial Internet of Things) system which monitors the performance of industrial heat exchangers (HXs). HXs are used in almost every industry, and due to operational inefficiencies, cause about 1% of world greenhouse gas emissions. Our objective is to deploy a technology that can solve this problem together with an IIOT system to measure ongoing performance and GHG reductions. We have the system components that gets the data to the cloud. We need help building the web-based display of the data that is obtained. Project description: Looking for a full-stack developer to create a web-based application for users to login and view real time sensor data displayed through several graphs and other visualizations. Job will require working with an external API to retrieve time series data, creating a basic user management system to control access, and building an attractive user interface to display and manipulate the data. Site will likely require a local database to store information but the amount of information from the sensors is relatively small (approximately 30-60 sources sending numerical data and updating every ~10min). There are a small number of data inputs per HX; typically two temperature measurements, one flow measurement, and one pressure measurement. Once the data is received, it needs to be converted into a ‘dashboard’ display for the factory manager. We envision that the dashboard will show the 'basic data' about each heat exchanger (inputs provided manually at the start of the monitoring process such as number of plates, surface area, etc - data that doesn’t change) and graphs showing the data from the sensors over time (so the factory manager can see improvements/declines in performance). The sensor data and basic data will also need to be used in a straightforward mathematical calculation to produce one additional data set, the heat transfer coefficient for the heat exchanger (which is the ultimate measure of HX thermal efficiency). To begin, we need a rudimentary, simple, prototype system without any big effort on design or aesthetics — something that we can show to users to give them the idea of the information that will be available rather than what the final product will look like. After we have enough customer input then we will do a redesign for aesthetics and to incorporate other features like automated email alerts when data values reach a certain value, etc. Key Qualifications Excellent UI design skills and experience building different types of data visualizations with javascript Familiarity working with external APIs General backend development experience (Such as Python or Ruby on Rails but no particular preference) To begin
