REMOTE (Worldwide) - Open Source Developer on Open edX - React, Python/Django, AWS/OpenStack (OpenCraft - Fully remote company)

Development specialized on the free software project Open edX, used by and in part developed by organizations like MIT, Harvard, McKinsey, and others, so you’ll have the opportunity to contribute to projects that are widely used and to be part of a thriving open source educational community. See edx.org, stanford.edu or fun-mooc.fr for examples of Open edX instances.

We are 27 senior developers, all working remotely from Europe, North & South America, Asia & Australia. The company is not affiliated with edX, but rather contributing and working with them on various projects. This is a full time position, where you would be able to work remotely from anywhere you want, as long as you have a good internet connection. : )

The Open edX platform is a large Python/Django codebase, with good code standards and architecture. You would work on different clients contracts using the platform. The clients list/references include Harvard, MIT, edX themselves, the French government, and various startups & universities currently running their own instances, or looking to create one. Tasks are very varied, from developing core platform features, custom exercises and tools for specific courses (XBlocks), customizing and deploying instances, working fullstack, operating our service infrastructure, improving our hosting platform, etc. You won't get bored here.

Most of your work is published as free software (Open edX is released under the AGPL license, which requires clients to release modifications under the same license), and you would also contribute to the free software project, pushing most of your developments upstream through pull requests, contributing features, documentation or help on mailing-lists.

We welcome applicants of all genders and ethnicities.

You can read more about how we work in our handbook, at https://handbook.opencraft.com/

Stack: Python/Django, Ansible, AWS/OpenStack, React, Debian/Ubuntu, MySQL, MongoDB, PostgreSQL, RabbitMQ, Redis, Elasticsearch, JS, HTML/CSS.

Nice to haves: Terraform, Vault, Packer, Prometheus, ELK, Docker, Android/iOS. We are building a modern infrastructure and having a strong DevOps presence on top of core software engineering skills is a big plus with us.

Interview process: a 30 minutes Hangout with a (simple) coding exercise.

Analytical Flavor Systems | Manhattan - NYC | Full-Time | Onsite | http://www.Gastrograph.com/ Positions: Full-Stack Engineer, Data Scientists, R&D Product Formulator / Scientist Overview: Gastrograph AI is an artificial intelligence platform for modeling human sensory perception of flavor, aroma, and texture to predict consumer preferences of food & beverage products. We help food and beverage companies develop new products, enter new markets, and optimize their existing brands. We're a diverse 12 person post Series-A startup. Application & Data Stack: Javascript, React & React Native, Java, GraphQL, Spark, R, postgres/MySQL, AWS

The Position(s)

_Data Science_: We didn't build a data science team to optimize our product's marketing spend, sales funnel, or client retention – we built a data science team to build our product. Our Data Science team develops new models and algorithms from scratch to make second-order inference on sparse data sets from non-representative samples that generalizes to the underlying target population. We rely on cutting edge models such as persistent homology, PU Learning, and metric learning to make predictions on non-eucldian human sensory data. We don't use tensor flow or pandas or keras as they are not a good fit for our problem space. We prefer a deep understanding of math and stats VS experience running logistic regressions in Python. (but we're cool with Python / Logit / experience)

_Engineering_: (1) full stack engineers with experience with React, GraphQL, and React Native to work on our web app for clients and our mobile app for tasters. (2) Data-Engineers with experiance in micro-batch processing for machine learning pipelines.

Next Steps: please contact Jason Cohen at JasonCEO@Gastrograph.com to apply.
