Feature Labs builds automation technology for developing predictive models. With our tools, users can discover the most predictive patterns in behavioral and transactional datasets to accelerate the data science process.

We’re growing our technical team with engineers interested in pushing the boundaries of data science automation. In this role, you have the opportunity to define and implement big data systems while collaborating with our top notch engineering team and grow into a leadership position within our team.

Currently, our stack is mostly Python on the backend (pandas, django, sklearn), React for the front end, and AWS and docker for deployment. Above all, we prioritize the ability to choose the right approach to solve a problem. Our first product, Featuretools, is available as an open source python library here: https://featuretools.com.

Petuum is building a platform for easily running distributed machine learning. The company was spun out of a Carnegie Mellon research group about two years ago, and we have recently raised a $93 million series B round (bringing our total funding to $108 million) to support our rapid growth.

The Petuum development platform and gallery of AI building blocks work with any programming language and any type of data, allowing managers and analysts to quickly build AI applications without any coding, while engineers and coders can further re-program applications as needed.

What we look for:

* Front-end: Experience with Typescript and Angular is a plus.

* Back-end: Experience with some of C/C++, Go, Python, CUDA, and Kubernetes is a plus

* Data science: We look for at least a master’s in data science or related. Industry experience with TensorFlow/Caffe is a plus.

Qtum is a smart contract platform built on a blockchain model similar to Bitcoin. We aim to drive the entire smart contract space forward with this project. Qtum is still young, and has been around for around 1.5 years. We use a fully remote workflow but typically try to all meetup in Shanghai once a year or so. We have team members based around the world, including China, USA, Canada, Sweden, Morocco, Colombia, and many others.

We are currently looking to expand our engineering team by 1 or 2 well experienced people. First of all, no blockchain experience is necessary (though it is always helpful). Qtum is aiming to implement an x86 virtual machine on which smart contracts can be executed. So, we need people to help us build the virtual machine, and test it to make sure it is correct (since fixing mistakes is very hard). We are also looking not just for engineers to build the virtual machine, but also to craft an operating system-like environment in which smart contracts can run. So, this may provide common necessities like memory allocation, string manipulation, etc... along with porting languages like C++, Rust, and Go to be easily used within the smart contract environment.

So, in summary we are looking for someone that loves working at the low level, bare metal level. If you have operating system development experience, that's a plus. If you live and breathe assembler, we'd like to speak with you. No matter if your preferred architecture is x86, ARM, or whatever. Even if you made a cool Z80 assembly program for your TI-84. It's all good stuff. We will be implementing most of the core logic in C++, but Rust and Go experience is a plus, especially with low level experience porting or dealing with the low-level details of the compilers and operating environment.

We take testing and code reviews seriously, being a blockchain project where mistakes can cost millions or more. We use a pull-request model, where each PR must be approved, and we have an always growing set of automated tests. Attention to detail and experience with working on security critical software is a plus. We'd prefer highly experienced senior people at this point, but we are accepting of anyone with experience in bare metal or assembly development. (Yes, we include open source hobby projects as experience)

I'm the Lead Developer and one of three Co-founders of Qtum, Jordan Earls. Email me with your resume or CV at earlz@qtum.org, and make sure to include a brief description of why this sounds interesting to you, and what makes you qualified for it.

PS: Unlike the common misconception, we do not require that you accept Bitcoin for your salary despite being a blockchain project.

Matterport makes a 3D camera and web platform that allows users to easily capture and display 3D models of physical spaces. Check out some example spaces in our gallery: https://matterport.com/gallery The Backend Engineering Team works on our Platform and APIs. The stack is Django/Python/Postgres on AWS, and Fastly as a CDN. We're a small team right now, at 4 engineers who mostly do Django and 3 who mostly do infrastructure and developer tools.

We're hiring more in this area because we're starting to get some very interesting scaling challenges:

* We host over 700,000 highly detailed 3D models of real places captured by our cameras, amounting to over 600TB of data.

* We serve over 20 million 3D views every month, which amounts to over 10 billion requests and 400TB of data.

Our APIs are used by all parts of the company: 3D data gets uploaded from our cameras, processed by our vision pipeline in C++, Python, and TensorFlow, and consumed by our Javascript/WebGL and VR applications. The Backend team makes new additions to the API constantly, and works to ensure the APIs are secure, scale well, and are well tested.
