ThoughtWorks is hiring talented Senior Developers across the United States!

What we're looking for: * Ability to write high-quality, well-tested code. We don’t limit ourselves to one language; experience in any of Java, Scala, C#, Javascript, Ruby or Python is preferred * Experience working with Agile, Lean and/or Continuous Delivery approaches such as Continuous Integration, TDD, Infrastructure as Code, etc. * Knowledge and appreciation of cloud technology such as AWS, Docker or Kubernetes is a plus * A passion for automation; you don’t like doing the same thing twice * We value diversity; we support traditional and nontraditional career paths.

Green Bits | Full Time | SWE & SRE | Portland & San Jose

Green Bits is hiring for a ton of product and site reliability engineers right now (~10) to basically double our eng headcount. We're moving into a new 6,000 Sq ft office in downtown San Jose, and we're expanding our brand new Portland office to another floor after moving in in on January 1.

Green Bits provides inventory management, point of sale, and compliance solutions to over 1,000 retail cannabis dispensaries in both medical and recreational markets.

We've basically built an iOS App(switching to Android soon here) that's composed of a lot of single use apps in a dispensaries workflow. We also have a web application that can handle back office reporting and business analytics on a management level.

Core services are built in Rails, and the front end is a combination of EmberJS and Objective-C moving to React and React Native. Everything's on AWS (RDS, EC2, S3) and we use Docker and Kubernetes for orchestration.

The cannabis industry is growing rapidly (heh), and we're positioned to take a lot of the market in the very near future, so it's an exciting time to come on board.

If this sounds interesting, apply here: https://boards.greenhouse.io/greenbits#.WsKGadPwamk

RaiseMe | Full Stack Engineer | San Francisco, CA | ONSITE, Full-time

RaiseMe is expanding access to higher education by reinventing how students earn scholarship dollars from colleges. Our platform allows colleges and universities to award incremental "micro-scholarships" to high school (and soon, community college) students, based on academic, testing, extracurricular, and real-world experience. We've over 250 college partners, and users in 1 of 2 high schools in the US. Many of our students earn tens-of-thousands of dollars for college. The coolest part of our platform is how it educates students about the possibility of college in the first place. Many of our users are first-generation college attendees, or minority or low-income students.

Here's a recent VICE Impact article about us: https://impact.vice.com/en_us/article/ne3yvm/students-earned...

If you're an engineer looking to work with other smart and passionate individuals on the mission of helping all high school students achieve their college ambitions, get in touch! We are a small company, with a 14-person engineering team. We offer competitive pay, great benefits (including a dog-friendly office!), and meaningful equity stake.

Tech stack: Ruby/Rails, React/Redux frontend, MongoDB/Postgres/Redshift, with some small things in Go, Python, and Node.

I'm happy to answer any questions - email me at ben@raise.me. Our jobs listing page is here: https://www.raise.me/jobs

Academia.edu | Full Stack Engineer | San Francisco, CA | Onsite

Academia.edu is addressing two problems:

- Open access. The goal here is to put every academic pdf ever written on the internet, available for free.

- Robustness. The goal here is to produce a set of signals around any given academic paper that indicate how robust the paper’s claims and findings are.

It has emerged over the last few years that 65-90% of the academic literature is not reproducible. What this means is that if you try to reproduce the experiments described in a paper, 65-90% of the time you will not get the same findings. This is known as "the reproducibility crisis”. Peer review is not a robustness filter; we need a separate filter to indicate robustness.

With regard to open access, Academia allows academics to upload papers to Academia, and make them freely available. Academics have uploaded about 19 million pdfs to Academia.edu. About 30 million people come to Academia each month to access and share papers.

With regard to robustness, we think the way to build a robustness layer on top of papers is a) to mine the existing graph of citations for commentary and (b) crowd-source commentary/peer review from the academic community.

Academia has built a recommendation system which is the basis of our approach to (b), and a citation graph infrastructure that is the basis of our approach to (a). We believe that addressing robustness is a challenge and an opportunity. We need mission-driven engineers to come and help us.

We have raised $33 million from Tencent, Khosla Ventures, Spark Capital, and True Ventures. The company is profitable off a premium subscription model. Bijan Sabet from Spark Capital writes "We believe open science is really important. We believe Academia.edu is going to have a profound impact on the world."

We are looking to hire full stack software engineers. Technologies we use include Ruby, Rails, Postgres, DynamoDB, React. Our office is in downtown San Francisco. For more information, visit http://academia.edu/hiring.

If you are interested to learn more, please email Yuri Niyazov at yuri [at] academia.edu

NoRedInk | Back-End, Front-End, Full-Stack, SRE, or Engineering Manager | San Francisco, CA | REMOTE Pacific Time (PST) to Central European Time (CET)

We’re an ed-tech company on a mission to help all students become strong writers! Our team may be small, but NoRedInk is used by 1 in 2 school districts in the US, and students have answered over 2 billion questions on our platform.

We’re a group of friendly people who listen to and learn from each other. We discuss past mistakes openly so we can adapt our processes to the challenges that come with progress. Puns flow freely across our San Francisco office as well as on Slack, and we have remote engineers spanning six different time zones.

Our engineering team [1] prides itself on code quality and innovation. We use the cutting-edge Elm programming language for all our new front-end code, and have been migrating legacy React code to Elm as well. Our back-end is primarily Ruby on Rails, although we are working to split off smaller services as we scale to keep up with our traffic. You can read about our experiences with these technologies on our team blog! [2]

In addition to spending work hours open-sourcing useful libraries we develop [3], we also invest financially in open source. We hired the creator of Elm, Evan Czaplicki, to develop Elm full time. [4] Evan discusses his plans for the language with the team every week, periodically pairs with other engineers on Elm, and cracks up members of the sales team with his lunchtime jokes.

We use Amazon AWS for our infrastructure and automate all of our deployments using Chef and OpsWorks. We write a lot of tests, and use Jenkins for continuous integration. Our process for new features begins with our product team and in-house visual designer, continues with a GitHub pull request from a feature branch into master, and ends with our in-house QA specialist trying to break it before it reaches production.

We’re looking for engineers who want to work on a mission that makes a difference and who are the type of collaborators that value kindness and open-mindedness, over convincing the group they’re right.

You can learn more about what to expect through blog posts about our interview process [5] and on-boarding experience [6].

AdQuick | Venice, CA | Full Time | ONSITE | $80-140k

We've raised $3M+, ex-Instacart/Amazon, building a marketplace to buy and measure outdoor advertising. We were profitable last year are projected to explode in growth 2018. Looking for talented senior engineers to help keep up with demand. Email me if you're interested: fahim@adquick.com

About AdQuick

* Founded by ex-Instacart engineers/marketing * Raised $3M led by Initialized Capital (Garry Tan & Alexis Ohanian, Reddit co-founder). * Our customers include great brands such as: Kevin Hart, Peloton, FanDuel, Drake, Lyft & more.

Technical Stack

* Our tech stack is Rails 4, Webpack, React, Postgres, Heroku. * Looking for 3+ years experience in running production systems, ability to iterate quickly and sense of ownership. * Strong focus on user experience and putting the customer first.

Technical Challenges

* We have a complex frontend user interface. Users should be able to view 100,000+ markers and transit lines on a map without their browser crawling to a halt. We need to support complex and interesting map visualizations – layering political voting data, Census data, Foursquare data and more.

* We're a search company. AdQuick conducts a search every time the user pans the map. Searching by geography, demographics, AdQuick score and a myriad of other attributes from disparate data sources is computationally expensive. It will be a challenge to scale while keeping search response times and server costs low.

* We're a data science company. We integrate with Google Analytics & AdWords and other data sources to measure impact of physical advertising on online behavior (CTR in a region). ROI data from prior campaigns can help create more effective future campaigns. As our data warehouse grows, crunching this data will be increasingly challenging and more powerful. We'll use machine learning to create better campaigns overtime.

* Our backend systems have to deal with a myriad of inventory CSV, PDF formats, requiring robust and fast file validations, normalization and ingestion systems.

* We scraped Instagram and used image recognition to see if people shared photos of billboards. Turns out, a lot of people Instagram'd Drake's board. Innovative ROI tools are a core part of our offering.

Our customers tell us that they love and couldn't live without Dooly, including some well-known valley brands that we're excited to have using. New deals are coming in on an almost weekly basis.
