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

We’re on a mission to create the best place for engineers to figure out how to piece together their tech stack. Our vision is to transform the way that all SaaS tools and infrastructure are bought and sold. Open roles:

- Front-End Engineer (React + Rails) - https://angel.co/stackshare/jobs/186787-front-end-react-soft....

- Back-End Engineer - https://angel.co/stackshare/jobs/186795-software-engineer-ba....

- Developer Evangelist - https://angel.co/stackshare/jobs/86973-developer-evangelist

We're a hybrid-remote team of 10 that recently closed our Series A and we're growing very quickly, especially here in SF. Our Stack: Ruby/Rails/React/Redux/PostgreSQL https://stackshare.io/stackshare. https://techcrunch.com/2018/01/09/developer-social-network-s....

How we work:

Every engineer owns and is responsible for the products they build (e.g. Stack News). Before writing any code, the engineer tagged to the product writes a blog post announcing it to the StackShare community. From there, they spec out the product in detail and get feedback from at least one other engineer. Once the initial version of the product is built they ship it to a small group of beta testers, gather feedback, and iterate. Once the product has shipped to production, this engineer is then responsible for monitoring the metrics that matter for this product and iterating to improve it. Since we're building a product for engineers, we believe in letting our engineers work on things that interest them and giving them ownership over these products.

Interview process:

Phone Screen -> Technical Homework -> Technical Interviews -> Product Interviews -> Offer!

We provide a health management platform for healthcare providers and health insurers. Our company is relatively young, and this position would get you in on the ground floor, positioning you to have real impact on our engineering decisions and company culture.

Our stack:

ruby, rails, javascript, typescript, react, mongo, postgres, thrift

What we are looking for:

Do you not only want to see a problem done, but see it done cleanly in a way that makes you proud? Do you appreciate elegance, but despise implicitness and magic? Is code and system design something you like to really think about before tackling a problem? Do you like to discuss architecture with other engineers who care deeply about the quality of their code? Do you wish you were writing in a statically typed functional programming language a la Haskell, but are also satisfied applying those same concepts to more wild west contexts like Ruby and JS? If this resonates with you, please get in touch!

Listing Mirror | Lead Developer | South Bend, IN | ONSITE https://www.listingmirror.com

Listing Mirror is a two year old e-commerce startup that helps our customers to “Sell More, Work Less”. We are a small team from northern Indiana proving there is more than corn in Indiana!

Our customers each run online stores across multiple channels (Amazon, eBay, Walmart, Shopify, & more). Our platform manages Listings, Inventory, and Orders from a single hub - saving our users massive amount of time and replacing antiquated and cumbersome single use tools with our amazing and ever improving Listing Mirror platform.

We are always seeking to move fast and innovate. We all contribute to the direction of the product and the company, and we all make a huge difference in the success of Listing Mirror!

We are looking for a lead developer and first technical hire after the technical co-founder. You would work together with the technical co-founder (me) to continue developing the core web platform. You would help set the policies for development, and assist in both selecting and mentoring future technical hires.

This position requires innovation! You must be able to come see a problem, discuss it with the team or the customer- design a solution - and implement it! You are not going to be given a ticket from Jira to code, although there is a backlog to mine for ideas. You are not going to have a project manager give you the direction of the project and ask for daily updates - you need to talk with the team and drive the project forward. You are not going to just code a rough draft and pass it off to QA to test - you will write your own automated tests and deploy it to production. We do not have a six month development cycle, we practice continuous delivery and deploy to production many times a day without our customers being disturbed.

We run on a Django + Kubernetes platform, but it is not required that you have experience with either. However you SHOULD have experience with web technologies (HTML/CSS/JS) and at least one modern web framework (Django / Rails / SpringMVC / anything along that route), and modern practices like writing tests and using git.

Please send resumes to careers@listingmirror.com for consideration or just to chat more!

We're growing quickly, with 80MM registered members, and are mostly self-funded to 100+ employees, so we're highly focused on data-driven decisions and making smart capacity investments for the future. We're one of Boston Business Journal's Best Places to Work (again!).

Recruiting for multiple roles, especially:

Platform engineer (including technical lead) - Build all our core systems (including interesting architecture/scaling problems), working on a well-documented code base in a team with a strong review culture and very clear communications. We use a Java/Hibernate stack; happy to get applications from people with experience in comparable technologies.

Front-end engineer - Build all our member-facing applications including Jobcase.com, working mostly in Ruby on Rails. Drive the member experience for acquisition and social network features, working closely with product management and design/UX.

Quantitative data analyst - Own a slice of our business metrics and drive member acquisition and engagement. Send email/SMS communications, work with engineering to build new flows and features, and come up with experiments to optimize the member experience.

Data science / machine learning / information retrieval (experienced) - Help our members find relevant advice and jobs, and our colleagues make good decisions. Have a direct impact on revenue and on engagement, working with a team that's making major optimizations for our members and with colleagues who are uniformly data-savvy.

Interview process is a phone screen, then onsite interviews, with onsite design exercise and/or take-home coding/analysis exercise. Happy to answer questions, jberk at jobcase.com - my team works pretty closely with all of those teams.

SevenFifty Technologies | Full-stack Developer (Rails); Customer Integration Engineer | New York, NY | Onsite

SevenFifty is modernizing the wholesale beverage alcohol industry, which is massive but technologically antiquated.

You'll be joining a small engineering team tackling a wide array of challenges - from complex data processing to modern, interactive web frontends; from liberating data from decades old mainframes, to consuming and writing APIs used by everyone from small retail shops to large conglomerates. We want people who are excited about learning new technologies and passionate about transforming a broken industry.

Technologies: Ruby, Rails, JavaScript, Backbone, React, small bit of Clojure
