Academia.edu | Full Stack Engineers; Product Managers; Data Scientists | 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, product managers, and data scientists. 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 the CEO, Richard Price, at richard [at] academia.edu

Hey HN! I'm Jesse, the head of engineering at Strive Talent. My email is jesse@strivetalent.com.

Strive Talent is a seed-stage, mission-driven startup dedicated to giving everyone a fair shot at a great career. Right now we help companies around the US staff sales and customer support jobs with candidates that would typically be overlooked. A typical hiring manager spends ~6 seconds per resume to evaluate whether a candidate should be given an interview. Instead, we administer a combination of cognitive tests, work-sample tests, and phone screenings, which allow us to evaluate a candidate according to the traits that actually determine their ability to do the job.

Our team is small, but we're well-funded: https://techcrunch.com/2018/01/24/stressing-aptitude-over-ac....

If you're interested, please send a resume and a paragraph explaining what it is about Strive that resonates with you to: jesse@strivetalent.com

Strive is a great place to join if any of the following are true:

• You care about connecting people with dignified livelihoods.

• You care about people getting jobs based on their ability to do the work, and not their pedigree.

• You want to come in to work each day and be able to ask, "How many people got a better job yesterday because of us?"

• You want to join an early-stage startup where there are still a lot of open product and technical questions.

Our core platform is built using Rails, React, PostreSQL, and other standard moving parts. Experience is those technologies isn't required, but evidence of skill and adaptability are.

Flatiron School (now part of WeWork) | Software Engineers, esp. Seniors | New York, NY (NYC) | ONSITE | FULL-TIME

Hi, I'm the Engineering Director on the Product/Engineering team at the Flatiron School. I joined the team about four months ago as part of a general scaling up of the team (we're currently about 25 devs and growing) and love it. We mostly work on Learn, a modern Learning Management System that runs the school's online coding bootcamps. This place is an unusually kind and nurturing place, and we have a mission that we believe in. A number of the developers originally went through the Flatiron School, so the level of knowledge and empathy with users is unusually high.

We're looking for developers with a wide range of backgrounds, especially people with a few years under their belts and an interest in mentoring less-experienced developers. We value diversity of all kinds and would love to benefit from having many perspectives. I can speak from my own experience as a parent that it's a family-friendly place with pretty good core hours, flexibility around timing, good health benefits, friendliness toward dialing in (though we generally prefer to work together in-person) and just a generally nice vibe.

As far as the tech stack goes, we mostly use Ruby/Rails, Elixir/Phoenix and Javascript/React and we're moving to AWS. I wouldn't get too hung up on having all of these particular items on your resume. What's most important to me is having some ways of solving problems collaboratively on a team. There's all kinds of cool problems to work on here as we scale our user base, course offerings, team and our infrastructure, and there will be plenty of new problems that will require adaptability, openness and an ability to communicate.

We have some job listings at https://flatironschool.com/careers/, but if you're interested in finding out more, applying or just want to chat, please drop me a line at paul@flatironschool.com.

Blackbird Studios | Lead Fullstack Developer | San Francisco | Onsite or Remote* | Contract to hire

Blackbird Studios is a full service digital product studio. We specialize in a holistic approach inspired by HCD and Lean. Services include CTO consulting, product strategy, engagement strategy, UX/UI, and development plus long term BML iterations and maintenance. We work with large and small companies/startups on projects ranging from 1-6 months with 2-6 people on each project.

We build full stack web, mobile, physical installations, etc. Our favorite stack is React/Redux, GraphQL, Rails, and React Native. We also use a wide range of other tech as needed since we face a pretty diverse set of challenges. Recent and upcoming examples: Elixir/Phoenix, .Net, C++/Qt, embedded Linux, Native iOS/Swift, Native Android/Kotlin.

Working at Blackbird is very different from larger product companies. We operate in very strategic relationships with our clients which gives us a unique opportunity every few months to deep dive into a new interesting understanding of our client's business and build ground up new apps where everyone is making major and early contributions.

We are looking for a Lead Developer with extensive experience in dev team leadership, new product development, and collaboration with business and design stakeholders. Serious consulting experience is also a huge plus. Specific skills ideally include our favorite stack (see above) plus deep knowledge of either native iOS or Android. As a senior Blackbird team member, occasional travel to San Francisco and other locations is part of the job for project kickoffs and other critical collaboration phases or meetings. In a given month this can be anywhere from no travel up to a couple days every week or occasionally an entire week on site with a client.

I am a founder so ask me anything! If there are other aspects of what we do that interest you definitely still hit me up!
