We're a team of seasoned operators and developers that loves to move fast and laughs in the face of nasty-hairy challenges that lie in our path.

NoRedInk | Director of Engineering, Site Reliability Engineers, Engineering Managers | 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 5 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.

For our Director of Engineering role, we're seeking an experienced engineering leader who’s operated and scaled a high-performing team, cares about tackling complex technical challenges, and maintains a high bar for talent and engineering practices.

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

PromptWorks | Software Engineer, Senior Software Engineer, UX Designer, Business Development Manager | Philadelphia PA | ONSITE https://promptworks.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 (at least very interested in learning) plus (ideally) 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!

Clio | Calgary, Vancouver, Dublin, Toronto | Full-Time | Onsite | https://www.youtube.com/watch?v=aXuvPxnVJWM Clio does legal practice management software.

SimplePay | Ruby on Rails Developers | Cape Town, South Africa | REMOTE

The story (skip this paragraph if you don't like stories in your job posts): I founded and continue to run this startup. Most of the team works from our office in South Africa. However, 4 months ago I moved to Singapore for work / personal reasons. I used to be quite averse to the idea of remote workers, but seeing as just about everyone will now be remote from my perspective, I decided it's a good time to start focusing on hiring for remote work. We’ve hired 3 remote developers so far and it’s been a great experience!

SimplePay is online payroll software for South Africa, Ireland, Singapore and Hong Kong. Our software lets thousands of small business owners (and their accountants) run their payrolls without headaches, so they can focus on the challenge of building their businesses.

Do you believe most SPAs are a pile of steaming crap, but wouldn't mind digging into Vue.js for pages that will benefit from the increased interactivity? Do you laugh when people give up the power of PostgreSQL in favour of data stores that don't offer any benefits for their use case? If so, you may fit in well with our mindset. The work will include: Doing direct integrations with banks that offer good APIs; Expanding our API for other systems to integrate with us; Adding new features; Optimising for performance; Integrating with government systems; Squashing bugs; Eventually, the opportunity to do some mobile development (probably using Flutter).

Experience: Due to our full pipeline, we can only hire developers who have a few years of Rails experience at this time, or polyglots who at least know Ruby. Previous experience with remote work would be a bonus - we need people who understand the challenges and can share what they've learnt.

Location: Most of the team is in GMT+2, and I'll be in GMT+8 going forward. So anything from GMT+0 to GMT+8 should be OK, unless you keep unusual working hours. We are a registered employer in South Africa and Singapore, so it would be hassle-free if you're based in those countries. If not, and if you've never done remote work for a foreign company before, please be sure to find out how to legally do this in your particular country (it may involve registering as self-employed, for example).

Please mail careers@simplepay.co.za and put "Hacker News" somewhere in the subject. I look forward to transforming the company to being more remote-friendly.

Most of our users are based in the US, and there may be occasional travel to attend conferences and visit schools using our software, which is a lot of fun! ( See the wrapup from our last conference in Chicago, IL: https://blog.kamihq.com/iste-2018-wrap-up/ )

Keen IO | San Antonio, TX | Solutions Architect | Full-time | ONSITE | https://keen.io

We acquired Keen last December and have been carefully growing the team and getting the product in shape since then. We started with ramping up engineering over the spring/summer and we just finished staffing up our CS org. We've got enough organic demand that a Solutions Architect is our next critical hire (our chief platform engineer and I have been splitting that work but its definitely a full time job at this point).

At Keen the Solutions Architect role is a bit different. Its a highly technical role and you work both pre-sales and on post sale implementation. Our analytics platform provides general purpose building blocks to solve a wide variety of challenges, we rely heavily on discovery and a deep level of analytics expertise to help our customers assemble exactly the solution they need.

What we’re looking for: - Experience in either a Sales or Customer facing engineering role. - Solid understanding of SQL or NoSQL concepts and implementations. - Technical background working with modern web technologies, stacks, and API’s.

You should have some familiarity with one or more of the following: Javascript, Ruby, Node, or Python, etc.

Ultimately, what we’re looking for is someone with familiarity implementing business or product performance analytics ( activation, engagement, retention, adoption), and that can help other companies use our platform to implement similar metrics and data models.
