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, 5 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 (maybe 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.

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.

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].

Transcriptic (YC W15) | Backend, Full-stack engineers, Designers | Menlo Park, CA | https://transcriptic.com | FULL TIME; ONSITE

Transcriptic is turning biology into an information science by creating a fully automated cloud wet lab. Biologists anywhere can submit and run experiments over the internet on-demand and without investing up-front in a lab facility.

The Transcriptic Common Lab Environment (TCLE) takes Autoprotocol (http://autoprotocol.org/), a high-level JSON description of a biological protocol, and executes it on our custom-built robotic workcells. The protocols we handle routinely involve solving constraint programming models with thousands of variables and constraints in order to find a plan that fulfills the scientist's biological intent.

Scientists manage their experiments through our web application or via our API. We provide a single platform that controls scientific devices from many vendors in a unified way, and an interface to control our automated labs.

Bonobos | Various Engineering Roles | Full-time + On-site in NYC | www.bonobos.com

Bonobos is looking for a few Senior Engineers (Frontend, Full Stack and Site Reliability) that have experience in Rails and ideally some Javascript experience as well. We work cross-functionally, so you’ll be on a team composed of other Engineers (frontend, full stack and iOS), a Product Manager and a UX Designer.

We value self-awareness, empathy, intellectual honesty, positive energy and judgment, often over experience. We hire based on these core virtues and foster a “best-idea-wins” environment where creativity and individuality are not only appreciated, but encouraged.

Apply here: Senior Frontend Engineer: https://boards.greenhouse.io/bonobos/jobs/1214524 Senior Full Stack Engineer: https://boards.greenhouse.io/bonobos/jobs/1178708 Site Reliability Engineer: https://boards.greenhouse.io/bonobos/jobs/1315808

TrueCar | Santa Monica, CA | ONSITE or REMOTE | Full-Time | https://truecar.com

TrueCar is hiring engineers to help us improve the car buying experience. We're on the verge of finishing up our replatforming initiative, and we're getting ready to re-accelerate our product development and further improve our infrastructure.

A good chunk of our engineering team, including leadership, came from CarWoo (YC S08). We value moving fast, structuring things so that we can keep moving fast, and not being afraid to do hard things. (This is sounds so obvious on HN, but it can be a hard sell sometimes when you're in the automotive industry.)

The core development frameworks we use are Rails and React. Our data stores include PostgreSQL, Redshift, Elasticsearch, and HBase. For infrastructure management, we use Terraform and Ansible. All of this runs on AWS.

Our core consumer- and dealer-facing application is a Rails application with a React frontend, backed by PostgreSQL and Redis. It's an intentionally monolithic Rails API. We also have other Rails apps for data curation, infrastructure management, and data movement to facilitate a lot of the workflows around data that add value and speed up our development.

We've also built internal tooling whenever it helps us move faster or drastically reduce the amount of manual work for our teammates. One of our tools, Spacepods, is a Rails app that churns out identical, isolated development environments (complete with data sets) so there's a mini-TrueCar that each engineer can start developing against immediately, without having to worry about breaking a shared integration environment that other developers depend on. Spacepods also powers our deployments and coordinates our CI/CD pipeline.

Openings:

- Senior Rails Engineer. You've run Rails at scale and know Ruby and Rails really, really well. "Convention over configuration" is always nice to get started, but you've had to roll up your sleeves and configure things, ranging from Ruby VM internals to caching layers to connection pooling. You'd be working on the Rails app that powers our consumer-facing experience.

- Senior Rails Engineer (Platform). You've run Rails at scale, maybe in a smaller company, and have thought to yourself at some point, "If only we had the resources to build developer tools to make our processes better and more repeatable." You'll probably have a lot of fun in this role if you like working on the tooling that gets used by other engineers and get a kick out of enabling others to be 10x/100x more productive.

- Site Reliability Engineer. You know Linux systems, networking, and/or AWS really well. Each team member has a slightly different emphasis but everyone on the team has in common is that we value reliability, observability, and performance.

- Site Reliability Engineer (Data). Measure, monitor, and understand YARN/HDFS/HBase performance in production. Design/architect deployment and verification procedures for data pipelines. One of the overarching and continuing challenges here is to take everything great that everyone loves about DevOps and CI/CD, and apply it to our data pipelines. Inherent statefulness and the size of the data make this a challenge.

- Data Warehouse Engineer. Write ETL to efficiently bring in data from various data sources, enrich it, and make it available to everyone in the company so our decisions are backed by good data. We make use of Postgres and Redshift.

Even if you're not sure you fit in any one of the above, please reach out if any of this sounds interesting to you. (If you read all the way down here, it's a good sign that we should talk!) At the end of the day, we're just looking for smart, determined, pragmatic people who love building things and solving problems. We care less about hitting all the bullet points in a job description.

Still interested, or just want to talk? Reach out to me at jgo AT truecar.com

Abl Schools | Multiple positions (engineering and design) | San Francisco |Full-time | ONSITE | www.ablschools.com

Technology has made the world more connected, fundamentally changing how we live, work and interact; yet traditional schools have not evolved to prepare students for the 21st century. Replacing textbooks with tablets won’t be enough. We believe schools need a new foundation. That’s why we’re building a web-based school scheduling platform, that allows administrators to put master schedules and daily calendars into a single cloud-based system. We are creating the next generation of software for all K12 schools to fundamentally change how they design, measure and improve their schools. We are also a company that deeply values diversity in every way.

View openings, including sales, engineering, customer success, and design on our site: https://ablschools.com/careers/

--------------------------------------------------

Personal note: I've been on the Abl engineering team for almost a year and I love it. The mission and the team make coming into work enjoyable. We have a diverse team, we're well funded, we have experienced leadership, and I could go on. The interview process is, in my opinion, very fair. You won't be asked to white board and we understand that the process is just as much as the candidate getting to know the company as it is the other way around.

If you have any questions, feel free to reach out to me - my contact info is in my profile.
