FunnelCloud | Toronto | Software Engineers | ONSITE | Full Time

We use a blend of Elixir/OTP, Scala/Akka, Ruby/Rails (API, migrations), and Ember, alongside Kafka, Postgres, and Redis to build a Manufacturing Execution System which listens to signals from machines used in manufacturing, and writes back to them to track parts and control manufacturing processes. There are many interesting features to tackle, and a good start on the v2 architecture with many small elixir apps interacting through kafka (via command and event topics). Scala is used for individual part tracking on a model of the physical process route.

The domain is physical, and is a great fit for event driven systems and domain driven design. We talk about things in terms of aggregates, commands and events more or less daily. The code is well covered. It is a small company so we have a few opportunities in terms of process maturity but generally the technical approaches are reasonable.

The company is young but bootstrapped and profitable and growing with substantial equity available for really strong hires. We have some very smart people kicking around as is common in my experience in startups that end up turning out pretty well. I was working at Google for a bit - I'm trying to bring examples from my experiences there into the culture here as we grow.

I worked here on contract and flipped to full time on seeing the equity package, problem space, and rate of growth. It's a good opportunity with smart people in an interesting technical space.

I'm currently hoping to fill a spot for one of those ember/ruby/elixir people (any 2 would be good). I come from a more functional background with scala but I think with the current technology having 2 of 3 of ember/ruby/elixir would be good.

Strong Scala or FP candidates would also be welcome to come if they're alright trying on dynamic typing in elixir as there is a lot of work to be done squarely in elixir and scala right now. You'd be able to pick up rails easily enough for what it's used for.

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, a month ago I moved 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.

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. 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 iin 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.

Strive Talent | Full-stack Engineer + Front-end product engineer | FULL-TIME ONSITE | San Francisco, CA | https://www.strivetalent.com/

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.

SolarWinds Cloud | Full-stack developers | San Francisco, CA / Boston, MA / Vancouver, BC | Onsite | Full-time

AppOptics (https://www.appoptics.com/) is a monitoring platform that gives our customers (software engineers like us) deep understanding of how their applications are performing.

As a monitoring product we collect a lot of data, but that's only half the battle: one of the biggest challenges we face is turning that data into a product that helps engineers and is satisfying to use. We're looking for a full stack web application developer to help us grow and refine AppOptics. If you're interested in data visualization, monitoring, or distributed systems then this could be the job for you.

Our stack consists of ES6, React, and Redux talking via REST and GraphQL to Rails and Sinatra apps. We develop locally in Docker containers and deploy to AWS.

The AppOptics team is small (~30, growing) and tightly knit. We ship early and often so that we can iterate on user feedback, we're always evaluating new technologies to see if they will benefit us, and we have lots of opportunities for individuals to have a big impact.

I consider myself lucky to work with this talented, thoughtful, and fun team. People are what make a job exceptional. Email dkuebrich@solarwinds.cloud if you have any questions or would like to join us!
