SimplePay | Ruby on Rails Developers | UTC+0 to UTC+8 | REMOTE

SimplePay is a profitable, developer-owned online payroll software company, with solid annual growth. Our software lets 23,000 small business owners (and their accountants) run their South African, Ireland, Singapore and Hong Kong payrolls without headaches, so they can focus on the challenge of building their businesses. We're also developing new product lines.

Our development team was already mostly remote pre-pandemic. We have a very supportive culture, and are putting a lot of thought into ensuring remote work is happy work.

To find out more about us, check our developer blog (https://tech.simplepay.cloud) or about page (https://www.simplepay.co.za/about)

Do you believe SPAs are overkill for most apps, 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 SQL DBs 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.

Experience: Ruby on Rails. If you've used other web frameworks and are keen to get into Rails we'd definitely consider you! Just be sure to mention that in your application. The work is mostly on the back-end, but some front-end skills are welcome - we're doing more and more interactive things with Vue.js.

Location: UTC+0 to UTC+8

Please apply at https://teamsimplepay.applytojob.com/apply/52BYVkQodf/Senior... and attach your resume / CV in PDF format. In the "Cover Letter" section of the application, please include 1) the time zone in which you reside, and 2) a link to a PR created or an issue logged for an open source project (no matter how small or long ago) as the first two lines. Also tell us why you would like to join SimplePay.

https://fishtail.ai | REMOTE | Full-time | Data people (science/eng/devops) + backend/frontend/full stack

We are a super un-sexy, VC-backed, revenue-generating, Trade Finance automation company (think Pipe for the real world) that's bringing the the $10tn Trade Finance space in to the 21st century.

The problem we're solving

When Walmart gives La Croix a $100k order for seltzer, not only does Walmart not pay after receiving goods for 3-4 months but La Croix has to cover the cost of actually making their goods for a bunch of time (months). As a small business, this sucks hard. Fishtail will lend to La Croix when they get an order from Walmart so they can satisfy demand without tying up huge amounts of working capital. Usually banks will lend to folks only when the product makes it to Walmart (and only to large companies, who don't traditionally need $) -- the net effect of Fishtail is that we lend earlier in the chain to smaller businesses (which is a super duper hard problem).

Tech stack

Our web stack is Ruby on Rails + turbo/stimulus/tailwind - data stack is python/pytorch + spark. We get a boatload of data tracking every vessel in the water/every plane in the sky (among other datasets like every trade transaction that has happened over the past N years).

Fun fact

We have a sustainability-linked trade finance product where we can tie the interest rate of our loans to the sustainability of the individual shipment (i.e. the greener the shipment, the better your interest rate) -- this is super nifty when you consider that transportation is responsible for ~30% of the world's green house gas emissions and there's really no good way to identify the best option to get from A to B.

What we need

We're looking for support taking our product to the next level on all fronts (engineering, data, sales, marketing, operations, etc) but are mostly looking for more data people and web people to help us build out our credit/performance risk models + customer-facing product.

Reach out to hiring@fishtail.ai if you want to help small businesses win while saving the planet with us.

Apply4 | Senior Ruby on Rails Engineer | Remote (EU timezone) | Full-time | $70k - $85k | https://bit.ly/ycror

Our software helps local governments manage public outdoor spaces (parks, roads, etc.) more effectively, making it easier for good things to take place, like special events, filming and infrastructure improvements.

We’re used by cities and local governments in multiple countries and our customers love us (Net Promoter Score of 71!) We’re looking for a seasoned engineer to join our friendly and supportive team to help us continue to improve on what we have, making sure our platform can serve people well in the years to come.

We’re a small (but established) company so you won’t be a cog in a big machine here — you’ll be working directly with me (the CTO), our product manager and our other two developers to shape the platform, helping to decide what will be the most high-impact thing to work on.

Feel free to apply using the link above or reach out to me directly.
