SimplePay | Kotlin / Java Web Developers | UTC+0 to UTC+8 | REMOTE

SimplePay is a profitable, developer-owned online payroll software company, with solid growth. Our software lets 23,000 (and counting!) 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 - for example, we're doing a new time tracking and staff scheduling system.

We've decided to add Kotlin to our stack for server-side development. Experienced Java developers who want to get into Kotlin are also welcome to apply. As much as I enjoy Ruby on Rails (and it's definitely helped us succeed), refactoring is becoming more painful the larger our code base becomes (using Sorbet helps, but can only take us so far). We intend to use Kotlin for the new products we're launching as well as to rewrite selected components of our existing system where it makes sense. I haven't coded in a statically typed language in years, but I've been writing Kotlin lately, and it feels surprisingly productive.

We haven't decided on a web framework yet. I don't mind Spring Boot, but investigating lighter weight alternatives would be great too (you can tell I have many battle scars from dealing with framework upgrades). We use PostgreSQL as our DB server. On the front-end, we mainly render plain HTML, but use Vue.js on the pages that need more interactivity - this role is more focused on the back-end, but front-end skills are welcome too. As you can see from our no-nonsense stack, we prefer to keep things simple with robust, proven technologies, so we can focus on solving client issues.

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

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

Location: UTC+0 to UTC+8

Please apply at https://teamsimplepay.applytojob.com/apply/WyQYFOo1wB/Experi... 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.

Primer | Engineering Manager, Senior/Staff Engineers, Product Design Lead | REMOTE | https://www.sayprimer.com

I'm an experienced Y-Combinator founder and engineering leader. My teams have built everything from machine learning systems that crunch 200+ billion data points / day at Wheelhouse to groundbreaking 3D/CV technology at Modsy that resulted in a patent.

We're building the "CircleCI of Growth Marketing" at Primer. Growth marketing has boomed in recent years and every B2B company needs a tailored, data-driven approach to their market in order to win business. Primer is enabling our customers to accomplish this much faster without having to engineer an expensive system.

Here are a few reasons to work with us:

* We bootstrapped the company to $700k in revenue with a team of 4 and recently raised a round to support our consistent 20.1% MoM growth in 2021.

* We have a track record of helping our team members catapult their careers to the next level.

* Our team is fully distributed, supports flexible schedules, genuinely values work/life balance, and we spend 95% of our time outside of meetings.

* 50% of our product/engineering team is women.

* Our engineering ceremonies and technology are world-class, put engineers in the drivers' seat, and emphasize transparency.

* Our culture is high-achieving, trusting, genuinely kind, and collaborative.

Our stack is React/Node, but we welcome polyglots. In general, we're looking for thought partners to help us architect a solution for the future so experience with other languages (e.g. Elixir, Go, Clojure, Kotlin, Haskell, Rust) is a plus. 7+ years experience minimum.

## Roles we are hiring for

- Business Analysts: business analysis, documentation, team and tool design

## About Us

Symmetry Investments is a post startup USD 9+ billion alternative asset management company with around 250 people across multiple time zones and locations.

Our core technology team has been remote-first for some time, and the whole company is following suit, accelerated by the pandemic.

I'm co-CEO and co-COO, responsible amongst other things for technology across the firm and I’m posting this myself. That should give you an idea both about how seriously we take technology and the culture of the firm.

We are five years into a period of transformation from what was initially a fairly standard enterprise finance technology approach to something new that recognises the importance of both the humane and the technical for discretionary portfolio management and for the business of running an alternative investment manager. [Amaury Sechet](https://www.youtube.com/watch?v=AhR4PSExnqk) and [Atila Neves](https://dlang.org/blog/2019/10/15/my-vision-of-ds-future/) have been working with us as long-term consultants and we have many other talented people with lower public profiles.

It's not easy to integrate practitioners who may spend most of their day programming, but are oriented towards solving business problems, with developers who are specialists in programming. To achieve this, we wrote a little functional DSL that's now in production. Type inference of returns and parameters using inequality constraints is in a feature branch and there is plenty more to do on the language itself as well as the ecosystem around it. SIL can compile and call C++, D, and C# at runtime and interoperate with Python and R. What might be a project in itself elsewhere can be just a set of functions in Symmetry Integration Language.

The language is written in D and we have a close involvement with the D Foundation and community, hosting DConf in London. So we are looking for outstanding native code developers who would like to write D as well as people to work with practitioners writing Symmetry Integration Language. Also looking for people to write documentation and work on the build.

It's quite a creative place where we encourage a degree of courage amidst practical constraints, and we are open to doing things a different way if it's commercially sound and in the interests of our investors.

We look for virtues and capabilities over only experience and credentials although those things aren't a disadvantage. Do not let a lack of credentials or qualifications prevent you from applying. We've recently hired experts with C++, Common Lisp, D, Haxe, Haskell, Julia and Perl backgrounds, and are happy to bring them up to speed with the tools we use.

Compensation is currently not quite at Netflix standards but is generous to very generous over time by broad technology industry standards. We recognise and reward technical accomplishment and have a very flat structure - don't be surprised if our founder and Chief Investment Officer starts asking you questions about your work.

Substack | San Francisco, CA; New York, NY, and remote in the US and Canada

Help build a better future for writing. We believe that what you read matters and writing is valuable. We’re here to help writers go independent and thrive, and we’re hiring.

We're hiring software engineers for web (JavaScript + TypeScript, Node, React), iOS (Objective-C, Swift), and Android (Kotlin), and data analysts, security & systems engineers, designers, and product managers.

Here's how we think about engineering:

- We bias to action. We work fast, make bold bets, and then course-correct as needed.

- We believe great things are built by small groups of exceptional people. We assemble tight-knit teams and give them clear, ambitious goals and the autonomy they need to succeed.

- Remote Collaboration and Community. The team has a home base in San Francisco, but there’s also an office in New York and some people are remote. We get together a few times a year to build relationships and work and celebrate together. Engineers are autonomous and independent and balance that with highly collaborative pairing sessions, problem solving, and more. It’s a team that celebrates one another.

- Empathy for writers. We do Empathy Hour, Office Hours, shadowing customer support, and find ways to get writers and engineers talking with one another. Substack started by building a product for a specific writer (Bill Bishop writing Sinocism) and we’ve strived to maintain that ethos as we’ve scaled – focused directly on the needs of people.

- Feelings Friday. We’re here to support each other through the ups and downs of a high growth startup.

- Diversity of perspectives. We are engineers with a diverse set of professional and personal backgrounds, and as a result have a working environment that demonstrates a wide variety of skills and knowledge.

- We like to have fun. We have a quarterly hackathon where engineers collaborate to build things they want to see on the platform. Many of the things people build get shipped. (~50% of things from our last hackathon have shipped or will soon)
