Kotlin Jobs - August 2021

Primer | Data, Dev Ops, API, Back End, Distributed System Engineers | REMOTE | https://www.sayprimer.com

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 these companies to accomplish this much faster without having to engineer an expensive system.

We've bootstrapped ourselves in 2020 to supporting a team of four and are quietly finding our way into the growth marketing playbooks of top B2B companies in Silicon Valley. We're experienced founders that have built successful companies and are looking to create a business aimed at solving hard problems for our customers, generating real, sustainable revenue, and providing a supporting environment for our team (most of the team has young kids and we support a flexible schedule).

Our stack is React/Node, but we're positioning ourselves to invest in scaling to meet the demands of our data-intensive, distributed workflows. We're looking for experienced, thought partners to help us architect a solution for the future (Elixir, Go, Clojure, Kotlin, Haskell, Rust). The roles we'd like to fill are:

* Dev Ops Engineer (AWS/Kubernetes)

* Data Engineer (ETL/API)

* Senior Back End Engineer

We can offer a very competitive salary and significant equity in addition to other benefits.

Interested? Feel free to contact me directly at juan [at] sayprimer.com

## About Us

Symmetry Investments is a post startup USD 7+ billion alternative asset management company with around 230 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, post-COVID.

I'm one of the three people running the firm, 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 four 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), [Andrei Alexandrescu](https://www.youtube.com/watch?v=es6U7WAlKpQ) 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++ and D at runtime; Python interop is in alpha; and C# is on the way. 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 CIO starts asking you questions about your work.
