## 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.

ConsenSys Software | Cloud Engineer / Ops / Backend Software | Fulltime | Remote, ideally UTC+9 timezone adjacent but not a deal-breaker

ConsenSys Software (formerly just known as ConsenSys) works on a range of open source and private/managed offerings and services. Ones you might have heard of are Infura, MetaMask, Besu, Teku (and more). A big solid entity in the cryptosphere, one which is a pleasure to work at with lots of internal opportunity and encouraged personal and professional growth.

I'm working on the team this hire will go to, so you'd be my future coworker (and the rest of the team's).

We're looking for people who have shipped and owned production code; ideally in C# but other languages are fine if you can learn/translate those skills.

Technologies include C#, TypeScript, shell (bash), Docker, Kubernetes, Azure.

We're currently using Azure but equivalent experience on other cloud platforms (e.g. AWS, GCP) is okay if you can translate that knowledge and of course we'd help getting you up to speed with anything required.

You'd be working on Quorum Blockchain Service which is an enterprise offering for GoQuorum managed consortiums on Microsoft Azure. Shipping and owning features in .NET Core, some ops work where required and more. Crypto knowledge isn't required but is definitely a bonus. Ideally we're seeking people on the senior side.

Flick me an email if you're keen and I'll see what I can do about referring you directly: jordan.coppard+hn@consensys.net

Fern Creek Software | Louisville KY | 100% Remote

Fern Creek is a software consulting company. We build stuff for other people, usually in .NET on Azure but we do other stuff occasionally. The company has been around since I started consulting independently about 20 years ago. Recently I started taking on larger projects that need more people and as a result, started hiring people. Sometimes a 1099, sometimes W2.

This is not super sexy stuff where you will get options that might be worth millions, but likely worth nothing. What you will get is a load of experience on new tech (asp.net core, azure, blazor etc) and a great focus on the best feature of all...shipping.

The job is remote so you don't have to be in Louisville though if you are close that is cool.

Set your own hours and all that, I want pros not people that need babysitting.

3 openings right now... -Full stack dev (C#, asp.net core, sql server etc)

-DevOps/Automation/QA dev (unit testing, selenium, azure devops)

-Mobile dev (Xamarin, React Native)

Live the stress free life, work from home, build some cool tech, make money, be happy etc etc.

Aviron Software | Senior Full-stack Engineer/Lead Software Engineer | Remote | Full time

Aviron Software is a boutique consultancy specializing in React/web/mobile/.NET/cloud development. We're one year old today and have gone from one to four people in that time - and we're still growing.

We don't advertise (we'll probably start soon) - because so far our customers have all found us. We don't even have a website (we definitely will soon). And - we have a 100% customer retention rate for a reason.

Seeking good senior-level folks with lots of web dev experience, especially using a frontend framework like React. Good/great JavaScript skills are key. We also do a lot of .NET, so some exposure to C#/.NET is desirable, but not required if you know a good backend already and are willing to learn. Experience building in/on a popular cloud system (Azure/AWS) highly desired as well.

We offer full benefits and competitive salaries commiserate with experience, along with a 40 hour workweek and flexibility for when you can work. As long as clients are happy, we're happy. One of my engineers sleeps until almost noon everyday.
