## About Us

Symmetry Investments is a post startup USD 7 billion + alternative asset management company with around 220 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 three 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. 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, we hosted dconf last year and will do so again this year. 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, 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.

Onin | JavaScript Engineer | Senior | Full-time | £50-75K | 0.25-0.5% F.D. stock options | London, UK | ONSITE or REMOTE (GMT +- 2h)

Our stack:

* Serverless (Lambda, DynomoDB, API gateway) * Node * React * Apollo GraphQL

We're building something BIG.

I wish we could tell you upfront what it is but we're in stealth. We can say if you love consumer applications and collaborative tools, we're your bag...

We're a small team of fun-loving, hardworking, software fanatics. We’re open and try new things with enthusiasm. And we’re high-momentum, focused on delivering magical products that our users love as much as we do. We socialise as a team at least once a month (currently via Zoom!).

Our CEO is Ryan Brodie, who co-founded muzmatch (YC S17) and has 3 successful exits.

We had somewhere to call home in a central London WeWork but since lockdown we're thinking about going fully remote with frequent company away days instead. What do you think?

We keep things simple and iterate fast, we use the best possible technology and tooling to realise our goals and improve our understanding.

Every hire, from our first to (one day) thousandth, gets generous equity. Everyone should consider this to be theirs as much as anyone else's. If you're not passionately arguing what you believe is best for our product, you might not be thinking as deeply as we do about our work.

We're hiring for engineering and product roles. If you want a job that doesn't feel like work, we'd love to hear from you. → ryan@onin.co

Tray is a visual programming platform. It’s a low-code user experience that allows anyone to build business logic that precisely defines how data flows through their organisation.

We recognise this is a stressful and uncertain time for everyone; Tray.io endeavours to stay strong during this period. We are well funded, with two recent rounds behind us; the latter to make a statement we wanted to remain independent, so we have a large cash runway. The goal of our Engineering team at this time is to come out the other side with an even stronger product so we are continuing to hire.

We’ve worked hard on creating a fantastic support layer and business continuity plans for our technical teams and we’re continuing to expand and empower. We are already used to working from home and you’ll find our calendars full of socially “distanced” events already and our leadership are leading regular company-wide updates.

We are excited by people who want to constantly innovate; borrow from other industries, experiment with new tools and pool their knowledge with other solution seekers; people who have shipped entire projects with ownership and autonomy; people who take pride in what gets built, all the whilst balancing day-to-day pragmatism with building for the future.
