London Jobs - June 2021

FDB Systems | Full stack engineer | London based, Remote OK, UTC+/-3 | https://fdb.systems

FDB Systems builds data products for hedge funds and other investors - we have a growing portfolio of niche data products (e.g. https://filingdb.com/) and we also create bespoke data solutions for clients. Our core team has deep domain experience having worked for tier-1 funds (on the discretionary and systematic sides) and at other successful startups prior to starting the company. We launched our services just before the pandemic but have nevertheless seen strong growth and we now count some of the world's best funds among our clients. The company is revenue and cash generative with a very strong balance sheet - we are funding most expansion organically through revenues but, in addition, we have raised a small amount of money from excellent investors and have won a research grant for the past year.

As the first tech hire, you will:

* take ownership of parts of the stack

* be involved in architectural decisions

* work on improving our tech and process to handle the global expansion of our main data product.

This is a great fit for anyone who likes building well-running, efficient pipelines.

Tech stack:

* Python backend

* AWS for infrastructure

* React for internal tooling frontend

We are a small company and we are genuinely passionate about our space and finance more widely. If you have an interest in finance (in whatever form) and want to experience developing and improving products for some of the best funds in the world, we think you would enjoy working with us. We are an early stage company and that means everything you do will have an immediate and lasting impact on the business: you will be able to work on a variety of projects, with real ownership of core elements and very little management overheads to deal with. We are positioned as the highest quality provider in our space and this focus on quality runs through our entire culture - we really enjoy our work and spending time with colleagues but our environment is a professional and respectful one.

If all this sounds like a good fit for what you're looking for, shoot us an email at bogdan@fdb.systems with a resume and, optionally, any projects you are happy to share.

Bolt6 | UK/EU Remote (UTC to UTC+2) | Full-Time | C++ Computer Vision & Deep Learning Engineers

We are a funded sports technology start-up founded by industry veterans that is looking to expand our engineering team to take on exciting new projects. We use computer vision (both classical and deep learning) to extract data from raw camera feeds that is then provided to our customers (think sports leagues and broadcasters).

## 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.

Mux (YC W16) | SF, London, REMOTE (US, CAN, and UK) | Full-Time | Elixir, Golang, TypeScript/React | https://mux.com/jobs

Mux is how developers build online video.

With Mux Video, developers gain access to a powerful API for video streaming--think Stripe for Video. You don't have to have strong feelings about ffmpeg settings, you just go. And with Mux Data, developers realize incredible insights into how their videos perform from platform to platform, place to place, and user to user.

I'm Ed, and I'm an engineer on the DevEx team here - you might have seen me around HN here and there. ;) This is, and I have to stress that I'm not kidding because everybody says this sort of thing, for real my favorite job that I've ever had. The team here is mind-blowingly smart, there is a real and concerted focus on not just competence but on the human side of things; one of the company's core values is "be human" and I thought it was marketing stuff 'til I joined and learned to my surprise that it is emphatically not. Also? Legit, the best onboarding experience I've ever had. During a pandemic, no less.

The tech stack actually manages to balance cool with useful, too. It's a multi-cloud environment running Kubernetes on AWS and GCP, with Elixir, Golang, and some NodeJS (some JS, mostly TypeScript), plus React and TypeScript for all the usual bells and whistles.

Mux is a good place to be and if video is your bag, or even just sounds interesting, you should check us out. At the moment our hiring is limited to the US, Canada, and the UK. Feel free to head on over to https://mux.com/jobs and check out our openings; we run a pretty standard interview-loop process and I don't feel like we waste candidates' time. Even if you don't see an immediate spot that clicks with you, feel free to reach out anyway; we have a certain facility for finding room for amazing people.

At Tessian, we're building machine-intelligent filters to secure enterprise communications. This involves high volume, low latency data processing for some of the world’s largest organisations. Our mission is to keep the world’s most sensitive data private and secure - to do this we're bringing on all stripes of engineer to help build out our platform to support our next stage of rocket-ship growth.

Principles we believe in:

- Infrastructure as code (mostly Terraform)

- Unit Testing & Integration Testing (NUnit, PyTest, Mocha)

- Continuous Integration, Continuous Deployment (using Concourse)

- Designing security in (rather than testing for and adding it later)

- Measuring everything (ELK & Prometheus)

- Reproducible builds and environments (if it’s in production, it’s in Docker)

- Cloud Deployments (AWS gives us the flexibility we need to move fast)

- Right tool for the right job (PostgreSQL, Spark/Hadoop, Redis, Elastic Search)
