FlightAware | (https://flightaware.com/about/careers/) | Onsite (Houston, TX) or Remote (US) | Full Time

FlightAware is the world's largest and most sophisticated aviation data platform. We run a network of 30,000+ terrestrial ADS-B receivers, fuse 50+ third-party data feeds from around the world, process 180+ million messages per hour, track 100k+ flights per day from gate-to-gate or hangar-to-hangar, and run thousands of machine learning models in production that the world's largest airlines and airports rely on for daily operational efficiency.

I'm an engineering director at FlightAware running our "Aviation Insight" group, which is responsible for the architecture and reliability of FlightAware’s core flight tracking distributed infrastructure, the quality and accuracy of all flight and surface tracking results, and our end-to-end machine learning and model serving platform for computing live ETAs. We're expanding the group and hiring for a number of roles. If you're interested in distributed systems, machine learning, Rust, Python, Spark, or aviation, I'd love to hear from you.

## 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.

NoRedInk is used by 1 in 2 school districts in the US, and students have answered over 5 billion questions on our platform. If you're looking to join a team of friendly people who listen to and learn from each other, discuss past mistakes openly as we adapt to the challenges that come with progress, all while realizing our mission, then you'll be excited to learn more about us.

Our colleagues span six time zones, California to Berlin and points in between, with lively discourse flowing freely across Slack, Zoom, and the office when we're able to be there. Wherever we're working from, we've always deligted in our work to ship new features—beginning with our curriculum and product teams, designers, through to testing by our dedicated quality assurance folks—that put teachers and students first. [1]

Our engineering team [2] takes prides in producing innovative, maintainable software. We use the cutting-edge Elm programming language for all our front-end development. Our back-end is primarily Ruby on Rails, though we're actively moving toward Haskell services as we scale to keep up with our traffic. We use Amazon AWS for our infrastructure configured with Chef and OpsWorks, though we're migrating towards orchestration using Kubernetes. We write a lot of tests, and use Jenkins for continuous integration. We've also developed and maintain several useful open-source projects. [3] You can read about our experiences with these technologies on our team blog. [4]

We’re looking for engineers who want to work on a mission that makes a difference and who are the type of collaborators that value kindness and open-mindedness. If that's you, you can learn more about our interview process [5] and on-boarding experience [6], and you should definitely apply through our jobs page! [7]
