## 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.

Primer | Data Engineer, Front/Back End Engineer, Technical Lead, Software Architect | 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 our customers to accomplish this much faster without having to engineer an expensive system.

Here are some reasons to work with us:

* We bootstrapped ourselves to $700k in revenue with a team of 4 in 2020 and just raised a small round to grow.

* We invest in our team and catapult careers. Many people end up at top-tiered companies like Dropbox, Facebook, and Tesla beyond working together.

* Our team is fully distributed, supports flexible schedules, and we spend 95% of our time outside of meetings. Many of us have young kids and we prioritize work/life balance.

* Our engineering ceremonies and technology are world-class, put engineers in the drivers' seat, and emphasize transparency.

* Our culture is high-achieving, genuinely kind, and collaborative.

The roles we'd like to fill are:

* Data Engineer (ETL/API)

* Technical Lead / Software Architect

* Senior Software Engineer (Back End)

* Software Engineer (Front End, Back End)

We welcome all applicants. The only requirement is having 1+ years of professional experience.

Our stack is React / Javascript / Node / Postgres, but we welcome polyglots. In general, we're looking for thought partners to help us architect a solution for the future so experience with other languages (e.g. Elixir, Go, Clojure, Kotlin, Haskell, Rust) is a plus.

NoRedInk | Full-Stack Engineers, Growth Engineers, Platform Engineers, Engineering Managers, Quality Assurance (QA) Engineers, and Tooling & Infrastructure Engineers | REMOTE from time zones between (and including) Pacific Time (PST) through Central European Time (CET)

We’re a growing ed-tech company on a mission to help all students become better writers! 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 delighted 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 by lines of code, though we're actively moving toward Haskell; the majority of our traffic now goes through a Haskell service. We use Amazon AWS for our infrastructure orchestrated primarily 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]

MuKn | Remote, all timezones | Full-time or contract | https://mukn.io/

Mutual Knowledge Systems, Inc. (aka MuKn, pronounced "moon") is looking to extend its development team. We are implementing Glow (https://glow-lang.org), an open-source domain-specific language to build Decentralized Applications (DApps). Glow simplifies DApp development by offering higher-level abstractions than standard solutions (e.g., Solidity) and a "write once, run on- and off-chain" workflow.

Specific problems we need to solve in the very near term include (a) implementing monadic blockchain infrastructure in Rust (malleable transactions), and (b) augmenting our compiler with formal verification of contract properties. We are looking for experienced developers who can work autonomously, but know when to ask for help. For (a) Rust experience is a must, and (b) requires a strong background in compilers, formal verification, and modal logic. We like publishing our results, so one or both of these projects could result in journal papers.

Glow’s metalanguage is Gerbil Scheme (https://cons.io), but we use other languages where necessary, including JavaScript, Haskell, and Rust. Some background in Lisp, Scheme, or a purely functional family would be helpful, but is not required; experience with language design and implementation is also a plus. Other relevant domains include: blockchains, smart contract technologies (e.g., the EVM and also (E)UTxO models), distributed systems, cryptographic protocols, information security, economic modelling, game theory, automated theorem proving, and zero-knowledge proofs.

We’re a fully remote team spread across many time zones. We like to keep meetings and policies to a minimum, and expect team members to manage their own time and communications. We have one mandatory weekly meeting, structured as an informal code walk-through and review; this helps keep everyone aware of what the rest of the team is up to and how everything fits together.

Please send resumes to jobs@mukn.io. Any notable public discussion (on a mailing-list, GitHub issue, etc.) where you changed your own mind or someone else’s mind would be great to see, too.
