Man Group Alpha Tech | Quant Python Engineer | London, UK | Onsite | Full Time

As a Quant Python Engineer in Alpha Tech at Man you will be building the tools, frameworks, libraries and applications which power our Quantitative Research and Systematic Trading. This includes responsibility for the continued success of “Raptor”, our in-house Quant Platform, next generation Data Engineering, and evolution of our production Trading System as we continually expand the markets and types of assets we trade, and the styles in which we trade them. Your challenges will be varied and might involve building new high performance data acquisition and processing pipelines, cluster-computing solutions, numerical algorithms, position management systems, visualisation and reporting tools, operational user interfaces, continuous build systems and other developer productivity tools.

Our systems are almost all running on Linux and most of our code is in Python, with the full scientific stack: numpy, scipy, pandas, scikit-learn to name a few of the libraries we use extensively. We implement the systems that require the highest data throughput in Java. For storage, we rely heavily on MongoDB and Oracle.

We use Airflow for workflow management, Kafka for data pipelines, Bitbucket for source control, Jenkins for continuous integration, Grafana + Prometheus for metrics collection, ELK for log shipping and monitoring, Docker for containerisation, OpenStack for our private cloud, Ansible for architecture automation, and HipChat for internal communication. But our technology list is never static: we constantly evaluate new tools and libraries.

Alpha Tech has a small company, no-attitude feel. It is flat structured, open, transparent and collaborative, and you will have plenty of opportunity to grow and have enormous impact on what we do. We are actively engaged with the broader technology community.

o We host and sponsor London’s PyData and Machine Learning Meetups o We open-source some of our technology. See https://github.com/man-group o We regularly talk at leading industry conferences, and tweet about relevant technology and how we’re using it. See @manquanttech Essential Skills o Exceptional technology skills; recognised by your peers as an expert in your domain o A proponent of strong collaborative software engineering techniques and methods: agile development, continuous integration, code review, unit testing, refactoring and related approaches o Expert knowledge in one or more programming languages, preferably Python, Java and/or C/C++ o Proficient on Linux platforms with knowledge of various scripting languages o Strong knowledge of one or more relevant database technologies e.g. Oracle, MongoDB o Proficient with a range of open source frameworks and development tools e.g. NumPy/SciPy/Pandas, Pyramid, AngularJS, React o Familiarity with a variety of programming styles (e.g. OO, functional) and in-depth knowledge of design patterns.

[still-unnamed startup in stealth mode] | REMOTE or ONSITE(around HK: Guangzhou,Macau,Shenzhen,Taiwan,etc) | 20-40h per week, freelancers/full-timers/part-timers

Sorry for the vague description but I can tell you more about the product we're building when you apply. Hopefully I can attract you in a sufficient way with our tech stack! (see below). [NOTE: this is not a pie-in-the-sky venture, you would be joining a team who has a 1.5+year-old working product, with prospects of new greenfield products built around the first.]

Job positions:

- Build engineer: you are a Linux-er who has some past experience building deb or rpm packages, are excited about reproducible builds, and are willing to learn (if you don't already know) new things such as snap or flatpak. gitlabCI and/or githubActions is a plus. (Might do some DevOps work after we come out of stealth mode as well; with Pulumi and RedShift.)

- C#/.NET developer: generics, LINQ, VisualStudio, EntityFramework et al are your bread and butter. You value the diversity that comes from learning other languages and tech-stacks but also the stability that a robust platform like .NET provides, which you based your career on. Desirable to be familiar with Xamarin, but not required. F# is a plus.

- Rust developer: you dealt with C/C++/Objective-C in the past but are ready to move on. However, you're still not convinced about garbage collected languages, so you have been looking at Rust lately, or willing to learn it. You're not a smart-ass though, so you would be excited to expose your Rust code's API to be consumed by higher level languages.

- FP developer: you value immutability and lack of side effects because you have lived the nightmares of race conditions and heisenbugs in your career. You're disgusted with most job positions out there because the tech-stack described in most of them don't look safe enough to be serious (sure they can build snapchats with them, but not robust software that would end up being used by NASA or Waymo). Desirable to be familiar with F#.

- Desktop/mobile developer: you cringe at the idea of "Electron apps", because you think native frameworks like QT or gtk+ give much power and maintainability (plus, performance aside, javascript is a joke in any other aspect too). But you also understand why garbage-collected languages are safer and more productive than low-level ones, and there are many of these much more decent than JS. (gtk is preferred for this position at the moment; or someone willing to switch)

- SmartContracts/blockchain developer: you've used/developed smart contracts in languages such as Ivy, MiniScript, or Solidity(EVM), or are willing to learn this technology. Desirable to have familiarity with atomic swaps, HTLCs or zero knowledge proofs. Excited about things like bitcoin-lightning, ethereum, mimblewimble/grin, DAI, etc

Important perk for all positions: all the code/scripts you'll write (being paid of course) will be opensource, at least for the first 2months.

Write me at andrew.forsure@gmail.com

PS: Abstain from applying if you expect a lead/managerial role, because the team is not yet big enough to need extra leadership for now.

PS II: In case you're only interested in joining part-time, note: I wouldn't find it acceptable if you join us to work remotely part-time while keeping your full-time job. Part-time only works with your own side-projects, or other additional part-time job (because resting is important).

International Brain Laboratory | Software engineer, IT Support Officer | New York, Lisbon, or London | Full-time | https://www.internationalbrainlab.com/opportunities#jobs

The International Brain Laboratory has openings for postdoctoral fellows and scientific staff who will play key roles in a new large-scale international collaboration in brain research.

The IBL combines the efforts of approximately 50 scientists in 20 laboratories toward understanding the brain-wide basis of a complex behavior.

The project will involve recording the activity of millions of neurons in the working brain and building mathematical models of the resulting data. The data sets this project will produce are vast and complex, including physiological recordings, behavioural measurements, and video, all of which must be standardized into common formats, integrated into a single database, and subjected to quality control. Core staff positions will support the both experimental and theoretical work through the entire data life cycle, including acquisition, analysis, modeling and dissemination.

Remuneration will be competitive and commensurate with experience. There is considerable flexibility in base location within the U.S. and Europe.

Technical environment: Python, Django, PostgreSQL, NumPy, MATLAB, C, OpenGL, hardware & electronics...

* Good understanding of C and x86-64 assembly

* Good understanding of the x86 architecture

* Good understanding of the Windows NT kernel

* Good grasp of reverse engineering

* Eager to learn

Nice to have:

* Experience with reverse engineering malware/cheats/games, the windows NT kernel

* Experience with binary instrumentation

* Experience with hardware-assisted virtualization (such as VT-x and AMD-V), SLAT (Second Level Address Translation) (e.g. EPT, NPT)

* Understanding cryptography primitives

The role we’re looking to fill is full-time. You’ll be working together with another anti-cheat engineer to combat cheaters in video games. We can offer relocation to Sweden and assist with housing. Feel free to mail me at asamy@doctype.se if this sounds interesting to you!
