Arachnys is creating a new global infrastructure for fighting financial crime. Our platform helps big financial institutions stop bad people doing bad things. That means everything from complex data ingestion and search challenges through to front-end user experience.

Our tech stack is mainly Python, React, ElasticSearch, Hadoop with some Golang and Java.

Email jobs@arachnys.com to apply - public code samples strongly preferred, CV optional. I'm the founder/CEO and still play an active role in the hiring process, so email (in my profile) directly if you have questions.

At Lightning Labs, we scale blockchains. Our current focus is the development and deployment of the Lightning Network[1], an open blockchain scalability protocol[2] primarily being developed for Bitcoin. Lightning allows for high volume, low fee, instant payments on top of Bitcoin. We strive to continually push the edge of innovation w.r.t blockchain scalability, advanced privacy-preserving smart contracts, and cryptocurrency UX. Amongst our team include applied cryptographers, the designers of the Lighting Network protocol, and several Bitcoin developers making key contributions to the open source Bitcoin eco-system such as roasbeef[3].

Cryto Protocol Engineer:

We're looking for an experienced software engineer well versed in applied cryptography, peer to peer networks, distributed systems, open source software collaboration, and cryptocurrencies. Your job description would include working on lnd[4] the most feature-complete implementation of the Lighting Network, neutrino[5] an advanced lite client operating mode for Bitcoin, conduct novel research into cryptocurrencies (and related areas), and helping to design the next generation of smart contract applications on Bitcoin.

Frontend Developer:

Our work on the second-layer of blockchains presents a number of UI/UX challenges, as we lift traditional wallets to the next layer creating a new application platform on top Lightning. As a result, we're also looking for a frontend developer that is able to pick things up quickly, develop skills in our interdisciplinary space, and has strong implementation ability. Applicants should be Javascript experts an eye for design, that have experience building applications with React and React Native.
