Strike's mission is to build a more connected financial world.
Strike allows users to send and receive money anywhere, instantly, with no fees.

Strike believes that open payment networks enable universal participation in the financial system, ushering in a new digital economy with truly borderless money transfers. Strike leverages Bitcoin’s open payment network to offer users the first global peer-to-peer payments app and a novel bitcoin-native neobanking experience.
Strike is looking for a world-class infrastructure engineer who has experience building robust, scalable and secure systems.

The first implementation is the Bitcoin Beach wallet deployed in El Salvador. This is currently the second wallet in the country. More context here.
In the following year, we’ll deploy new wallets in developing countries, in Central and South America, Africa and SouthEast Asia.
We are looking to better understand:
We are looking to both build real time dashboards that will track selected metrics in real time, and also do some deep dive analysis into our users cohort to better understand user behavior.
We are witnessing the first country going to the bitcoin standard so we probably have a lot of relevant data to understand, with insights we want to share with the broader bitcoin community on best practices for converting a community and a country to a bitcoin standard.

Roles:
- Write advanced software tooling for automated channel management and initial client channel selection (autopilot)
- Implement algorithms for ongoing capital management and optimization (fee maximization and capital efficiency)
- Design and maintain a suite of monitoring and alert infrastructure for routing nodes
- Develop and collect metrics to passively analyze of the health of the network based on graph and node level signals
- Design and build novel systems designed to help nodes/users acquire and manage liquidity on the Lightning Network
Skills:
- Experience building and operating secure, scalable, highly-available systems
- Experience developing and supporting publicly available APIs
- Familiarity contributing to open source projects preferred

Our work on the second-layer of blockchains presents a number of UI/UX challenges as we lift traditional Bitcoin wallets to the next layer, creating a new application platform on top of the Lightning Network. As a result, we're looking for a frontend developer to build out the key applications, libraries, and tools for the masses to interact with Lightning. Our applications are built on React, React Hooks, MobX, and EmotionJS, communicating with a Lightning daemon over a binary RPC protocol. Ideal applicants should have experience building and shipping React applications and maintaining open source projects. This role requires contributing to an open source project with a growing number of active contributors, and involves serving as the primary driver for the design and development of the project.
