Ask HN: Who is hiring? (January 2018)

We are building the software platform that powers the the solar industry. Our clients are companies that work on transitioning our society to a future of sustainable energy by selling, designing and installing solar installations. Aurora enables them to do their job better, faster, and more efficiently. Aurora is a cloud-based SaaS solution that allows solar installers to build 3D models of buildings and trees, simulate the impact of shading on a homeowner's roof, design advanced solar systems, calculate the financial return of a solar system and generate beautiful sales proposals. By enabling solar installers to do all of this in a short time and without having to leave their office, Aurora helps to reduce the cost of solar installations and make solar energy more widely available.

Rentify is an online letting agency that uses technology to make both landlords' and tenants' lives easier (and cheaper). We offer landlords guaranteed rent based on an algorithmically determined property valuation, and attribute most of our savings to efficiently using technology to solve the many moving parts of property rentals.

We're looking to add some junior to mid Ruby/Rails/Javascript engineers with at least 1 years commercial experience, to our in-house engineering team to help us build both public-facing and internal tools.

Recent projects include building an internal ticketing and task management system using React and Rails, and an iPad app for property valuations and check-ins using React Native and Rails.

Our main app is Ruby on Rails with PostgreSQL as a store, hosted on AWS. Other technologies we use every day are Elasticsearch, React, Chef, Sinatra and Redis.

We're a modern betting exchange, going technology first to enable proper price competition in a field of fat commissions. Join a small, agile, and fast-growing team, in our beautiful office in St. Katharine Docks. If our US location tickles your fancy, you get to help setting up a brand new office too.

Smarkets develops a reliable, low-latency, highly concurrent betting exchange based on trading exchange designs. We're also building a fast, modern web interface to allow for a smoother experience. Servicing our users is top priority.

The Smarkets platform is written predominantly in Python and Erlang, and relies heavily on asynchronous programming techniques. We use REST where we can. Life at Smarkets circles around people, version control, configuration management and automation. We can - and do - deploy to production several times a day.

Our entire production is in AWS. In fact, Smarkets was the first gambling operator under the Maltese regulator to get permission to run everything in the cloud. We push the envelope where needed and educate auditors when necessary.
