Ask HN: Who is hiring? (January 2016)

Semaphore CI | Europe | Full-time | REMOTE

Looking for senior software engineers into Ruby, Elixir, microservices and high scalability.

We’re on a mission to change how developers test and deliver software. Our way is to double down on great user experience and high performance, treat our customers as we’d like to be treated, and make continuous delivery practices more accessible to developers. CoreOS, 500px, Lexmark, General Assembly and many others use Semaphore (https://semaphoreci.com/about).

Tachyus - San Mateo, CA - many open positions We are revolutionizing the oil and gas industry, well funded, and (most importantly) producing significant revenue. This is the opportunity for the right people to align with us and share in ownership. We are a focused science and engineering driven team working with real physical devices and processes measuring and analizing the natural world. We take our Values statement seriously, so read it first and decide. http://www.tachyus.com/joinus/

As a technology company, our long-term success is dependent on the skill and alignment of our engineering team. We develop new software and hardware and rely on our engineers to bring the company's vision to fruition. Every engineer has the opportunity to make huge product contributions and has a responsibility to promote internal collaboration and adherence to best practices.

Software Engineer - DEVOPS

Our core physics and data science algorithms (what we call “Data Physics”) are written in a combination of Python and Matlab. Tachyus data physics algorithms solve large scale, difficult oil field problems using highly parallelizable, dynamic computation environments. The algorithms are typically developed on a Windows architecture but scale out to many Linux-based instances for deployment. These algorithms integrate with a full stack web environment running in F# and Typescript, which is deployed to Microsoft Azure and Google cloud environments. Both environments operate in parallel. We seek engineers who are excited to work on dynamic allocation of computation resources, efficient operations, and cloud-scale operations.

Correctness (QA) Engineer

The Tachyus Correctness Engineer is a Software Engineer who specializes in building the infrastructure to prove our software and algorithms produce accurate results. The CE works closely with the Software and Science organizations to prevent, catch, prioritize and eliminate errors in both software and data. Correctness Engineering is also intimately involved in continuous Integration and release management. He or she is an engineer at heart, preferably with experience writing production code.

Octopus Energy | Hammersmith, London, UK

We are a new energy supplier for the UK market, and we're looking for programmers (especially with Python experience) to join us. We're going to use Python to build a modern infrastructure for interacting with both consumers (via the web, mobile apps and smart-meters) and the industry (eg trading on the wholesale market, managing the billing life cycle).

To start with, we'll be using Django and the Django-REST-framework for the consumer-facing sites, and employing Pandas and Numpy for some of the heavier data processing required. We use AWS heavily, employing most of the Hashicorp toolset (Vagrant, Packer, Consul, Terraform) and are planning to use Lambda to build event-driven functionality.

This is a great opportunity for several reasons:

* We have lots of difficult design challenges to solve. The UK energy market is very complicated and process-heavy - there's an awful lot of domain modelling that we need to get right.

* We have difficult technical problems to solve. With the advent of smart meters, we'll soon be processing millions of meter readings a day. We need the right technology in place to handle this smoothly as well as feeding data into a machine learning pipeline that models and predicts consumption.

* There's a great opportunity for disruption in the UK energy market. The big suppliers still dominate, but are not exactly popular. The energy landscape is changing as we move to more disaggregated forms of generation, with less predictability, more dynamism and smarter technology.

* You'll be working for a company that is genuinely helping to make the world a better place. We'll be helping move people onto using greener technology and consuming energy from renewable sources. This will all help transition the UK towards a lower carbon future.

Our offices are in Hammersmith. We're open to some remote working but not 100% remote at this early stage of the company.
