London Jobs - November 2018

Zen Educate | Full stack engineer (React and Ruby) | London | Ideally onsite, but will consider remote | Full-time

UK schools spend over £2bn per year covering short-term absences with supply teachers. The current model is exclusively reliant on agencies that charge a massive commission and are terribly inefficient — everything is paper and phone-call based. We’re using technology to change this by building a marketplace to connect schools directly with teachers, pulling hundreds of millions of waste out of the education system.

We are well-funded by high-profile investors, have had significant early traction, and are led by start-up veterans behind two of London’s most prominent tech companies. As an early employee, you’ll play a significant role in the development of the company and have the opportunity for rapid career progression and learning.

We’re looking for a full stack engineer happy to work with React, Ruby and React native and who likes coming in each day working with a small, committed team on a mission for good.

We can sponsor visas if you’re interested in taking a move to London.

BBOXX | Software Engineer | London | Onsite

BBOXX provides affordable energy to off grid customers in sub-Saharan Africa using an innovative IOT based solar kit combined with cashless digital payments. We are looking for experienced developers to maintain and break our back-office solution into focused micro services.

Apply: https://bboxx.workable.com/jobs/774071

About BBOXX

Lack of energy access in sub-Saharan Africa is a significant problem, with more than 600 million people currently without mains electricity supply. In Rwanda, 9.5 million people or 81% of the population cannot access mains electricity, which has a negative impact on quality of life and limits people's chances of achieving economic prosperity.

BBOXX is helping to address this issue by providing off-grid communities in developing countries with affordable solar energy solutions. BBOXX customers typically use a Pay-As-You-Go payment method, which enables very low income customers access to electricity at home that they would otherwise not be able to afford. To date BBOXX has installed more than 150,000 solar systems and provided around 750,000 people with access to energy.

We are a top ten UK media publisher, with a website loved by millions: a technology company at heart with industry-leading success metrics propelled by a highly experienced multi-disciplinary engineering team that can afford to run lean. Which means today, we offer all the excitement and agility of a start-up, but with the stability and benefits of an established business — we’re still a company where everyone gets to make a massive impact!

Our mission: to democratise and disrupt the market for news. Today, we have major plans for growth, both here in the UK and abroad, and to create even more social capital out of what has been an extremely successful platform: through increased editorial direction, curating credible but independent journalism, as well as through computational approaches to identifying the best news to show our users.

We currently have these opportunities:

- As a /Designer/Developer/, you’ll be responsible for designing all aspects of the website UI and brand, and work closely with Head of Digital Product and senior management on the biggest redesign of our homepage in 20 years. You will be working with Adobe Creative Suite, JavaScript/Node/React, CSS3/SASS, HTML5, Responsive Web Design, progressive enhancement and feature detection.

- As a /Fully Remote Web Developer/, you’ll write the logic that drives the UI, and integrate new UI with back-end data. You’ll also work on a wide array of other UI/UX, SEO, and content integration challenges.

- As a /Fully Remote Full Stack Developer/, you’ll be expected to contribute authoritatively towards product development projects throughout the entire software stack: from database and infrastructure installation and configuration, through writing business logic and prototyping website presentation, to developing our bespoke programmatic advertising technologies.

- As a /Fully Remote News Algorithm Developer/, you’ll develop automated curation algorithms that will produce the content for a new homepage format.

- As a /Fully Remote Back End Software Engineer/, your projects will largely be server-side. You will bring a sophisticated approach to problem solving, finding ways to achieve objectives while addressing scalability challenges and security concerns.

All London positions are based at our centrally-located head office. All fully remote roles are open to UK residents only.

If you think you’re a fit for any of these roles, please apply online. http://www.NewsNow.co.uk/careers/

Podaris | Javascript developer | London, UK, | Remote | https://www.podaris.com/

Podaris is re-inventing how the world plans cities. We're developing a platform for urban infrastructure planning that combines elements of BIM and GIS, with a focus on agile, real-time collaboration.

We’re looking for a full-stack software engineer to join our growing team. You'll be able to make a big impact, joining a small but very enthusiastic team. For this role, you'll primarily focus on mathematical problems: computational geometry, parametric constraint solvers, network routing optimisation, etc -- problems that come up in the course of modeling both physical transport infrastructure and transport network simulation and analysis. However you should be enough of a generalist to be unafraid to dive into other areas of the application where needed.

Technology-wise, Podaris is built on Javascript/ES6, Meteor.js, OpenStreetMap, and OpenLayers. Your expertise with Javascript is more important to us than your experience with the particular libraries that we use. Experience with building large single-page apps is particularly helpful. Experience with Java-based OSM routers (and other associated or similar tooling) is also a strong plus.

We're based in London, UK, but are open to remote workers from anywhere in the world, provided we can establish a collaborative rapport. Currently we can only offer a six-month contract, but will aim to convert that into a salaried role pending additional funding. Equity is also available for extraordinarily talented individuals.

Permutive (YC S14) | Software Engineers | London, UK | Full-time, permanent, on-site, eligible to work in UK

Permutive is the simplest, most efficient way to integrate data-driven models into your product. We're a B2B SaaS company built on top of an innovative real-time data platform. We have product–market fit and customers that love us, and we're growing rapidly in Europe and the US. We raised a $10M Series A at the beginning of the year and have received funding from some of the world's best investors, including Y Combinator.

Everything we build operates at scale: our platform processes billions of requests a day across hundreds of millions of monthly end-users. We're developing a next generation data platform for a world with a trillion devices, and we think applying functional programming techniques like compositionality and type-safety is the best way to build these massive distributed systems.

You would be joining our core backend team on-site in London, working mostly with Scala and 'big data' ecosystem technologies (our full stack is below). We're happy to talk to people with a wide range of experience—from straight out of university to those with decades of experience—but you should have a genuine interest and preferably experience in FP, distributed systems, and stream processing.

Languages: Scala, Haskell, Elm

Libraries: Cats, Cats Effect, FS2, http4s, Shapeless, Circe, PureConfig, pipes, Servant

Technologies: Kafka, Kubernetes, Terraform, Bigtable, BigQuery, Beam, Postgres, Google Cloud Platform
