London Jobs - April 2018

Trivium Real Estate | Frontend and Devops | London | Full-time | ONSITE

We're a young, investor-backed, machine-learning startup for the commercial real estate industry (proptech). Our MVP is moments away from launching and customers are queuing to take it for a spin. As such, we're growing our team to tackle the challenges ahead.

We're a team of 8, located at London's South Bank and value continuous learning, empathy with our clients and customers, and empowering our engineers to make the best decisions.

# Front-End Engineer

This is for someone who:

- is comfortable in functional programming, especially Elm; and

- is experienced shipping front-end software to production; and

- has empathy for users and loves friendly UX; and

- has an eagerness to learn and willingness to share knowledge.

## A Typical Day

- Start off writing a feature that requires elm-ports. These can be tricky, so you pair with another developer who has shipped such code before.

- After lunch you're requested to review a Pull Request that fixes a bug you accidentally introduced a couple weeks back. There's no blame, instead some discussion about how our tests and review process could have caught this earlier.

- The afternoon is spent with the Product guys around a whiteboard. You're helping them sketch out a realistic wire-frame for a feature we plan to deliver in a couple of weeks.

# Dev-Ops Engineer

We're believers in CI and automated testing, but we need some help getting there. In particular we spend far too much time:

- Ensuring our testing, deployment, and validation services are up to date with the product.

- Managing different servers for staging and production.

- Trying to ensure we have a consistent build process across different machines.

- Thinking about the best way to deliver our machine-learning services in production.

You should have:

- experience maintaining CI services;

- experience writing web applications in a functional language;

- experience with different build processes (e.g. Make, `webpack`);

- knowledge of and comfortability with Linux, AWS, and Docker.

# Some Tech we like:

We're more interested in a willingness and ability to learn than what you currently know. But in case your interested in the stack we're using:

- Haskell

- Elm

- PostgreSQL

- Python / scikit-learn

- Tensorflow / Deep learning

- AWS

- CircleCI

- Automated Testing

PolyAI | London/Singapore | Onsite/Remote

PolyAI is building the backend machinery to allow computers to have two-way conversations with people. If you've used Siri, you'll probably know that it's okay at handling single-sentence commands like "remind me to call Jane in 2 hours", but anything significantly more complicated - anything that requires a 2-way conversation to establish what you want - is much much more flakey and inconvenient. At PolyAI, we're building the first developer platform for making scalable, maintainable voice apps that rely on conversations, rather than just single-commands. This opens up the possibility of Alexa/Google Home skills for Deliveroo, Uber, Postmates etc that are actually convenient to use and "just work".

We think this is the first step towards a future where voice interfaces are the de facto way of carrying out small to medium sized tasks.

We're a small but fast growing team of 8 people, comprised of (really good!) NLP researchers, and software engineers with a bunch of startup experience behind us. We're healthily funded by Passion and Amadeus and pay competitively.

We're looking for:

* backend engineers * machine learning/NLP engineers

I just want to point out that while we are currently a team of all men, we are super keen to move away from that, and regularly introspect about whether there's anything about our culture that may in any way exclude non male candidates. Additionally, we are always open to feedback about anything we might be getting wrong here.

Sphere | Full Stack Engineer | London, UK | ONSITE, Full-time

Sphere is building the future of mental health support

Currently, mental health support is only available if you're "diagnosed" and even then, huge barriers exist to accessing support - emotionally, financially and logistically. NHS waiting lists are more than 9 months to see a counsellor and private therapy is only really viable if you have the money to spare or are really in need. In short, support is archaic and inaccessible.

We set out to build mental health support for how people live today. We offer message chat-based support and allow you to receive ongoing therapy from a counsellor. In a really short space of time, we have built the product and are already supporting thousands of people. We've also just raised our first round of funding and taken on some truly incredibly talented people into the team.

We're using React Native/Redux and are design led as a company. We're looking for an engineer who is driven work on a really exceptional product.

Please email your CV and a short paragraph on why you're interested to calvin@sphereapp.org

Thanks!

Endjin| UK | Full-Time, UK | https://endjin.com

Are you interested in working for a company where you learn something new every day? Where you get the chance to engage with industry leaders and Microsoft product teams to solve cutting-edge problems for our clients?

Endjin are hiring developers at all levels, from apprentices to seniors, to work on exciting projects with clients from all over the world, in verticals from retail to financial services, utilities and media.

Endjin specialises in digital transformation using Azure, Data & AI. We have built 100k+ core Azure grids, and petabyte-scale storage solutions. We've produced machine learning algorithms that find the anomalies in hundreds of millions of device messages, or built bots that help a person sell their watch online.

Endjin was incorporated in 2010 by two founders wanting to create a sustainable long-term business with organic growth delivered by deep partnerships with our clients.

Since then, we've helped organizations of all sizes, across many industries to transform how they invest, envisage, build, deploy, test, manage, and grow new digital offerings.

We also structure innovation programmes, process improvement, and DevSecOps, as well as delivering production-ready code, cloud infrastructure, and thought-leadership content.

We value life-long learning and an eye for quality. We will help you to find the best learning techniques, tools, and team-working, so that you can achieve your potential, and deliver the best value to our clients; while balancing your personal goals and home life.

Our employees have a mutual respect, regardless of where they are in their career. Ideas are developed by the whole team, from interns to seniors.

Equally, our clients pass the "nice to work for" test (and usually do so with flying colours). As part of that, we try to understand the ethical implications of the work we undertake. We seek to do the best we can for each other, for our profession, clients, and for the world at large. With no external investors, endjin has been built as a sustainable, lifelong business: we are a company to retire out of, not exit at the expense of the employees.

You can work remotely from anywhere in the UK, with hubs in Cambridge, Reading, Hampshire and London. We hold meet-ups in London on a regular basis. You design your ideal working environment, and we will make it happen together.

Apart from a real passion for learning, you know a couple of programming languages pretty well (we do a lot of C# and Typescript, but you may know R, or Python too). You love working with other people, but value the opportunity to spend time in your own head, thinking things through.
