• You choose your kit
• Pension & Health insurance
• Flexible working
• 28 days holiday + bank holidays

Job Description

Our mission is to give every person on the planet fast and affordable internet. We remove traditional internet infrastructure costs by developing technology which allows any device to be used as a cloud server. Using this tech, we will build a global distributed cloud platform. We are working at the forefront of distributed systems, peer-to-peer networking, and cloud systems.

Flare’s first product is a peer-to-peer CDN, designed to be faster and cheaper than incumbents. We are looking for someone to help us tackle the scalability challenges around our product. You will help us design and build out our caching, messaging, and routing systems to work across millions of nodes. You will have significant input and control over the architecture of these systems, to help us ensure that they are scalable, reliable, and fast.

We raised a £1.1m seed round earlier this year, and are backed by some of the original investors of Protocol Labs, Transferwise, and Zoopla. We have already partnered with industry heavyweights like the Guardian Media Group (one of the largest media platforms in the world), and our advisory board includes the ex-CEO of BitTorrent, ex-CTO of Shazam, and one of Akamai’s founding architects.

You will be a core team member in a fast-moving startup, working alongside talented engineers to build and ship a product that will be used by millions. You will be one of the first employees at Flare, and you will have direct input over the architecture and design of Flare’s systems. It is an unparalleled opportunity to grow and learn in a startup environment, and have direct impact on Flare’s direction.

We are looking for someone who has built and deployed performant and distributed systems at scale (preferably in Golang). We expect that you have experience working with the major cloud providers (AWS/GCP), ideally in high-load systems. You should be familiar with CDN architectures (caches, origin servers, proxies, etc), the networking stack, and the infrastructure of the internet.

Job Description

What if owning things was no longer important? What if expensive, niche items could be available to you in seconds? And what if you could generate an extra income from your own belongings? At Fat Llama, we're already bringing about that future. We believe that one day, owning those things we only occasionally need will be as ridiculous as buying a house every time you want to go on holiday.

Our users enjoy on-demand access to anything from high-end cameras to drones to campervans. As a result, they're doing, creating and achieving incredible things every day. Income from rentals is changing the lives of many of our lenders, too - whether it's paying their rent or allowing them to drop corporate jobs and focus on passion projects.

The herd's growing fast, too. Last year we went through Y Combinator and recently announced a $10M raise from amazing investors to superpower our growth and focus on American growth.

Are you excited by the prospect of learning new technologies? In a rapidly changing and growing startup, you’ll be required to wear many different hats. Whether it be designing scalable systems, building tools to help our Operations team keep the business running, or slicing and dicing data for our analytics dashboards, you should welcome the challenge. You should thrive in a constantly changing environment and enjoy learning new things at a fast pace.

Our team takes pride in owning our work truly end-to-end. We’re looking for people who can plan, experiment, build, test, deploy, measure and iterate before calling it done. As a small team, we try and build on the shoulders of giants, which means that you’ll often find us working with the latest and greatest technologies.

You might be a good fit for the role if you:

• Want to work in a team that values teamwork, learning and collaboration.
• Love writing clean, elegant code that other people can read.
• Have a deep understanding of at least two programming languages or paradigms.
• Have experience mentoring and teaching other engineers.
• Have led engineering projects from conception to delivery
• Have expertise in designing and building web services or APIs.
• Take pride in your fastidious approach to testing your code.
• Have a real passion for user experience. Every. Llama. Counts.

We would be thrilled if you also had:

• Experience building distributed systems or microservices.
• Android, iOS or React Native work under your belt.
• A deep understanding of JavaScript or Golang.
• Experience working with and launching cloud based services.

If you don’t feel like you fit all of these areas, don’t worry. We are dedicated to the development of our team. Whether you’re a computer science graduate, an artist or a bricklayer, as long as you’re also a programmer, we’d love to hear from you.

Please note that the package for this role will include equity.

Applicants with less experience may want to consider applying for our software engineer role.
