You build internal processes that are so reliable they melt into the background but are key to getting work done.

APIs
You've been on the receiving end of APIs good and bad, and want to delight our customers with the high quality they expect. You know that whilst everything should be JSON, sometimes you have to get your hands dirty with some SOAP for that critical integration but know how to isolate the contagion.

• You will have a chance to learn from many experienced engineers with various technical backgrounds
  
• You will help take Pusher’s flagship new product through a period of significant growth, encountering many engineering challenges along the way

What you will typically do

• You will become the go-to expert for at least one large area of the codebase
  
• You will need to be able to work comfortably solving ambiguous and complex problems

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.

Given the very early stage of the new architecture they are building, you will have significant influence over the processes, tools and design decisions ranging from the development of their CI/CD pipelines to the use of Machine Learning, Big Data pipeline etc. A commitment to collaborative problem solving and product quality is essential.

Experience

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.

Our Technology

Technology is at the heart of everything we do at Fat Llama, allowing us to solve a problem that has never been solved before. Our whole team gets a say in the product & tech roadmap, and our engineering team takes pride in writing, testing and deploying new features on a daily basis.

As an engineer at Fat Llama, you’ll be responsible for crafting, building and running the software which underpins our marketplace. We’re looking for somebody that can deliver solid engineering whilst moving at the same speed as our constantly growing business. You should also be excited about helping shape the direction and culture of our engineering team going forward.

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.
