Golang Senior Jobs in London

Job Description

We are looking for a skilled back-end developer who's passionate about tech, startups and entertainment to join our growing global team, and has extensive experience with the following:

• OO/MVC PHP frameworks (such as Laravel and Symfony - we use a framework similar to these)
• Node.js
• Golang

You'll be working on technology that huge festivals and conferences will use to predict new trends in audiences and event attendance, automate highly-targeted ad campaigns, turn traditionally-complex workflows into incredibly intuitive event management, marketing and CRM tools, and more!

Some front-end Javascript experience would also be preferable (particularly for building client-side SDKs that need to work within cross-domain/browser security models). Lua/embedded scripting experience is also a bonus.

Your role will be to maintain and add functionality to the existing PHP code base, powering both consumer workflows and APIs that power our React-based admin dashboards. This will range from creating business logic to building complex reporting tools, payment gateway integrations and more.

Over time, you will also take part in refactoring/rebuilding parts of the PHP code base into more advanced Node.js/Golang versions.

Ideally, you will also have experience of building systems that can support high concurrency, with robust inventory locking, with the right technology components for each use case (such as Redis, CouchDB/Cloudant).

Some tasks will involve you working with our Devops engineer to create highly-scalable and redundant systems.

We are a young, fun company, funded by some of the best investors in Silicon Valley and our clients are cutting-edge events companies who partner with us to take them to the next level.

If you want to help us to be the next phase of a multi-billion dollar industry, we want to hear from you!

Job Description

Pusher’s realtime APIs power applications around the world across various industries. When you see an in-app chat, a collaborative text editor, or anything else that updates instantly—it could be us shifting events behind the scenes. This role is specifically for the Chatkit team, where we are aspiring to be the industry leader of all chat SaaS by empowering developers to add chat functionality in a fraction of the development time.

As a Chatkit Engineer you will:

• Massively scale up the core of Chatkit services
  
• Influence a long-term technical roadmap for the product
  
• Mentor the team to help make Chatkit the industry-leading chat API

What you will be able to learn

Great software engineers never stop learning, so we want to provide you opportunities for improving your knowledge. As a Chatkit Engineer:

• You will get to learn and use leading-edge technologies, like Kubernetes, in high-traffic production environments
  
• 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
  
• You will need to dive into both new and familiar areas of our code to support more inexperienced members of your team, and communicate effectively whether it be pair-programming, in a code review, or in a proposal for a new improvement or service
  
• You will be a member of the on-call rotation, and be expected to follow through with suggestions for how to prevent future system outages, or implement self-healing systems
  
• You will determine how to track and implement metrics of quality and drive improvements to our benchmarking process

• The Chatkit team subscribes to the lean methodology. We work in short iterations with as little bureaucracy as possible. We value continuous improvement and expect team members to voice their concerns early and often so that we may address things before they become problems.
  
• The Chatkit team breaks down silos through collaborating, information sharing, and pairing. We rotate ownership of interesting problems like benchmarking, and encourage pairing on new proposals and SDKs.

What Pusher is like

We strongly believe in the importance of diversity and inclusion. They not only provide a better working environment but also improve the quality of our services. We welcome people of different nationalities, backgrounds, experiences, abilities and perspectives.

We are here to help our customers build delightful applications. By solving significant engineering challenges and packaging them into easy to use APIs, we let developers focus on making their users happy.

We put emphasis on collaboration between people and teams. Everyone is on the same mission, so sharing work helps us reach our goals faster. Throwing problems over the wall and pointing fingers at each other is not our style.

We strive for transparency. Keeping everyone well-informed is crucial for building trust, efficiency and satisfaction at work.

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.
