Golang Distributed Systems Jobs in United Kingdom

Job Description

Ravelin is looking for a senior backend engineer to lead the development of a high volume fraud technology platform within a small tech team. You will be invited and expected to have opinions about the strategic direction of the company and products, as well as leading the development team from the front. A successful candidate will be willing learning new skills (machine learning, neural networks, python, golang, cloud automation etc), turning their hand to necessary tasks and working with complete autonomy.

Responsibilities

Code for Humans

Your machine is happy if it compiles; your team is happy if they can understand what it does. Your pull requests are succinct and a pleasure to review, you have unit tests where it matters, and you understand that the code is not, in fact, the documentation.

Reliable & Resilient Software Not for you the happy path or the assumed network. That habit of yours of assuming the worst and planning for it has earned your stripes in the world of running software at scale under real-world conditions.

Tools for the Team
Whether it's a smart command line utility or a core internal library, you excel at improving everyone's lives by removing repetition & common sources of error, and by solving hard problems in accessible ways. 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.

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
  
• You will also be a member of the customer support rotation during normal business hours. The Chatkit team believes in providing the best possible customer experience. In these early stages of the product lifecycle, we get firsthand insight into the challenges, complaints, and excitement of our customers through a customer support rotation

What working in the Chatkit team looks like

• The Chatkit team uses a modern tech stack. Our services are written in Go and deployed on Kubernetes. Pusher uses and supports many other projects from the Cloud Native Computing Foundation.
  
• 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.

Perks & Benefits

• Competitive salary
• You choose your kit
• Pension & Health insurance
• Flexible working
• 28 days holiday + bank holidays
• Free breakfast, snacks & drinks
• Monthly lunch
• Regular social events
• Yoga & Massages

Job Description

Core platform

When we refer to the "core platform", we mean the services which underpin the processes of all insurance activities on our system.

For example, we expect one of these to be the "policy service", which might be responsible for ensuring compliant issuance of policies, coordinating mid-term adjustments, preventing overlapping policies (double insurance), etc.

Other services could include user authentication, risk & pricing calculation, handling the process of modifying user data in-line with any mid-term adjustment requirements.

All services we consider to be part of the core platform will have strict requirements around stability, data integrity and transactional safety. All functionality must fail safely and explicitly, for example using 2-phase commit processes or other similar techniques. This will also require a reasonable level of testing to validate this safety.

Requirements

The perfect addition to our team will have:

• a fiercely independent and self-driven approach
• 5+ years' commercial experience working on back-end systems at high-scale startups
• at least a year of commercial experience working with Go
• strong knowledge of security practices, ideally with a slightly grey-hat background
• a working knowledge of the entire web stack - from how DNS lookups are transmitted, to how browsers prioritize CSS rules
• awareness of compliance and financial regulation

We are a small team so it is important that the successful candidate is not only technically highly competent, but also a great cultural fit!

Perks & Benefits

As well as a competitive salary (£60-75k, dependent on experience) and equity based remuneration, benefits of working at Cuvva include working in our new offices in Shoreditch and of course significant savings on your car insurance.
