Relational data is stored in Postgres and other types of data are held in other non-relational data-stores such as etcd and Kafka. All services are containerized and deployed to kubernetes. Our frontend client is implemented in Angular 7 (Typescript).

Our development process is lightweight Scrum with 2 week iterations. Code is contributed to projects via merge/pull requests which are peer reviewed by colleagues. Code is continuously integrated, tested and checked with automated CI pipelines.

As a team we value shared ownership of our code, design simplicity, code cleanliness and continuous improvement of products and processes.

Job Description:

You would be joining our cross-functional team to help us develop our customer-facing web application.

As a full-stack developer you would be responsible for implementing new features across multiple levels of our stack, assisting with the maintenance of our existing codebase/infrastructure and contributing to our overall development workflow.

The ideal candidate would be enthusiastic in helping us improve our engineering culture and quality, bringing new ideas to the table and helping us achieve clean, maintainable code and architecture.

The following skills represent the perfect skill-set of a candidate but we understand very few developers fit this profile exactly. As such, we would welcome candidates that can bring deeper knowledge of a subset of our requirements to our team, even if they have limited experience in other areas.

Desirable Skills:

  • Comfortable designing and developing GRPC/HTTP APIs with Go
  • Experience in at least one modern front-end framework, preferably Angular (2+) with Typescript
  • Knowledge of standard web development technologies including HTTP, CSS/SCSS, ECMAScript, HTML, bundling and testing tools
  • Experience containerizing and orchestrating infrastructure with tools such as Docker and Kubernetes
  • Interest in working with relational databases such as Postgres or MySQL
  • Previous exposure to non-relational data infrastructure including queues (Kafka), indexes (Elasticsearch) and key/value stores (etcd) would be desirable but not required
  • Business fluent in spoken and written English

What we offer:

  • Hands-­on experience in building a product that’s revolutionizing the payment security industry
  • Technical challenges to solve with a real world application
  • An environment open to adopting new technology and ideas

Job Description

About Fraugster:

Fraugster is a payment security company with the goal of eliminating fraud and increasing our customers’ profits. Over the last years we’ve invented an artificial intelligence technology that combines human-like accuracy with machine scalability. This ability lets us foresee fraudulent attacks before they actually happen and gives us a distinct competitive advantage over every other player in the payment security space.

We’re already working with some of the most well-known payment and e-commerce companies in the world. Notable clients include companies like Ingenico and SIX Payments. Fraugster is backed by top-tier investors and is currently managing billions of Euros for its clients.

The team is responsible for simplifying the process of building data and metrics-driven products and features. This is a high impact, high visibility role that directly affects the experiences of all our engineers.

The experience we are looking for:

  • Designing, implementing and debugging large-scale data infrastructure systems, and identifying their performance bottlenecks
  • Understanding of long-term impacts of key design decisions and handling failure scenarios

  • Monitoring and operating open source software in production at scale e.g. Kafka, Kubernetes, Docker
  • Operating telemetry tools, e.g. the ELK stack, Prometheus, Grafana, Jaeger, Istio and others

Senior Software Engineer with Luno
London, United Kingdom£80k - £100k
2 years ago

Job Description

Luno is a leading global cryptocurrency company operating across more than 40 countries and with offices in London, Singapore and Cape Town. We’re a profitable, growing company with over 2 million customers, and are backed by some of the top tech investors in the world.

Our products and services make it safe and easy for people and businesses to buy, store and learn about cryptocurrencies like Bitcoin and Ethereum. Our vision is to upgrade the world to a better financial system.

To the moon! 🚀

Your Mission

We have multiple openings for senior software engineers in our brand new London office. These are in a range of teams including fraud, platform, payments, shield, onboarding, and crypto-security. With over 40 engineers based in our Cape Town office, you’ll be joining a group of highly motivated experienced developers who you’ll work collaboratively with across our currency exchange, fraud, payments and compliance pods.

As a small company operating on a global scale, you’ll immediately see how your contributions directly impact both our internal users and client experience. We make decisions based on facts, not fiction. Many of the problems we’re solving result in genuinely trail blazing solutions which can’t be found on StackOverflow; so we’re looking for an experienced engineer that thrives on working in a complex domain.

We use Go, microservices architecture (gRPC) and AWS, but if you come from a Java, Python or other relevant language we’ll help you get up to speed with our comprehensive engineering onboarding program.

How we work

We succeed as a team. Our teams are split into pods, each of which focuses on a specific aspect of our product. Any engineer is able to deploy to production, and we deploy multiple times each day. Your pod will include a product owner, back end engineers, Android and iOS developers, and web developers who each bring a unique perspective to the problem you’re all solving.

A typical day

  • Join the pod’s daily standup to share progress and remove blockers
  • Collaborate with other engineers on the design of a new payment integration to launch to a new market
  • Write clean, well-tested code that directly affects users, the company and the Bitcoin ecosystem
  • Grab lunch with the company (we provide lunch Monday - Thursday)
  • Coach a team member by giving feedback on their pull-request

What’s in it for you

This is a fantastic opportunity to learn more about cryptocurrencies, blockchain, emerging and developed markets, and scaling a global business. We provide great benefits and the autonomy to conceive and execute your own projects. Best of all you get to work with a diverse team of talented, ambitious and friendly people on something that will truly revolutionise the world.

As a “Newnaut” we’ll fly you to Cape Town to meet the wider team, and go through our comprehensive onboarding program. We expect you to have a passion for blockchain and cryptocurrencies but we understand that this is a new industry so we’ll help you learn about how the blockchain works and understand all aspects of our business.

What you’ll need

Building a new financial system for the world requires a special breed of people working together with unusual skill, focus and determination. “Moontality” represents the ten core principles that underpin everything we do, setting us apart from the rest.

As an experienced lead-level or senior engineer, you’ll have:

  • A solid foundation in computer science in areas such as algorithms, data structures, and software design
  • Extensive programming experience in an object-oriented language. We use Go but we welcome applicants who have strong experience in other languages like Java, Scala or C++, etc.
  • Proven experience of building, shipping and supporting a product
  • An interest in cryptocurrencies like Bitcoin

Don’t be put off if you don’t tick all of the boxes – they’re a guide based on what we’d love to see but we appreciate that great software engineers have diverse backgrounds.

Cabify Logo
Senior Fintech Core Backend Developer (Go) with Cabify
Madrid, Spain€30k - €70k
1 year ago

Job Description

Lana is a new project born out of Cabify’s and Maxi Mobility’s New Business department. The aim is to create an alternative banking platform optimised to empower “gig economy” workers to get paid more quickly, reliably, for saving and making payments. Lana is a small, dedicated, and highly skilled team focussed on building an awesome product with the potential to grow into a company that changes the lives of millions of people in Latin America who don’t currently have access to electronic banking.

The New Business department and Lana are very closely joined with Cabify and Easy Taxi teams with the aim of adding value and investigating business areas that are directly or indirectly related to the core products.

If we’re going to turn our vision into a reality, we’re going to need plenty more bright, ambitious people to join us!

About the position:

As a senior engineer in the Lana Core Team, you will be working to solve complex problems in the services that empower the rest of the company to run. You’ll be actively working with the CTO and other areas of the business so you can determine the direction development should move in.

Lana strives for a modular working environment where each module determines its own development pipeline, according to the general direction of the company and requirements of the customers.

Our current backend tech stack for this project consists of:

  • Go
  • Docker + Kubernetes
  • CouchDB
  • CockroachDB

We are looking for someone with previous experience working with Go (desirable), however if not we are still happy to consider your application. We believe that even if you have worked in Java or C# all your life you can still pick up Go pretty quickly. For us it is more important to have someone who is adaptable and can pick up languages quickly.

Security is a major concern for this project, so decisions on how best to isolate, restrict, and monitor access to services and solutions will be a big challenge.

What we’re looking for:

We’re searching for engineers with a solid understanding of how to deal with building secure, reliable, and scaleable solutions. Your objective will be to build upon the existing core services to ensure that the other areas of the company can also develop solutions in their problem domains.

This is a hands-on role in a new project within the group, so it’s a great opportunity to make your mark from the very beginning. Your decisions will affect how the company moves in the future.

We’ll be looking for most of the following in your profile:

  • Strong educational background, e.g Degree in Computer Science, Physics, Engineering, Mathematics, or equivalent
  • Ability to communicate with the team in English (written and spoken)
  • Unix/Linux systems knowledge
  • A background in security and a deep understanding of the potential risks.
  • Fintech, Payments, and PCI experience very highly valued.
  • Real-time distributed systems deployment.
  • A preference for simple system architectures and micro-services, including experience in technologies like Docker.
  • Advanced networking knowledge.
  • Ability to work autonomously in an unstructured environment.
  • Passion for writing simple, clean and efficient code and/or solutions.
  • Comfortable with complex git/github workflows (submodules, branches, forks, pull requests, merging, rebasing)

The good stuff:

As part of the Maxi Mobility group, which includes Cabify, we’re a company full of happy, motivated people and we never want that to change. Here are some more reasons why it rocks to be part of our family.

  • Flexible work environment & hours
  • Regular fun team events
  • Cabify staff discount
  • Personal development programmes
  • All the gear you need - just bring yourself.
