Senior Scala Engineer
Posted: Jun 11, 2020
**Senior Scala Engineer** **Ready to shape tomorrow?** This is somewhere where innovative thinking and the power of technology know no limits. We know that the success of the business depends on the people who keep it moving, which is why we are looking for exceptional talent to join our international payments revolution. We’re bringing simplicity, transparency & scale to cross-border payments - a $120 trillion market. **About the role** Our software engineers are responsible for implementing an industry-leading API that has already processed over $50 billion of cross-border transactions for over 5 million end users, and is available to our clients 24/7. But we’re not stopping there, and our engineers are at the forefront of taking us forward to meet the demands of even greater scale. From our monolithic datacenter beginnings we’ve moved wholesale to AWS where our system runs as a set of distributed applications. We’re currently in the process of migrating those applications over to Kubernetes and Jenkins-X as we further embrace a microservices architecture. As a Senior Software Engineer you’ll play a key role within your team; taking responsibility for your services and the technology within them, but also in helping develop your team and its relationship with your product owner and the broader business. Teams are aligned to services and you’ll have: - clear ownership of your domain - a clean modern codebase - an independent path to production - strong platform and product support - the ability to make real changes with real business value. Our microservices architecture enables us to explore new languages and technologies in parallel with our existing system. The core of our system has been built using Ruby, leveraging backing services like RabbitMQ, Redis, and MySQL/Aurora, but we are keen to bring in engineers with more diverse backgrounds, and help us take Currencycloud to the next level of scale. **What to expect** You will be joining the Payments team at CurrencyCloud, where we are creating software to trade currencies that unlocks unique capabilities previously not available to our customers. The nature of the always moving markets requires creating highly-scalable distributed systems. We are looking for a person who wants to build new software in Scala, and is comfortable with reading other languages – ideally Ruby as a significant part of the backend software in the company is written in Ruby. We use various technologies for handling our data, primarily: RabbitMQ, Redis and MySQL. **The Details** - Day-to-day you’ll work with a variety of tools, technologies, capabilities and processes. - Distributed systems help to achieve scalability, improve availability and run our software in cloud-native environments on Kubernetes. - Cloud-related tools and services support these applications, such as Docker, Kubernetes, - ElasticSearch, log management systems, and Datadog APM, to name but a few. - API specifications, conforming to the OpenAPI (Swagger) standard, provide a clean boundary both externally between our customers and our product, and internally between our microservices. - Programming languages, you should be comfortable with functional programming in Scala and have experience working with other programming paradigms. There is also some Ruby, Java & Elixir in our code base. Other important stack related tools are cats/cats-effect, doobie, http4s, circe, ZIO & Tagless final. - SQL, and large SQL databases, provide the persistence layer for our applications. You’ll be working with (and know the limitations of using) such large datastores. Infrastructure automation is primarily owned by the infrastructure team, but you will be a consumer of their work, familiarity with AWS, Terraform, Kubernetes (K8s) and Docker is beneficial. - Testing approaches, including TDD, BDD and Contract Testing, all form an important part of our approach to quality assurance; ensuring that the code that we write forms products that are fit for use. Our QA engineers use Cucumber. - Agile development, with teams broadly aligned with the Spotify - Squads & Tribes - model, helps us deliver incremental improvements to our products in an iterative manner. Advocating this model, and joining us on a journey of continuous improvement, is a key attribute of senior members of our teams. - Continuous Integration and Continuous Delivery pipelines allow us to “automate all the things”, providing repeatable builds and consistent deployments. - GitHub, and the GitHub PR review process, forms a core part of our developer workflow, and peer reviews help share knowledge and improve quality. - Teamwork, and cross-team collaboration, is fundamental to the delivery of our applications. Whilst each application has an independent path to production, there will always be some activities and initiatives that span multiple teams and require cross-team collaboration. Within your team you’ll need to collaborate with a number of stakeholders, including Product Owners and QA, as part of your product development. None of these on their own are a must-have to apply for the role, but it would be useful to share with us any knowledge or experience that you have in these areas. I’m intrigued…what’s the interview process? - Quick chat with our internal tech recruiter (to make sure things like salary, location, general approaches to dev are aligned to how we work.) - Tech chat over a hangout with a Tech Lead or Senior Engineer (we want to have open discussions with you about how you approach coding and what you like from a team that you work with) - Normally we’d invite you to the office, but in Covid-19 times it will be all over video! We’ll talk about your experience, some coding approaches and you’ll also get a chance to talk with one of our - - Product Managers about how we all work together - Chat with our engineering manager - We’ll make you an offer - We’re colleagues! **Anything extra to add?** A comfortable no dress code policy & flexible work from home arrangements are provided for all our employees. We offer a comprehensive range of employee benefits which include 25 days paid leave, 5% pension, BUPA health insurance, life insurance, long term sickness protection, a day off for your birthday and socials every Friday. So, if you’re ready to join a thriving global business in the heart of London, get in touch for an informal discussion!
