The role consists of working in a team that owns critical batch payment processing capabilities and is focused on maintaining high levels of reliability, resilience, and production stability.  

Looking ahead the team have an exciting pipeline. We’re onboarding several new customers while continuing to improve our automation and onboarding processes. A key milestone for us is delivering our largest customer to date in the UK. This will increase the volume and criticality of the payments we process and supporting services. We’ll also be working on observability, and SLOs, SLIs across our services and improving our testing posture, working on our product offering, and enhancing our DR testing across multi-cloud components. We have a responsibility to ensure our services are reliable and resilient opening the door to new initiatives as needed. You can look forward to plenty of interesting challenges to work on. 

WHAT YOU’LL BE DOING 🏗️ 

• Designing, building, and running cloud-native microservices in Go that are the backbone of our real-time payments platform 
• Building systems that are highly available, low-latency, and scalable, handling billions of payment requests with precision and resilience

All services are in Go apart from one of our reporting services so a bit of Java experience is a plus. The same goes for infrastructure as code and kubernetes experience . We have supporting platform teams but work within a devops culture. If you make it, you ship it. 

• Deep understanding of designing and building distributed systems 
• Enjoys working on complex challenges within critical software where high performance and robustness are essential 
• Familiarity with cloud and containerisation technologies, test automation tools and CI/CD pipelines 
• Interest in owning projects end-to-end and supporting them as they go live in production  
• Appreciation of clean code and software engineering best-practice  
• Experience with Go, along with a “right tool for the job” mentality  
• Great communication skills who enjoy sharing knowledge and collaborating with others

• Infrastructure: AWS, GCP, Azure, Kubernetes  
• Platform: CockroachDB, NATS JetStream, Elasticsearch, Vault, Cilium 
• Tools: Terraform, Flux, GitHub, Prometheus, Pact.io, Tilt 
• Code: Go (and a little Java), containerised microservices, CQRS, open source  
• Ways of working: TDD/BDD, Pair Programming, 100% remote, SecDevOps 

THE TEAM 👥 

As a small, focused team we value ownership, collaboration and continuous improvement. We start our week with our Headliners session, where we discuss our focus for the week ahead. This is followed by an optional coffee catch up each day to connect as a team / share any important team updates. We try to pair programme where we can, and will expect the candidate to be comfortable working in this way. 

We operate on a shared on-call rota, with a weekly shift covering both day and night, plus a separate weekend rotation which is offset from the weekday on-call. You would be expected to take part in this rotation once onboarded. 

INTERVIEW PROCESS ✍️  

Stage 1: Screening call with Talent Team 

Stage 2: Take home test 

Stage 3: Technical interview 

Stage 4: Team interview 

We always aim to stick to the above process, however there may be occasions when an additional interview stage is needed for us to be sure we find the best fit for the role!
