The Team 👥

Team Size: You’ll be joining a group of 6-7 Senior Engineers, led by Lead Engineer. 

Daily Routine: UK teams have an optional daily sync/social meeting, with daily updates provided asynchronously via Slack. 

Responsibility: You’ll take ownership of the entire delivery process. This includes problem exploration, solution development, and collaborating across other functions (Product, Customer Operations, etc.) 

Workflow: We embrace flexible workflow, adapting to the needs of our projects and team members. Our approach is similar to Kanban. 

Estimates & Planning: Most work is customer facing, so clear communication of delivery dates is key to managing expectations. We aim to keep the process light and efficient. 

Customer support: You’ll support high-volume payment products for large financial institutions and banks, helping resolve queries and investigating transaction anomalies. While day-to-day interaction with customers is minimal (we have dedicated teams to handle customer communication), significant part of the work is driven by customer requests. We’re always seeking opportunities to optimise and automate this work.  

Type of work: The main challenge in front of the UK team is continuously improving the reliability, observability and performance of a mature, high-volume payments platform. This includes deep analysis of issues, designing and executing robust testing strategies, and a keen eye for noticing risk and inefficiencies with a drive to reduce them. 

Objectives: Expand Form3’s position in the UK market by onboarding customers and provide them with the best platform by exceeding reliability and availability SLAs.
