We are looking for a Senior Full-Stack Engineer to join our Credit Card team.

Our mission is to deliver a seamless, transparent and customer-friendly credit card experience — from application to approval and beyond.

You will play a key role in building scalable full-stack solutions that help customers access credit products with confidence and ease.

• WHAT YOU WILL BE DOING
• Work in a distributed environment with Type Script/Node. js services and a Type Script React-based UI, running on AWS.
• Ensure our services and user interfaces operate with high stability, reliability and observability, with traffic properly managed, monitored and tracked.
• Build intuitive, seamless and high-quality customer experiences across the credit card journey.
• Design and implement new features, improve existing systems and services and optimize business-critical performance, scalability and efficiency.
• Actively contribute ideas on how artificial intelligence can improve our systems, workflows and customer experience.
• Take an active role in your team’s decision-making processes, including goals, technical concepts, timelines, architecture and technology choices.
• Work closely with the Product Owner to plan, refine and continuously develop new features within the team’s domain.
• Be deeply involved in the end-to-end development, operation and maintenance of the team’s products, following our “you build it, you run it, you own it” philosophy, including Dev Ops responsibilities

YOUR PROFILE

• Expert level professional experience with Node. js and Type Script.
• Experience building, maintaining and supporting React. js applications.
• Experience scaling services to handle traffic spikes, including the use of caching strategies and optimization of My SQL queries.
• Experience working with event-driven architectures, including message-based communication and asynchronous processing using technologies such as AWS SQS and SNS.
• Expert level experience with AWS and containerized microservice infrastructures, ideally using Kubernetes and Terraform.
• Familiarity with the LGTM observability stack: Loki, Grafana, Tempo and Mimir/Prometheus.
• Proven experience driving cross-team and cross-functional technical projects.
• Experience applying an AI-first approach to the software development lifecycle, using AI-assisted tools and practices to improve development speed, code quality, testing, documentation and engineering productivity.
• Experience working with additional programming languages beyond Type Script/Java Script is a plus.
• A passion for engineering excellence, clear communication and knowledge sharing.
• A proactive mindset, strong sense of ownership and willingness to take responsibility in a collaborative environment.
• Experience working in agile environments, ideally in startup-like companies or scale-ups with flat hierarchies.
