• We act like owners - We are relentlessly delivering for our users and spending money thoughtfully.
• We embrace embarrassing honesty - We function best when we're open and honest with one another — especially about our challenges and doubts.
• We have a bias to action - We get to first outcomes quickly, iterate and learn.
• We strive to be better - We may make mistakes, but always learn from them.
• We are inclusive - to better reflect and serve our users.

How you’ll help us achieve it:

We believe strongly in building teams that can orient around a well-defined mission and are equipped to execute autonomously against that mission. We count on you to collaborate with your team to build and support our platform and products used by customers sending money transfers from 50+ countries into 150+ markets worldwide. We are looking for engineers with expertise in designing and architecting complex, distributed systems at scale, and the ability to lead strategic technical initiatives.

Our tech stack is varied at the moment. Embarrassing honesty - We are in the process of migrating some of our products off legacy stacks.

• Backend services: Java(SpringBoot and SpringCloud), Python (to a lesser extent)
• Public Cloud: AWS
• CI/CD tooling: CircleCI, ArgoCD, Jenkins
• IaC: Terraform
• API Gateway and Service Mesh Architecture

What you will own:

The ZEPZ Backoffice (ZBO) team is responsible for developing both Front-End and Back-End solutions to enhance Customer Care Key Performance Indicators (KPIs). In this role, you will interact with back-end systems across various domains via APIs to streamline processes for Customer Care Agents. You will be instrumental in building and extending APIs (GraphQL, gRPC), automating processes using Business Process Management (BPM) tools, AI Agents, and custom AWS solutions, and integrating UI components orchestrated by back-end code. We operate on short, one-week sprints, ensuring that tasks are well-defined, refined, and granular enough to support an efficient build-test-release cycle within this timeframe. As a team, we take full ownership of our solutions from design to operation, which includes developing new features as well as implementing robust monitoring, alerting, and integration with security platforms for effective threat alerting.

What you bring to the table:

• Experience in building Java and/or Kotlin solutions for scalable systems microservices systems.
• Good understanding of various APIs technologies and goals they fulfill (graphQL, gRPC)
• Java Spring working experience
• Ability to analyze and optimize system performance, identifying and addressing bottlenecks and architectural limitations.
• At least a working understanding of cloud infrastructure based on AWS.
• Experience in designing and implementing monitoring dashboards for system health and performance
• Comfortable building effective relationships with stakeholders outside of technology.
• Some experience with AI assisted coding (reviews, tests, comments) tools like Github Co-Pilot
• An open mind with respect to diversity and inclusivity. Our team (and customers) come from all over the world.

Bonus Points if you have:

• Experience with Python or React is a plus, as these technologies are utilized to a lesser extent and can be beneficial.
• Prior experience in building AI Agents.
• A strong eagerness to learn new technologies and skills while advancing mastery in Java/Kotlin microservices.
