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: 

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)

What you will own:

At ZEPZ, the parent company of WorldRemit and Sendwave, our mission is to empower migrant communities worldwide by making international payments fair, fast, and flexible. The Payments Domain is the strategic core of this mission, serving as the end-to-end backbone for millions of remittance flows across both our global brands. This is where your engineering skills will directly impact lives, managing every critical step from mobile app interactions and pay-in/payout processes to robust backend and safeguarding operations.  

As a Senior Software Engineer in this domain, you will not just maintain, but architect and expand our offerings, contributing to the development of new products that redefine cross-border finance. You will be instrumental in building and extending cutting-edge APIs (GraphQL, gRPC), driving significant operational efficiency by automating complex processes using our Business Process Management platform, and integrating pivotal external partners into our global flow. Beyond core development, you will innovate by crafting internal tooling that directly empowers our Operations team to deliver best-in-class customer support. 

We thrive on rapid iteration, operating in short, one or two-week sprints, where tasks are meticulously defined to support an efficient build-test-release cycle. Our teams embrace full ownership of solutions from concept to production, encompassing new feature development, implementing robust monitoring and alerting systems, and integrating with advanced security platforms for proactive threat detection.  

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.
