Job Description

Join Zepz: Breaking Down Borders, Together

Our Meaningful Mission

At Zepz, we're all about breaking down barriers for our customers and our teammates. Our purpose is deeply personal, we provide a lifeline and deliver opportunities to cross-border communities that need it most through cutting edge finance and tech.

Zepz is the power behind WorldRemit and Sendwave, driven by the mission to celebrate the incredible impact migrants have, both at home and abroad. We're not just moving money; we're building a world that truly recognizes and supports global connections.

Who You'll Be Joining

We look for mission-driven builders who thrive in a fast-paced environment connected to a true purpose. We’re an always developing team of experts that enjoy problem solving and bring clarity to tough challenges. At Zepz, we are Relentless Learners, always seeking feedback, and Responsible Owners, treating company resources like your own. We depend on Transparent Communicators who keep the team aligned through open, honest talk.

Our Core Commitments — What We Live By

Our vibrant and truly diverse culture is built on three core commitments, that guide how we work and interact:

• Integrity: We always do the right thing. It’s simple, but it’s the foundation of everything we build for our customers and each other.

• Outcomes: We work for our customers. Their success and prosperity are the results we focus on delivering.

• Velocity: We are fast! We maintain high energy levels and make smart decisions quickly, keeping us nimble and ahead of the curve.

Perks of Joining Our Team

We believe in empowering colleagues because we genuinely trust our team. Our culture is founded on this high trust, which naturally encourages the high ownership that drives us to meet our shared high expectations and deliver high performance. While we have all the tools to work remotely, we value the purpose and benefits of in-person connections so we expect our teams to come to the office on a regular basis, and therefore be within a comfortable commutable distance from our London office. Alongside a great office environment, think unlimited annual leave , great healthcare benefits, and employee discounts. We want you to thrive and focus entirely on making your biggest impact! In turn, we expect you to bring high ownership and commitment to your work. This is a place where we value trust and high performance, and we'll provide the environment and support needed for you to excel.

What You Bring to the Table

You are a technical architect with a builder’s mindset. You don’t just write code; you engineer solutions that bridge the gap between complex FinTech infrastructure and high-impact Marketing goals.

Your Technical Toolkit

• Backend Skills: You have extensive experience building scalable backend services. You are proficient in Java, Kotlin, or TypeScript.

• The Modern Stack: You’re at home with Spring, Python, NodeJS, and ReactNative.

• Cloud & DevOps: You’re familiar with the "how" of deployment—AWS, Kubernetes (EKS), Terraform, GitHub Actions, and ArgoCD are all part of your repertoire.

• Observability: You use the Grafana LGTM stack to hunt down faults and ensure system health before they become issues.

• AI-Ready: You are comfortable integrating AI tools within a safe, structured development environment to boost velocity.

Your Execution Style

• Quality over Quick-Fixes: You take pride in clean, readable, and well-tested code. You’d rather refactor a design for long-term health than patch a recurring problem.

• Collaborative Leadership: You can translate "marketing-speak" into technical requirements. You enjoy owning large projects, influencing the roadmap, and mentoring peers through code reviews.

• Customer Obsessed: You are a "get it done" person. You value shipping features that improve the user experience over chasing abstract perfection. If a flow doesn't work for the user, you’re happy to scrap the code and try again.

Bonus Points (The "Nice to Haves")

• You’ve previously worked within a MarTech or Marketing Engineering team.

• You have experience navigating the fast-paced, high-growth environment of a FinTech startup or scale-up.

AI Literacy & Tools

As Zepz continues to build AI into how we work, we expect everyone to engage with it as a core part of their role. For this position we are looking for:

• A genuine curiosity about AI and how it can be applied in your area of work — from accelerating analysis and insight generation, to improving how we design and deliver processes and communications.
• Practical experience using AI tools in a professional context — whether to connect information, draft content, build frameworks, or create insights from data. We want people who actively use AI to increase productivity, not those who are waiting to be told to.
• Strong AI literacy — an understanding of what AI assistants can and cannot do, how to prompt effectively, and how to critically evaluate AI-generated output before using it.
• Awareness of the ethical considerations and responsible use of AI in the workplace, particularly in the context of sensitive data, customer experience, and compliance.
• Prior experience using Claude (Anthropic) is a nice-to-have but not essential — what matters most is that you are genuinely engaged with AI as a tool, comfortable experimenting, and eager to share what works with your wider team.

If you want to join us in our journey to help break barriers in financial access and improve lives globally, there's no better place or time to join.

Our global team of 800+ people is spread across six continents. We aspire to hire the best mix of people from former Olympians to YouTube influencers and we speak over twenty languages. This incredible diversity isn't a bonus; it's the engine that lets us serve the world.
