The Mission (aka Why You Should Care)

At Zelo, we're building the future of SME financing - turning receivables into instant liquidity for millions of businesses across the UAE. No more 90-day payment cycles or banks saying "you're too small." Just pure financial freedom powered by code.

And here's where you come in...

The Role (aka Your Playground)

We're looking for a Full Stack Developer with a growth hacker's soul to join our Growth Hacking Squad. This isn't your typical "build features from a backlog" gig. This is about experimenting, breaking things (safely), learning fast, and turning wild ideas into production-ready solutions that move our key metrics.

You'll report to our Head of Engineering but work hand-in-hand with our CEO, COO, and Head of Product. Why? Because at our size, hierarchy is just a fancy word that slows things down. You'll have direct access to decision-makers and your ideas will ship to production faster than you can say "deploy to main."

What You'll Actually Do

Ship experiments, not just features. You'll be our mad scientist, running A/B tests that could increase conversion by 2% or 200%. We don't know until we try, and that's the fun part.
Build quick and dirty (then make it beautiful). Start with a proof of concept that validates the hypothesis. If it works, you'll architect it properly. If it doesn't, you've only wasted a day, not a month.
Become a data detective. Dive into our databases, pull insights that nobody asked for but everyone needs. "Hey team, did you know that companies who upload invoices on Tuesdays convert 3x better?" That's the kind of gold we're mining for.
Learn new tools like they're Pokemon cards. PowerBI today, Amplitude tomorrow, whatever helps us understand our users better. We'll pay for the courses, you bring the curiosity.
Turn successful POCs into production features. That hacky script that increased sign-ups by 50%? Time to make it scale to handle our next million users.
Be the bridge between "can we?" and "we did." Work across the entire stack - frontend, backend, databases, third-party integrations. If it touches our growth metrics, it's your domain.

The Tech Stack (aka Your Toolbox)

Core Languages: JavaScript/TypeScript (our bread and butter) Frontend: React, Next.js (but if you convince us Vue is better for a specific experiment, we're listening) Backend: Node.js, Express (with some Python scripts when needed) Databases: PostgreSQL, MongoDB, Redis (and yes, sometimes good old SQL queries that would make a DBA cry) Cloud: AWS (EC2, Lambda, S3 - the whole alphabet soup) The Fun Stuff: Segment, Mixpanel, Google Analytics, PowerBI, Metabase

But honestly? We care more about your ability to learn and adapt than your years with any specific tool. Built something cool with a different stack? Show us. We're more interested in how you think than what's on your resume.

The Human We're Looking For

You've got 3-5 years of experience, but more importantly, you've got stories. Stories about that time you stayed up all night because you were this close to cracking the problem. Stories about hacks that shouldn't have worked but did.
You think in experiments, not features. While others ask "What should we build?", you ask "What should we test?"
You're comfortable with ambiguity. We won't always have perfect specs. Sometimes it'll be "Hey, our activation rate sucks. Figure out why and fix it." And you'll love that challenge.
You can work independently but love to collaborate. You'll have the freedom to own your projects, but you'll also be jumping on calls with the CEO to brainstorm the next growth hack.
You're a builder at heart. Maybe you've got side projects. Maybe you've tried starting your own thing. Maybe you just can't help but automate everything in your life. We get it. We're the same.
You understand that done is better than perfect (but you also know when perfect is actually necessary).

Why Zelo? Why Now?

We're at that perfect stage. Not so early that we're just an idea, not so late that you're employee #5,000. We've found product-market fit, raised our Series A, and now we need builders who can help us scale from thousands to millions of users.
Your code will have an immediate impact. Ship on Tuesday, see the metrics move on Wednesday. No six-month release cycles here.
You'll learn more in one year than most do in five. Fintech, growth engineering, Middle East markets, startup scaling - it's a masterclass in building modern tech companies.
We're solving a real problem. This isn't another food delivery app. We're literally changing how SMEs survive and thrive. Your parents will actually understand (and be proud of) what you do.

The Interview Process (We Respect Your Time)

Quick online assessment - Complete our technical test at https://app.testgorilla.com/s/ddxagslu (45 mins)
Chat with our Head of Engineering (30 mins) - Tell us your story, we'll tell you ours
Technical discussion + live problem solving (90 mins) - No leetcode BS, real problems we're actually facing
Culture fit with CEO/COO (45 mins) - Make sure we vibe

Total time: ~4 hours across 2 weeks max. We move fast because the best talent doesn't wait around.

Ready to Join the Squad?

If you've read this far and your heart is beating a little faster, start with our quick technical assessment at https://app.testgorilla.com/s/ddxagslu, and we'll reach out to you.

That's it - nothing else required for now.

P.S. - Our Head of Engineering once shipped a feature during a team dinner because a customer needed it urgently. If that sounds like madness you'd enjoy, you belong here.

Zelo: Turning receivables into rocket fuel for SMEs. Join us, and let's build the future of finance together. 🚀
