Staff Platform Software Engineer

⚡️Can you imagine shopping online in a simple way, always getting the best price without wasting time comparing options? That's exactly what the team at Joko is building: a new gateway to smarter shopping.

Some engineers build features. Others build the tools, processes, and systems that enable dozens of engineers to build better, faster, and with fewer headaches.

If you're one of the latter, keep reading...

Joko is looking for people who will lead the evolution of its internal platform, improving reliability, scalability, and the developer experience across the entire engineering team as the company continues to scale globally.

Before we dive into the juicy bits… some context

Joko was born in Xavier’s living room — but not just any living room. That room saw the birth of an idea that would change the way we shop online forever. Three friends — Xavier, Alexandre, and Nicolas — joined forces in 2018 with one obsession: to make shopping easy, efficient, and way less painful than bouncing from one website to another.

And they didn’t come empty-handed. Xavier had been leading a travel portal at Jumia (the biggest e-commerce platform in Africa), Alexandre was building scalable tech at Criteo, and Nicolas brought experience from exigents sectors like banking. These weren’t their first spells.

After years in e-commerce, they realized online shopping was still clunkier than a Thanksgiving dinner with the Roy family from Succession. So, they set out to create a platform that helps people make smarter buying decisions, save some serious cash, and do it all powered by tech and data.

Here's how Xavier, CEO and co-founder, tells it himself

Today, Joko is a certified B Corp helping over 6 million users save money at more than 7,000 stores. And they’re just getting started. They’re expanding fast in the US, and their next big quest is building an AI-powered shopping assistant that knows what you want… before you even finish your sentence.

Joko products not only offer automatic cashback but also automatic coupons, price drop alerts, carbon footprint tracking, and even a buy now, pay later system.

And now? They’re building a shopping assistant powered by AI — it understands your needs before you say them out loud, recommends products with real intelligence, and helps you save money without breaking a sweat.

But what we really love about Joko — and we say this with a full heart and full mouth — is the way they work: radical transparency, open access to information (yes, even board presentations), real trust in the team, and a principle we adore: “Culture is the product we build for our people.”

Don’t just take our word for it 😉 — check out their vision on tech and product and see for yourself.

So… what will I be doing day-to-day?

You'll join a team that is building the Platform Engineering function at Joko from the ground up. Until now, every engineer has been responsible for their own deployments, monitoring, and infrastructure. Your mission will be to bring focus, expertise, and vision to everything that enables the rest of the engineering organization to move faster, with greater confidence and less friction.

Working on a serverless AWS infrastructure, you'll help improve scalability, resilience, and cost efficiency across the platform. A big part of the role involves designing solutions that make it easier to deploy, test, and operate software in production, as well as building internal tools that enhance the developer experience and raise the bar for observability, security, and release quality.

Beyond the platform itself, you'll have the opportunity to explore how AI can multiply team productivity through automation, agents, and internal tooling. This isn't a role for someone who prefers defining architectures from a distance. It's for a hands-on engineer who enjoys identifying problems, proposing improvements, and driving them through to implementation from end to end.

• Build the platform that powers engineering: As one of the first dedicated Platform Engineers at Joko, you'll help create the tools, processes, and standards that enable teams to move faster and with less friction.
• Scale infrastructure without losing control: You'll improve the resilience, capacity, and efficiency of our systems to support millions of interactions while maintaining a reliable experience for both users and engineers.
• Make problems visible before they happen: You'll evolve our observability, monitoring, and alerting strategy, helping teams detect incidents early and resolve them quickly.
• Turn efficiency into a competitive advantage: You'll identify opportunities to optimize costs, simplify architectures, and make technical decisions that have a direct impact on the business.
• Raise the bar on security pragmatically: You'll work on permissions, access management, secrets handling, and engineering best practices to ensure security becomes a natural part of how software is built.
• Improve the developer experience: You'll drive improvements across CI/CD, testing, environments, and internal tooling so that shipping changes becomes increasingly simple, safe, and reliable.
• Multiply productivity through AI and automation: You'll build internal tools, automations, and AI-powered solutions that help teams eliminate repetitive work and focus on creating value.
• Lead cross-functional technical initiatives: You'll collaborate with engineering, product, and business teams to identify opportunities, drive meaningful improvements, and raise the technical bar across the organization.

Just like no two classes at Hogwarts are the same, no two days at Joko look alike either. The team works in task forces — cross-functional squads formed around the company’s quarterly priorities. No rigid sprints, no endless meetings — just focus on what really moves the needle. Tasks are prioritized by Product, and you’ll have the autonomy to pick the next project, bring logic, creativity, and collaboration to the table, and drive it to completion.

You'll work closely with the Internal Needs team, an initiative focused on professionalizing everything related to platform engineering, infrastructure, observability, security, and developer experience. You'll have the autonomy to identify problems, propose improvements, and lead initiatives that help engineering teams work more effectively.

The infrastructure is primarily built on AWS, using a serverless architecture powered by services such as Lambda, DynamoDB, SQS, and S3. Rather than developing end-user product features, your mission will be to build and evolve the platform that enables those features to reach production quickly, safely, and reliably.

Platform Engineering at Joko isn't a team operating in isolation. You'll collaborate closely with software engineers, product managers, and business stakeholders to understand bottlenecks, improve the developer experience, optimize costs, strengthen security, and increase system reliability.

You'll also play an important role in the evolution of internal tooling. From automation and CI/CD improvements to new AI-powered solutions, the goal is to remove friction and significantly increase the execution capacity of engineering teams.

And if you think this role is only about infrastructure → think again 🙂‍↔️. Communication carries a lot of weight at Joko. They're looking for people who can connect technical decisions to real product, business, and developer experience outcomes. Because building a great platform isn't just about deploying technology—it's about helping everyone else do their best work.

💚 ProBono time — 1 day per quarter for volunteering during working hours

This position is 100% remote from Spain, although priority is being given to profiles located in Barcelona or Madrid or Valencia.

The important thing is that you live in a well-connected location (hence our priority in Barcelona or Madrid), because there will occasionally be meetings or events in Paris or Barcelona, and they'd like you to be able to escape without having to tame logistical dragons.

However, if you live in Barcelona, you'll be closer to the Urquinaona coworking space and can stop by whenever you want: to meet people, share ideas, or simply pick up some branded pens.

Joko doesn’t believe in clocking in, or in forcing early wake-up calls just for show. Here, everyone manages their own schedule in the way that works best for them — because when you're treated like an adult, you act like one. There are no fixed hours or daily meetings that could’ve been a sticky note: just syncs every other day, focused time for deep work, and actual breathing room to think.

You can even work remotely from abroad for up to 3 months a year if you feel like switching up the view (and the time zone). Just make sure you’ve got a solid internet connection, a good mood, and the drive to make an impact. The rest… you build it your way.

Never alone...because you are not going to be the only manfredite inside!

You'll join Joko’s Engineering team — a crew of senior engineers with rock-solid and diverse backgrounds, from ex-Google and other big corps folks to PhDs in Machine Learning. It’s a team that builds with brainpower, curiosity, and real camaraderie — not just lines of code.

You’ll work closely with one of the Engineering Managers, the VP of engineering, who not only steers part of the technical ship but knows what it means to build product from scratch. And you’ll also have a direct line to Alexandre, co-founder and CTO, who’s still deeply involved in Joko’s tech strategy.

Even though the team is spread across Paris, Barcelona, and other corners of Europe, collaboration runs so deep you’ll feel like they’re sitting right next to you — minus the awkward lunchbox negotiations.
