We are looking for a Founding Engineer at FITS!

If you're a future founder or an engineer eager to make a meaningful impact at scale, this is one of the most exciting early-stage opportunities in the Middle East.

FITS is building the future of luxury fashion by combining world-class styling with cutting-edge AI. We're on a mission to transform the way people shop by creating the world’s most personalized, stylist-driven fashion experience — and positioning Saudi Arabia as a global leader in fashion and innovation.

This is an equity-only role to start with, ideal for someone who thrives in early-stage environments and wants to make a meaningful mark on a product and company. You'll have the freedom to take ownership of technical decisions, solve complex user and marketplace challenges, and help create a unique fashion experience for our users.

Tasks

As part of our founding team, you'll have a rare opportunity to:

• Own the technical vision and build core infrastructure from the ground up
• Shape the product that will define a new category in fashion-tech
• Move fast, dream big, and leave a legacy in one of the fastest-growing tech and fashion ecosystems in the world
• Take the lead in building and launching FITS’ platform using FullStack, creating a seamless and visually engaging experience for shoppers, stylists, and brands alike.
• Work closely with the founders and collaborate across product, design, and engineering to turn ideas into polished, user-centric features that reflect our brand and mission.
• Develop clean, reusable components to speed up development and ensure long-term performance and maintainability of the platform.
• Proactively identify and resolve bugs or performance issues, continuously improving platform speed, stability, and user experience as we scale.
• Keep a pulse on the latest developments, bringing fresh thinking and innovative solutions to the table.
• Help shape the platforms technical foundation, contributing to decisions around architecture, tooling, and best practices as we build out our stack.
• Pitch in wherever needed — whether that’s tech-related or operational — as part of the hustle and adaptability that comes with startup life.

Requirements

• Hands-on experience building E-Commerce platforms — ideally 2+ years, but we care more about what you’ve built and how you think.
• Strong grasp of Dart and confidence working with RESTful APIs, third-party packages, and various integrations.
• A solid eye for mobile UI/UX — you know how to turn wireframes into intuitive, responsive, and beautiful experiences.
• Comfortable using version control tools like Git and familiar with tools that keep projects running smoothly (e.g., Trello, Jira, Notion).
• You care deeply about user experience and the platforms performance, and you’re always looking for ways to improve load times, responsiveness, and usability.
• Start-up ready: you’re flexible, proactive, and thrive in fast-moving environments where priorities can shift quickly.
• Great communicator who enjoys working collaboratively with cross-functional teams.

Nice to Have (But Not Essential)

• Exposure to other mobile frameworks (like React Native) or a willingness to explore them when needed.
• Familiarity with backend tools like Firebase, AWS, or experience with CI/CD pipelines.
• Experience working on marketplace products — especially those that connect different user types.
• A portfolio or examples of Full Stack platforms you’ve built — personal or professional.
• Equity compensation based on experience.
• Salary and Bonus upon successful fundraising.

Why Join FITS?

• Be one of the very first hires in a business with the ambition (and potential) to become the go-to way people discover and shop fashion — a name that could one day become a verb.
• Work directly with experienced, passionate founders who are building something meaningful at the intersection of tech, style, and culture.
• Have a real say in shaping the product, the team, and the culture — your voice will matter from day one.
• Get in early with meaningful equity, and be part of a bonus structure tied to our first raise and overall success.
• If you're entrepreneurial, love solving tough problems, and want to build a product that helps real people connect with brands and stylists in a fresh, exciting way — we’d love to chat.

We're looking for a builder. A visionary. Someone who wants to help create the next Canva or Figma — but for fashion.

Let’s reinvent fashion together, from Riyadh to the world.

FITS is a fashion marketplace connecting stylists, clothing brands and shoppers to reinvent the online shopping journey. Our goal is to emulate the experience of having a personal stylist and easily shop looks that are stylist-approved.
