CTO & Technical Visionary

Salary Competitive

Equity To be negotiated

20 hours/week

Are you a technical architect with an entrepreneurial spirit? Do you want to lead a platform that is transforming professional upskilling?

At Spuddle, we have evolved from a community of ~200,000 followers to building Duolingo for Microsoft Excel. Our mission is to eliminate "spuddling" (inefficiency at work) using gamified, interactive microlearning learning. We are looking for the right person to bring our MVP across the finish line, and continue building beyond it.

Compensation & Equity

We begin with project-based (milestone-based) pay. However, for the right profile, the goal is a long-term role with the opportunity for a significant equity stake within 12 months.

Your Role

Your primary task is to bring our mobile app safely to market on iOS and Android. You will become the technical lead for our current front-end team and take full responsibility for our backend and deployment.

Our technical foundation (which you will further develop):

Backend: Monolithic TypeScript service running on Bun and Hono.
Database: PostgreSQL with Drizzle ORM.
Frontend: React Native & Expo (with Tanstack Query & Zustand).
Infrastructure: Google Cloud/Azure, Terraform/OpenTofu, and Expo Application Services (EAS).

We are a startup. That means short decision-making paths, the freedom to experiment, and the opportunity to build a team from the ground up, eventually leading an entire tech department as we raise further capital and scale. And you aren’t just an employee; you are the architect of our technical foundation. You define the direction for the stack, infrastructure, and culture.

Who are you?

You thrive with deep coding and leadership. You love mentoring other developers and setting a high bar for code quality. You understand the unique challenges of global scaling, and you know when to build perfect monitoring versus when to focus 100% on user-facing features. Finally, you have hands-on experience with the entire app release flow.

How to Apply

We are looking for the right person, not just the right CV. To be considered for the position, please send us:

Your CV
A brief cover letter (6-10 lines) explaining why you are passionate about building Spuddle and how your technical background makes you the right person to take us to market.

We look forward to getting to know you! 🙂

Spuddle is developing a Duolingo-style app for Excel to help young professionals boost their digital confidence and career readiness by turning complex skills into fun, bite-sized learning. Our secret sauce? Gamification, microlearning, and a community-driven approach that makes Excel something you actually want to practice. Across the world, more than a billion people use Excel and yet most have never been taught how to use it properly. For young professionals and recent graduates, this creates a huge barrier: they’re expected to “just know” Excel, but in reality many feel insecure, waste time on manual tasks, or miss out on opportunities because of weak digital skills. This gap affects productivity, confidence, and employability and it’s widespread across industries, especially in early career roles where Excel is a daily tool. We’re building a mobile app that makes learning Excel engaging and accessible, like Duolingo, but for spreadsheets. Instead of long, boring tutorials, users complete short, gamified exercises that fit into their everyday routines. The app adapts to their level, rewards progress, and helps them practice consistently until Excel becomes second nature. Beyond Excel, our vision is to expand into other workplace tools, becoming the go-to microlearning platform for digital skills. Spuddle started as a side project on social media. We shared quick Excel tips on Instagram and TikTok, and within six months had over 200,000 followers. The overwhelming response showed us just how many young professionals struggle with these skills and how much they crave accessible, fun learning. What began as a hobby quickly grew into a mission: to make digital skills education less intimidating and more empowering. We’re building Spuddle because we’ve lived the problem ourselves, and we believe mastering the basics should feel motivating, not overwhelming.
