Junior AI Product Engineer (Full-Stack) Job

OptiMonk is an AI-powered conversion optimization platform that helps small and mid-sized online stores turn visitors into customers. We've been on the market for more than 10 years, we're the market leader in Hungary, and our software is used in 140 countries worldwide. We're a profitable SaaS company with a Debrecen office and a remote-friendly culture.

We are now looking for a Junior AI Product Engineer who doesn’t just enjoy coding, but also has a strong sense for business and naturally uses AI tools in their daily work. We are a profitable SaaS company with an office in Debrecen, operating in a remote-friendly setup. 🏠

💼What will be your mission?

You won't be ticking off tasks — you'll be solving problems. At OptiMonk, autonomy isn't an expectation, it's part of everyday life:

Direct impact: You’ll work directly with the CEO and CTO to understand real user problems and quickly validate solutions.
Shopify app development: You’ll build and improve a key Shopify app using modern AI tools.
AI-driven development: You’ll connect LLMs, APIs, and no-code/low-code workflows, and build internal tools, assistants, and prototypes that support development (you’ll learn innovative workflows that are extremely valuable).
End-to-end ownership: You’ll take smaller problems from idea through v1 development all the way to production, with senior support. You’ll measure results and iterate based on feedback.
Product & design focus: You won’t just write working code—you’ll collaborate with the Product team to ensure features are simple, fast, and impressive for users.

👀Who are we looking for?

1–2 years of hands-on development experience (show us what you’ve built).
Full-stack mindset: confident in modern JavaScript frontend frameworks (Vue or React) and backend environments (Node.js).
Database fundamentals: Comfortable working with MongoDB or other NoSQL solutions.
AI-native workflow: Tools like ChatGPT, Claude, Replit, GitHub Copilot, or Cursor are not “the future” for you—they are essential extensions of your daily work and side projects.
Business / entrepreneurial mindset: You care about product decisions and think about why a feature is valuable for users.
English: Most communication will be in Hungarian, but the product is in English and we have international colleagues, so you should be comfortable using English in user-facing and conversational contexts.

🌟What’s a plus?

Shopify: you’ve worked with or developed Shopify apps before.
Marketing: you’ve been involved in marketing-related projects.
PM skills: you’re interested in product management work and like bringing PM thinking into your processes.

🎁What do we offer?

Trust and freedom: We align on direction, then you get space to execute. Experiment, iterate, build.
Remote-friendly culture: Work from wherever you’re most effective, but if you prefer office life, our office is open to you.
Top-level mentorship: Learn directly from founders and tech leaders how a successful global SaaS product is built.
Growth: You’ll learn and experience things here that are usually only available in Silicon Valley-type environments. We run an internal AI Academy, you can try and use any AI tools, and yes—we even have a Head of AI Research on the team.
