Job description

ABOUT US

We are building a future where every student on the planet can access, enjoy, and benefit from the highest quality education. Since founding Knowunity straight out of high school in 2020, we've been committed to revolutionising how students learn.

Millions of students already use our AI learning companion weekly. We just raised €27m from strong Investors - one of Europe’s largest education rounds in the past years. The AI learning market is at an inflection point, finally enabling true personalisation at scale, and we're determined to build the first AI learning unicorn in this space.

You will join a truly driven team of 60 hands-on builders serving 1 billion students worldwide. If we execute on our product vision, you will have built something that transforms education globally.

This is your chance to be part of building a generational company.

Your mission

The problem you’ll solve: You’ll support our fast-moving engineering team in building and improving the product that helps millions of students learn better every day.

Your ownership:

  • Support product managers and engineers in building new product features and improvements.

  • Help implement core functionalities that directly impact our user experience.

  • Improve code quality and contribute to our technical foundation as we scale.

Why this matters: Knowunity is used by millions of students globally, and we’re just getting started. The features and improvements you help build will directly impact how students learn and grow with us every day. Your work helps us move faster and smarter on our mission to become the #1 learning companion for 1 billion students.

What success looks like: You contribute meaningfully to live product features, collaborate closely with senior engineers and the CTO, and develop rapidly as a technical talent. You bring your ideas to the table, take ownership of mini-projects, and leave the internship with the opportunity to join full-time.

Your story

Your mindset
You’re the type of person who:

  • Builds to learn and learns by building - you love turning ideas into working products and figuring things out along the way

  • Thinks like a founder - you’re proactive, curious, and unafraid to take ownership in a fast-moving environment

  • Sees the full picture - whether it’s frontend, backend, or anything in between, you’re eager to contribute across the stack

  • Cares about users - you’re not just writing code, you’re solving real problems for real people

  • Leverages AI - as a force multiplier in everything you do

  • Values excellence over comfort - mediocrity isn’t in your vocabulary


Your track record
You’re currently studying (or have just finished) Computer Science, Software Engineering, or a related field. You’ve built things you’re proud of — whether in class, side projects, or internships — and you’re hungry to apply what you know in a real-world, high-impact setting. You want to grow fast, contribute meaningfully, and help shape the future of a product users love.

Must-haves

  • Currently pursuing or recently completed a degree in Computer Science, Software Engineering, or similar

  • Strong programming skills across backend and frontend

  • Fluent English; German is a plus

  • Ready to work from our Berlin office 5 days/week (with some flexibility!)

What we offer

Not for everyone, everything for the right ones.

  • Competitive compensation and equity: We’re are building Knowunity to dominate the global AI learning market. Your compensation package includes competitive salary paired with meaningful equity in a company with genuine unicorn potential. Team members who help us reach that goal will be rewarded accordingly.

  • Elite team and true ownership: You’ll work alongside 60 exceptional people who match your ambition within a flat hierarchy - direct access to founders and leadership without bureaucratic middle layers. You'll own entire areas from conception to delivery with real decision-making authority.

  • Meaningful impact at scale: Your work will have immediate, measurable impact on education globally and directly improves how millions of students learn.

  • Benefits: 20 days annual leave +1 extra day per year with Knowunity, 40 days work from anywhere, personal development budget, mental health support via Nilo, Urban Sports Club, monthly become1 retail vouchers, team and company events


We’re not here to coast - we are building something exceptional. We’re a lean team of ambitious people who push hard, move fast, and constantly raise the bar. The real perk is not standard benefits - it’s joining 60 amazing people who challenge you to level up daily. If you’re hungry, thrive under pressure and ready to go the extra mile, this is where you will accelerate your career faster than anywhere else.
