## Job description

## JOB DESCRIPTION

In short: We're looking for a Software Engineer to join our foundation team with a focus on mobile. You don't need to have years of experience in platform engineering But, you do need to have shipped real production software, to care about how things are built, and to already be working with agentic coding tools every day.

We're building the #1 AI learning companion for 1 billion students. A future where every student on the planet can access, enjoy & 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 - Europe’s largest education round in the past three 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 an elite team of +60 hands-on builders serving 1 billion students worldwide. If we execute on our product vision, you will have built something generational that transforms education globally. This is your chance to build a generational company that shapes how an entire generation learns.

## WHAT MAKES THIS DIFFERENT

You build at the frontier of AI engineering. We’re building the foundation for agents to build fast and with high quality on our code base. This includes custom MCP servers, our background agent https://www.linkedin.com/posts/activity-7480631765024419840-qIze?utm_source=share&utm_medium=member_desktop&rcm=ACoAACBHY-8B3HDNAUsoepIaf7gjkPgt0FjbviQ platform, and end-to-end agentic loops. This is an open engineering problem, not a solved one, and you'll be shaping our answer to it.

Your work multiplies across 25+ engineers. A design system component you build gets used in a hundred screens. A CI pipeline you cut from 15 minutes to 2 gives the whole org back a day a week. Foundation is the highest-leverage place in our engineering org, and the leverage is measurable.

Millions of students use what you ship. Foundation isn't a team that only builds for other engineers. You'll also build features that land in front of millions of users.

Real ownership, early. We're a small team with a large surface. You'll own meaningful pieces of the app and the toolchain from your first months.

Craft is taken seriously. We care how the app feels: how a sheet animates, how a list scrolls under load, how a component behaves at the edges. If you've ever been quietly annoyed by four pixels, you'll fit in here.

## WHAT YOU'LL WORK ON

Mobile foundation. The core of our Flutter app: shared components, the design system, state management, performance, and the tooling around it. You'll extend it, keep it healthy, and make it obvious for product teams to use correctly.

Agentic and AI infrastructure. MCP servers, our background agent platform, evals and feedback loops, and the integration of agentic tooling into our day-to-day workflow. A research background isn't required; a serious interest in agents as an engineering discipline is.

Developer experience. CI/CD, release tooling, and the feedback loop between writing code and seeing it live. Much of this work starts by noticing the same friction three times and deciding to remove it.

Product features. Shipping user-facing work alongside platform work, both to move the product and to stay honest about what it's actually like to build on our foundation.

Reliability and maintenance. Keeping what exists dependable, so 25+ engineers can build on it without thinking about it.

## YOU WILL GROW AT KNOWUNITY BY

- Learning architecture by doing it. You'll make real design decisions on the app's core, with review and mentorship from engineers who have architected mobile apps at scale. You'll see those decisions tested by 25 engineers and millions of users within weeks.
- Becoming genuinely strong at agentic engineering. Almost nobody is an expert here yet. You'll be building the practice for a whole engineering org while the field is still being written.
- Widening past mobile. Foundation's scope covers Go services, infrastructure, and delivery. You'll be expected to have opinions beyond the app, and you'll have the room to develop them.
- Working close to the whole org. Platform work means talking to every team. You'll get an unusually complete picture of how a product organisation actually functions, faster than you would inside a single product team.
- Operating at real scale. Millions of users, 26 countries, and a codebase where "it works on my machine" isn't the finish line.

## WHAT WE'RE LOOKING FOR

Must haves

- A few years of production experience building mobile (we use Flutter and Dart) or web applications.
- Daily use of agentic coding tools (Claude Code, Codex, or similar) and opinions on where they work well, where they don't, and how to work around it.
- An eye for design. You notice when spacing is inconsistent, when an animation feels wrong, when a component is close but not right.
- Clear communication in English and a genuine preference for improving systems that slow other people down, whether or not your name ends up on a shipped feature.

Nice to haves

- Built mobile apps with Flutter
- Worked with Golang (or similar backend language)
- Anything you've built with agents, MCP, or evals.
