What We Should Tell You About The Company Filed is building the first AI tax preparer trusted by America’s accounting firms. This industry might seem boring—but it’s a $70B backbone of the economy that’s breaking under a talent shortage no one has solved. We’re fixing it—fast.
In just 9 months, we’ve hit strong product-market fit , are generating insanely fast-growing, ridiculously sticky revenue , and are backed by top-tier investors . We’re not a tool—we’re the missing workforce firms have been sounding the alarm for. We’re building the future with expanding our already 30 person team, with those who want to say “I was there when it all started.” https://techcrunch.com/2025/05/21/filed-raises-17m-to-automate-the-drudgery-of-tax-prep/

What We Should Tell You About The Role We’re looking for a full-stack engineer who moves fast and thrives in high-velocity environments. You’re the kind of person who sees a broken workflow, understands the root cause quickly, and ships a fix in hours—not weeks. You love turning ambiguity into working software, and you don’t wait around for perfect specs to start building.
You’re a generalist who’s just as comfortable spinning up a backend service as you are crafting a clean, responsive UI. You sweat the details, but never let them block progress. You think in terms of speed, value, and iteration—always asking: how can we get this in front of users faster?
As one of our earliest engineers, you’ll help shape the core product and infrastructure. You’ll work closely with design, ML, and actual tax pros to reinvent how this industry works—by shipping fast, learning fast, and doing what others said couldn’t be done.
Our product and engineering team is based in Stockholm . We’re prioritising local candidates, but will consider candidates from elsewhere in the EU, who can travel to Stockholm. ⸻

Growth And Levels We operate on six levels, from Level 1 to Level 6. Each reflects increasing ownership, impact, and scope with meaningful jumps in salary and equity.
We review levels every 4 months. Promotions are based on output and ownership, not tenure.
This isn’t a comfy engineering role. It’s fast, focused, and customer-obsessed.
You will build fast. You will learn fast. You will own what you ship.

The Process
In just 3.5 hours, you’ll be wanting early access, just like the rest of our team—to dive into the codebase and help build a generational company, even before you start as you'll be able to see the opportunity to transform your career.
