Filed is building the first AI tax preparer trusted by America’s accounting firms.

Taxes might seem boring, but they are the $5 trillion backbone of the US economy. Globally, nearly $15 trillion in taxes is collected every year. Behind every dollar of it sits a professional making judgment calls, and the industry that does this work is breaking under a talent shortage no one has solved. We're fixing it. Today, hundreds of firms run Filed inside the systems they already use, and we're backed by Northzone, Neo, Analog, and Raine.

This is an incredibly hard problem to build for. Tax professionals scrutinize technology intensely, and for decades no solution has reached their level of accuracy. Until now.

What makes it hard is that tax is filled with subjectivity. General accounting can be binary, where the saying goes that "numbers don't lie". Tax runs on professional judgment. Give two tax professionals the same task and you can get two different results where no one is wrong. Both are correct. Harnessing AI for a world where multiple outcomes are correct in the eyes of the users creates a dimension of challenge few vertical AI companies ever face.

In under two years, Filed has become the market leader in the space and is reaching escape velocity. It's now Filed vs. the incumbents.

There has never been a more exciting time to work on a problem this complex. Join us while "I was there when it all started" is still true.

What we should tell you about the role:

We're looking for a Fullstack Engineer who moves fast and thrives in high-velocity environments. You're the kind of person who sees a product gap, understands the root cause quickly, and ships a working feature in hours or days, not weeks. You love turning complex workflows into clean, intuitive interfaces, and you don't wait for a perfect spec to get started.

You're a builder who's just as comfortable designing React UIs and TypeScript APIs as you are wiring up Python backends or deploying to Google Cloud or Azure. You sweat the details, but never let them block momentum.

At Filed, engineering means more than owning the code. You own the outcome. You ship a feature, watch how CPAs use it, look at the metrics, and decide what the next version should be. Just you and your team, the data, and the user.

As one of our core engineering hires, you'll help shape how tax professionals experience AI-assisted work end to end. You'll work closely with the AI, tax, and product teams - and most importantly, our users - to rethink what great AI native software can feel like.

Here’s why this is a terrible job:

• This is not a job for someone who likes to move slow.
• We operate week to week with ruthless speed. Sometimes we're going in the wrong direction, but more times than not we're going in the right direction.
• If you need a few extra days to polish a component, chances are there's already a handful of team members blocked behind you.
• You'll look at the usage data and figure out what to build next yourself.
• There are no clear answers. Just judgment calls, ambiguity, and constant input from every direction.
• You'll ask yourself, is this really the work? It is. And it's not for everyone.

⸻

Here’s why it’s the best career choice you’ll make:

• We're building what tax pros call impossible. A product that behaves like a teammate, not just another tool.
• We run reviews every 4 months. We operate with total transparency around pay, performance, and progress.
• You'll be paid above market. You'll earn equity that grows fast. And you'll have full autonomy to make high-impact decisions.
• You'll ship features because you believe in them, not because they got signed off.
• You'll talk to customer facing teams and will be exposed to customer feedback weekly. You'll drive outcomes end to end.
• We'll tell you what needs to be achieved. How you get there is on you.

⸻

The teammate we’re looking for:

• Thrives at solving hard product problems, not just technical ones
• Moves seamlessly between identifying problems, implementing solutions, and iterating quickly
• Excited by ownership - you want to be the person accountable for how a feature performs
• No lone wolves - we need a collaborative builder
• Big bonus if you've shipped product at a fast-moving startup before

⸻

What you’ll be responsible for:

• Building and maintaining fullstack features across our AI tax prep, planning, and review products
• Owning the UX and backend logic for the workflows tax professionals use every day
• Shipping fast, watching metrics, and deciding what to improve next - without being told
• You want to learn about LLMs and how to make them work for our customers to achieve higher accuracy and transparency
• Keeping the codebase clean, typed, and fast as we scale

⸻

Your hard skillset:

• Comfortable in TypeScript, React, and Python - you've built complex, data-heavy UIs and backend services before
• Familiar with cloud infrastructure on Google Cloud and/or Azure
• Bonus if you've worked in fast-paced startups or regulated industries
• Even bigger bonus if you've taken a product from 0 to 1 and watched real users depend on it

⸻

Your soft skillset:

• Comfortable being uncomfortable and making calls with incomplete data
• Empathetic and curious - building for the user, not just for clean code
• Highly collaborative across product, engineering, and tax
• Detail-oriented but pragmatic - you know when polish matters and when to ship
• You own your work and welcome the accountability that comes with it

Growth and Levels:

1. 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.
2. We review levels every 4 months. Promotions are based on output and ownership, not tenure.
3. This isn't a comfortable CRUD role. It's fast, focused, and customer-obsessed.
4. You will launch fast. You will learn fast. You will own what you ship.
