Senior Fullstack AI Engineer

We believe in radical transparency at Filed, so this job description is a little different. It starts with why this is a terrible

job. Then it tells you why it might be the best career choice you'll ever make.

This is an incredibly high-paced, high-tempo environment. We're making a generational bet to change all of our lives, and

generational bets are not comfortable.

You will build agents for subjective workflows. Tax law is objective, but what applies under it and how professionals interpret it

is full of judgment. You can give two tax professionals the same task and get two different results where both are right. We're

building agentic systems that have to reach their level of accuracy, not a level we decided is good enough. From an engineering

standpoint, this is the hardest thing most of us have ever built. At times it will feel like hitting your head against the wall.

Customers will sometimes get frustrated, because they expect deterministic results from probabilistic systems, and we're managing

the expectations of some of the biggest firms in the world, including the Big Four.

And the rhythm is real: we get to the office, we work, we go home and spend time with our families, and then many of us get back

online to support our customers in US hours. It's tough. It's relentless.

It's addictive to be part of a business when you know you're winning. Filed is adding millions of dollars of revenue every

quarter, customers are signing up in numbers, and in under two years we've become the market leader in a space with entrenched

incumbents and a drastic need for new AI tools. When we come into head-to-heads with competitors, we win every time, because our

product is superior. And we stay focused and diligent: we only work with tax firms that have the right expectations, which is why

our typical customer is mid-market and enterprise.

The industry looks boring from the outside, but the problem is unsolved, and the space has been riddled with products below the

mark for decades. When you push through the wall, there's a spark of joy: a customer says "wow, this is phenomenal." That keeps

happening.

The opportunity here is not only to make a great deal of money. It's to have real impact on our mission: making this profession

extraordinary. Nobody became a tax professional for the admin. They got into this work to be creative with tax law, to have fun,

and to change the fabric of society. Filed enables them to do exactly that.

We've raised $17.2 million to date, led by Northzone, and you can read the story in TechCrunch. Our focus now is to deliver the

roadmap and continue to win.

• Evaluation and verification systems that measure our accuracy against professional standards, not benchmarks we invented for

ourselves

You'll work at the frontier of applying AI to subjective domains, where two different answers can both be correct, and where

shipping means earning the trust of professionals who scrutinize every output.

We think of ourselves as a sports team. Incredibly high performance, incredibly high standards, and real success to show for it.

Being a championship team means working with people who are deeply proud of the work they do and have great fun doing it together.

We measure employee happiness constantly, and our eNPS is +60. We don't say that to brag. We say it because a team playing at this

tempo only holds together if people genuinely love being on it. Every four months, the whole company comes together for an

offsite.

1. No problem is someone else's problem

If you see it, it's yours. Bugs, customer confusion, missed expectations, internal friction. We don't pass problems sideways and

we don't hide behind roles. You fix the typo even if you didn't write it, jump into a customer issue even if it's not your

department, escalate early, and close loops fully. Ownership means you drive resolution, not that you suffer silently or burn out

doing everything alone.

2. Waiting is not a strategy

Momentum is our advantage. We don't wait for perfect information or stall because something is unclear. You ship a V1 instead of

debating V5, test instead of theorize, run small experiments instead of requesting big approvals, and propose solutions instead of

just naming blockers. Speed is powerful. Sloppiness is not, and recklessness has no place in a high-trust industry.

3. We run toward the fire

When something breaks, we move. Tax is high-stakes and trust is fragile. We acknowledge issues immediately, communicate clearly

and often, prioritize customer-impacting problems fast, and stay on it until it's fully resolved. Firefighting is a strength, not

panic, and never an excuse for preventable mistakes.

4. We win on customer experience

AI will commoditize. Features will copy. Pricing will compress. Experience won't. We respond faster than customers expect,

communicate proactively, think like a partner rather than a ticketing system, and anticipate needs before they're raised.

Overdelivering means raising the standard of care, not overpromising, hero culture, or burning the team out.

Nothing at Filed is behind closed doors. Everyone here sees everyone else's salary, because we believe transparency creates trust,

and trust is the foundation of excellent teamwork. Compensation isn't a negotiation. Depending on your location, everyone receives

the same three offers, and all of our offers are above market benchmarking.

We run performance reviews every four months. Meet your goals and you can expect to double your equity by the end of your first

year.

One more thing, in the spirit of transparency: some people who apply for this role will be assessed at a different level. If the

team determines your level of responsibility sits differently, we'll adjust the offer accordingly. If you're earlier in your

journey than this role expects, that's not a problem. Apply to the Fullstack AI Engineer role instead.

In just 3.5 hours, you'll be wanting early access, just like the rest of our team, to get into the stack and start building a

generational company, even before your first day.

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.

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.
