Business Tax Expert

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 by expanding our already 30-person team with those who want to say “I was there when it all started.”

What we should tell you about the role:

We’re looking for a Business Tax Engineer with deep expertise in U.S. business tax preparation to join our team.

Mission: Over the next 12 months, this role will lead the development and refinement of business tax frameworks to train our AI models, ensuring accurate, efficient, and scalable automation for complex U.S. business returns.

You’ll work closely with engineering, machine learning, and product teams to integrate tax expertise into our systems, identify and solve edge cases, and build the processes that power our AI-driven business tax workflows. This isn’t just about preparing returns—it’s about building the backbone of how AI learns to do them.

⸻

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 perfect a return or framework, chances are there’s already a handful of team members blocked behind you.

• You’ll be operating at the intersection of tax expertise, AI training, and high-trust workflows.

• 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 design and test frameworks that will fundamentally change how business taxes are prepared in the U.S.

• You’ll talk to customers weekly. You’ll drive outcomes end to end.

• We’ll tell you what needs to be achieved. How you get there is on you.

• We expect you to build an internal tax “oracle” so dialed in that we can predict and solve issues before they happen.

⸻

The teammate we’re looking for:

• Thrives at solving complex, systems-level tax challenges

• Moves seamlessly between strategy, execution, and iteration

• Excited by the challenge of building frameworks to train AI in business tax logic

• No lone wolves — we need a collaborative operator

• Big bonus if you have a track record of owning measurable accuracy improvements, not just completing returns

⸻

What you’ll be responsible for:

1. Establish the business tax knowledge framework for AI training, covering core workflows, complex scenarios, and edge cases for 1065, 1120, and 1120-S returns

2. Integrate and validate business tax logic in the model, running targeted tests to confirm accuracy and compliance while collaborating with engineering & ML teams

3. Evaluate model outputs for business returns and implement targeted improvements based on accuracy findings to enhance performance and reliability

⸻

Your hard skillset (non-negotiable competencies):

1. Expertise in U.S. business tax preparation — Extensive hands-on experience preparing and reviewing complex 1065, 1120, and 1120-S returns, including multi-state and industry-specific scenarios

2. Framework and process development — Experience designing structured workflows, decision trees, and documentation to capture tax logic for training AI models

3. Analytical accuracy and attention to detail — Proven ability to identify errors, edge cases, and compliance issues before they impact the final return or model outputs

4. Cross-functional collaboration — Ability to clearly communicate tax concepts to engineering, ML, and product teams, translating technical tax requirements into actionable build steps

5. Creative problem-solving in tax automation — Track record of designing innovative approaches to improve accuracy, efficiency, and scalability in tax processes

Required Technical Skills / Software Expertise:

• Must be proficient in at least one major business tax software (Drake, UltraTax, GoSystems, Axcess, or ProConnect) — ideally multiple

• Comfortable working in spreadsheets (Excel/Google Sheets) for testing, documentation, and framework mapping

• Experience with collaborative tools (e.g., Miro, Notion, or similar) for process design and documentation

⸻

Your soft skillset:

• Comfortable being uncomfortable and making calls with incomplete data

• Empathetic and curious — building for the user, not just for the checklist

• Highly collaborative across product, ML, and engineering teams

• Detail-oriented but pragmatic — you know when precision matters and when to move

• 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 comfy tax prep role. It’s fast, focused, and high-impact.

4. You will ship frameworks fast. You will test fast. You will own what you build.

⸻

The process:

• Quick intro call (30 minutes)

• Technical walkthrough and async task (60 minutes)

• Final round with our team (120 minutes)

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. Because you’ll see the opportunity to change your career trajectory—fast.
