Full Stack Developer (Python/React)

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](https://techcrunch.com/2025/05/21/filed-raises-17m-to-automate-the-drudgery-of-tax-prep/). Our focus now is to deliver the roadmap and continue to win. ### What you'll build As a Fullstack Developer, you'll build the product surface and the platform underneath it: - The workflows tax professionals live in every day, from document intake through review to delivery - Deep integrations with the tax software firms already use, so Filed works where they work - The pipelines that move documents, data, and returns reliably at scale, through the most intense weeks of tax season You'll ship across the stack, own features end to end, and see your work in front of some of the most demanding professional users in the world within days, not quarters. ### 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 - Learning about LLMs and making 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 ### A championship team 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. ### What Filed stands for Not posters. Not corporate language. Real operating standards. **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. ### Who this suits This is a very fun environment, but it only suits people who meet the criteria we're looking for: - People who want to win - People who have a point to prove - People who want to write their own job descriptions ### How we pay 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. This role is assessed at Level 3 (Mid-Level). The salary and equity bandings are: - **Most Equity:** 68,750 SEK per month + $150,000 of equity - **Great Equity:** 75,000 SEK per month + $100,000 of equity - **Good Equity:** 81,250 SEK per month + $50,000 of equity 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 know you're suited to a more senior role, don't shrink to fit. Apply to the Senior Fullstack Engineer role instead. ### Benefits - A minimum of 30 days of ho
