Company mission
To enable anyone, regardless of education or background, to file their taxes with newfound confidence.
Role
Who you are
- 5+ years experience in Product Management (ideally in fintech or B2B). You’ve shipped things that real people use, and you can point to the metric that moved when you did
- Understand implicitly the product development process - from discovery, to user research to experimentation. You are able to build and defend a compelling strategy that solves user needs
- You have a builder track record: you’ve made things with AI, not just written specs about them. Shipped products, agent workflows, or tools real users have touched. Any of these count whether at work or in your personal life
- You’re AI-native by default. You use tools like Claude, Cursor, Lovable, or similar regularly. You follow the AI product space closely and you know the difference between a demo and something production-ready
- You’ve built personal AI workflows that make you meaningfully faster. You know when to trust AI output, when to edit it, and when to reject it
- You’ve gone from user problem to testable prototype without waiting for a brief to be written for you. The output was good enough that a team shipped from it
- Low PM baggage: you’re not attached to how product management "should" be done. You care about outcomes, not territory
- Data fluency: you know the metric you were trying to move, and you can say whether you moved it, with healthy skepticism about what metrics do and don’t tell you
- You believe in experimentation and ship with velocity to learn quickly. You know your way around AB tests and are excited to try new data science models to learn faster
- You’ve worked on products where getting it wrong has real consequences for real people, and that raised your bar, not lowered it
- You’ve found a way through blockers rather than waiting to be unblocked. When something was genuinely impossible, you documented why and moved on
- You bring an entrepreneurial and independent mindset. You are excited about spotting opportunities and then acting on them
- Fluency in English is required (German is a plus)
What the job involves
- At Taxfix, we’re rebuilding our R&D organization around this idea. We call these people builders
- A Builder has a primary craft, one they’re genuinely excellent at, but they don’t stop there
- They stretch across product, design, and engineering as the situation demands, using AI to cover the gaps. They’re accountable to outcomes, not job descriptions
- Taxfix has put €5 billion back into our customers’ pockets and we aren’t stopping there. We operate in Germany, Spain, and the UK, and we’re in the middle of a genuine AI transformation in how we build and how we’re organized
- Assume there’s no designer to give you a Figma file. No engineer to hand the spec to. The magic is knowing what to build, why, and in what order, then making it happen
- Take a user problem from rough idea to shipped product. Write the brief, design the flow, prototype it, and get it in front of users, with as few handoffs as possible. Own the full loop
- Compress research, synthesis, and spec-writing from weeks into hours. You reach for AI tools not because you’ve been asked to, but because they’re faster. You know when to trust the output, when to edit it, and when to reject it. Use AI as a force multiplier
- You structure fuzzy problems, identify what should and shouldn’t be built, and move forward when there are dozens of possible directions. The magic is in the trade-offs, not the feature list. Turn ambiguous ideas into things users can trust
- No layers, no waiting. You’ll work closely with two or three other people who share the same model. Work in small, focused teams
- You know the metric your team is trying to move. You measure your week by what changed in user behaviour, not by how many tickets moved to Done. Be accountable to outcomes, not roadmaps
- You give feedback directly, to anyone, regardless of level. You raise blockers early and in the open. Push back when something’s wrong. Team player who raises the bar
- Across all three disciplines, you can hold your own: in Product you can identify opportunities, assess impact, and prioritize ruthlessly. In Design, you have taste: you know when something looks right but feels wrong. In Engineering, you’ve used AI coding tools to build something real, and you’re not dependent on an engineer to tell you why it’s broken
- When designing and shipping AI-enabled products, you consider privacy, safety, fairness, transparency, bias, and accountability. You assess when AI-generated outputs are appropriate for use and raise concerns when risks or limitations are identified
Our take
For many people, filing taxes is still a painstaking, confusing and outdated process. In Germany alone, around 10 million people each year decide not to claim their tax refund for this reason. Taxfix solves this problem by making it easier to file tax returns and claim rebates.
Taxfix serves as a personal tax accountant, something that many of its users don't have access to. The app functions much like any chatbot, offering in-depth guidance and optimising the tax filing process. Users can typically file their taxes in under 20 minutes using the app, which will appeal to anyone looking to save time and effort on their personal finances.
Taxfix is not alone in offering this service, but it sets itself apart from rivals thanks to its mobile-first approach. The company has been well-served by its innovative and attractive app interface and acquired its German competitor Steuerbot in 2023. A year later it entered the UK market by acquiring smaller competitor Taxscouts, establishing itself as the European leader in its sector.
