Senior Product Manager

About pdfFiller team:

We are a passionate and ambitious team of 120+ people on a mission to succeed with our online PDF creator and editor - pdfFiller.

pdfFiller empowers over 10 million users every month to create and edit PDFs, send them for signing, and securely store documents within a single application. Offering unlimited storage, unlimited templates, and cross-platform integration, pdfFiller is the only PDF editor needed to get your document done. Beyond core editing, pdfFiller helps SMB customers move fast on document-based workflows - from invoice templates and lease agreements to online fax and notarization - so they can go fully paperless and focus on running their business, while securely handling financial, legal, and HR-related use cases through e-signature workflows and bulk form response collection.

Now, we are looking for a Principal Product Manager to join us in the next chapter of growth as our brand expands and we bring new products to market.

What you will be working on:

• Own a product track end to end: strategy, discovery, roadmap, delivery and outcome. You decide what problem is worth solving, not only what gets built next.
• Run evidence-led discovery. Customer interviews, support insight, behavioral data and competitive analysis, turned into clear written problem statements and sized opportunities.
• Prioritize against business impact. Make the case for investment in your area, and against work that will not pay off, including your own.
• Ship with your triad. Partner with a designer and an engineering manager to cut work into small increments, write clear requirements, and hold quality, stability and security as non-negotiable.
• Experiment and read the results honestly. Define hypotheses and success metrics before you build, run A/B tests at real scale, and stop what does not work.
• Own your numbers. Define the KPIs for your track, monitor the funnel, and report progress, risk and learnings to product leadership.
• Work across functions and across the portfolio: marketing, support, data, and the sibling products at airSlate.

What we expect from you:

• 5+ years in product management, including at least two owning a self-serve SaaS product, or a significant surface of one, end to end.
• A track record of measurable business outcomes (conversion, activation, retention, ARPU), not a list of shipped features.
• Strong experimentation practice: designing and sizing A/B tests, interpreting results, and acting on negative results.
• Comfort with data: defining metrics, working in a BI tool, reading or writing SQL, forming and testing hypotheses independently.
• Discovery craft: talking to customers directly, and turning what you hear into problem statements a team can act on.
• Product-led growth in a high-volume self-serve funnel: paid acquisition, trial or freemium, activation and monetization.
• Shipping AI features into real user workflows, with a realistic view of where AI adds value and where it does not.
• Ability to work in ambiguity and bring structure to it.
• Comfortable using AI to significantly increase personal productivity.

Nice to have:

• Domain background in documents, workflow automation, e-signature, fintech, HR tech or legal tech.
• SMB or prosumer customers rather than enterprise-only.
• Professional working proficiency in English, B2 to C1 or above. Much of our decision-making happens in writing.
• Polish (B1 to B2) is a plus, not a requirement.
