Product Manager

At Fourthline, our mission is to fight financial crime. We help protect the global financial system by verifying millions of identities for banks, neobanks, online brokers, crypto exchanges, and insurers like N26, Trade Republic, flatexDEGIRO, Nationale Nederlanden, Qonto, Shine, Solarisbank, and more.

Having started our journey in January 2018, we're incredibly proud to count around 250 employees between our Amsterdam and Barcelona offices with over 50 nationalities.

We are looking for a passionate Product Manager to lead and grow our Biometrics product suite — one of the most technically sophisticated areas of Fourthline's Identity Verification platform. You'll work at the intersection of applied AI and financial crime prevention: turning state-of-the-art machine-learning models into production-grade products that verify human identities at scale — from automating KYC checks to enabling seamless biometric authentication for returning users.

You'll lead this product area in close partnership with the Engineering Manager and ML engineers — shaping the roadmap, driving outcomes together, and connecting technical progress to real business impact.

What you'll do:

• Lead the biometrics product area in close partnership with the Engineering Manager and ML engineers — aligning on priorities, unblocking the team, and ensuring product and engineering move in the same direction toward shared outcomes.

• Shape a clear product roadmap in collaboration with engineering and data science — grounded in technical feasibility and business priorities, and communicated effectively to commercial and leadership audiences.

• Work hand-in-hand with ML engineers to define what "production-ready" looks like for AI-powered verification checks — jointly balancing model performance, user experience, and regulatory requirements.

• Drive measurable business outcomes together with the team: improving automation rates, increasing verification conversion, strengthening fraud prevention, and building the business case for new capabilities.

• Take a data-driven approach to prioritization, using metrics like automation rates, match accuracy, and false acceptance/rejection rates — and work with the team to instrument, interpret, and act on them.

• Ensure biometric products meet the highest quality, security, and regulatory standards, including data protection requirements around biometric and sensitive personal data.

What you have:

• 5+ years of experience in a Product Owner or Product Manager role, with meaningful exposure to ML or computer vision.

• Experience in B2B

• Experience in identity verification, biometrics, or in Banking/FinTech/RegTech.

• Experience working with AI and/or R&D teams

• A genuine interest in applied AI — you don't need to build the models, but you understand the ML development lifecycle and how to turn research-stage work into production-grade products.

• The ability to connect product decisions to business outcomes — building ROI cases, defining success metrics, and communicating value to both technical and non-technical stakeholders.

• A collaborative mindset and experience working closely with engineering, data, and commercial teams to define and deliver on product requirements.

At Fourthline, we believe diversity enriches our culture and inspires you to do your best work. We value your unique talents and perspectives, welcoming them into a safe and inclusive working environment, to ultimately deliver the best products to our customers and society. You're welcome here. Fourthline is for everyone.

Our hiring process is designed to be equal, fair, and transparent. We welcome people from all backgrounds, ethnicities, genders, sexual orientations, ages, abilities, religions, and experiences in life. If you're excited about this role, but your experience does not align perfectly with every qualification in the job description, we encourage you to apply anyways. You may just be the right candidate for this or other roles.
