Senior Financial Crime Investigator

Klarna, briefly At Klarna, we're building an everyday finance network, helping over 120 million consumers across 26 countries save time and money, and worry less about their finances. Working here means taking on problems most companies never get to solve, and being hands-on enough that the interesting part of the work lands with you, not someone else — you'll build with AI, not watch it happen. This is the stretch zone. Come find out what you're capable of.

Klarna operates as a licensed bank, and every transaction that moves through the platform is a potential financial crime signal. You'll join Klarna's Financial Crime Intelligence team, an in-house group handling everything from routine reviews to the most complex, high-risk investigations in fintech. Whether your background is in fast-moving fintech, the regulatory rigor of traditional banking, or investigative work in law enforcement, you'll bring that experience to bear on real, high-stakes cases and the calls you make will reshape how Klarna detects and prevents financial crime at scale. This isn't a position where your best work gets buried in a closed case file. You'll be expected to change the system, not just clear the queue: closing a coverage gap nobody else had seen, writing a SAR that changes how a typology gets monitored, or turning a single messy case into an insight that protects thousands of others.

Your work spans three layers: Complex investigations — own the cases too nuanced, layered, or novel for standard processes to resolve, and document why, helping the team build a shared understanding of where the remit begins and ends. Intelligence — spot emerging typologies, translate signals into actionable insight, and help the team stay ahead of new fraud and financial crime patterns rather than just reacting to them. Enforcement — turn that intelligence into action: influencing transaction monitoring configuration, closing coverage gaps, and ensuring what investigations uncover actually changes the detection infrastructure, not just the individual case outcome. You'll also help build and refine Klarna's broader Financial Crime framework — shaping policy, process, and documentation to meet regulatory requirements while staying ahead of emerging risks — and work closely with internal stakeholders to maintain strong investigative controls, support transaction monitoring quality, and ensure the framework scales responsibly as Klarna continues to grow across global markets. Depending on your background, this may also include mentoring and upskilling more junior investigators, contributing to quality calibration across the team, and representing Financial Crime in cross-functional forums where investigative judgement needs a seat at the table.

You've built real depth in AML or financial crime investigations within fintech, banking, payments, or a regulatory/investigative body, or as an investigator in law enforcement — candidates coming from a law enforcement investigative background, or with experience across both fintech and traditional banking, are especially encouraged to apply. A track record of real, demonstrable impact: cases you've resolved, gaps you've closed, or frameworks you've shaped that changed outcomes beyond a single case. Strong hands-on experience conducting end-to-end transaction monitoring, event-driven investigations, and complex case escalations. Proven ability to assess suspicious activity and draft clear, well-supported Suspicious Activity Reports in line with regulatory expectations. Solid understanding of AML and financial crime regulations applicable to the US and/or EU, including sanctions and PEP frameworks, and EU AML Directives/MLRO responsibilities. Comfortable with ambiguity and complex judgement calls — high-risk cases rarely come with a clean playbook, and you're willing to make and defend a reasoned call rather than waiting for certainty. You think beyond the case
