Senior Transaction Investigation Officer

About the role

You'll build our financial crime investigations function from the ground up — not inherit one. You'll lead a team of three investigators and act as the primary operational link between investigations and Compliance. This role matters because Salmon Bank's ability to catch financial crime early depends on the standard you set now, while the function is still being built.

Key responsibilities

• Review and oversee AML alerts, referrals, and suspicious activity cases, validating findings against internal systems, transaction records, and supporting documents.
• Challenge your team's investigation assessments and STR recommendations before they move forward, escalating high‑risk cases to Compliance, the MLRO, or the appropriate authority.
• Manage, coach, and quality‑assure three investigators, running case reviews that develop investigative judgment over time.
• Write and iterate SOPs, case templates, and escalation frameworks as the team scales.
• Help select and tune transaction monitoring tools such as Feedzai, Hawk AI, or Sardine.
• Report team KPIs to the Head of Payments, including alert volumes, SLA adherence, STR volumes, turnaround times, and escalation rates.

Required profile

• 5+ years in AML or financial crime investigations at a bank, digital bank, or payments fintech.
• Track record drafting STRs and working directly with a Compliance or MLRO function.
• Strong knowledge of payments typologies and financial‑crime risks specific to digital banking.
• Experience leading or mentoring investigators and teaching investigative best practices.
• Hands‑on experience with transaction monitoring platforms and case management systems.
• Solid understanding of AML/CFT regulation, BSP and AMLC requirements.
• Comfortable building in ambiguity without a finished playbook.
• Experience reviewing customer transactions and account activity in a live investigations role.
