About the role You'll drive Salmon's move from a vendor-controlled SaaS processing model to a licensed, Salmon-owned processing platform — owning delivery from vendor selection through certification and production, starting with ATM acquiring. What you'll do Join the Acquiring Platform team to stand up licensed processing services, starting with Phase 1 ATM acquiring and extending toward POS and e-commerce acquiring. Work across the full integration landscape — processing platform, ATM middleware, HSM/RKL, Visa and BancNet acquiring, anti-fraud, core banking, and internal card systems on AWS/EKS. Sit at the center of acquiring engineering, infrastructure, security and compliance, payment schemes, and the external processing vendor — turning contractual commitments into executable delivery. What you'll own Own delivery of the licensed acquiring processing platform end-to-end, from scope definition to production readiness. Translate business, scheme, compliance, and operational requirements into clear technical requirements, Jira tasks, and documentation. Drive API and ISO 8583 integration design — message flows, error handling, reversals, reconciliation, monitoring, and operational processes. Manage external provider delivery: scope, milestones, dependencies, risks, acceptance criteria, UAT, certification, and release planning. Coordinate developers, QA, infrastructure, security, compliance, and operations from business request through production release. Support incident analysis, production readiness, monitoring setup, and post-release stabilization. Maintain the implementation roadmap, critical-path tracking, and decision and risk logs for stakeholders. What makes you a strong fit 4+ years as a Technical Product Manager, System Analyst, Solution Analyst, or Product Owner in fintech, banking, or payment processing. Strong understanding of acquiring, payment processing, the issuer/acquirer/scheme model, and the transaction lifecycle. Hands-on experience with complex system integrations — ideally processors, switches, payment networks, HSMs, or ATM/POS/e-commerce acquiring. Knowledge of ISO 8583, authorization flows, reversals, reconciliation, clearing and settlement, and certification processes. Experience designing APIs, integration contracts, sequence flows, operational processes, and technical documentation from scratch. Good understanding of microservices, cloud deployment, databases, monitoring, and release/change management. Ability to manage external providers and convert contractual commitments into executable delivery plans. Strong SQL and data analysis skills for transaction investigation and validation. A proactive, structured, ownership-driven mindset across product, engineering, compliance, and business teams. English B2 or higher.
