You will be a technical "force multiplier," leading the charge in integrating AI-driven engineering (Agents and LLMs) into our core workflows.

Key Responsibilitie

• Architect Global Connectivity: Lead the end-to-end design of high-availability integration gateways, standardizing diverse banking protocols into a unified, scalable global network
• Engineer Resilience: Drive 99.99% system availability by implementing advanced distributed patterns (Idempotency, Circuit Breakers, State Machines) to ensure zero-duplicate transaction processing at massive scale
• Innovate with AI: Spearhead the adoption of AI-powered tools and autonomous agents to step-change our development velocity, automated testing, and operational reliability
• Security & Integrity: Own the mission-critical security handshake architecture that protects the financial integrity of every global transaction
• Technical Leadership: Set the bar for engineering excellence through rigorous design reviews, mentoring junior talent, and evolving our cross-border engineering culture

Job Requirements

• Fintech Mastery: 5+ years in high-throughput banking/payments. Deep knowledge of ISO 20022/SWIFT and the technical orchestration of FX lifecycles (Locked-in vs. Real-time rates)
• Technical Depth: Expert-level Java & Spring Boot proficiency with a focus on concurrency and distributed systems (Kafka, RocketMQ, MySQL optimization)
• Security Expertisee: Proven experience with "compliant by design" architecture, including OAuth2, Mutual TLS, and digital signatures
• AI-Forward Mindsett: A proactive interest in utilizing AI Agents to optimize the software development lifecycle (SDLC)
