  • Champion security and compliance by chipping in to PCI DSS audits, implementing mutual authentication, encryption, tokenization, and certificate lifecycle management.
  • Drive quality through automation, build reviews, and detailed testing across the full SDLC - from development through production validation and release support.
  • Serve as a technical leader in Agile/Scrum delivery - crafting builds, owning sprint commitments, and mentoring peers across a multi-functional team.
  • Ensure system reliability through on-call participation, incident response, root-cause analysis, and long-term remediation of production issues.

What You Will Bring
  • Master's degree or higher in Computer Science or equivalent experience; 6+ years of hands-on software build and application development experience.
  • Deep experience with payments and FinTech systems - credit card processing, ACH, wire transfers, real-time authorization, and settlement.
  • Hands-on experience crafting or building a payments ledger system, including double-entry bookkeeping, ledger reconciliation, and financial audit trails.
  • Deep knowledge of payment security standards: PCI DSS, mTLS, mutual authentication, HMAC, encryption, and tokenization.
  • Proficiency in Java and the Spring ecosystem (Spring, Spring Boot); deep understanding of JDBC, REST, OAuth, and JSON-based service development.
  • Hands-on experience with relational and NoSQL data stores (Couchbase, MongoDB, Cassandra, Hadoop) and object-oriented/functional programming with reactive and async patterns.
  • Excellent communication skills with the ability to work independently and effectively in multi-group, cross-discipline environments.
  • Familiarity with AI/ML techniques - experience with LLM integration, timely engineering, retrieval-augmented generation (RAG), or ML model serving to build intelligent payment features or operational tooling.
