Produce clear technical documentation for both technical and non-technical stakeholders

Provide ongoing support and maintenance for existing CAPI interfaces in production

Skills

Must have

Proven hands-on experience (4+ years) developing with Avaloq, specifically using CAPI (Avaloq's scripting/customization interface)

Strong knowledge of Oracle PL/SQL and Avaloq Script

Solid understanding of core banking processes and products (e.g. payments, securities trading, settlement, client onboarding, or credit/loans — tailor to your team's focus)

Experience with the Avaloq Core Banking Platform's architecture, data model, and interface layer (CAPI/AMI)

Familiarity with software development lifecycle practices and Agile ways of working

Strong analytical and problem-solving skills, with the ability to work through complex technical requirements

Excellent communication skills, with the ability to explain technical concepts to non-technical stakeholders

Nice to have
