Project description

We are looking for an experienced Avaloq CAPI Developer to design, build, and maintain integrations between the Avaloq Core Banking Platform and surrounding banking applications using CAPI (and related Avaloq interface technologies such as AMI). You will play a key role in extending and customizing Avaloq to meet evolving business requirements across the bank's core operations.

Responsibilities

Design, develop, and maintain CAPI-based interfaces between Avaloq and external/internal banking systems

Perform parameterization, customization, and scripting within the Avaloq Core Banking Platform

Analyze business requirements and translate them into robust technical solutions

Build and maintain reusable, high-performing, and reliable code, following best practices for software quality

Troubleshoot and resolve integration and configuration issues across CAPI interfaces

Collaborate with business analysts, architects, and cross-functional engineering teams to deliver end-to-end solutions

Support testing, release management, and deployment processes for Avaloq changes

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 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

Experience with other Avaloq interfaces (AMI, SWIFT messaging, Reporting)

Prior experience in a financial services or private banking environment

Familiarity with JIRA, Confluence, and ServiceNow

Experience mentoring junior developers or leading small technical workstreams
