The Context: Porters is building the operating system for autonomous banking. Having gone live with our first customers, our focus is now on making the "last mile" happen and further building out our integration with large-scale, high-security banking systems. We need an engineer to own the full integration lifecycle from architecting how we ingest data to building the APIs that allow our clients to trigger actions within our system.

The Mission: You are the bridge between Porters’ core AI engine and the complex data environments of our banking clients. You will move our integration layer to a modular, reusable adapter framework that accelerates our deployment speed while maintaining bank-grade reliability.

This job is in person (Zurich, Switzerland) or remote (CET +/-3 hours).

Your Responsibilities

• Architect Data Highways: Build and maintain custom ETL/ELT pipelines using Databricks, Snowflake, S3, or similar, to ensure seamless data flow
• Enable Bidirectional Flow: Develop "inbound authentication channels" and external APIs allowing banks to trigger Porters’ workflows directly from their internal infrastructure
• Client-Oriented Core Banking Work: Work directly with bank lead engineers to navigate security requirements and integrate with core banking systems (e.g., Mambu, Avaloq) or Open Banking APIs to solve architectural bottlenecks
• Scale the Integration Playbook: Leverage messaging/streaming services (e.g., Apache Kafka) and ELT tools (e.g., Fivetran, Talend) to automate the onboarding of new customers

Your Profile

• Experience: 5+ years in architecting integrations within Financial Services or Fintech
• Stack: Mastery of Python, FastAPI, and SQL and proven experience with unified data platforms (Databricks) and messaging/streaming connectors
• Mindset: You thrive in the intersection of deep backend engineering and client-facing solution design and are a pragmatic builder who enjoys the "0 to 1" challenge
• Bonus Points: Experience in fintech, banking, or regulated industries, particularly with open banking APIs, core banking systems (e.g., Mambu, Avaloq), or messaging/streaming services and connectors (e.g., Apache Kafka)

What We Offer

• Direct Impact: You won't be a cog in a machine. You will work directly with clients, ship fast, and see your code running in production at major financial institutions
• Founder Collaboration: Work closely with founders who have successfully built and scaled fintech and analytics products before
• Compensation: Competitive salary and significant equity on top of your compensation
• Growth: A dedicated development budget—free to use for whatever gives you a level-up
• Gear & Culture: New MacBook, merch, regular team events and dinners, a fast-paced, inclusive, and impact-oriented culture
