Job Summary

Join Light as an Integration Engineer building and operating production-grade integrations between Light and banking, e‑invoicing networks, and tax platforms. You’ll design multi-tenant, scalable backend integrations with external partners (banks like J.P. Morgan/HSBC), ensure data integrity, and support a modern fintech platform used by multinational finance teams.

Location: Copenhagen

Workplace: Remote

Employment Type: Full time

Job Function: Software Engineering

Key Responsibilities

•Build and operate integrations to connect Light with multi-tenant banking APIs, e-invoicing networks, and tax platforms.
•Design abstractions to turn multiple partner APIs into a coherent internal model while maintaining isolation per tenant.
•Implement reliable, auditable integrations with attention to correctness, rate limits, and production parity.
•Ensure end-to-end reconciliation and data integrity across external systems and internal processes.
•Collaborate across the stack (backend with Kotlin, frontend awareness) to ship reliable integration features quickly.

Key Requirements

•4-6 years of experience ideally, plus a track record of building integrations in production
•Hands-on experience building integrations with external systems and APIs where robustness is critical
•Direct experience with banking or payments APIs (e.g., corporate banking, treasury, or payments platforms)
•Comfort with a full-stack-ish role and being backend-focused while considering cross-stack implications
•Strong emphasis on data integrity and reliability, with experience in idempotency, retries, and end-to-end reconciliation
