Kunai builds full-stack technology solutions for banks, credit and payment networks, infrastructure providers, and their customers. Together, we are changing the world’s relationship with financial services. At Kunai, we help our clients modernize, capitalize on emerging trends, and evolve their business for the coming decades by remaining tech-agnostic and human-centered.
We're building a new abstraction layer that gives applications — regardless of language — safe, consistent access to data living in our core banking system, without those applications ever needing to interact with the core directly. This layer sits between our banking core and every downstream data product and application that consumes its data.
You'll join as a Senior Backend Engineer working primarily in Go. You'll partner closely with our Profile Engineer, who owns the core-side implementation in FIS Profile's proprietary scripting language (PSL), while you build the integration layer that sits in front of it. You won't be writing new product-facing API endpoints — your focus is the layer underneath: data extraction, modeling, and the access patterns that let other teams' applications consume this data safely.
What you'll do
Design and build Go services that transform data surfaced from our core banking system into a consistent model usable by any downstream application
Partner with our Profile engineer and data engineers to define clean extraction points from the core — you won't write PSL yourself, but you'll need to understand enough of the data model and business-process mapping to design the right abstraction around it
Build and maintain the access layer (APIs and/or event streams) that lets other teams integrate with this data without touching the core directly
Enforce data integrity, access boundaries, and schema versioning so changes in the core don't ripple out to every consuming application
Integrate with existing API endpoints maintained by other teams — this role extends and consumes APIs, it does not originate new product-facing endpoints
Help define whether new data products are served via batch, event-driven (e.g. Kafka/CDC), or real-time APIs, depending on freshness requirements
Collaborate with data engineers on the same team to make new data products viewable/queryable downstream
What we're looking for
5+ years of backend engineering experience, with Go as your primary/preferred language
Experience building integration, abstraction, or platform layers that sit between legacy systems of record and modern consuming applications
Comfort working with transactional systems and/or payments
Experience with event-driven architectures like Kafka and CDC pipelines
Prior exposure to legacy core banking systems is a plus, though we don't expect Go engineers to write Profile/PSL themselves
Experience provisioning cloud services in AWS or other providers
