# Senior Backend Engineer (Golang) at Kunai

- **Company:** Kunai
- **Location:** United States
- **Work type:** remote
- **Posted:** 2026-10-16
- **Last confirmed live:** 2026-10-20
- **Apply:** https://job-boards.greenhouse.io/kunai/jobs/5254662007

## Job description

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

US Remote · Compensation depends on location but is generally between 140 - 170k base with an up-to 20% annual bonus.

Our success over the past 20 years is rooted in our exceptional team, which thrives in a culture of collaboration, creativity, and continuous learning.

We are proud to offer our employees a range of benefits, including competitive compensation, professional development opportunities, and flexible work arrangements, all designed to help them thrive. As we continue to expand, we remain committed to cultivating an environment where people feel valued, have a voice, and are given the tools to grow—both personally and professionally—while pushing the boundaries of innovation in the fintech industry.

Minimum Degree Required:

- Bachelor’s Degree, in lieu of a degree, demonstrating in addition to the minimum years of experience required for the role, three years of specialized training and/or progressively responsible work experience in technology for each missing year of college is required

- **Key Metric**: Acquired by PwC in August 2025; 25 employees as of the acquisition announcement
- **Notable Investors/Partners**: PwC (acquirer); clients include the world's largest banks and leading payment networks

## Competitive Advantages
- Deep domain expertise in financial services, with a team that hails from the biggest names in banking, fintech, and financial services.
- A "tech-agnostic" approach that allows them to choose the best technology for each client's specific problem.
- A rapid-prototyping model that helps clients (especially CFOs) see early evidence of ROI before committing full budgets to large-scale transformations.

- **Engineering Culture**: The team is made up of mid- to senior-level engineers who are described as "evangelists for software best practices." The company is human-centered and tech-agnostic, encouraging engineers to think outside the box and solve problems that haven't been solved yet.
