Who We Are
At MAS Global Consulting, we combine world-class talent with a people-first culture to help our clients accelerate digital transformation. Our teams work with leading global companies to deliver high-quality software engineering, modernization, and platform solutions.
We are committed to excellence, continuous learning, and building long-term partnerships that empower our consultants to grow and thrive.
This opportunity places you within one of our top fintech partners, Affirm, supporting their Code Standards Team, a group responsible for ensuring a modern, safe, and high-quality code ecosystem across all engineering teams.
Who You Are
You are a Senior Kotlin Engineer with deep experience in Kotlin/JVM, Gradle, and modern tooling ecosystems. You enjoy working on large-scale modernization efforts, improving build systems, standardizing tooling, and elevating engineering quality through best practices and automation.
You thrive in distributed environments, communicate clearly, and have a strong sense of ownership. You are proactive, analytical, collaborative, and passionate about building reliable, future-proof engineering foundations.
  About the Team
Affirm's Code Standards Team owns the company's internal dependency and language modernization initiatives across Python and Kotlin. Their mission is to improve developer experience by ensuring all services run on safe, well-supported, open-source-aligned environments.
The team works closely with Developer Productivity, CI/CD, and Test Platform Engineering to define cross-language standards, build tooling for migrations, provide shared libraries, and guide modernization projects such as language runtime upgrades.
What You'll Do
  • Audit and update dependencies, replacing deprecated or bespoke internal packages with modern open-source alternatives.
  • Implement and extend build tooling aligned with Affirm's next-generation service-oriented architecture and repository structure.
  • Contribute to per-package or per-module testing and standardization to ensure safe upgrades to new Kotlin language versions.
  • Introduce linters, tooling, and guardrails to help engineers follow best practices.
  • Participate in code reviews and design reviews, maintaining Affirm's standard of "open-source quality at Affirm scale."
What You Bring
Required Experience
  • 5+ years of professional Kotlin development.
  • Deep knowledge of Gradle and Kotlin build systems (modularization, dependency resolution, version alignment).
  • Understanding of semantic and open-source versioning strategies.
  • Practical experience integrating static analysis, linting, and formatting tools into CI/CD.
  • Strong foundation in testing (unit, integration, matrix testing), especially related to version upgrades.
  • Proven ability to identify and replace deprecated dependencies.
  • Comfortable working in distributed, asynchronous engineering environments.
Preferred Experience
  • Experience upgrading Kotlin versions (e.g., 1.x → 2.x) or JVM major version transitions.
  • Experience modernizing large or legacy Kotlin codebases.
  • Experience with Python ecosystems is a plus.
  • Familiarity with Kotlin DSL, multiplatform, structured concurrency, coroutines, etc.
  • Previous contributions to developer productivity or platform engineering tooling.
