You’ll work in a remote-first, globally distributed environment, collaborating closely with product, platform, and engineering teams. Strong technical ownership, communication, and architectural thinking are essential.


Customer Overview:

USA influencer marketing platform for organizations looking to advance their creator marketing. Its enterprise-grade technology and industry-leading intelligence facilitate scaled creator discovery, streamlined workflows, and robust reporting, while ensuring compliance and brand safety.

  • Lead refactoring efforts to improve performance, readability, and long-term maintainability
  • Build, deploy, and operate services on AWS (Lambda, API Gateway, and related services)
  • Write and maintain unit and integration tests
  • Review, validate, and improve code generated with AI tools—never blindly accept AI output
  • Identify technical risks, bottlenecks, and opportunities for improvement
  • Clearly communicate technical decisions, trade-offs, and solutions in written and spoken English
  • Create short video walkthroughs or demos explaining architecture changes or completed work
  • Collaborate effectively in a remote, async-first cross-timezone team with flexible working hours

  • Experience writing testable code and maintaining automated test suites
  • Fluency in English (written and spoken)
  • Excellent problem-solving, debugging, and communication skills
  • Highly proactive and self-directed; able to unblock yourself without waiting for instructions

AI & Developer Tooling Expectations

  • Experience with AI coding tools (e.g., GitHub Copilot, ChatGPT, Claude Code, Cursor)
  • Using AI within IDEs such as VS Code or PhpStorm
  • Critically reviewing, testing, and refining AI-generated code
  • Understanding risks, edge cases, and limitations of AI-assisted development
