    .
  • Solid experience building

  • Proven ability to design and implement integrations with external APIs.
  • Comfort working with
    AWS
    in production environments.
  • Curious, self-driven, and comfortable owning outcomes end-to-end.

Nice to Have

(Not required, but helpful)

  • Familiarity with
    .NET Core
    for reading/understanding legacy code.
  • Experience in event-driven or distributed system patterns.
  • Performance profiling or observability experience.

Why Join Mainboard

    shape the next generation
    of agency, talent, and creative-industry tech: including AI and automation initiatives.
  • 27+ years
    in the industry and still building forward.

If solving
real technical challenges
and seeing your work directly impact a global product excites you, we'd love to meet you.

When applying, please include your expected salary range and availability.
