Focus on scalable backend services, audience targeting, campaign scheduling, delivery workflows, observability, and responsible messaging at high volume for a remote-first, globally distributed team.

Responsibilities

  • Build and evolve scalable backend services and platform primitives that power push, email, SMS, and in-app messaging.
  • Design systems for audience targeting, campaign scheduling, content orchestration, delivery workflows, and messaging preferences.
  • Improve reliability, performance, and observability for high-volume, business-critical messaging systems.
  • Partner closely with product, design, data science, and other engineering teams to build messaging experiences that drive engagement while respecting user trust and platform quality.
  • Create clean APIs, abstractions, and operational patterns that allow teams across Whatnot to launch messaging use cases safely and efficiently.
  • Contribute to experimentation, attribution, and measurement foundations so teams can understand the impact of messaging investments.
  • Help raise the bar on engineering quality through strong technical judgment, thoughtful code reviews, and solid operational habits.
  • Contribute to team-wide ownership of production health, incident response, and continuous improvement of platform reliability.

Qualifications

  • Bachelor’s degree in Computer Science, a related field, or equivalent practical experience.
  • 4+ years of professional software engineering experience building and shipping backend systems in production environments.
  • Strong experience designing, building, and operating scalable, maintainable backend services.
  • Strong technical judgment and the ability to make thoughtful tradeoffs between speed, quality, reliability, and long-term maintainability.
  • Experience working in fast-moving, cross-functional product or platform environments.
  • Comfort owning ambiguous problem spaces and turning them into clear technical plans and shipped outcomes.
  • Strong communication and collaboration skills, especially when partnering across engineering, product, design, and data.
