About the Role

Apollo.io is hiring a Staff Backend Engineer to lead the technical direction and execution of complex, high-impact initiatives. As an AI-native company driven by a mission to help customers unlock their full revenue potential, we're looking for an engineer who thrives on ownership, collaboration, and staying ahead of the curve.

What You'll Do

  • Architect and build scalable, high-availability systems that run 24/7 and support mission-critical workflows.
  • Own and deliver multi-tier, high-volume applications with performance, accessibility, and resilience in mind.
  • Write high-quality, maintainable code with a strong focus on developer experience and system performance.
  • Drive and uphold engineering best practices, including code reviews, test coverage, monitoring, and observability.
  • Provide technical leadership across cross-functional teams, guiding architecture, trade-offs, and execution.
  • Mentor and sponsor engineers to grow their impact and deepen engineering culture.
  • Lead large-scale, cross-team projects from concept to production.
  • Deliver clear, objective feedback to peers and junior engineers through structured reviews and 1:1s.

What We're Looking For

  • 10+ years of deep experience building and scaling backend systems in production environments.
  • Proven ability to develop features with performance, reliability, and scalability in mind.
  • Strong product intuition—balancing technical scope with MVP delivery.
  • Expertise with message queues, background jobs, and distributed system patterns.
  • Familiarity with observability tools (e.g., GCP Logging, Prometheus, NewRelic).
  • Demonstrated ability to leverage AI tools (e.g., code generation, debugging, automation) and stay current with emerging AI trends.

Nice to Have

  • Bachelor’s degree in Computer Science or related field (or equivalent experience).
  • Proficiency in one or more general-purpose programming languages (e.g., Java, Python, Ruby, Go).
  • Experience integrating with third-party APIs, including handling rate limits, failure cases, and retries gracefully.
  • Experience with LLM architecture, pipelines, or applied AI tooling is a strong bonus.
