About the role

We are looking for a Senior Software Engineer with 5-8 years of experience to design, build, and scale large distributed systems at Apollo's AI-powered go-to-market platform. You'll join a profitable, fast-growing company that's rebuilding its entire product around AI and agents, serving 500K+ companies worldwide.

You'll own significant systems end-to-end and work with a high-bar engineering team that treats AI-assisted development as a core part of how they work.

What will you be doing?

  • Own significant systems and features end-to-end, from design through production and operation, serving hundreds of thousands of companies
  • Build and operate large-scale distributed systems, selecting and combining the right technologies (Kafka, databases, etc.) to solve complex problems
  • Break down hard, ambiguous problems and drive them to shipped outcomes with clear accountability for reliability, performance, and cost
  • Build AI-native agent systems that are used by hundreds of thousands of people across the world
