About the role

  • Build and maintain scalable, reliable backend systems that power integrations across multiple products.
  • Collaborate with cross-functional teams (Business Development, Product, Customer Success) to define requirements and deliver solutions that enable new business opportunities.
  • Dive deep into a large, multi-product codebase — debugging, optimizing, and improving backend performance.
  • Write clean, maintainable, and well-tested code with a strong focus on operational excellence.
  • Ensure backend systems are well-documented, observable, and resilient in production.
  • Identify opportunities to automate processes, improve performance, and enhance system reliability.

Requirements

  • You love exploring and improving complex systems — not afraid to jump into unfamiliar codebases.
  • You communicate clearly and collaborate effectively across technical and non-technical teams.
  • You care about code quality, testing, and operational excellence just as much as you care about shipping features.
  • You take ownership of your work and follow projects through from idea to production.
  • Bonus Points If You Have
  • Experience working on integrations or partner-facing systems.
  • Background in AdTech, MarTech, or Data Engineering.
  • Familiarity with CI/CD pipelines and monitoring tools (Grafana, Datadog, etc.).
  • Exposure to distributed systems, large-scale APIs, or event-driven architectures.
Benefits
  • Medical, dental & vision coverage (some plans 100% employer-paid)
  • 12 weeks paid parental leave
  • Unlimited PTO + Work-From-Anywhere August
  • Career development with clear advancement paths
  • Equity for all employees
  • Hybrid work model & daily team lunch
  • Health & wellness stipend + cell phone reimbursement
  • 401(k) with employer match
  • Parking (CA & WA offices) & pre-tax commuter benefits
  • Employee Assistance Program
  • Comprehensive onboarding (Cognitiv University)
  • …and more!
