About the company

Our client is a cybersecurity company.

The role

Raydar is recruiting for this role on behalf of our client. Own the networking and distributed systems layer of a software platform, building low-latency services that handle heavy request volumes. Divide your time between hands-on engineering and working directly with customers on their deployments.

What you'll do

  • Build protocol-aware proxies and gateways that handle several kinds of network traffic.
  • Design a very fast request path so policy checks run on every request without noticeable delay.
  • Create high-volume data pipelines and storage so activity stays searchable for investigation and analysis.
  • Lead customer deployments across cloud, private network and on-premises environments.
  • Own a product area end to end, working in person alongside the founders.
  • Spend roughly 80% of your time on engineering and 20% with customers.

What we're looking for

  • A track record of shipping and operating large-scale production systems that span many machines.
  • Deep knowledge of how network protocols work at a low level, including tuning for worst-case response times.
  • Prior work at a technology company where the underlying system is the core product.
  • Clear communication and sound product judgment for working directly with customers.

Bonus points

  • Hands-on exposure to traffic routing, request handling layers or large-scale data movement.
  • Prior startup experience.
  • Relocation support

Location and work model

  • San Francisco, CA, United States
  • On-site, 5 days per week in office
  • Full-time

Compensation, as the posting describes it
