About the role

This is a full-time remote Staff Software Engineer role for a US-based engineer with roughly eight or more years of related experience. You’ll own architecture for a self-hosted endpoint-protection platform deployed in customer-controlled enterprise, government, regulated, and potentially air-gapped environments. The role spans backend teams and sets technical direction for availability, scale, resilience, capacity, performance, and operational behavior. You’ll also lead multi-team technical initiatives and mentor senior and staff engineers.

What you’ll do

  • Own architecture across backend services, data pipelines, control logic, and customer deployment topology.
  • Set resilience standards for clustering, replication, failover, consensus, leader election, and degradation behavior.
  • Define scale and capacity approaches for varied customer hardware environments.
  • Establish performance, observability, and operations practices for restricted and air-gapped deployments.
  • Adapt cloud-native capabilities for customer-hosted architecture.
  • Set coding patterns and standards across backend teams.
  • Lead cross-team initiatives, influence roadmaps, mentor peers, and review technical work.

What they’re looking for

  • A computer science or software engineering degree, or equivalent experience, with roughly eight or more years of related work.
  • Deep Go or Python expertise.
  • Experience with PostgreSQL, MongoDB, Redis, Kafka, Docker, and Linux.
  • Extensive experience delivering on-premises, self-hosted, or customer-deployed software.
  • Experience with appliance, OVA, bare-metal, or containerized deployment lifecycle.
  • Experience with clustering, sharding, partitioning, load balancing, and capacity planning.
  • Ability to turn ambiguous, complex needs into durable multi-team designs.
  • Strong communication, roadmap influence, technical leadership, and mentoring ability.

Nice to have

  • Security-product experience.
  • Experience assessing technology trade-offs and infrastructure costs in customer-controlled or air-gapped environments.

What’s on offer

  • Base salary of $156,000–$215,000 USD, determined by candidate location.
  • Restricted stock units and an employee stock purchase plan.
  • Flexible time off, company holidays, sick time, parental leave, and grandparent leave.
  • Medical, dental, vision, 401(k) matching, insurance, FSA, employee-assistance, and prepaid legal benefits.
  • Wellness, fertility, adoption, surrogacy, home-office, mobile-phone, and pet-insurance benefits.
