Simpli.fi is currently looking for a Cybersecurity Engineer. You will join a security team focused on practical risk reduction across endpoints, identity, logging, and compliance operations. This role is well suited to a systems-oriented generalist who can connect dots across tools and environments, understand how failures propagate, and help the organization improve security outcomes without losing momentum.

This is an individual contributor role. This role is not siloed. You will work across endpoint security, identity, telemetry, and compliance workflows. You will have opportunities to make improvements that are visible across engineering and the broader company.

Security is part of how we deliver a great workplace experience and build customer trust. The work in this role helps employees stay productive and safe, reduces disruption from preventable issues, and supports the evidence and assurance that customers and auditors rely on.

You will have room to grow by owning meaningful outcomes end to end. That includes deepening expertise in endpoint security, identity, telemetry, and compliance operations, and learning adjacent systems through hands-on work, documentation, and automation. We prioritize durable improvements over heroics, so learning and progress are sustainable.

We aim for a sustainable pace and clear priorities. This role has broad scope because it touches systems people rely on every day, not because we expect heroics. There is no mandatory on-call rotation for this position, and most work weeks are around 40 hours. When urgent incidents happen, we collaborate to resolve them, and that can occasionally require engagement outside normal hours.

We value durable improvements, automation, and good documentation over “always available” expectations.

  • Deployment, configuration, investigations, and remediation support
• Support incident response with a focus on diagnosis, recovery, and root cause understanding
• Use logs and telemetry to investigate events and identify patterns
  • Correlate signals across systems rather than relying on a single tool
• Own operational security compliance workflows
  • Maintain and improve SOC 2 evidence collection
  • Track down evidence across systems and teams
  • Ensure controls reflect real system behavior
• Administer and improve the company’s Vanta implementation
  • Maintain accurate integrations and control mappings
  • Reduce manual evidence collection where possible
• Improve how security tooling and controls fit together through pragmatic configuration and automation
• Partner with IT and engineering stakeholders to translate technical risk and compliance needs into clear actions and tradeoffs
• Document systems, controls, and operational knowledge so improvements persist

• Strong problem solving skills with close attention to detail
• Systems thinking and pattern recognition
  • Ability to reason across endpoints, identity, networking, access controls, telemetry, compliance controls, and cloud environments
• A pragmatic security mindset
  • Able to balance risk reduction,…
