Join Aprio's Information Technology team and you will help clients maximize their opportunities. Aprio is a progressive, fast-growing firm looking for a Senior Cybersecurity Engineer to join their dynamic team.

Aprio’s Cybersecurity Engineering team builds and operates the controls that make the firm defensible: identity, network segmentation, cloud security baselines, endpoint, monitoring, encryption, and vulnerability management. The Senior Cybersecurity Engineer is the senior individual contributor on that team — the engineer who takes a control domain from "documented" to "running cleanly in production," sets the standard for how it’s done, and pulls the Mid and Associate engineers up with them.

This is a hands‑on engineering role that also leads cross‑team initiatives.

This position supports U.S. Government engagements that may involve Controlled Unclassified Information (CUI) and requires access to export‑controlled technical data. In accordance with CUI and U.S. export control regulations, this position is limited to ’U.S. persons’ (including U.S. citizens, lawful permanent residents, and certain protected individuals) as defined in 22 C.F.R.

• 120.62. These requirements are only tied to this specific job posting. We are an equal opportunity employer and all Aprio employment decisions are made in accordance with applicable laws.

• You will own the operational health of one or two engineering domains, lead cross-team initiatives that touch multiple control areas, and design the patterns the rest of the team executes against.
• You’re the engineer who can take a tool from "purchased" to "deployed, tuned, and instrumented," the partner Cloud Ops and Identity call when they need a security pattern that actually works, and the senior who makes the Mid and Associate engineers better through pairing, code review, and clear standards.
• You’ll also be a senior voice in architecture and decision conversations alongside the Principal Engineer and the Manager.

• Domain ownership:
  Own the operational health of one or two engineering domains (identity, network/segmentation, cloud security baselines, monitoring/logging, encryption/key management, endpoint, vulnerability management, configuration management). Keep them measurably healthy and improving.
• Cross-team initiatives:
  Lead initiatives that span Security, IT, Identity, Cloud Operations, and delivery teams — controlled rollouts, control set hardening, tool migrations. Land them without breaking production.
• Architecture and standards:
  Design new control patterns and reference architectures. Write the decision records, runbooks, and standards the team executes against and the auditors review.
• Controlled rollouts:
  Lead the end‑to‑end deployment of new control sets (e.g., bringing a new EDR online, hardening a new cloud account, standing up new logging pipelines) — pilot, measure, expand, document.
• Mentorship:
  Pair with Mid and Associate engineers, run design reviews, give substantive code/config review, and grow the next tier. Quality of output from less senior engineers is part of your scope.
• Operational partnership:
  Be the senior partner Cloud Ops, Identity, IT Service Management, GRC, and the SOC call when they need security engineering input. Solve problems with them, not at them.
• Detection/response engineering support:
  Partner with Detection Engineering and the SOC on logging coverage, telemetry quality, and the engineering pieces of response (privileged access tooling, isolation capabilities, evidence capture).
• Evidence and audit readiness:
  Produce control evidence and architecture documentation that holds up under audit and…
