Criminal Investigator (CID Agent)

The most direct civilian matches sit in federal and civilian law enforcement, corporate investigations, and private security. The standout is the federal special agent path. BLS groups detectives and criminal investigators under code 33-3021 with a median annual wage of $99,430 (BLS OEWS May 2024), and federal agencies like the FBI, HSI, DCSA, and IRS Criminal Investigation hire heavily from cleared military investigators. The federal route is competitive and age-restricted for primary law enforcement positions (most agencies cap entry-level agent applicants at 37), so timing your application matters.

Civilian police detective roles also fall under 33-3021 ($99,430 median, BLS OEWS May 2024). Many large departments give military investigators advanced standing or accelerated detective tracks. Corporate and private investigation is the other large lane. Private detectives and investigators (BLS 33-9021) had a median annual wage of $52,370 (BLS OEWS May 2024), with the top end far higher inside corporate security, financial institutions, and specialized fraud units. Be honest with yourself about geography here: federal agent positions cluster around field offices and major metros, and corporate investigative roles concentrate in financial centers.

Fraud and financial-crimes investigation is worth a hard look if your CID time touched white-collar cases. Financial examiners (BLS 13-2061) earned a median of $90,400 (BLS OEWS May 2024), and banks, insurers, and payment processors run large internal investigations units. The skills cross over cleanly. If you want to see how the same investigative skill set translates in other services, the Navy Master-at-Arms and Coast Guard Investigator (IV) guides cover parallel paths. The defense contractor jobs with clearance article is useful if you want corporate investigations work that keeps your clearance active.

Federal law enforcement is the strongest GS lane for a 5821, and the anchor series is GS-1811 Criminal Investigator. This is the classification the FBI, HSI, ATF, Secret Service, DCSA, and DoD Inspector General offices use for special agents. GS-1811 has a positive education requirement waiver path for candidates with qualifying investigative experience, and your CID case work is exactly the specialized experience the standard asks for. Entry is commonly GS-7 to GS-9 with the journey level at GS-12 or GS-13 in most agencies. Note the maximum-entry-age rule for primary 1811 agent positions, which makes applying earlier in your transition window important.

Beyond 1811, look at GS-1801 General Inspection, Investigation, Enforcement and Compliance for inspector and compliance-investigator roles that are not full agent positions, and GS-1810 General Investigating for background-investigation and administrative-investigation work (DCSA personnel security investigations live here). GS-0083 Police covers federal police officer roles at GS-5 through GS-8, useful as a faster-hiring entry while a 1811 application processes. GS-0080 Security Administration fits if you pivot toward physical and personnel security program management, and GS-0132 Intelligence is in reach if your billet leaned into the analytical or counterintelligence-adjacent side.

Your TS/SCI is a major lever here. Agencies pay to investigate and grant clearances, so an active one cuts onboarding time and cost. Veterans' Preference applies on top, and as a CID agent you likely qualify for the more competitive announcements. For the mechanics of the GS-1811 application, the 31D CID to federal LE guide walks the same series, and the GS-0080 Security Specialist federal resume guide covers the security-program track.

If you are applying to a police department, a sheriff's office, or a federal agent posting, the people reading your resume already speak investigations. Keep the terminology. This section is for the careers OUTSIDE law enforcement and security, where a hiring panel has never heard of CID, AATP, or a CIDSAC certificate and will score only what they understand.

The pattern is to name the business outcome, then the scale. A corporate compliance or audit manager does not care that you "worked cases." They care that you ran fact-finding investigations end to end, documented findings to an evidentiary standard, and produced reports that held up under adversarial review. Here are translations aimed at non-LE roles:

• "Conducted felony criminal investigations under DoD jurisdiction" becomes "Led complex fact-finding investigations from intake to final report, managing evidence, interviews, and documentation to a standard that withstood formal review."
• "Maintained chain of custody on physical and digital evidence" becomes "Administered records and evidence control with full audit-traceability across the case lifecycle, ensuring integrity for downstream legal and compliance review."
• "Conducted subject and witness interviews and interrogations" becomes "Performed structured stakeholder and subject interviews to gather, corroborate, and document factual findings under time pressure."
