Intelligence Surveillance Reconnaissance (ISR) Systems Engineer

The 2651 is the Marine who keeps the intelligence enterprise running. Not the analyst who exploits the take, the engineer who builds and integrates the systems that collect, move, and store it. You designed and stood up ISR architectures inside the Signals Intelligence and Ground Electronic Warfare field (OccFld 26): integrating sensors into the collection chain, engineering the dataflow between intelligence systems, standing up Sensitive Compartmented Information communications, enforcing data standardization, and building the network and data redundancy plus disaster recovery that the analysts never see but always depend on.

Your pipeline backs that up. After the Basic SIGINT Operators Course at Goodfellow AFB in San Angelo, you completed the ISR Systems Engineer Course covering computer hardware fundamentals, operating systems, information assurance, database and dataflow management, radio frequency theory, satellite communications, networking, and system integration. You held SCI eligibility based on a T5 single-scope background investigation. That combination of cleared systems integration plus hands-on RF, network, and data engineering is rare, and it is exactly what cleared defense employers and federal engineering shops are short on.

This page is for the 2651 looking at what comes next. It covers the civilian engineering and systems roles your experience maps to, what they pay from BLS data, the federal GS engineering and IT series that hire this background, and how to translate a SIGINT/EW systems-integration record into language a civilian hiring manager will rank highly. Inside the Corps, the closest neighbors are the 0671 Data Systems Administrator and the 0689 Cybersecurity Technician, but the 2651 sits squarely on the engineering side. For the broader translation playbook, our guide on breaking into tech without a degree is a useful starting read.

I came up through federal environmental and engineering work after the Navy, and the 2651 record reads cleaner to an engineering hiring manager than almost anything else in the intel field. You are not selling "I analyzed reports," you are selling "I integrated sensors, engineered the dataflow, and kept a classified architecture redundant and recoverable." That is systems engineering, and the clearance is the part civilians cannot replicate. The only thing that costs you interviews is leaving it in SIGINT jargon. — Brad Tachi, Navy Diver veteran & BMR founder

The civilian market reads a 2651 record as systems and electronics engineering, not as intelligence. That is a stronger position than most intel MOSs land in, because engineering and cleared systems-integration roles pay well and the talent pool is thin. Salary figures below are BLS OEWS May 2024 medians.

Cleared defense-contractor systems engineering. Companies building and sustaining ISR, SIGINT, and EW systems for DoD hire 2651s directly into systems integration and field engineering roles. BLS groups much of this work under Computer Systems Analysts at a median of $103,790, while the deeper hardware and RF design roles fall under Computer Hardware Engineers ($155,020) and Electronics Engineers, except computer ($127,590). The clearance plus hands-on integration experience is what moves you past the resume screen here.

Network and systems architecture. Standing up the dataflow and redundancy between intelligence systems is network and systems architecture work. Computer Network Architects earn a median of $130,390, and Network and Computer Systems Administrators earn $96,800. If your record leans toward sustaining the SCI enclave rather than designing it, the administrator track is the faster on-ramp.

Information security. The information assurance side of your training maps to Information Security Analysts, median $124,910, one of the faster-growing fields BLS tracks. A 2651 who held the security baseline for a classified architecture has a real story here. Our breakdown of breaking into InfoSec after the military walks the path.

Technician and field-service tracks. If you want hands-on hardware over architecture, Electrical and Electronics Engineering Technologists and Technicians earn a median of $77,180, and field-service and support roles (Computer User Support Specialists) sit at $60,340. These are honest entry points that often convert into engineering titles once you have a civilian cert and a year of tenure.

The market is cyclical and clearance-gated. Cleared roles cluster around the National Capital Region, San Antonio, Augusta, Hawaii, and the major SIGINT and contractor hubs, so geography matters more here than in general IT. Cross-branch, the same civilian paths pull from the Navy CTM Cryptologic Technician Maintenance and Air Force 3D1X2 Cyber Transport Systems ratings. To translate a clearance into a salary number, see what a clearance is actually worth, and our guide to defense-contractor jobs for cleared veterans covers who is hiring.

Federal engineering and IT series are the cleanest fit for a 2651, and your active SCI eligibility is worth more inside the government than almost anywhere else. Two facts shape the search. First, the engineering series (GS-0854, GS-0855) carry a positive education requirement, so an engineering or related degree, or qualifying coursework, matters at the higher grades. Second, the technician and IT series do not, so they are open to experience-based qualification.

The strongest matches are GS-0855 Electronics Engineering and GS-0854 Computer Engineering, which is the federal home for the sensor-integration and systems-engineering work you did. The GS-0856 Electronics Technician series is the experience-based path into the same shops without the degree gate. On the IT side, GS-2210 Information Technology Management covers network, security, and systems-administration work, and a cleared 2651 qualifies across several of its specialties. Because your record sits in the intelligence enterprise, GS-0132 Intelligence is also in play for the systems-support side of intel organizations.

Adjacent series widen the net: GS-0801 General Engineering, GS-0391 Telecommunications, and GS-0080 Security Administration for the information-assurance and physical-security baseline of classified systems. Grade placement usually lands GS-7 to GS-11 for transitioning enlisted, with GS-12 and up reachable for those who held senior SCI architecture roles. Veterans' Preference and the VEOA and VRA hiring authorities apply across all of them. For the mechanics, read the 10 federal job series every veteran should search and how to find your military job series equivalent. The same GS engineering and IT targets pull from the Army 25E Electromagnetic Spectrum Manager page. A federal resume is its own format with strict OPM rules, and the federal resume builder is built for it.

If you are staying in systems engineering, networking, or cleared IT, your terminology already lands. Hiring managers in those shops know what a SIGINT architecture and an SCI enclave are. This section is for the 2651 targeting careers outside the SIGINT and engineering world, where "ISR systems engineer" and "dataflow integration" read as a foreign language. The goal is to translate the underlying work into business terms without inflating it.

Before and after, for a non-field role. Before: "Served as 2651 ISR Systems Engineer responsible for sensor integration and SCI dataflow." After: "Integrated distributed sensor and data systems into a single architecture serving 200+ users, engineered the dataflow and redundancy that delivered 99.9% availability, and enforced the security baseline across the environment." The second version is what a commercial systems-integration or operations hiring manager can score. Our glossary of 50 military terms translated to civilian language and the guide to converting evaluations into resume bullets go deeper. Our piece on military cybersecurity careers shows how this translation plays out in a real job search.
