Sigma Defense is hiring a Cybersecurity Engineer V. The company announced it is seeking someone to join its team in this role. The job centers on one clear mission: making sure systems can be authorized under the Risk Management Framework (RMF) process.
This is a senior-level opening. The person who fills it will not just check boxes — they will coordinate the successful navigation of the full RMF lifecycle, from start to finish.
What the Cybersecurity Engineer V Role Involves at Sigma Defense
The main job is to keep systems moving through the RMF process so they can be authorized. That means the engineer works across the entire lifecycle, not just one stage of it.
According to the job posting, the Cybersecurity Engineer ensures systems are able to be authorized following the RMF process and coordinates the successful navigation of the full RMF lifecycle.
The role also calls for evaluating the security posture of complex systems and executing procedures tied to that work. In simple terms, this person has to look at how secure a system really is, then act on what they find.
Requirements: 10+ Years and eMASS Experience
Sigma Defense has set clear requirements for applicants. These are not entry-level expectations.
- 10+ years of relevant cybersecurity experience
- Experience using Enterprise Mission Assurance Support Service (eMASS)
- Ability to evaluate the security posture of complex systems and execute procedures
The eMASS requirement stands out. eMASS is the tool named directly in the posting, and the company expects applicants to already know how to use it. Combined with the 10+ year experience bar, this points to a candidate who has spent years inside the RMF process, not someone learning it for the first time.
Equal Opportunity Employer Commitment
Sigma Defense Systems states it is an Equal Opportunity Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, or protected veteran status. The company also states applicants will not be discriminated against on the basis of disability.
The posting carries the Equal Opportunity Employer/Veterans/Disabled designation, which signals the company's stated commitment to fair hiring across these groups.
Our Take: A Narrow, Senior-Level Search
To put it plainly, this is a specialized hire, not a broad one. Sigma Defense is not casting a wide net. The 10+ year experience requirement and the specific eMASS skill set narrow the pool fast.
In our view, the interesting part is what the role says about how serious the company is about RMF compliance. RMF work is detailed and unforgiving — a system either gets authorized or it does not. Hiring a dedicated engineer at this level shows the company wants someone who owns that outcome end to end.
For readers in cybersecurity, the takeaway is simple. If you have spent a decade in the field and know eMASS well, this is a role built for your exact background. If you are earlier in your career, this posting is not the door — but it is a clear picture of what the senior RMF path looks like.
For everyone else, this is a reminder that cybersecurity hiring at the senior level is still focused on specific, verifiable skills. General experience is not enough here. The posting names the tool, names the process, and names the years. That is the bar.
