Job Description

Packetlabs is hiring an OT Security Penetration Tester / OT Security Consultant to evaluate Operational Technology (OT) environments and surface real risk while avoiding operational disruption. The work focuses on security architecture reviews, OT risk identification and assessment, and client advisory designed to strengthen security programs with restraint and credibility.

This role supports Packetlabs’ expanding OT practice through disciplined testing methodology, clear risk communication, and ongoing improvement of how engagements are scoped and delivered for sensitive, legacy networks.

Key Responsibilities

Conduct holistic tabletop reviews across OT environments, covering both technical and non-technical risk without performing high-risk manual or automated testing activity
Identify areas of negative impact, high risk, and single points of failure (SPOF) in sensitive, legacy networks
Use structured judgment to determine where risk is concentrated and where controls are missing
Adjust review depth and approach based on the operational realities of each client environment
Identify vulnerabilities and weaknesses across OT environments, including Industrial Control Systems (ICS), SCADA, and field devices
Assess legacy and sensitive networks where conventional testing methods carry unacceptable operational risk
Separate theoretical risk from operationally relevant risk so findings remain actionable
Prove impact where appropriate, exercising restraint when the environment requires it
Support OT clients in improving security programs by identifying needed critical controls
Refine testing scope collaboratively as engagements progress and the environment becomes clearer
Translate technical findings into guidance that clients can act on across both technical and leadership audiences
Build client confidence through credibility, clear communication, and operational awareness
Contribute to the maturity of Packetlabs’ OT testing methodology and practice
Stay current on OT threats, attack techniques, and defensive controls
Share knowledge with the broader team to reduce blind spots and strengthen collective capability
Help raise the standard of OT security work across the firm

Requirements

No egos and a humble approach to learning and client improvement
Customer-first mentality with strong communication and professionalism with clients, project managers, and teammates
High personal standards and pride in the quality of deliverables
Commitment to digging deeper into findings to establish impact, with understanding that restraint is required in sensitive OT environments
Ability to adapt to consulting-style work in rapidly changing environments
Commitment to continuous learning and staying current as cybersecurity evolves
Self-motivated and dependable, taking ownership of outcomes without needing close management
Must be located in Texas or Florida
Graduate of an Information Security or Computer Science degree program
Professional qualifications preferred (one or more): GICSP, GRID, GCIP, CSSA, CACE, CISSP, OSCP
3+ years of experience assessing or operating within OT, ICS, or SCADA environments
Strong understanding of operational constraints that differentiate OT testing from IT testing
Excellent analytical and problem-solving skills with the ability to work independently in unfamiliar or highly specialized environments

Benefits

Immediate and ongoing offensive security training, mentorship, and professional development
Opportunity to help shape the growth, direction, and methodology of Packetlabs expanding OT practice
Leadership team that values substance, quality, and disciplined execution
Collaboration with a highly skilled team of security professionals focused on technical excellence
Competitive compensation and growth opportunity
GRRSP with corporate matching in Canada
Participation in corporate benefit plans within Canada
Flexible work environment designed to enable employees to do their best work
Fully remote work within Texas or Florida

What Success Looks Like

Clients gain a clear, accurate understanding of OT risk without operational disruption
Findings are credible, impactful, and actionable for both technical and leadership audiences
Engagements are delivered to a consistently high standard with strong client confidence
Scope is managed well as engagements evolve, with risk surfaced early and clearly
Packetlabs’ OT methodology and practice continue to mature through your contribution
Clients trust Packetlabs as a partner that understands the stakes of testing sensitive environments

Location: Texas (remote). Minimum experience: 3 years.
