Jacobs is seeking a qualified Operational Technology Cybersecurity professional to support clients operating critical infrastructure and industrial environments. Your role at Jacobs enables our OT cybersecurity team to understand how clients’ systems operate, evaluate cybersecurity risks within those environments, and develop practical improvements that protect reliability, safety, resilience, and business performance.

As a member of our team, you will support clients through OT cybersecurity assessments, architecture reviews, risk analyses, secure-by-design activities, incident-response planning, cybersecurity improvement programs, and related consulting engagements. You will work with asset owners, operators, engineers, system integrators, information technology teams, and cybersecurity stakeholders to understand how systems are designed, operated, maintained, and connected.

Senior OT Cyber Engineering Professionals will need excellent analytical, problem-solving, communication, and client-service skills, as well as deep working knowledge of operational technology systems, networks, architectures, and cybersecurity concepts. This position must be able to interpret complex technical environments, resolve ambiguity, identify meaningful risk, and translate findings into practical recommendations that clients can implement.

The successful candidate will exercise professional judgment, lead defined areas of complex engagements, communicate effectively with technical and executive audiences, and produce work products that are technically sound, operationally useful, and defensible.

Bring your team-focus, adaptability, and commitment to excellence, and we’ll help you grow what drives you and deliver the world’s most challenging projects, together.
