About Us Concord isn't your typical consulting firm; we are an execution company with a passion for making things happen. Our mission is to help clients enhance customer experiences, optimize operations, and revolutionize their product offerings through seamless integration, optimization, and activation of technology and data. We are purpose-built, merging the industry’s top specialty companies to amplify our Innovation Capabilities in analytics & AI, data management & engineering, UX and digital experience, and technical platform integration, automation & security engineering. About the Role We are seeking a highly skilled security professional to join our client’s Customer Trust and Assurance team within a dynamic and growing cybersecurity program. In this role, you will represent the security of a modern SaaS platform by delivering accurate, engineering‑informed responses to security questionnaires, RFIs, and due diligence requests. You will work closely with internal engineers to understand how the platform is architected, validate the security design, and translate complex technical information into clear, customer‑ready explanations. You will develop deep familiarity with the product’s cloud architecture, application security controls, and threat mitigation strategies. You will articulate how the platform is built and secured to both technical and non‑technical audiences, earning trust through clarity, confidence, and technical credibility. Operating at the intersection of product security, cloud security, and customer assurance, you will help transform detailed engineering knowledge into strong customer confidence in the platform's security posture. Success in this role requires fluency in SaaS cloud architecture (tenant isolation, IAM/federation, data protection), hands-on familiarity with security frameworks including HITRUST CSF, and the credibility to represent platform security directly to enterprise security teams without escalation. What You Will Be Doing Respond to customer RFIs, security questionnaires, and due‑diligence inquiries related to security, privacy, and compliance. Collaborate closely with internal teams to gather, validate, and align accurate technical responses. Interpret and translate technical security concepts into clear, customer‑ready explanations. Support customer trust initiatives, including audits, certifications, and process improvements. Ensure timely, high‑quality delivery of all responses and maintain excellent communication throughout the customer lifecycle. Develop a deep understanding of the platform’s architecture, including cloud infrastructure, application components, identity flows, and data protection mechanisms. Articulate security design decisions, architectural patterns, and threat mitigation strategies in a way that builds high customer confidence. Partner with engineering teams to ensure externally communicated security details accurately reflect system design and controls. Enhance and maintain technical security documentation, architectural diagrams, and reusable content for customer assurance. Identify opportunities to improve clarity, consistency, and technical depth across customer‑facing security materials. Qualifications Technical: 8–12+ years of hands-on experience in cybersecurity, cloud security, application security, or software engineering, with demonstrable depth in security architecture. Proven experience in customer-facing security assurance: responding to enterprise security questionnaires, RFIs, and due-diligence requests with engineering-grounded answers, not templated responses. Strong working knowledge of SaaS cloud architectures (AWS, Azure, or GCP) from a security design perspective, including tenant isolation models, IAM/federation patterns, secrets management, encryption strategies, network segmentation, and logging/observability. Ability to discuss security design tradeoffs, attack surfaces, and control decisions at an engineering level, both internally and directly with enterprise customers. Practical familiarity with HITRUST CSF as a compliance and technical framework, with the ability to ground requirements in actual implementation detail. Experience conducting or contributing to threat modeling using STRIDE or MITRE ATT&CK on SaaS platform components such as APIs, identity flows, and data pipelines. Hands-on collaboration with engineering teams on system design reviews, security controls implementation, and architecture validation. Familiarity with SOC 2, ISO 27001, PCI-DSS, CSA STAR, and NIST frameworks; ability to connect policy requirements to technical implementation. Experience creating and maintaining architectural diagrams, threat models, and technical security documentation for external audiences. Note: Candidates should expect to be evaluated on foundational security and cloud architecture concepts during the interview process, including the ability to discuss security design decisions at an engineering level. Compliance & Customer Assurance: Familiarity with security and compliance frameworks such as HITRUST CSF, SOC 2, ISO 27001, or CSA STAR — with the ability to ground compliance requirements in technical implementation, not just policy. Experience responding to customer security questionnaires, RFIs, and due-diligence requests, with responses anchored in engineering detail rather than templated answers. Experience creating or maintaining architectural diagrams, threat models, and technical security documentation. Communication & Collaboration: Exceptional written and verbal communication skills — able to translate engineering-level security decisions into clear, accurate, customer-ready explanations for both technical and non-technical audiences. Confident representing the platform's security posture directly to customers and able to handle follow-up technical questions without escalation. Able to work cross-functionally across engineering, product, and compliance teams in a distributed environment.
