Pre Sales Engineer

The Presales Senior Engineer is a senior technical presales leader responsible for owning complex sales engagements, shaping solution strategy, and guiding the development of high-quality proposals, estimates, and statements of work. This role partners with sales, delivery, and presales architects to align customer requirements with C3’s service portfolio and Reference Architecture standards while reducing risk and improving solution quality.

C3 Integrated Solutions works with U.S. federal and defense contractors, many of whom are small and mid-sized businesses in aerospace, manufacturing, or technology, to implement and manage IT systems and security controls that support CMMC Level 2 compliance requirements. The role must be able to position and scope solutions aligned to C3’s Reference Architecture, including core workloads such as Microsoft 365, Azure, identity and access management, endpoint management, security operations, backup, and compliance-driven managed services.

The Presales Senior Engineer plays a critical role in leading strategic opportunities, supporting standardization across the presales function, and mentoring other presales engineers.

What You'll Do:

Scoping

• Lead scoping for complex or strategic opportunities, including discovery, risk identification, solution fit analysis, and definition of delivery assumptions.
• Own the development and review of custom statements of work, change orders, estimates, and technical proposals for high-visibility opportunities.
• Provide technical leadership for pricing inputs related to licensing, cloud infrastructure, security services, and professional services labor.
• Establish and refine repeatable presales assets, templates, and scoping practices that improve consistency and quality across the team.

Technical Solutioning and Presentation

• Serve as a senior technical advisor on C3 solutions, including Microsoft 365, Azure, Entra ID, endpoint management, security platforms, managed services, backup, and compliance-aligned architectures.
• Maintain strong working knowledge of C3’s Reference Architecture and its supporting partner services, including secure access, endpoint security, allowlisting, backup, remote monitoring and management, and governance or compliance tooling.
• Maintain expertise in compliance-driven solution requirements for regulated environments, including customer needs tied to federal and defense sector expectations such as CMMC, NIST, and Controlled Unclassified Information (CUI) handling requirements.
• Act as a point of escalation for complex technical questions, custom opportunity structures, solution exceptions, and cross-workload dependencies during the presales cycle.
