What You’ll Do

Capture and proposal execution

• Own the technical response strategy and architecture for major RFI/RFP/RFQ submissions across all product lines.
• Lead development of technical solution narratives, compliance matrices, technical volumes, and SoW/SoT annexes.
• Coordinate inputs from Engineering, Operations, Finance, Program Management, Legal, and Export Control into coherent, compliant proposals.
• Support pricing strategy with cost-informed technical trade-offs, clear assumptions, and sensitivity analysis.
• Prepare technical briefing materials and position papers for use by BD and Product Heads in customer engagements.

Central tooling and knowledge management

• Own and continuously improve the central bid toolchain - ROM pricing models, BoM templates, standard SoW/SoT blocks, service/ILS options, integration reference architectures.
• Maintain a central library of validated performance claims and technical evidence (test data, combat data, TRL status) that Product Heads and BD must use in customer engagements and proposals.
• Ensure naming, specifications, and technical claims are consistent across all product families and validated with Product and Engineering.
• Develop and maintain standard proposal templates, compliance checklists, and bid process playbooks to improve speed and repeatability.

Governance and quality assurance

• Chair internal technical bid reviews (gate 0/1/2) for major pursuits to de-risk commitments before submission.
• Ensure proposed solutions align with product baselines, TRL status, industrial capacity, export constraints, and delivery timelines.
• Validate that technical content matches what Product and Engineering can deliver, preventing over-commitment or under-pricing.
• Drive continuous improvement through post-bid reviews and lessons learned across pursuits.

Support to Heads of Commercial Product

• Take content from Product Heads (market doctrine, roadmap, TRL, pricing logic, service concepts, integration options) and operationalize it into standard, reusable bid assets.
• Build and maintain product-line proposal annexes, performance evidence packs, and standard integration options for each major system and variant.
• Support Product Heads in developing ROM pricing ranges, service/ILS packages, and partnership structures for use in early customer shaping and qualification.
• Ensure periodic client reports (TRL, certification, performance updates) produced by Product Heads are supported by consistent, bid-ready materials for follow-on proposals.

Cross-functional collaboration

• Partner with Engineering and Operations to ensure feasibility and compliance of proposed solutions.
• Provide structured market and customer feedback to Product and R&D teams based on tender requirements, competitive gaps, and recurring objections.
• Work with Legal and Export Control to ensure all technical content, demonstrations, and data sharing comply with applicable regulations (ITAR, EU dual-use, national restrictions).
• Coordinate with Finance on cost baselines, pricing assumptions, and margin guidance for complex bids.

Mentorship and enablement

• Mentor Sales Engineers on proposal quality, technical storytelling, solution discipline, and compliance best practices.
• Act as escalation point and design authority for complex technical questions during pursuits.
• Train Product Heads, BD teams, and junior SEs on use of central bid tools, v
