Dear Hiring Committee,

I am excited to submit my application for the Department of Homeland Security – Business Development Account Executive role at BigBear.ai. With 8 + years of end‑to‑end capture management for DHS components (TSA, ICE, CISA, FEMA) and a proven record of winning $150 M+ of contracts through strategic pipeline development, I am uniquely positioned to help BigBear.ai expand its AI‑driven decision‑intelligence footprint across the homeland‑security enterprise.

Why I’m a strong fit

Requirement	My Experience & Impact
Full‑cycle BD & capture (identify → win)	Led three concurrent $50 M+ solicitations (e.g., FEMA Disaster‑Response AI Platform, ICE Advanced Analytics Suite, CISA Cyber‑Threat Fusion Center) from market research through award, delivering a 31 % win‑rate—well above the industry average.
Strategic pipeline & win‑theme development	Built a $420 M DHS pipeline in 24 months by mapping budget‑priority roadmaps (e.g., DHS‑S&T AI initiatives) to BigBear.ai’s capabilities, producing win‑themes such as “Real‑time Multi‑Domain Fusion” and “Zero‑Trust Data Governance.”
Collaboration with technical SMEs	Partnered with data‑science, cyber‑security, and cloud‑architecture teams to co‑author 10+ winning proposals that integrated BigBear.ai’s proprietary AI/ML models, resulting in a $68 M contract for a predictive logistics solution for TSA.
Customer engagement & relationship building	Maintained quarterly executive‑level briefings with DHS acquisition officers and agency CIOs; cultivated a network of 30+ senior decision‑makers across TSA, ICE, CISA, and FEMA, which accelerated capture timelines by an average of 45 days.
CRM & forecasting discipline	Championed the adoption of Salesforce GovCloud for pipeline hygiene, improving forecast accuracy from 68 % to 92 % and enabling senior leadership to allocate resources proactively.
Public‑Trust clearance	Hold an active Public Trust (Level 4) clearance; cleared for access to Controlled Unclassified Information (CUI).

What I will bring to BigBear.ai

1. A data‑driven capture playbook – Leveraging my experience with DHS acquisition cycles, I will institutionalize a repeatable process that aligns market intelligence, win‑theme development, and proposal execution, shortening win‑cycle times and increasing win‑rates.
2. Strategic partnerships – My existing relationships with TSA’s Office of Aviation Safety and ICE’s Office of Technology Innovation will open doors for joint‑venture opportunities and early‑engagement “sources‑sought” activities.
3. Thought leadership – I have presented at the DHS AI Summit and GovTech Expo, positioning my previous employer as a go‑to AI partner; I will similarly raise BigBear.ai’s profile at industry events and through targeted white‑papers.

I am drawn to BigBear.ai’s mission of delivering AI‑powered decision intelligence for national security, and I am eager to help the company become the partner of choice for DHS agencies. I would welcome the opportunity to discuss how my capture expertise, DHS network, and passion for AI can accelerate BigBear.ai’s growth.

Thank you for your consideration. I look forward to the possibility of contributing to your high‑performing team.

Sincerely,

[Your Name]
