Proposal Development Specialist - Proposal Training Program

Proposal Development Specialist — Proposal Development Specialist Training Program

Leidos is hiring four Proposal Development Specialists (PDSs) as part of our Proposal Development Specialist Training Program (PDSTP). PDSs are high-performing, early-career professionals who want more than a traditional career path. Through hands-on experience, mentorship, and exposure to multiple proposal disciplines, PDSs develop a broad set of capabilities to discover their strengths and learn how to bring together strategy, creativity, and execution to help win business.

New to Proposals? A quick primer.

A proposal is an offeror’s written response to a customer's formal solicitation, making the case for how they will meet the customer’s mission needs and requirements and why they should be chosen over the competition. Winning proposals earn new contracts and fuel company growth, and proposal professionals plan, write, and shape offerings into compliant, compelling bids – the craft built through the PDSTP.

The Program.

The PDSTP is a two-year Training Program designed to grow agile, cross-functional proposal talent from the ground up. The program prepares high-potential, early-career employees for future proposal specialization by exposing them to the full range of proposal development disciplines and pairing them with experienced mentors who guide them throughout their rotations. Participants graduate as versatile, multi-skilled proposal development specialists ready to be deployed to the pursuits that matter most.

The Proposal Operations organization resides within Capture Operations & Excellence (CO&E), a dynamic group of experts responsible for developing winning, compliant, and compelling proposals that drive top-line growth. Our teams are fast-paced, deadline-driven, and highly motivated to win. PDSTP candidates typically have a high energy level, strong enthusiasm, a passion for persuasive storytelling, a competitive edge, exceptional writing and communication skills, and the discipline to deliver under pressure.

PDSTP participants rotate through a range of proposal development functions, which may include proposal coordination, proposal management, and writing, gaining hands-on exposure to how winning proposals come together while working alongside experienced teams and mentors. PDSs deepen their expertise in selected focus areas and apply what they've learned on live, high-priority proposals.

Throughout the program, participants build the core skills that drive winning proposals from interpreting customer requirements to crafting clear and competitive content.

In addition to the regular rotational assignments, PDSTP participants may participate in specialized trainings, conferences, and workshops, and may accept special rotational assignments as they are presented or surface during their participation in the program.
