About Onebrief

Onebrief builds collaboration and AI-powered workflow software for military planning and operational coordination.

Military planning is complex by nature, requiring teams to coordinate information, people, and decisions across systems and locations. Onebrief brings planning, collaboration, simulation, and AI into one connected environment, helping teams test strategies, adapt to changing conditions, and make decisions with greater clarity when the stakes are real.

We are a distributed team of builders from military, operational, and technology backgrounds who care deeply about improving how important work gets done. Some team members work remotely, while others work directly alongside customers in operational environments around the world.

Founded in 2019, Onebrief is backed by leading investors including General Catalyst, Battery Ventures, Insight Partners, Sapphire Ventures, and Human Capital. Valued at more than $2 billion, we continue to invest in product innovation, AI capabilities, and team growth.

Why This Role Exists

Onebrief is hiring a Principal Integration Manager to own the execution and growth of Onebrief’s work supporting the Next Generation Constructive (NGC) program. This role has end-to-end ownership of Onebrief's contributions to a multi-million dollar government program, ensuring successful delivery while positioning the initiative for continued year-over-year growth.

Reporting to the Head of Key Initiatives, you'll serve as the program lead across government stakeholders, internal teams, and industry partners, with direct visibility and escalation to Onebrief's executive team. You'll quarterback the program by aligning teams, managing risk, and ensuring customer commitments are delivered while balancing government expectations with contractual obligations.

This is a senior individual contributor role responsible for Onebrief's execution and performance within the NGC program rather than personnel management. Success requires someone who can operate effectively within both large government programs and a fast-paced startup environment.

What You'll Do

Core responsibilities:

• Own outcomes for Onebrief's contributions to the NGC program, schedules, milestones, risks, deliverables, and customer commitments.

• Work alongside leaders in other departments to assemble a purpose-built, matrixed in, cross-functional team oriented exclusively on the success of the program.

• Quarterback the program by coordinating government stakeholders, internal teams, vendors, and industry partners to keep execution aligned and moving forward.

• Manage program scope by interpreting Statements of Work (SOWs), aligning customer requests with contractual obligations, and partnering with Legal on contract modifications when needed.

• Lead program planning, customer engagements, internal and external reviews.

• Oversee milestone execution, and risk management while providing internal cross functional guidance and oversight to technical leads.

• Identify opportunities to improve program execution, reduce costs, and support future program growth.

Minimum Qualifications

• Strong understanding of operational planning, defense acquisition, or large headquarters environments.

• 10+ years of experience managing Government Programs of Record (PoRs) within the defense technology industry.

• Proven ability to influence without authority and communicate effectively across cross functional internal teams, customers, and external partners.

• Demonstrated experience owning large government programs, including schedules, contractual scope, stakeholder management, and risk management.

• Ability to navigate ambiguity, balance competing priorities, and influence government stakeholders while maintaining strong customer relationships.

• Current Active Secret clearance with eligibility for Top Secret/SCI

• Ability to travel up to 50% of the time, including travel to locations such as Orlando, Florida, and Leavenworth, Kansas.

Preferred Qualifications

• Experience with defense software, SaaS, or systems integration programs.

• Experience supporting Army modernization or command and control programs.

• Experience working in a startup or high-growth technology company.

• Existing relationships within the DoD acquisition community.

• Experience managing multiple vendors as a prime contractor, Lead Systems Integrator (LSI), or equivalent program leadership role.

Indicators of Success

This role will evolve as priorities change, but the outcomes below reflect what success typically looks like in the first six months.

A successful Principal Integration Manager will:

• Deliver customer milestones on time while keeping the NGC program on schedule.

• Align customer expectations with contractual obligations and proactively resolve scope and execution risks.

• Work with inter-departmental leads to assemble purpose-built teams oriented on program success; coordinate with these leads to resolve resourcing issues, performance issues, or prioritization.

• Build trusted relationships across government stakeholders, vendors, and internal teams.

• Improve program efficiency while protecting profitability and positioning the program for future growth.

• Provide clear direction and orchestrating cross-functional workflows to hit program milestones.

• Develop and implement internal program management practices that can be repeated and scaled across the company as Onebrief enters into more Program of Record contracts.
