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

Our customers decide what to adopt and buy in settings we can’t always be in: exercises, headquarters, symposiums, and the working groups around them. Trust is built in person, and the right conversation at the right event can open an account or expand one. Onebrief is hiring a Field Marketing Manager to own that work.

In this role, you will turn the events, sponsorships, and account programs around our target accounts into a deliberate plan: which events matter, why, who we want to meet, and what happens afterward. You will work with Sales, Growth, and Customer Relations to prioritize named accounts, give sellers the materials they need, and make sure every conversation is followed up and tracked into the pipeline. You will also bring discipline to how we measure field activity, so we can invest more in what works and stop what doesn’t.

Our field presence is growing as we expand across the services, combatant commands, federal agencies, and commercial markets. You will help decide how we show up, with real ownership from the start. Defense experience helps, but what matters most is that you run events well, care about the customer, and can show us results.

What You’ll Do

Core responsibilities:

• Field Strategy and Planning:

  • Develop and implement a comprehensive field marketing strategy to support sales growth, customer acquisition, and brand awareness for target(s) in the defense technology sector.

  • Collaborate with cross-functional teams, including sales, product marketing, and customer success, to align marketing initiatives with growth goals and sales targets.

  • Identify market trends, customer insights, and competitor activities to inform field marketing strategies.

• Event Management and Execution:

  • Own the conference and event strategy for a group of target accounts. Lead the planning and logistical execution of industry events, tradeshows, sponsorships, conferences, and webinars, from concept through to post-event analysis.

  • Partner with external vendors and internal stakeholders to create impactful event experiences that showcase our solutions and engage key customer segments.

  • Track and measure event success metrics, providing post-event reports and implementing insights to improve future initiatives.

• Campaign Development and Activation:

  • Design and manage field marketing campaigns tailored to target accounts or specific regions, ensuring alignment with overarching brand messaging and business goals.

  • Partner with the broader marketing team to develop localized content, promotional assets, and outreach tactics.

  • Utilize account-based marketing (ABM) tactics to effectively reach key decision-makers in targeted defense, federal, and commercial accounts.

• Sales Enablement:

  • Develop and deploy sales enablement materials to empower the sales team as they engage key targets and engage leads.

  • Own communications and work closely with sales stakeholders to support demand generation and pipeline-building activities that align with their goals.

• Data Analysis and Reporting:

  • Use marketing analytics tools to measure, analyze, and report on the effectiveness of field marketing campaigns, providing actionable insights for continuous improvement.

  • Monitor key performance indicators (KPIs), including lead generation, conversion rates, pipeline contributions, and return on marketing investment (ROMI).

Minimum Qualifications

• 3-5 years in marketing with 1-2 years of experience managing events. A minimum of 1 year in the defense tech industry is a plus or a related technical field, such as aerospace or cybersecurity.

• Proven experience in field marketing, event planning and management, as well as campaign management with a track record of driving successful field programs.

• Familiarity with defense technology trends and terminology is highly preferred.

• Demonstrated ability to work closely with sales teams to align marketing efforts with business goals.

• Proficient in using data analytics to evaluate campaign success and ROI.

• Excellent written and verbal communication skills, with the ability to convey complex information concisely.

• Bachelor’s degree in Marketing, Business, or a related field (or equivalent experience).

Preferred Qualifications

• Experience with Salesforce, Slack, Figma, Claude, and OpenAI

• Experience with account-based marketing (ABM), marketing to buyer-groups, and demand generation strategies.

• Background in government or B2B technology marketing, with knowledge of federal contracting and procurement processes.

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 Field Marketing Manager will:

• Develop an approved FY27 field and event calendar for their assigned market sectors, with each event tied to named target accounts, objectives, budget, and success measures set in advance.

• Have run several events from planning through post-event reporting, on schedule and within budget, with booths, demos, and materials consistent with our brand and approved messaging, including any legal or export-control reviews.

• Have built a repeatable process for each event: target outreach and meetings booked beforehand, clean lead capture on site, and follow-up that reaches Sales, Growth, and Customer Relations quickly and is tracked in Salesforce.

• Be reporting on field marketing results (meetings booked, leads, pipeline influenced, cost per outcome, and return on marketing investment) in a regular, trusted format, and using it to recommend what to keep, cut, or add for future events.

• Be recognized by sales, Customer Relations, and leadership as a dependable partner who sees problems early, brings ideas, and handles logistics, vendors, and approvals without being chased.
