DroneOps is a Ukrainian defense-tech company developing alternative navigation for UAV. We're scaling in both the domestic and international markets, and we're looking for someone to build our marketing function essentially from the ground up.

Location: Kyiv, hybrid

What you'll be doing

• Define our marketing strategy: decide which audiences, channels, formats and activities we need — and which we don't — and then put it into practice
• Build the company's brand: positioning, visual and verbal identity, tone of voice — balancing transparency, security, and audience trust, as required in the defense sector
• Turn field tests and flights into proof content: short videos with real results and numbers
• Collect and package our achievements and third-party validation: test results, competitions, partnerships, media mentions
• Manage the company's social media presence (LinkedIn, X/Twitter, and other relevant platforms) — content planning, publishing, community management
• Plan key announcements as campaigns (teaser, video, details, partner follow-ups), not single posts
• Build relationships with defense and tech media and podcasts
• Develop communication strategy for two distinct audiences: the Ukrainian market (military, partners, general public) and international audiences (foreign partners, distributors, delegations, trade shows)
• Prepare materials for international exhibitions, presentations, and partner negotiations
• Work closely with leadership, sales and R&D — understand the product deeply enough to communicate its value without oversimplifying or disclosing sensitive information
• Build out the content production process: copy, visuals, video (either hands-on or by managing contractors), including security review before publication
• Track competitor communications and defense-tech trends, and adapt strategy accordingly

What matters to us

• 4+ years of marketing experience, ideally including brand-building from scratch or a rebrand
• Understanding of B2B/B2G communication — defense is not a mass consumer product
• Strong English (written is required; spoken is a plus for communicating with foreign partners)
• Professional-level social media management experience (understanding of metrics, not just likes)
• Ability to handle sensitive information and awareness of communication risks in the defense sector (a plus if you already have this; we'll train on the job)
• Self-sufficiency — readiness to build the process, not just execute a ready-made brief

Nice to have

• Experience in defense, tech, or B2B sectors
• Hands-on video editing or experience managing video production
• Comfortable representing the company publicly at exhibitions and events
• Understanding of SMM analytics fundamentals and PR
• Experience preparing for international exhibitions/events

What we offer

• Competitive salary
• Reservation from mobilization
• Office in Kyiv with shelter access, generator and Starlink
• Possibility of hybrid work format
• Impact on improving our country's defense capabilities
• 21 days of vacation + public holidays, sick leaves
