Why we exist:

Swarmer develops software that makes drones autonomous and allows them to operate together, in large, coordinated teams—no pilots needed. Our technology has been battle-tested in Ukraine—the world’s most intense proving ground for drone warfare.

In March 2026, we became the first Ukrainian defense startup to go public on NASDAQ, following a $15M Series A—the largest investment in a Ukrainian defense tech company since the start of the war.

Working at Swarmer means operating at the intersection of engineering rigor and frontline reality. The problems and environments are complex, and the stakes are very real. We built this software to enable democratic nations to defend themselves.

If you are motivated by building resilient systems that matter and by seeing the direct impact of your work, you’ll find purpose here.

Who we’re looking for:

We are looking for a Head of Integration—a technically grounded leader who will own and scale our integration function as we move from early-stage deployments into full operational tempo.

This role sits at the intersection of two critical domains:

• Vendor integration—bringing third-party systems (video navigation, comms modules, and others) into our stack.
• Customer integration—making our software run on our customers’ platforms: aerial, ground, and maritime.

This position is for someone who can take chaos, structure it, and turn it into repeatable results—fast.

What you’ll do:

1. Vendor & Customer Integration

• Manage end-to-end integration of third-party solutions into the Swarmer stack.
• Own the integration of Swarmer’s software onto customer platforms—aerial, ground, and maritime.
• Lead R&D initiatives on new platform integrations and serve as the primary technical point of contact with hardware vendors.

2. Team Leadership & Process Development

• Build and scale the integration org: define team structure, hire and develop leads, grow a team across multiple sub-teams.
• Design and implement structured, predictable integration workflows to ensure consistent delivery timelines for every new customer onboarding.
• Establish and maintain documentation standards across the function, including Jira, process documentation, and integration playbooks.

What we need:

• Strong technical background: solid working knowledge of embedded systems, Linux, and hardware platforms.
• Experience managing engineering teams; comfortable leading multiple sub-teams and developing leads.
• Hands-on experience at the intersection of software and hardware.
• Systematic approach to work: ability to scope, estimate, and deliver.
• Documentation discipline—Jira, process docs, integration playbooks.
• Great organizational and communication skills: capable of aligning several stakeholders to drive project outcomes; effective cross-domain communication.
• Stress resilience, fast problem-solving, persistence, and an ownership-driven mindset.
• Excellent English level.

What would be an advantage:

• Senior embedded or Linux engineer background with a path into engineering management.
• Experience in defense, aerospace, automotive, robotics, or other hardware-intensive industries.
• Experience working with large hardware vendors.
• Familiarity with UAV platforms and their technical stack.
• Military or volunteer UAV experience.
• Technical degree (electronics, robotics, aviation, or similar).

What you’ll get:

• A dynamic environment with a unique opportunity to directly influence and see the impact of your work.
• A mission-driven role in a company building technology that directly supports Ukrainian and global defense capabilities.
• The opportunity to work on one of the most advanced and practically tested autonomy products in the defense-tech market.
• Exposure to multiple domains: hardware, autonomy, operations.
• Competitive salary, insurance, and legal benefits (reservation, etc).
• A high-ownership culture where initiative, clarity, and execution matter more than bureaucracy.

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
