Principal Integration Engineer

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.

We’re looking for a Principal Integration Engineer. You will be responsible for the hardware composition of our products, their connectivity, and the integration of these with our software solutions. This is a great role for someone who has expert-level technical expertise, experience in embedded development, and a deep understanding of drone technologies and communication protocols.

• Hardware Design and Development: Design and develop hardware architectures for drone systems, including component selection, layout considerations, and system-level integration planning

• Embedded Systems Development: Develop and optimize embedded software for companion computers, microcontrollers, flight controllers, and other hardware components, ensuring efficient resource utilization and real-time performance

• Prototyping and Testing: Build and test hardware prototypes, conduct performance evaluations, and iterate on designs to meet product specifications and reliability standards

• Manufacturing Support: Collaborate with manufacturing teams to streamline production processes, develop assembly procedures, and ensure quality control throughout the manufacturing lifecycle

• Vendor Collaboration: Work directly with hardware vendors and suppliers to specify requirements, evaluate components, and oversee the integration of third-party hardware solutions

• System Integration: Bridge the gap between hardware capabilities and software requirements, ensuring seamless communication between embedded systems and higher-level autonomy software

• Technical Documentation: Create detailed technical specifications, hardware design documents, and integration guides for internal teams and external partners

• Quality Assurance: Implement rigorous testing protocols for hardware reliability, environmental durability, and compliance with industry standards and regulations

• Strategic Input: Evaluate and communicate the long-term impact of technical decisions on the product roadmap. Proactively identify architectural trade-offs and contribute to the technical direction of the product.

• Embedded Development Experience: Hands-on experience with hardware, microcontrollers, and operating systems for embedded platforms is essential. Experience with Embedded Linux is a significant advantage.

• Drone Technology Expertise: Demonstrated experience with UAV technologies, including flight controllers, communication protocols (e.g., MAVLink), and autopilots (ArduPilot/PX4/etc).

• Technical Proficiency: Expert-level skills in Networking (OSI layers, firewalls, routing), Linux, Shell scripting, Docker, Python, and databases (SQL/NoSQL). Experience with C/C++ and IoT communication protocols is a plus. RF engineering knowledge is also advantageous.

• Development Platform Knowledge: Familiarity with platforms like Raspberry Pi and various flight controllers (e.g., Matek, OrangeCube) used in drone and embedded development.

• Integration Experience: Proven track record of planning, executing, and documenting complex system integrations, particularly involving both hardware and software components.

• Communication Skills: Ability to articulate technical concepts clearly and effectively to both technical and non-technical audiences.

• System-Level Thinking: Deep understanding of how individual hardware and software components impact the entire product and system architecture—not just isolated subsystems. Ability to generate architectural solutions and reason holistically across the full stack.

• Problem-Solving Abilities: Great analytical skills, with a talent for diagnosing and resolving integration issues efficiently.

• Work on meaningful products that protect lives and shape the future of Defense Tech.

• Dynamic environment with the unique opportunity to directly influence and see the impact of your work.

• Lean, ambitious, and strong team.

• Competitive salary, benefits package (insurance, paid sick leave, 20 paid days off per year).

• Benefits of the defense sector (reservation and related benefits).

• Flexible remote work options (possibility to commute to the office if needed is essential).

✔️ Intro Call with TA Specialist → ✔️ Technical Interview (2 parts) → ✔️ Management Interview → ✔️ Offer

Please note that, as a leading defense tech company, we take operations security seriously and may need to perform additional background checks as part of our hiring process. We will do so in accordance with all applicable EU laws and regulations and safeguard your data in the process.
