Communications Engineer (f/m/d)

At the core of Omnisent’s innovation are ultra-low-power sonic devices and the company’s Large Acoustic Model (LAM) — a foundation model trained on the complex world of non-speech audio. This unique combination enables the real-time detection, classification, and localization of acoustic events — whether identifying drones in contested airspace or tracing air leaks in manufacturing systems.

• Architect the RF backbone of a long-lived distributed sensing network for low-power, wide-area acoustic monitoring.
• Design and optimize sub-GHz / LPWAN communication for multi-year battery operation across large distributed deployments.
• Develop robust mesh or hybrid mesh–LPWAN strategies with self-healing, redundancy, and resilience in challenging environments.
• Design and integrate embedded antennas into compact, ruggedized housings, collaborating closely with mechanical and electronics teams.
• Implement interference-tolerant communication techniques suitable for real-world, noisy RF conditions.
• Ensure regulatory compliance with ETSI/FCC/RED and regional spectrum requirements.
• Co-design communication strategies with firmware teams to maximize power efficiency and reliability.
• Lead RF prototyping and validation including lab testing and DFM-focused iteration for smooth production handoff.
• Collaborate with EMS partners on manufacturing, test planning, and quality optimization.
• Conduct real-world RF testing to evaluate range, performance, and environmental impacts.
• Explore emerging LPWAN and sub-GHz technologies to keep Omnisent’s platform at the forefront of innovation.

• Bachelor’s or Master’s degree in Electrical Engineering, Communications Engineering, RF Engineering, or a closely related field.
• 3+ years of experience in RF or wireless communications engineering.
• Hands-on experience with sub-GHz or LPWAN technologies.
• Strong understanding of link budgets, modulation schemes, antennas, and RF propagation.
• Skilled with RF lab tools (spectrum analyzers, VNAs, signal generators, etc.).
• Familiarity with ETSI/RED or FCC frameworks and designing for successful compliance testing.
• Comfortable collaborating cross-functionally with firmware, electronics, mechanical, and cloud teams.
• Strong communication skills in English (German a plus).
• EU work authorization.

• Experience taking RF systems from prototype to field deployment.
• Background in interference mitigation or robust communication techniques.
• Experience with DFM, DFT, and EMS collaboration.
• Background in mission-critical systems or industrial-grade platforms.
• Startup experience and a desire to help build something truly groundbreaking.
