Company Arlo Industries is building the sensing infrastructure layer for the drone age. We build distributed passive optical sensing systems for tracking drones and missiles. Our systems combine edge AI, optics, and distributed networking to create persistent aerial awareness without relying on traditional emitting radars. We are a YC-backed defence tech startup operating across the US, Europe, and Ukraine. Role We are looking for an engineer to own the networking and communications layer across our distributed sensing nodes. What you will work on

• Design networking architectures for distributed sensor systems
• Build resilient mesh and hybrid communications infrastructure
• Integrate 5G, sub-GHz mesh protocols, and SATCOM systems
• Develop low-latency node-to-node data pipelines
• Design systems resilient to packet loss, interference, and degraded connectivity
• Work on synchronisation, coordination, and distributed state across nodes
• Participate in field deployments and testing

You are a strong fit if you

• Have built networking systems for constrained hardware
• Understand RF and networking tradeoffs in real deployments
• Have shipped embedded networking or firmware systems
• Think deeply about resilience and failure modes
• Want to work on difficult real-world systems

Bonus

• Tactical networking or defense communications background
• SATCOM experience (Starlink, Iridium, etc.)
• Distributed systems synchronisation experience
• Familiarity with EW or contested RF environments

Compensation

• San Francisco, CA: $150k–250k USD
• Troy, NY: $140k–200k USD
• Helsinki: €85k–140k EUR
• Kyiv: $45k–90k USD
