Diopter is a real-time defense for people in live conversations. We watch phone calls and video meetings as they happen, with email coming next, for a cloned voice, a fake face, and the pressure an attacker applies to rush someone into a decision.

Instead of checking whether one clip is fake, we follow the whole conversation and compare where it is heading against the rules a company already has for approving money, hiring, and access. When something is off, the person on the call gets a explicit warning and a next step while there is still time to stop. We are building this now because AI is about to let a small number of attackers run these conversations at a volume no human team can keep pace with, and the human layer is the part of a company nobody has protected yet.

About the Role
We're hiring a Principal Software Engineer to build the foundation that the rest of Diopter's technology runs on. You'll design and ship the high-throughput media streaming pipelines, the backend services, and the customer-facing frontend that together make up our platform.



You'll also make sure it deploys cleanly and securely into our cloud and into customer data centers.
This is a hands-on, full-stack principal role. You'll set the architecture, write a lot of the code, and hold the bar for how everyone else builds on top of it. Since we're a security company, you'll treat every design decision as a security decision.

What You'll Do
• Own the core platform architecture, from design through rollout to long-term operation:
• Real-time media pipelines: ingest, transport, chunking, buffering, and fan-out of live audio and video streams (meetings, calls, uploads) with predictable latency and backpressure under load.
• Backend services: high-concurrency APIs and processing services in Go and Python, including job orchestration, queueing, deadlines, retries, and idempotency.
• Frontend: the customer dashboard, admin console, and integration surfaces, built in TypeScript and React to be fas
