Software Engineer

Generalist software engineer building and maintaining platform APIs, infrastructure, and real-time streaming systems for voice AI models at a startup. Requires 5+ years experience and strong backend fundamentals.

About the job

What You'll Own

Platform APIs: authentication, billing, account management, and the surface that keeps the business running.
Feature work across the stack — supporting the rollout of the next generation of our TTS and end-to-end speech models.
Integration and migration work as Rime evolves: token-based authentication, new billing and metering providers.
Maintenance and hardening of the current TTS API stack and assisting in its evolution.
Realtime, low-latency, horizontally scalable streaming speech infrastructure.

What We're Looking For

5+ years of IC engineering experience with strong backend fundamentals.
Experience with at least one low level language: C++, Rust, Go.
Systems-level thinking: you understand what's happening at the network, storage, and runtime layers, not just the application layer.
You build clean interfaces and design for loose coupling; you don't create systems only you can debug. Bias towards codification and reproducibility.
Comfortable moving through an unfamiliar codebase and shipping without extensive hand-holding.
Strong async written communication — we're global and the written word is how work gets done.

Bonus Points

Experience integrating 3rd party API’s, such as payments, monitoring, and CRMs.
Experience with gRPC or other bidirectional binary streaming protocols.
Experience with multilingual monorepos where you pick the best language out of merit more than personal experience.
Experience with cloud infrastructure.
Experience at a small startup where the scope of your role was broad and undefined.
Comfort working within ML systems.
