Backend / Infra Engineer

You might be a fit if you

• Have senior/staff experience running distributed backends with real-time/streaming constraints.
• Are fluent in TypeScript/Node.js and comfortable jumping into Python for ML/audio jobs.
• Know Temporal (or similar workflow engines), queues, Redis, and PostgreSQL.
• Have shipped production LLM apps and understand prompt/tool design, evals, and guardrail instrumentation.
• Operate cloud-native on AWS with Terraform; k8s doesn’t scare you.
• Are a power user of Cursor/Zed/Devin and were using code-gen before it was cool.
• Have intuition for what current-gen LLMs can/can’t do—and what tomorrow’s models will unlock.
• Think independently, grind with customers, and do whatever it takes—without dropping the quality bar.
• Bonus: built 0→1 real-time systems in Telecom/Networking, Autonomous Vehicles, or HFT; founded something; built AI voice apps.

Interesting problems you’ll touch

• Voice simulations that feel real: accents, overlapping speech, crosstalk, background noise, barge-ins.
• Massive concurrency: 10,000+ parallel calls with deterministic behavior and graceful degradation.
• Temporal-driven orchestration for long-running, interruptible call flows.
• Closed-loop reliability: turn prod failures into auto-generated tests and blocked deploys.
• Trace-everything culture: make “what happened?” a 30-second question, not a war room.

How we work

• Outcomes over output: we adjust roadmaps when new data lands.
• Demo early and document decisions so context moves fast.
• Own incidents: lead the investigation, write crisp notes, land durable fixes.
• Direct, candid, respectful communication keeps remote teammates in lockstep with Austin HQ.

Our stack

• App: Next.js, TypeScript, Tailwind
• AI: OpenAI, Anthropic, STT/TTS providers
• Realtime/Orchestration: LiveKit, Pipecat/Daily, Temporal
• Infra/DB: AWS, k8s, PostgreSQL, Redis, Terraform
• Observability: OpenTelemetry, SigNoz
