Lead full technical stack development and set architectural direction for AI platform with real-time voice and cloud infrastructure. | Staff-level engineer with 4+ years in production systems, deep cloud infrastructure expertise, proficiency in Python, FastAPI, TypeScript, and preferably voice AI or telephony experience. | The Role: You own the stack and set technical direction alongside the founders. You have a real say in the big architectural decisions, and what you ship reaches real users quickly. Perform well and you're on track to Lead Engineer. Responsibilities: Own features end to end across frontend, backend, and the infrastructure they run on. Build and scale our AI employees platform: the application, the FastAPI services, and the data flows that connect them. Run our cloud and telephony backbone on GCP and Kubernetes, keeping production reliable and low-latency as we grow. Lead our real-time voice work and own its hardest challenges: pushing the voice to be the most realistic, driving down latency, and expanding what our AI employee platform can do. Set technical direction with the founders and raise the engineering bar as the team grows. Requirements: You own systems end to end, you have deep cloud infrastructure experience at the staff level, and you use AI in your own work every day. You don't need deep voice, telecom, and applied AI all on day one. Our stack is Python and FastAPI on the backend, GCP and Kubernetes for infrastructure, a modern TypeScript frontend, and real-time media on top. You should be comfortable across most of it and strong in at least one layer. Great to Have: Experience at a voice AI, speech, or telephony company (TTS, STT, SIP, VoIP, latency optimization), or running Kubernetes in production at an early-stage company. Ideal Profiles: Staff or senior full-stack engineer with 4+ years shipping production systems, who has owned cloud infrastructure at scale, ideally with voice, SMS, or real-time media experience. Engineer building with applied AI beyond prompt engineering (speech models, ML pipelines, real-time inference) who wants to do it full time. Engineer from a voice, telephony, or legal-tech company who already knows the real-time stack and the integration landscape.

Provide bilingual technical support by triaging and resolving issues across phone, email, and SMS workflows, debugging full stack using logs and APIs to improve product quality. | Requires 2+ years technical customer-facing experience, proficiency in Python, full fluency in English and Spanish, and comfort with APIs, SQL, and logs. | The Role: You are the technical front line for our AI employees in production. You debug real issues across the stack, talk directly to firms and their clients in English and Spanish, and turn what you learn into fixes and product improvements. Your work is visible to the founders and reaches real users immediately. Responsibilities: • Own support for our AI employees in production: triage, reproduce, and resolve issues across phone, email, and SMS workflows. • Debug across the stack: read logs, query APIs, write scripts, and trace calls through our FastAPI services, escalating true platform bugs with clear, reproducible reports. • Provide bilingual support (Spanish and English) to firms and the clients our AI employees speak with. • Configure and tune AI employees per firm: intake scripts, routing, case-management integrations, and Spanish-language conversation quality. • Build tools, runbooks, and automations that make support faster and turn recurring issues into permanent fixes, feeding patterns back to product. Requirements: • Support or solutions engineer with 2+ years in a technical, customer-facing role who can code (Python or similar). • Fully fluent in Spanish and English, written and spoken, supporting both clients and internal teams in either language. • Comfortable with APIs, logs, SQL, and the command line; bonus for telephony, SMS, or real-time voice experience. • Background in legal tech, a law firm, or another regulated, client-heavy environment is a plus. Who You Are: You are technical and hands-on, fluent in both Spanish and English, and you like solving problems for real people. You can read code and write scripts to investigate issues, and you stay calm and clear when a firm needs help fast. Our stack is Python and FastAPI, GCP and Kubernetes, a modern TypeScript frontend, and real-time media on top. You don't need to master all of it, but you should be comfortable reading code, calling APIs, and digging into logs to find root cause.
