The Role
Own the end-to-end real-time voice and data platforms, including AI agents for live calls, telephony and streaming integrations, call-data pipelines, analytics, dashboards, monitoring, and cloud infrastructure. Build AI workflows, product interfaces, and business automations; optimize latency, cost, reliability, and performance; respond to production issues; and mentor teammates while collaborating with product and domain experts.

Procedure is hiring for WorkHero.
WorkHero is building the AI-powered back office for the skilled trades, starting with the $50B+ HVAC industry. Small contractors are great at their trade but lose 20+ hours a week to invoicing, permits, scheduling, and paperwork. WorkHero combines expert office managers with automation and AI tooling, enabling a small team to take real ownership of that back-office work
We’re hiring a senior engineer to own our real-time voice stack end to end—AI agents operating on live phone calls—and the data platform that turns those calls into insight: call → transcript → events → warehouse → dashboards. You’ll own meaningful systems end to end alongside a small, senior team with deep experience in AI, product, and the trades.
What you’ll build
- New product screens and flows (jobs, customers, invoices, scheduling) in React and React Native, especially AI chat UI (chat & tool result rendering, streaming responses, human review and feedback loops)
- AI workflows in production: tool-using agents, RAG/search, classification/extraction, and human-in-the-loop flows
- Automations: Contribute new features and improvements to our AI-powered business automation platform
In addition, you’ll own our first investments into a realtime voice stack and the call-data platform behind it. For example:
- Realtime voice agents on live phone calls: telephony/WebRTC integration, streaming speech-to-text and text-to-speech, turn-taking, interruption handling, and latency optimization
- Voice pipeline reliability: backpressure, failover, graceful degradation, and monitoring for live calls
- Call-data pipeline: transcripts, events, and structured extraction flowing from every call into the warehouse
- Analytics & dashboards: data modeling and conversation-intelligence features on top of call data
- Evals & monitoring for voice agents: quality metrics, drift detection, and cost/latency tracking
- Cloud infrastructure: scaling our platform with infrastructure as code, queues and orchestration, and CI/CD
Responsibilities
- Analyze requirements and propose innovative AI-native solutions to technical problems
- Write clean scalable code
- Own the voice and data stack end-to-end: design, build, test, deploy, and operate
- Optimize the performance, latency, and cost of our real-time AI systems
- Respond to critical system issues and ensure continuous system reliability
- Mentor team members and collaborate across teams, especially with product and subject matter experts
- Work to understand the needs of our users and think creatively about how to solve design challenges in your work
- This is a Remote role. We expect a minimum 4 hours overlap with the WorkHero team (11 AM - 3 PM ET).
Qualifications
- Senior-level backend experience (typically 5+ years) shipping production systems that you've owned
- Hands-on experience with realtime voice or streaming systems: telephony (SIP/Twilio), WebRTC, streaming STT/TTS, or frameworks like LiveKit or Pipecat — or comparable experience with demanding realtime/streaming infrastructure
- Data engineering fundamentals: event pipelines, data modeling, warehousing, and analytics on production data
- Strong proficiency in a typed backend language (TypeScript preferred; comparable experience welcome)
- Hands-on experience with LLM-powered features (usage, prompting, optimization, etc) and AI architectures
- The ability to work with infrastructure as code (terraform), cloud, and CI/CD systems at scale. We're a small team, so we own the whole stack!
- Excitement to leverage AI coding tools to their maximum benefit. We love Claude Code and Cursor and are constantly looking for better ways to leverage our time to build fast and build for scale.
Nice to have
- experience with voice-AI platforms (Vapi, Retell, Bland, Deepgram, LiveKit) or conversation-intelligence products (e.g. Gong-style analytics)
- experience scaling cloud infrastructure, especially AWS, and how to get the most out of key AWS services
- experience with workflow automation tools like n8n or Lindy
- experience with React for building internal dashboards
- experience with HVAC or back-office business workflows
WorkHero is committed to building a diverse team. We encourage candidates from all backgrounds to apply.
Skills Required
- At least 5 years of senior-level backend experience shipping and owning production systems
