Procedure

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.

Procedure is hiring for WorkHero.

Across the U.S., thousands of small HVAC businesses are drowning in admin. WorkHero pairs seasoned office managers with AI workflows to free up their time, unlock growth, and modernize the trades. We handle everything that touches the back office of a small HVAC operation: billing, rebates, permits, warranties, marketing, and more. Our customers save dozens of hours every week, allowing them to focus on growing their business.

We are building at the intersection of Human and AI automation, and that’s where you come in!

How you will help us achieve it

As an Applied AI Engineer, you will collaborate with the company founders, product team, and office managers to develop agentic workflows for many of their daily processes. You will ideate, design, implement, and maintain the software side of the product. You will design the UX, develop the front end interfaces, build backend routes and design database models. The bulk of this role is interacting with office managers to understand their workflows and then creating and managing AI agents & workflows to make them more efficient.

In your day to day, you will:

• Partner with our frontline staff to understand their work so you can automate it with AI and save them time
• Live on the cutting edge of Human & AI interactions, keeping up to date with the latest patterns and how they apply to WorkHero and our workflows
• Contribute to exceptional code quality and performance of the code base
• Mentor young engineer(s) to be great at their craft, as our team grows

Key Details

• You can work remotely from anywhere with an overlap of at least four hours with the product team (6 pm to 10 pm IST)
• This role involves participating in calls with US-based stakeholders
• The compensation comes with a salary and an equity component
• Location - Remote
• YOE - 5 to 10 years
• NP - Immediate to 30 days

You’ll thrive if you

• Care about your craft and the mission of the software you are developing
• Are enterprising and can figure out how to convert workflows/playbooks to AI agents
• Work with cutting-edge AI tools and APIs
• Don’t just complete tickets that are assigned to you; you think deeply about the product and how you can make it great, then put that into action
• Enjoy developing 0-1 software products iteratively
• Are proficient in the Typescript ecosystem, including monorepos.
• Are skilled in React and Express (Koa is a plus) or similar tech
• Are pragmatic and understand trade-offs in software engineering

Requirements

• 4+ years of experience in building software products
• Have created applications using AI and LLMs. Can understand when to prompt, use RAG, create agents or fine-tune an LLM
• Have solid experience with the MERN stack
• Ability to debug and optimize complex systems
• Excellent communication and collaboration skills

Bonus points if you have

• Experience in mentoring junior team members. Better if they had gone to replace you in your team, allowing you to take up a more meaningful role
• Familiarity with our tech stack (React, Koa, Mongo, AWS, React Native)
• A good understanding of UX best practices for SaaS based interfaces & AI
• Built apps using React Native
• A deep understanding of infrastructure and can optimize for cost
• Set up evaluation frameworks for agentic workflows
• Contributed to open-source projects

Your First Six Months

• You will be working on creating AI Agents/Workflows based on the playbooks for some of the crucial workflows of HVAC office managers
• You will work on building the frontend, APIs and apply AI knowledge to add features to the office manager and admin portal, as well as the mobile app
• You will be using Vercel AI SDK to create abstracted AI agents and workflows with the capability of falling back to different providers
• You will demo the agentic workflows to US-based stakeholders—small HVAC business owners, product team and office managers
• You will monitor and manage the AI Workflows, ensuring quality and accuracy, improving them over time
