WorkHero is building the AI-powered back office for the skilled trades, starting with the $50B+ HVAC industry. We have exciting traction and just closed a $5M seed round to expand our engineering and product organization, as well as add additional services. We’re looking for a senior engineer to own and evolve the backend and AI systems that power our core workflows.
What you’ll buildYou’ll work on a mix of classic backend and AI product infrastructure. For example:
Integrations & ingestion: pull data from third-party systems (APIs/webhooks/files)
AI workflows in production: tool-using agents, RAG/search, classification/extraction, and human-in-the-loop flows
Evals & monitoring: regression tests for prompts/workflows, quality metrics, drift detection, and cost/latency tracking
Scalable systems: queues and orchestration, retries, data modeling, and API design to support rapid product iteration
Security & privacy: strong auth controls and safe handling of sensitive customer data
Analyze requirements and propose innovative AI-native solutions to technical problems
Write clean scalable code
Test and deploy features & services
Optimize the performance of our 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

Senior-level backend experience (typically 5+ years) shipping production systems that you’ve owned
Strong proficiency in a typed backend language (TypeScript preferred; comparable experience welcome)
Hands-on experience with LLM-powered features (usage, prompting, optimization, etc), AI frameworks (Langchain, etc), and AI architectures (RAG, reranking, etc)
The ability to work with infrastructure as code (terraform), cloud, and CI/CD systems. We’re a small team, so we own the whole stack!
A deep understanding of a modern web and AI stack: Cloud, database, API, LLM, and web
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.
