Orbio is an AI-native human capital management platform building a

Digital Workforce for HR

.
We design and deploy agentic systems that take ownership of operational execution across hiring, onboarding, and employee operations — while keeping humans in control.
We work with large, complex organizations across staffing, retail, hospitality, and healthcare. Our customers rely on Orbio to reduce operational friction, improve speed and quality, and scale their teams without proportional headcount growth.
Orbio is not a system of record. We sit on top of existing HR systems and own the

execution and coordination layer

— where day-to-day work actually happens.
Position Overview

Orbio is looking for an

AI Agent Engineer

to build, operate, and continuously improve the reliability of our agentic AI systems in production.
In this role, you will focus on how agents

behave, decide, fail, recover, and scale

in real enterprise environments. Your work will ensure that LLM-powered agents are observable, testable, cost-efficient, and trustworthy when handling real operational workflows.
You will help build an end-to-end, production-grade B2B platform with a strong focus on LLMs, autonomous agents, and conversational AI, contributing to the technical foundations that scale across customers and use cases.
All the desired Technical Skills we are looking for

Agent Testing & Evaluation
Building agent evaluation pipelines (consistency, accuracy, reliability)
Designing test harnesses for non-deterministic systems
Regression testing for prompt and model changes
Synthetic data generation for agent testing
Performance benchmarking and latency profiling
Agent Monitoring & Operations at Scale




Observability for agent systems (tracing, logging, metrics)
Cost tracking and optimization across model calls
Alerting on agent failures, hallucinations, and degraded performance
Debugging complex multi-step agent behaviors in production
Guardrails, safety layers, and graceful degradation strategies
LLM Expertise
Prompt engineering, chaining, and caching strategies
RAG pipelines and vector databases
Model selection, fine-tuning, and cost optimization
Understanding of evaluation metrics and benchmarks
Python & Backend
Async programming, Django/Channels, real-time ASGI
Production-grade application development
Message queues (Celery + Redis) and high-throughput systems
Testing, logging, and performance optimization
Conversational AI
Voice pipelines: STT, TTS, turn-taking, interruption handling
Telephony integration (Twilio) with latency optimization
Conversation flow design and fallback strategies
Full-Stack & DevOps
Frontend experience (React preferred)
CI/CD pipelines and cloud deployment (AWS/GCP)
Deploying and operating AI systems in production
What Success Looks Like at Orbio

Agents behave consistently and predictably across customers and workflows
Failures, edge cases, and degraded behavior are detectable and recoverable
Agent performance, latency, and cost are measurable and actively optimized
New agent capabilities ship safely without breaking existing behavior
Customer trust in autonomous workflows increases over time
Culture at Orbio

Orbio is a high-bar, high-intensity environment. We optimize for impact, speed, and ownership — not comfort.
We operate as one team, with a flat structure and extreme ownership. We ship fast, learn from production, and challenge each other directly because we care about building systems that hold up under real-world complexity. Titles matter less than outcomes. Customers come first. xqbhyrx Momentum matters.
