Senior Full Stack Software Engineer
Senior full stack engineer at Operio (hybrid in Palo Alto) building AI-native operational intelligence for fleet and field service teams. You'll own features end to end — Python/FastAPI backend, PostgreSQL schema, React/Next.js UI — and wire LLM-powered agents (LangGraph/LangChain, LangSmith) into user-facing product features.

Skills
Must have
- 3+ years of software engineering experience shipping production full stack systems
- Expert-level Python: async patterns, type systems, dependency injection, testing, and frameworks such as FastAPI, Pydantic, Django, SQLAlchemy, or Celery
- Strong frontend skills in React and Next.js, including component architecture, state management, data fetching, and performance optimization
- Solid database expertise across relational systems (PostgreSQL preferred), schema design, query optimization, migrations, and ORM usage
- Hands-on familiarity with LLMs, prompt engineering, and agentic AI frameworks (LangChain, LangGraph, or equivalent)
- Experience using LangSmith or comparable LLM observability/evaluation tooling in production
- Comfort with AI-assisted development workflows (Claude Code, GitHub Copilot, or OpenAI Codex)
- Experience managing engineering work in Linear or a comparable sprint-planning tool
- Prior startup experience: operating with limited process, high ambiguity, bias toward shipping
- BS degree or higher in Computer Science, Software Engineering, or a closely related technical field
Nice to have
- Experience with Daytona or similar cloud development environment platforms
- Exposure to data engineering tooling: dbt, Dagster, Airflow, or comparable pipeline orchestration
- Experience with streaming APIs, WebSockets, or real-time data delivery to frontend clients
- Contributions to open-source projects or a portfolio of shipped product work

ABOUT OPERIO
is building AI-native operational intelligence for fleet and field service organizations. Our platform delivers purpose-built AI assistants that help dispatchers, fleet managers, and field teams turn complex operational data into instant, actionable decisions. We are a small, fast-moving founding team in Palo Alto, building products that real operators depend on every day.
THE ROLE
We are looking for a Senior Full Stack Software Engineer to be a core contributor to the Operio AI platform. You will own features from database schema to React UI, with particular depth in Python-based backend systems and AI-integrated workflows. This role sits at the intersection of traditional full stack product engineering and modern agentic AI development—you will be equally comfortable debugging a FastAPI service, designing a database schema, and wiring an LLM-powered agent into a user-facing feature.
You will work in a highly autonomous environment where engineers take end-to-end ownership. Startup experience is essential—we move fast, change direction when the data demands it, and expect everyone to bring both technical rigor and pragmatic judgment to every decision.
WHAT YOU'LL DO
- Design and build full stack features across the Operio platform, from Python/FastAPI/Django backend services to React/Next.js frontend interfaces
- Develop and maintain AI-integrated product features, including LLM-powered workflows, agentic task pipelines, and natural language interfaces for fleet operations
- Architect and optimize relational and document database schemas to support complex operational data models and high-throughput telemetry ingestion
- Integrate and maintain LLM evaluation pipelines using LangSmith to monitor model quality, latency, and regression across production features
- Collaborate with AI engineers to wire multi-agent framework outputs into clean, reliable product surfaces
- Use Daytona for standardized, reproducible cloud development environments across the team
- Manage tasks, sprints, and engineering workflow in Linear, contributing to clear project planning and transparent execution
- Leverage AI-assisted development tools—including Claude Code and OpenAI Codex—to accelerate velocity and maintain high code quality
- Write tests, instrument observability, and participate in code review with a high bar for reliability and maintainability
- Contribute to technical architecture decisions and help shape engineering culture as an early team member
WHAT WE'RE LOOKING FORRequired
- 3+ years of software engineering experience with a proven track record of shipping production full stack systems
