About the role

We are looking for a Senior AI Engineer to design, build, and ship AI-powered software across the full stack - from the agentic infrastructure that powers our robot operations, to the backend services that expose it, to the interfaces that operators and engineers use every day. You will own AI features end-to-end: from system design through implementation, deployment, and production monitoring. You understand the failure modes of LLM-based systems - non-determinism, prompt injection, runaway tool-calling, token cost spirals - and you build guardrails that prevent them. You are equally comfortable writing agent orchestration logic, designing REST APIs, and shipping a React dashboard. This is not a research role. We want engineers who have closed the loop from prototype to production with AI systems that real users depend on.

Responsibilities

  • AI Agent Development
  • Design, implement, and deploy production-grade AI agents: multi-step reasoning pipelines, tool-calling workflows, multi-agent coordination, and human-in-the-loop handoffs
  • Design and build agent harnesses - the runtime infrastructure (context management, tool definitions, memory, feedback loops, observability, and lifecycle control) that makes agents reliable in production; the model is a component, the harness is the product
  • Engineer context pipelines: dynamic retrieval, re-ranking, semantic search, and GraphRAG as tools within an agentic reasoning loop - not static RAG pipelines; understand when to retrieve, when to use long context, and when to use agent memory
  • Implement production-grade reliability: retry logic with backoff, cost controls, structured output validation, sandboxed tool execution, and checkpoint-resume for long-running agent workflows
  • Develop systematic evaluation frameworks (evals, golden datasets, regression suites, observability traces) that measure agent quality and catch regressions before production
  • Backend & Infrastructure
  • Architect and implement scalable backend services and APIs (REST/GraphQL) in Go, Rust, or TypeScript/Node.js
  • Build and maintain integrations with external systems - databases, internal APIs, robot data streams - enabling agents to take real actions with appropriate access controls
  • Own deployment, monitoring, and observability: Docker, Kubernetes, CI/CD pipelines, and LLM-specific tracing and cost tracking
  • Frontend & Product
  • Build clean, functional web interfaces in React/Next.js - operator dashboards for robot fleet management, engineering tooling for the AI team, and customer-facing applications
  • Own features end-to-end: product requirements, implementation, testing, rollout, and ongoing maintenance
  • Treat prompt engineering as a first-class engineering discipline: write, test, and version prompts with the same rigor as application code

Requirements

  • Software Engineering Foundation
  • 5+ years of professional software engineering experience with a full-stack production track record - this is a software engineering role first; strong fundamentals in system design, data structures, algorithms, and code quality are required
  • Strong command of Python and/or TypeScript at a production level: clean abstractions, testable code, performance awareness, and maintainability - not just scripting
  • Backend engineering depth: Go, Rust, or TypeScript/Node.js for production services - RESTful and GraphQL API design, relational database modeling (PostgreSQL), async programming, caching, and system integration via APIs and webhooks; Python for AI/ML integration and scripting
  • Frontend engineering proficiency: React, Next.js, TypeScript - able to architect and ship functional, production-grade UIs, not just wire up component libraries
  • Software delivery practices: automated testing (unit, integration, end-to-end), CI/CD pipelines, code review, and observability (logging, metrics, alerting)
  • Containerization and deployment: Docker, Kubernetes - able to own a service from code to production without a DevOps handoff
  • AI & Agent Engineering
  • Proven, hands-on experience building and deploying LLM-powered systems or AI agents in production - beyond prototypes; you understand the real failure modes (non-determin

Additional Information

Dexmate is building the foundation for physical AI - a unified platform that combines high-quality robotic hardware with a universal Physical AI OS, making robots as easy to build and deploy as software. Today, robotics is fragmented, slow, and closed: most builders are forced to reinvent the same stack again and again, and most ideas never make it past the prototype stage. We exist to change that. Our mission is to democratize robotics by lowering the barrier to entry, delivering a plug-and-play platform for developers, researchers, and enterprises, and cultivating an open ecosystem that accelerates the evolution of physical AI. If you want to help shape the next layer of human capability - and believe the future of robotics should be built together, not in isolation - we'd love to build it with you.
