What You'll Do:

As a Senior Applied AI Engineer at Inversion, you will define and build the company's internal AI tooling strategy from the ground up. You will own the research, development, deployment, and iteration of AI systems that help teams across the company work faster and make better decisions, beginning with software engineering workflows and expanding to broader company-wide use cases. This role is cross-functional and ambiguous by design: you will identify high-leverage opportunities, prototype quickly, harden what works, and help shape what AI-enabled work should look like at Inversion. You will be a key member of the Internal Software Tools team, reporting directly to the Director of Software.
Key Responsibilities:

• Design, build, and deploy internal AI systems and agent-based workflows that unlock useful AI capabilities for teams across the company.
• Own the end-to-end lifecycle of applied AI tools, including problem definition, prototyping, evaluation, deployment, monitoring, iteration, and long-term maintenance.
• Develop agent platforms and supporting infrastructure that can safely and reliably perform tasks such as information retrieval, document analysis, workflow automation, and software development assistance.
• Research and validate technical approaches for internal knowledge access and agent behavior, including retrieval-augmented generation, tool use, prompt architecture, and model evaluation methods.
• Establish best practices for applied AI development at Inversion, including experimentation, evaluation, rollout strategy, observability, and responsible use of AI systems.
• Help define the long-term product and technical vision for how AI tools should be used across the company as Inversion's first AI-focused engineer.

Required Qualifications:

• Direct experience building and deploying applied AI or LLM-powered systems in production or near-production environments.
• Experience working with modern LLM application patterns such as tool use, prompt design, structured outputs, agent workflows, or retrieval-based system
• Strong software engineering fundamentals, including system design, testing, debugging, code quality, and maintainability
• Experience developing backend systems, APIs, internal tools, or automation frameworks
• 5+ years of professional software engineering experience building and shipping production-quality software systems.
• An innovative and optimistic approach to an environment with high ambiguity, shifting priorities, and loosely defined problem spaces.
• Position may require occasional extended hours and/or weekend work.

Desired Qualifications:

• Experience building internal AI assistants, coding agents, workflow automation systems, or knowledge assistants for enterprise or technical teams.
• Experience designing retrieval systems over large internal document sets, including search, indexing, chunking, ranking, metadata strategies, or RAG-style architectures.
• Experience with fine-tuning, model experimentation, or other techniques for adapting foundation models to specific domains or workflows.
• Familiarity with TypeScript/Javascript and full-stack development for internal tools and user-facing AI applications.
• Prior experience in a small team or startup environment where you were expected to define scope, set direction, and execute with a high degree of ownership.
