Job description

Senior Software Engineer - AI Agent

Senior Software Engineer - AI Agent: help build AI-powered education workflows, own backend infrastructure, and ship scalable, user-focused tools for students worldwide.

The Role

Build the core product and system architecture for a next‑gen education agent. Design and ship agentic workflows across planning, tool use, memory, evals, feedback loops, and production operations. Own difficult engineering problems end to end, from prototype to production. Build robust backend and infra foundations for AI‑native products. Work across the stack when needed, but go deep on backend systems and infrastructure. Partner closely with product and design to turn ambiguous ideas into working products fast. Push the team toward higher engineering leverage, better abstractions, and faster iteration loops.

Required Skills and Experience

• Hardcore technical ability
• Strong full‑stack skills, especially deep experience in backend and infrastructure engineering
• A 10x builder – able to make sharp tradeoffs and execute fast without lowering the bar
• Strong product instinct, not just implementation ability
• Comfortable operating in ambiguity and moving with very high ownership
• Deep curiosity about AI agents, developer tooling, evals, orchestration, and how modern engineering is changing
• Real excitement for exploring and applying Harness Engineering, not just reading about it

Preferred Experience

• Experience building AI agents, copilot‑style products, workflows, or internal automation systems
• Experience with LLM application infrastructure, eval systems, retrieval, tool execution, or observability
• Experience building developer platforms, infra products, or backend‑heavy systems at scale
• Startup experience, especially 0‑to‑1 product building
• Interest in education, learning systems, or personalized AI products

Benefits

• Rapidly growing start‑up with flexible environment
• Internal promotion opportunities
• $1,000 individual training budget per year
• Psychologist on staff
• Insightful fireside chats and workshops
• Radical Candor culture
• Global presence with remote options
