Crimson Education is the world’s leading college admissions consulting firm, with over 1,490 Ivy League offers and 2,410 to the US Top 15. We help ambitious students gain admission to the world’s top universities through expert-led guidance and proven, data-driven strategies. Crimson students are 7x more likely to get into the Ivy League than their peers. We were recently featured on the front page of the Wall Street Journal.

Crimson is the only college admissions consultancy that brings together:

• Former Ivy League and Top 20 admissions officers to rigorously review and refine applications

• Professors and PhD teaching fellows from leading universities to guide students through original, independent research — with pathways to selective peer-reviewed publication or conference presentation

• Past ISEF winners and judges who coach students to compete for state, national, and international science fair awards

• Capstone project mentors who help students design and scale leadership initiatives with real-world impact, measurable outcomes, and credible external validation

We’re backed by leading VC firms, including Tiger Global, Heal Partners, IceHouse Ventures, and Movac, and recently closed a USD $40M Series D funding round at a USD $640M valuation. We now operate across 21 markets worldwide, including the US, Canada, UK, Singapore, Japan, Hong Kong, Australia, and New Zealand.

The Role

What are the main responsibilities for this 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
  

What skills and experience are required?

• Hardcore technical ability

• Strong full-stack skills, with especially deep experience in backend and infrastructure engineering

• The kind of engineer people describe as a 10x builder

• Strong product instinct, not just implementation ability

• Comfortable operating in ambiguity and moving with very high ownership

• Able to design clean systems, make sharp tradeoffs, and execute fast without lowering the bar

• 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

Strong Plus If You Have

• 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
