About this role

Geniee, a marketing-technology company, is hiring a Backend Tech Lead for a new AI and marketing SaaS product that combines its existing customer base with the AI technology of its group company JAPAN AI. The product is meant to move value from features to completed work and may later absorb existing businesses.

The lead's main mission is to build and scale an AI-native development organisation and to lead the product's architecture, working with the CTO and the head of engineering on top-level technical decisions. The lead redefines development processes around AI, reviews generated code critically for quality and architecture, and guides junior and mid-level engineers. The stack is TypeScript, GCP Cloud Run, ClickHouse and AlloyDB.

Applicants need server-side development in TypeScript, practical architecture design experience covering scalability, availability and cost, experience building and promoting AI-native development, and Japanese at JLPT N1 level or above for interviews and work. Experience with Cloud Run, ClickHouse or other columnar analytics databases, AlloyDB or PostgreSQL, tech-lead work in a small team, sales or marketing domain knowledge such as CRM and automation, and public technical talks are preferred.
