Senior Full-Stack Engineer — AI Ad Tech Ownership

Agentmama AI AB; Stockholms kommun; On-site; SEK 900,000 - 1,200,000; Full time

Job summary

agentmama AI AB in Sweden is seeking a senior engineer to own features end-to-end in a fast-moving TypeScript stack, reporting directly to the CTO. You’ll ship from Prisma schema to React components, delivering customer value within days.

You’ll work on backend NestJS services and tRPC procedures, extend Pub/Sub data pipelines, refine AI audit agents, and keep migrations and access control clean as our product grows.

Qualifications

• 5+ years building production web apps with TypeScript on server and client.
• Strong PostgreSQL schema design, migrations, and performance (Prisma a plus).
• Experience with event-driven or queue-based architectures (Pub/Sub, SQS, Kafka).
• Habit of testing to move faster, not just to follow instructions.
• Pragmatic product sense; shipping focused over perfect abstractions.

Responsibilities

• Design and build features across our TypeScript monorepo — tRPC procedures and NestJS services on the backend, React on the frontend.
• Extend our integration workers that sync data from Google and Meta APIs via Pub/Sub pipelines.
• Work on the AI audit agent: prompt design, rule evaluation, and turning LLM output into reliable actions.
• Help productionize our in-house prediction models and integrate them with the rule engine.
• Evolve the data model in PostgreSQL/Prisma and maintain migrations, multi-tenancy and access control.
• Own quality: write tests, review PRs, and keep CI/CD fast and boring.
