Role overview
A fast-growing, seed-stage B2B SaaS startup in the productivity and AI communication space is looking for a Founding AI Engineer to join its founding team. You'll help build an AI-native email and meetings product — rethought from the ground up — that understands relationships, takes meeting notes in the background, and drafts context-aware follow-ups in your tone. This is a high-ownership, high-impact role where you'll shape both the technical foundation and the product direction from day one.
Responsibilities
- Design and implement LLM flows for context engineering, prompt design, and tool integrations to power intelligent email experiences.
- Build and optimize cloud infrastructure (GCP) for scalability, performance, and reliability.
- Develop and maintain a custom sync engine engineered for near-instant responsiveness.
- Execute database migrations, performance tuning, and product-focused changes based on highest-impact priorities.
- Iterate rapidly on prototypes and production features to surface relevant user actions and cut through inbox noise.
- Operate as a founding team member — own the most critical problems regardless of domain.
- Contribute to hiring and help grow the team thoughtfully.
- 5+ years of hands-on experience as a software or AI engineer delivering production AI-enabled applications.
- Based in Stockholm, Sweden or willing to relocate and work on-site.
- Proven experience building AI-powered features using Large Language Models (LLMs), including context engineering and tool integration, in production.
- Experience deploying AI workloads in production cloud environments with monitoring, reliability, and scalability.
- Experience with data pipelines and integrations to support AI features.
- Experience building and shipping production-grade full-stack web applications (frontend and backend) with emphasis on performance and scalability.
- Proficiency with Git, CI/CD practices for AI-enabled software.
- Experience with ML model development, training, evaluation, and deployment in production.
Preferred qualifications
- Strong portfolio of side projects demonstrating AI/ML or related engineering depth.
- Prior fast-paced startup experience or proven ability to operate with high ownership in a rapidly changing environment.
- Founding mentality: comfort with ambiguity, ultra-high ownership, and flexibility across domains.
Benefits
- Salary range: $80,000 – $120,000 USD annually.
- Visa sponsorship available.
