AI Engineer

About the Role

This is a hands-on engineering role at an early-stage, Y Combinator–backed AI productivity startup. You'll tackle two core challenges: building backend systems that scale and optimising the LLM and AI agent flows that power the product. Your work will have a direct and visible impact on platform performance and the end-user experience.

What You'll Do

• Own backend scalability — design and implement services and infrastructure built to handle growth.

• Tune and iterate on LLM integrations and AI agent orchestration pipelines to improve reliability and efficiency in production.

• Ship software continuously, maintaining a high ownership mindset in a fast-moving, small team.

What We're Looking For

• 5+ years of backend software engineering experience delivering scalable, production-grade systems.

• Hands-on experience integrating LLMs and optimising AI agent workflows in live production environments.

• A practical, portfolio-driven approach — demonstrable side projects and shipped software are valued over formal credentials alone.

• Experience thriving at fast-growing startups; high agency and genuine startup motivation are essential.

• Strong sense of ownership, intentional career choices, and a sustained curiosity for the craft.

• Based in Stockholm or able to legally work and relocate there — visa sponsorship is not available.

Compensation & Benefits

• Salary range: $80,000–$120,000 USD annually, with flexibility for exceptionally senior candidates.

• Equity offered; the salary/equity mix is negotiable.

• Visa sponsorship: not available.

Location

On-site in Stockholm, Sweden.
