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.
