AI Engineer

About the RoleWe're a fast-moving, early-stage startup operating in the AI-powered talent acquisition space, and we're hiring AI Engineers to tackle two of our most critical technical challenges: scaling our backend infrastructure and optimizing the LLM and AI agent flows that power our core product. You'll join a small, high-agency engineering team where your work has direct and immediate impact on platform performance and user experience. We're looking to bring on 1–2 exceptionally strong, startup-motivated engineers who are passionate about building reliable, production-grade AI systems. What You'll Do• Take full ownership of backend scalability — design, build, and maintain services and systems that perform reliably at scale. • Tune, iterate on, and optimize LLM integrations and AI agent orchestration pipelines to improve reliability, efficiency, and output quality. • Collaborate closely with a fast-moving team, shipping meaningfully and often. • Contribute to shaping engineering culture and technical direction as an early team member. What We're Looking ForRequirements (dealbreakers): • Based in Stockholm, or legally eligible to work and willing to relocate to Stockholm — no visa sponsorship available. • 5+ years of backend software engineering experience delivering scalable production systems. • Hands-on experience integrating LLMs and optimizing AI agent workflows in live production environments. Required skills & experience: • Strong backend engineering fundamentals — you've built systems that scale and you've felt the pain of when they don't. • Practical experience shipping AI-driven features in production; you understand the nuances of LLM reliability and performance tuning. • Startup experience — you're comfortable with ambiguity, own your work end-to-end, and move fast without waiting for permission. Nice to have: • A strong portfolio of side projects that demonstrates technical depth and sustained curiosity. • Experience building AI-driv
