AI Engineer

About the role

About the Role We'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 For Requirements (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-driven features in a consumer or marketplace product context. Background in fast-growing early-stage startups (pre-seed through Series A/B). We value demonstrated ownership and high agency over formal credentials. A track record of consistently shipping software over time matters more to us than where you studied. Compensation & Benefits Salary: $80,000 – $120,000 USD (with flexibility for exceptionally senior candidates) Equity: Included; salary/equity mix is negotiable Location Stockholm, Sweden — on-site Candidates must be eligible to work in Sweden; visa sponsorship is not available
