Are you brave, passionate, and eager to explore HR and finance tasks? Are you a team player and an inspiring colleague? Join us as an intern in our HR and finance teams! Castrén & Snellman is an internationally operating law firm combining top legal expertise, business understanding, and technology to give clients a competitive edge. We are pioneers in demanding legal services in corporate transactions, dispute resolution, and all other areas of business law. We stand firmly by our clients, offering them a lasting advantage. We are looking for a full-time (37.5 h/week) intern to support our HR and finance teams. The internship begins around late summer or early autumn 2026 and ends in September 2027. At Castrén & Snellman, you can be your authentic self and join a community united by a passion for work. We put ourselves boldly on the line for our clients and team. The busy and demanding everyday life runs smoothly when we help each other. As an intern in our HR and finance teams, you will learn broadly about HR and financial management tasks in a supportive and professional environment. You will develop your organizational, teamwork, communication, and presentation skills. You will coordinate onboarding programs for new employees. You will handle purchase and expense invoices and assist the finance team with various tasks. You will support employment-related matters such as recruitment processes. You will process project-related expenses and assist with invoicing entries. You will act as the main user of our online learning platform and prepare internal surveys. You will coordinate courses with universities and assist in internal training events. We offer good onboarding, benefits, and above all, support and flexibility to make your daily work smooth. Most tasks are performed at our office, as some require presence, but remote work can be arranged separately. We expect you to be in the final stages of your studies or a recent graduate in a commercial or other relevant field, genuinely interested in HR and finance tasks. You work carefully, proactively, and have good organizational skills. You are a flexible team player and can work independently. You enjoy routine tasks but are motivated by new ideas. You are enthusiastic about everyday encounters, have good interaction skills, and a positive customer service attitude. You master Finnish and English excellently; other languages are a plus. You are comfortable using office programs (e.g., Microsoft Office). The internship role suits someone with no previous experience but a strong desire to learn. We value your individuality.

The HR team manages recruitment, employee development, and employment matters; the finance team handles payroll, invoicing, accounting, and internal finance. During the internship, you will have personal tutors from both teams, your supervisor Outi from HR, and teams where you can shine. Welcome to Castrén & Snellman! Apply now!
