For over 30 years, Weiss Asset Management has developed proprietary value-based investment strategies designed to deliver high risk-adjusted returns to our investors, who include charitable foundations, pension plans, endowments, hospitals, government entities and private investors. We manage approximately $3.8 billion across hedge funds and institutional accounts. We work collaboratively to solve problems and to identify undervalued assets through deep fundamental research, statistical analysis and an analytically rigorous approach to decision making. Above all else, we value integrity, uncompromising rationality, creativity and entrepreneurship, and continuous learning and improvement. Our team of around 100 individuals is the engine of our success, and we welcome truly exceptional candidates from all backgrounds. WAM is a fit for you if: •You enjoy a collaborative environment, where decisions are made in diverse teams. At WAM, all employees can expect to work directly with members of other departments representing a range of backgrounds. •You work well in a flat structure and are comfortable voicing dissenting opinion. Talent and work ethic will dictate what you can achieve at WAM, as evidenced by the fact that our co-president and the majority of our managing directors began their careers here as interns. •You are driven to constantly learn, improve, and make rational decisions based in fact and data, and you welcome receiving feedback as well as sharing knowledge with others. •You prioritize acting ethically in all situations.

At Cerebelly, we’re turning mealtime into a movement. We call it #missionnutrition, and we’d love to have you and your little ones along for the ride. We spent years rethinking the way we nourish our kids’ minds and bodies. And it isn’t just about food. It’s about inspiring all of us to learn more and ask the right questions about what we feed our children. Our little ones may be on a journey, but we parents are, too. Join us. We can’t change an industry alone. We’re all in this together.
