Principal Tech Lead (C#), Boston

Lab49 is an award-winning specialist consultancy that builds bespoke technology in partnership with the most important companies in global finance. Founded in 2002 to bring Silicon Valley–style engineering to Wall Street, we have helped clients navigate successive waves of technological change - from distributed computing and high-speed automation to enterprise UX, digital distribution, DevOps, cloud, and data science. Today, we are an established partner in financial markets, having delivered hundreds of projects for tier-one investment banks and many of the world’s largest buy-side firms. Joining Lab49 means applying your engineering expertise in an environment where your contributions have real impact. Our engineers work in cross-functional teams, consult directly with clients, and deliver modern software into production. The Principal Tech Lead will play a critical leadership role on a strategic new initiative for a major Lab49 client. You’ll work in a collaborative, client-facing team to lead backend engineering efforts, design robust systems, and guide the delivery of modern digital products for buy-side research analysts and portfolio managers. You will report to the Practice Head and partner closely with Product, UX, and Engineering stakeholders on both the Lab49 and client side to shape the discovery, architecture, and build phases of this initiative.
