Sr Principal Software Engineer - Common Components

Join a newly formed platform engineering product line at a leading global financial institution, building reusable frameworks, SDKs, tools, and services behind a clean layer of abstraction, so that thousands of engineers across the enterprise build software faster and more securely and stop re-implementing the same authentication, resiliency, observability, and compliance plumbing again and again. Our flagship managed framework is already adopted across tens of thousands of code repositories; our mission is to scale that model from a single widely adopted component to a broad portfolio, each engineered to the same high bar and integrated across the enterprise.

As a Senior Principal Software Engineer on a platform engineering team at a leading global financial institution, you provide deep engineering expertise across agile teams and consistently challenge the status quo. You lead the strategic development behind new and existing components and keep the organization at the forefront of industry trends and technological advances.

AI has reset the clock on how fast large organizations must adapt, and it raises both the stakes and the payoff of getting reuse right. We design our components to be agent-native (consumable by LLMs, agents, and modern developer tooling by default, with living documentation), so the building blocks engineers and agents reach for tomorrow are the ones we create today. This is a chance to work on genuinely hard problems and build solutions that scale across one of the largest technology organizations in the world.

We offer opportunities for career advancement, impactful work using a range of modern technologies, and a supportive, inclusive environment where your ideas matter. Join us to make a difference for our customers and the engineering community.
