Sr. Full-Stack Developer

At Valley Bank, we believe in people's growth potential. We invest in it. We protect it. We focus it. For nearly 100 years, we've been the Bank that clients from every industry turn to for our expertise, strategies, and advice--building the kind of trust that can fuel every goal. We are the leading relationship bank built for growth--with over $60 billion in assets, 3,800 experts, and more than 200 consumer branches and commercial banking offices in communities across the US.

At Valley, we're all driven by an ambition that goes deeper than just having a job. That's why when you work for us, we make it our goal to help you focus on what drives you--working to turn your passions and strengths into assets you can use to propel your ambitions and build the professional legacy you want. Because when we say we're a relationship bank built for growth, that's not just reserved for our clients--that includes all our associates as well.

We are looking for a fast-moving Senior Full Stack Developer who views AI-assisted development as a baseline capability rather than a novelty. You will be responsible for designing and building secure modern applications supporting commercial and consumer banking capabilities, integrating with existing and emerging architecture, data platforms, and digital channels, leveraging cloud and AI-enabled technologies for the full software development lifecycle..
