About the Software Engineer III Position:

As a Software Engineer III at Avalon, you’ll serve as a senior technical contributor within your team, leading the design and development of scalable, high-quality software solutions that support our business goals. You’ll take ownership of complex features and projects, guiding them from concept to delivery while ensuring technical excellence and alignment with team objectives.
