Principal iOS Engineer

As an iOS Team Lead, you are a true project leader. You own the technical direction and delivery of client engagements while multiplying the effectiveness of the engineers around you.

This is a hands-on leadership role. You will design systems, write code when it matters most, guide architectural decisions, and ensure the team delivers high-quality outcomes even when you are not directly contributing code.

You will work closely with client stakeholders, designers, product partners, and Lab49 leadership to ensure solutions are technically sound, aligned with business objectives, and delivered with excellence.

This is an on-site role – 5 days/ week in the WTC area in NYC.

What You'll Be Doing

• Design, implement, deliver, and test innovative iOS Swift applications while understanding our products from both a technical and product perspective in the context of our client’s business.
• Communicate with leadership, product owners, other?technologists?and users to create working software based on an understanding of business and technical priorities.
• Break down complex problems into elegant technical solutions to intelligently solve problems for Lab49's clients.
