At Lab49, engineers work directly with clients to design and deliver production systems. We combine technology, design, and business expertise to solve real problems where quality, performance, and clarity matter.
LAB49 is currently looking for an iOS Senior Associate who will play a critical role on key projects for Lab49 clients. Working in a collaborative and innovative project team, with direct client-facing interactions, you will have an opportunity to apply your skills and expertise to design innovative applications that solve complex problems and enhance performance and productivity at our marquis clients. In particular, you will help build and modernize large-scale consumer banking experiences, focusing on areas such as customer onboarding, account management, and money movement. As part of a greenfield initiative, you will lead the development of new mobile capabilities designed to support expansion into new markets and evolving regulatory requirements.
THE ROLE
As an iOS Senior Associate, 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.
- Actively contribute to the adoption of strong software architecture, development best practices and new technologies. We are always improving the process of building software; we’ll need your help to do that.
- Bring a passion to stay on top of tech trends.
- Experiment with and learn new technologies.
What Success Looks Like
- Your teams consistently deliver high-quality software that meets user and client objectives.
- Engineers around you become more autonomous, capable, and effective because of your leadership.
- Clients trust your judgment and rely on you for technical direction and clarity.
- You demonstrate strong ownership of outcomes, proactively addressing risks before they become issues.
- You can step away from day-to-day coding when needed without compromising delivery quality or team performance.
In your first 6 to 12 months, success means:
