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

Team Leadership & Leverage * Lead and mentor engineers across one or more workstreams, helping them grow technically and professionally. * Delegate effectively, manage priorities, and create clarity so the team can execute with confidence. * Foster a culture of ownership, accountability, and continuous improvement. * Serve as a role model for how to think, communicate, and act as a senior consultant and engineer.

WHAT YOU SHOULD HAVE * 10+ years of experience designing and building complex, commercial‑grade software systems. * Proven track record of leading and driving the UI development stream for large-scale, multi-year greenfield projects from conception to deployment. * Deep expertise in JavaScript and TypeScript, with one or more modern UI frameworks (React, Angular, Vue, etc.). * Strong understanding of end‑to‑end web application architecture, APIs, data flow, and performance considerations. * Experience with AI/LLM tooling, automation frameworks, or engineering agents * Solid grasp of SDLC practices, CI/CD, automated testing strategies, and quality management. * Strong professional experience within banking, payments, or financial services * Excellent communication skills and the ability to influence technical and non‑technical stakeholders.
