Lead Full Stack Engineer

HYBRID MODEL - 3 Days Onsite - 2 Days Remote - Dallas, Charlotte, or Baltimore,MD

Role Overview

• seeking a Lead Full Stack Engineer to support our client’s telecom and contact center modernization initiative.
• This role will act as the onshore technical lead, working in a hybrid capacity and coordinating closely with both OneMain’s internal team and a dedicated offshore development team based in India.
• The primary focus is accelerating the migration from a legacy Avaya platform to NICE (CXone), enabling new 2-way SMS and converged communications capabilities under aggressive timelines.

Key Responsibilities

• Serve as the hands-on technical lead for a fast-moving, high-visibility telecom modernization effort
• Drive development across front-end, back-end, and API layers, with strong DevOps awareness
• Lead and unblock offshore engineers; provide technical direction without heavy handholding
• Partner with Product and Agile PMs to iterate quickly and deliver incremental value
• Troubleshoot complex, production-impacting issues (“firefighting” when required)
• Ensure engineering execution does not become a bottleneck to program milestones
• Support integration of NICE CXone with downstream and legacy systems, including but not limited to IBM Z-series mainframes
• Maintain high standards for code quality, testing, and operational readiness

Technical Environment

• Frontend: Angular 17, TypeScript
• Backend: GraphQL (Apollo Graph Router implemented at client), API development
• Cloud: AWS-native stack
• Telecom / Contact Center: NICE CXone, IVR flows, converged communications
• Data: Legacy data routing to support transitional architectures
• DevOps: CI/CD awareness, environment readiness, operational support

Required Skills & Experience

• 8+ years of software engineering experience, including full stack development
• Strong hands-on experience with TypeScript (frontend andbackend development)
• Proven experience leading distributed/offshore engineering teams
• Telecom, converged communications, and/or call center platform experience strongly preferred
• Experience with GraphQL, APIs, and modern cloud-native architectures
• Comfortable operating autonomously in ambiguous, high-pressure environments
• Ability to ramp quickly (expected NICE CXone and GraphQL ramp ~1 week)
• Strong troubleshooting and problem-solving skills
• DevOps mindset: understands deployment, environments, and operational risks

Success Metrics

• Initial pilot delivered by end of April (single branch)
• Full rollout readiness by June, avoiding Avaya renewal risk
• Engineering execution enables — not delays — program milestones
• High-quality, testable, maintainable code with minimal rework
