Principal Software Engineer, Client Experience

Job Description

ABCorp is seeking a Principal Software Engineer, Tech Lead to own and evolve our next-generation Client Experience Platform — the cloud-native system through which customers interact with our secure card issuance and manufacturing ecosystem.

This platform is more than a portal. It is the operational and intelligence layer of our business. It combines modern multi-tenant application architecture with deeply integrated APIs, analytics, reporting, and data services to deliver secure, insight-rich workflows at scale.

You will lead the technical direction of this platform end-to-end — shaping frontend experience, backend services, and the data systems that power them — ensuring they operate as one cohesive, high-performance architecture.

This is a hands-on Principal role. You will set engineering standards, guide architecture, mentor engineers, and partner closely with Product and UX to deliver an experience that is modern, elegant, secure, and data-informed by design.

This is an in-person role based in Boston, MA.

• Lead development of a modern React/Angular-based application delivering intuitive, high-quality user experiences.
• Architect scalable APIs and services that power integrations, workflows, and data exchange.
• Design and oversee the data architecture that enables analytics, reporting, and insight-driven customer experiences.
• Ensure system reliability, observability, and security in a regulated financial environment.
• Establish standards for multi-tenant architecture, event-driven systems, and API-first design.
• Mentor engineers across application and data domains, raising technical depth and execution quality.
• Partner closely with Product and UX to ensure design excellence is matched by architectural rigor.
• Leverage modern AI-assisted engineering practices to accelerate development and embed intelligence directly into the platform.

Who You Are

• 10+ years of software engineering experience, including 3+ years in a technical leadership role.
• Proven success building and scaling multi-tenant, cloud-native platforms in production environments.
• Strong full-stack expertise:
• Frontend: React and/or Angular with a passion for high-quality UX

• Data: Analytics pipelines, reporting systems, and scalable data models
• Deep experience with Azure architecture; working knowledge of AWS and GCP.
• Experience designing event-driven systems and API-first platforms.
• Demonstrated ability to unify application engineering and data architecture into a cohesive platform strategy.
• Experience building secure systems in regulated domains (fintech, payments, identity, or similar).
• Strong command of CI/CD, DevSecOps, observability, and infrastructure-as-code.
• Native fluency with AI-accelerated development tools such as GitHub Copilot Enterprise, Azure OpenAI, Claude (including Claude Code), ChatGPT Enterprise, Cursor, and emerging agentic frameworks.
