Job description

At Broadridge, we've built a culture where the highest goal is to empower others to accomplish more. If you're passionate about developing your career, while helping others along the way, come join the Broadridge team.

We are looking for a Principal Engineer to provide technical leadership and practical ownership for a new SaaS platform, while helping shape selected AI-enabled initiatives across the software delivery lifecycle.

This is a senior, hands-on technical leadership role. You will set the platform's technical direction, architecture, engineering standards, and technical roadmap, ensuring it evolves into a scalable, secure, resilient, and maintainable product.

The platform uses C# and .NET, PostgreSQL, AWS, and frontend applications built with Blazor and MudBlazor. It includes APIs, event-driven integration, BFFs, and cloud services including Lambda, ECS and EC2.

You will report directly to the Director of Software Engineering and work closely with the Software Architect, Software Development Manager and Lead Engineers. The Software Architect provides wider architectural alignment and challenge; you will own the practical technical direction and delivery reality of the SaaS platform. This is not a people-management role. You will lead through technical judgement, clarity, influence, mentoring, and targeted hands-on contribution.

Key Responsibilities

• Own and evolve the technical strategy, target architecture and engineering roadmap for the SaaS platform.
• Provide clear technical direction across architecture, engineering standards, platform design, technical risk and long-term maintainability.
• Define appropriate service boundaries, APIs, event flows, integration patterns, data ownership and frontend integration approaches.
• Lead significant technical decisions and design reviews, balancing delivery speed, security, resilience, scalability, operational needs and long-term value.
• Work with the Software Architect to align major platform decisions with wider architectural principles and organisational direction.
• Partner with the Software Development Manager and Lead Engineers to turn technical direction into practical delivery plans and sustainable execution.
• Make high-leverage hands-on contributions through prototypes, reference implementations, critical-path work and support for complex technical problems.
• Improve platform reliability, security, observability, performance, cloud maturity and operational readiness in AWS.
• Strengthen engineering effectiveness through pragmatic standards, CI/CD, build and deployment practices, developer experience, testing and quality controls.
• Identify and address material technical risks, dependencies, bottlenecks and architectural debt early.
• Shape the effective and responsible use of AI-assisted development, selected AI agents and agent-enabled SDLC workflows.
• Mentor engineers and Lead Engineers, raising technical capability, architectural judgement and engineering consistency.

Requirements

Essential Qualifications

• Significant commercial software-engineering experience, including deep hands on experience with C# and .NET.
• Experience owning or materially shaping the technical direction and architecture of complex production software platforms.
• Strong experience designing APIs, distributed systems, event-driven architectures and service-based applications.
• Sound judgement on service boundaries, asynchronous integration, event flows, data ownership and distributed-system trade-offs.
• Strong experience with relational databases, ideally PostgreSQL.
• Experience defining technical roadmaps, engineering standards, target architectures or technology strategy across multiple workstreams or teams.
• Strong understanding of software design, testing, quality, security, observability, reliability and maintainable system design.
• Experience with CI/CD, deployment pipelines, build automation and modern software-delivery practices; Jenkins experience is strongly preferred.
• Experience making and communicating consequential technical trade-offs to both technical and non-technical stakeholders.
• Experience improving engineering practices, developer experience and delivery effectiveness.
• Practical experience using AI-assisted development tools and evaluating where AI-enabled engineering workflows create genuine value.
• A track record of mentoring engineers and leading through influence rather than formal line management.

Desirable Qualifications

• Experience with AWS, particularly Lambda, ECS, EC2 and cloud-native architectural patterns.
• Experience with Docker, infrastructure as code and environment automation.
• Experience with messaging, event streaming or other event-driven technologies.
• Experience with BFF patterns, Blazor and MudBlazor.
• Experience establishing architecture governance, decision records, technical standards or reference architectures.
• Experience designing, operating or governing AI agents or LLM-enabled engineering workflows.
• Experience in a growing product or platform-engine
