Are you a technologist who enjoys turning ambiguity into working software at scale, and who now wants to shape not just what gets built, but how an entire engineering organization builds it? Are you energized by mentoring the next generation of technical leaders, setting architectural direction across teams, and being the person others turn to when a problem has no obvious answer? Are you ready to define how the future of Workflow capabilities drives business value at Deloitte Global Employer Services (GES)?
If you want your work to matter at global scale, in a stack that's actively modernizing (including AI-led engineering), and on a team that values judgment as much as code - we'd like to talk.
Work you'll do As a Principal Software Engineer on our GlobalAdvantage (GA) platform, you'll set the technical direction for the workflow and integration capabilities at the center of that transformation. This is a role for an engineer who operates as a force multiplier - someone who resolves the organization's hardest technical ambiguity, makes architectural calls with broad and lasting impact, and raises the engineering bar not just for a team, but across the platform.
You'll own the technical strategy for workflow and integration end to end - from architecture through long-term platform health - and act as a primary technical authority others rely on. Day to day, you will:
- Define and evolve product engineering for workflow and task management capabilities that power GES business processes - using Pega, .NET, C# and other technologies - and set standards other engineers build against.
- Architect REST APIs, microservices, and integration services that scale across internal and client-facing platforms, with an eye toward long-term maintainability and reuse.
- Own outcomes across multiple modules and workstreams - including technical strategy, effort estimation, risk identification, and production reliability - and are accountable for quality and architectural integrity across the codebase.
- Drive technical design decisions, lead code and architecture reviews, and set engineering standards for the platform, exercising judgment on trade-offs that other engineers and leaders rely on.
- Elevate the organization by mentoring senior and staff-level engineers, developing technical leadership in others, and building the practices that let the team scale - while staying open to sharpening your own thinking through architects, quality engineers, and peers.
- Partner directly with product managers, architects, technical program managers, engineering managers, quality engineers, and business stakeholders to translate business strategy into technical roadmaps.
- Guide continuous improvement of the platform - performance, application stability, supportability, and delivery practices - at an organizational level, not just within a single feature.
A successful candidate would possess these skills:
- Ability to work independently and collaborate as part of a team
- Effective written and verbal communication skills
- Meticulous attention to detail and quality of work product
- Ability to build and sustain professional relationships
- Ability to lead projects or workstreams
- Ability to manage and prioritize multiple tasks in a fast-paced and dynamic environment
- Strong interpersonal skills and professional demeanor
- Ability to meet deadlines
- Ability to mentor and provide clear guidance to others
