Senior Principal, Software Engineering Providence , RI

MojoTech is an innovative technology consulting firm that integrates strategy, design, data, and software engineering to create results-driven, AI-enabled digital products and experiences.

We partner with our clients to discover, define, design, and build tomorrow’s innovations, empowering organizations to unlock future market potential, maximize returns on innovation, and drive transformational change.

Role Overview

We are looking for a Senior Principal Software Architect with deep expertise in Microsoft Azure, .NET, and AI-accelerated software development to lead client engagements across architecture, delivery, and growth.

This role combines hands-on technical leadership with client engagement and business development. You will work directly with client stakeholders to modernize applications, shape cloud solutions, guide teams through delivery, and grow accounts through trusted relationships and strong outcomes.

You will also help teams adopt AI-assisted and agentic development practices responsibly. This includes using AI to accelerate software design, implementation, code review, debugging, documentation, and delivery while ensuring that people remain accountable for architectural decisions, quality, security, and production readiness.

You will be expected to stay close to the work. This is a hands-on leadership role in which you will set technical direction, evaluate architecture and code, unblock teams, and step in when needed to move delivery forward.

• Establish clear standards for reviewing, validating, testing, and securing AI-generated code and technical outputs
• Design workflows in which humans remain accountable for architectural decisions, implementation quality, security, compliance, and production outcomes
• Use rapid prototyping to validate ideas and technical approaches, followed by structured production hardening across architecture, code quality, security, testing, performance, observability, and maintainability
• Help teams determine where AI-assisted or agentic workflows provide meaningful value and where traditional engineering approaches are more appropriate
• Monitor the effectiveness of AI-enabled engineering practices and continuously improve the team’s tools, workflows, and quality controls
• Coach clients and delivery teams on the responsible adoption of AI-accelerated software engineering practices

Client Engagement

• Work directly with client stakeholders to understand business and technical challenges, define solutions, and align on measurable outcomes
• Lead discovery engagements, application and cloud assessments, modernization planning, and early-stage solution design
• Assess existing .NET applications and Azure environments to identify technical debt, security risks, operational gaps, and modernization opportunities
• Evaluate client software delivery practices and identify opportunities to introduce AI-assisted and agentic development workflows
• Facilitate technical workshops and architecture discussions with engineering teams, business leaders, and executive stakeholders
• Translate business requirements into clear, executable technical strategies, roadmaps, and delivery plans
• Communicate complex Azure, .NET, and AI-enabled engineering concepts to technical and nontechnical audiences
• Build strong client relationships that position MojoTech as a trusted technology and delivery partner

Sales and Growth

• Partner with account and sales leaders to shape and win Azure, .NET, application modernization, and AI-accelerated engineering engagements
• Contribute to proposals, estimates, staffing plans, technical approaches, and client presentations
• Support technical discovery and solutioning during the sales process
• Identify follow-on opportunities within existing client engagements
• Clearly articulate the business and technical value of proposed solutions
• Help develop reusable Azure, .NET, cloud modernization, and AI-enabled engineering offerings, reference architectures, accelerators, and delivery approaches

Program and Delivery Leadership

• Lead technical delivery across one or more engagements, ensuring work remains aligned with agreed goals, timelines, budgets, and quality expectations
• Establish lightweight governance, planning, architecture decision-making, and communication practices that keep teams moving
• Coordinate across engineering, product, design, data, cloud infrastructure, and security disciplines
• Structure work so teams can safely use parallelized and agentic development approaches while maintaining appropriate review and integration controls
• Identify architectural, technical, and delivery risks early and work with teams and client stakeholders to address them
• Ensure architecture decisions are translated into working software and consistently implemented across delivery teams
• Maintain a strong focus on production readiness, measurable outcomes, and sustainable client ownership
• Ensure rapid prototypes move through a defined production-hardening process before release

Team and Practice Leadership

• Mentor engineers and architects and help develop technical leadership across project teams
