Senior Full-Stack Developer

We're hiring a Senior Full-Stack Developer with deep Microsoft Power Platform expertise to serve as the build engine for our delivery team. You'll architect and ship applications that combine modern AI capabilities with enterprise-grade UX, workflows, and data integration. You'll own things end-to-end - from Dataverse schema design through PowerApps interfaces, Power Automate workflows, custom connectors, and Power BI reporting.

You'll partner closely with our Senior AI/ML Engineer to integrate LLM-powered features, ML models, and intelligent automation into applications that real users rely on. This is a hands-on building role with significant technical ownership - not a coordinator role.

What You'll Do

• Design and build production applications on the Microsoft Power Platform - canvas apps, model-driven apps, custom connectors, and Power Pages where appropriate.
• Architect Dataverse data models that scale: entities, relationships, security roles, business rules, and audit logging.
• Build Power Automate workflows that orchestrate business logic, approvals, notifications, and integrations with external systems.
• Develop Power BI dashboards and semantic models when reporting is part of the deliverable - DAX, drill-throughs, RLS, the works.
• Integrate AI/ML capabilities into applications by consuming APIs built by our AI engineering team - LLM-powered features, document parsing, classification, and predictive models.
• Design and implement custom connectors and REST integrations with enterprise systems, including authentication, error handling, and observability.
• Own quality end-to-end: testing, performance, accessibility, security patterns, and deployment via ALM pipelines.
• Set technical standards for our Power Platform work - solution architecture, naming conventions, environment strategy, deployment patterns.
• Mentor newer team members and contribute to a strong engineering culture as we grow.

Do you have experience in SQL?, * 4+ years building production applications on the Microsoft Power Platform.

• Strong PowerApps expertise - both canvas and model-driven apps, with real production experience in each.
• Strong Power Automate skills: cloud flows, approvals, error handling, expression syntax, and connector authentication patterns.
• Deep Dataverse expertise: schema design, security model, business rules, plug-ins or low-code alternatives, and performance considerations.
• Power BI fluency: DAX, semantic models, row-level security, and dashboards designed for real users (not just developers).
• Solid SQL, REST APIs, and JSON. Comfortable reading API documentation and integrating against unfamiliar systems.
• Custom connector development experience.
• Experience implementing role-based access control, audit logging, and enterprise security patterns.
• Strong communication skills - you can explain technical tradeoffs to non-technical stakeholders without dumbing them down.

Strongly Preferred

• ALM/DevOps for Power Platform: solution packaging, environment strategy, automated deployment pipelines.
• Power Pages experience.
• SharePoint Online integration patterns.
• Microsoft 365 ecosystem fluency (Teams, Graph API, Azure AD).
• Experience consuming AI/ML APIs (OpenAI, Anthropic, Azure AI Services) inside Power Platform applications.
• Familiarity with Azure services adjacent to Power Platform - Azure Functions, Logic Apps, Service Bus.
• Prior experience in environments with strict security, compliance, or audit requirements.
• Experience working closely with AI/ML engineers in cross-functional delivery teams.
