Senior Developer - D365/Power Platform/Azure

Worksite Address: Washington, DC

Interviews: Both Webcam and In Person

Client seeks a hands-on Senior Developer to build, release, and support STAAND on Dynamics 365 and Power Platform. Duties include daily coding, CI/CD and ALM ownership, quality reviews, production support, and direct collaboration with staff to meet needs.

• Personally design and write complex work in the backlog:
  Dataverse plug-ins and custom APIs in C#/.NET, PCF controls, Type Script/JavaScript client extensions, complex Power Fx, Azure Functions and Logic Apps, and integration components.
• Build and maintain integrations across the GCC/commercial boundary, including retry, idempotency, dead-letter handling, and reconciliation logic.
• Optimize platform performance: plug-in execution ordering and depth, query and FetchXML tuning, batching against API and service-protection limits, portal page and cache behavior, and form/view load times.
• Implement portal functionality across six external portals, including web roles, table permissions, and external-user authentication flows.
• Build and maintain automated test coverage — unit tests for plug-ins and custom code, integration tests for interfaces, and UI regression suites.
• Produce prototypes and spikes to de-risk design decisions before entering the sprint backlog.
• Refactor and retire technical debt on a defined cadence.

• Own the Azure Dev Ops YAML build and release pipelines, Power Platform Build Tools tasks, solution export/pack/unpack, environment variables, connection references, and automated deployment across Dev, Test, UAT, Train, and Production.
• Own branching and merge strategy, versioning scheme, and release train cadence; keep all solutions and code under source control with no manual production changes.
• Maintain environment strategy and hygiene with the Architect: refresh cadence, data masking for lower environments, managed environment policies, DLP policy alignment, and capacity monitoring.
• Integrate quality gates into the pipeline: static analysis, Power Platform solution checker, dependency and secret scanning, test execution, and enforced failure thresholds.
• Automate infrastructure provisioning for Azure components (Bicep/ARM or Terraform) so environments are reproducible.
• Plan and execute releases: release notes, deployment runbooks, rollback plans, go/no-go criteria, and post-deployment verification.
• Execute Dynamics 365 biannual release wave and monthly Power Platform update readiness: early-access testing, deprecation remediation, and regression validation against the Architect’s impact plan.
• Continuously reduce release cycle time, deployment failure rate, and manual deployment steps; report DORA-style metrics.

• Serve as primary reviewer and merge authority for pull requests into protected branches.
• Enforce coding standards, security requirements, performance patterns, and test coverage thresholds; reject work with specific, actionable findings.
• Maintain the definition of done, PR checklist, and code review SLA so review does not become a bottleneck.
• Review specifically for security defects: injection, insecure deserialization, hardcoded secrets, unsafe portal permissions, and unsafe handling of PII/PHI.
• Review AI-related changes — prompt modifications, agent tool scoping, grounding source changes — against the Architect’s evaluation framework before merge.
• Mentor CFSA staff and other contract developers through review; treat review as a capability-transfer mechanism.
