What will you do

Own the customer-facing proof: a certified drill-down billing view where each of 11 Operating Administrations can see its actual bill, the outputs billed, the rates charged, the calculations behind them, and the inputs those calculations used — five layers, one click at a time. The governing discipline: the reporting layer exposes controlled data; it never becomes a second source of truth. The client environment is Google-based — Google Workspace (Sheets, Drive, Chat, AppSheet, Apps Script) and Google Cloud analytics (BigQuery, Dataform, Looker), alongside Delphi, ServiceNow, and PRISM. Candidates with Microsoft-stack depth (Power BI, Power Automate, Power Query, SQL Server) and the aptitude to transfer are strong fits; direct Google-stack experience is a significant plus.

Responsibilities:

· Design and build the OA drill-down billing views in Looker (LookML semantic models) and Looker Studio: bill → outputs → rates → calculations → inputs, with the reconciliation to Delphi one click beneath.

· Build against certified datasets only; implement view-equals-bill reconciliation checks so publication is blocked until the customer view ties to the issued bill and the bill ties to Delphi.

· Implement OA data segregation in the semantic layer (Looker access filters and user attributes) aligned to the data-layer row-level policies; test roles before every release.

· Enforce display discipline: estimates, accruals, proxies, true-ups, and pending corrections labeled and visually distinct from posted actuals; prior-period corrections linked, never blended; refresh date and period-covered shown on every page.

· Deliver Section 508-conformant reports and views as a release-readiness requirement, not an afterthought.

· Build the operational metrics views: dispute and exception aging, unexplained adjustments, cycle time, and bill-line traceability against DOT-set baselines.

· Document the semantic model and view logic so Government personnel can maintain and extend the reporting layer.

Requirements:

· Security Clearance: Public Trust or the ability to obtain one.

· Candidates whose experience is limited to advisory, strategic, or conceptual consulting will not meet this program's bar. The client explicitly requires demonstrated, hands-on implementation experience — deployed cost models, executed billing cycles, delivered automations, and operational financial products.

· Bachelor’s degree in Computer Science, Information Systems, Data Analytics, or a related field, or equivalent additional experience.

· 4+ years of BI development with semantic-layer modeling (LookML, Power BI datasets/DAX, or equivalent) and strong SQL.

· Demonstrated delivery of stakeholder-facing financial dashboards with drill-through from summary to transaction-level support.

· Experience implementing report-layer security for multi-tenant or multi-customer audiences.

· Design judgment for executive and analyst audiences — clarity at the summary, completeness at the detail, honesty in the labeling.

· Looker and LookML; Looker Studio; BigQuery as the backing store; Connected Sheets for analyst access.

· Power BI or Tableau depth with clear transfer aptitude — semantic modeling and row-level security patterns carry directly.

· Federal financial reporting context (WCF billing, audit-ready lineage); Section 508 / accessibility testing experience.

· Family Health Care (54% cost covered for the entire family)

· Family Dental (54% cost covered for the entire family)

· Family Vision (54% cost covered for the entire family)

· Flexible Spending Account

· Overutilization bonuses for Time and Materials (T&M) contracts

· Lifetime Event Bonuses (e.g., child, marriage)

· Profit-sharing arrangement for any work brought into the company

· Unlimited Leave with Approval

· 401k 100% employer match on first 4% invested

· $1,000 training budget
