Hire senior Power BI developers for reports people trust
Senior Power BI developers who design semantic models, write DAX that performs and run governed workspaces, working inside your team within an hour of US time zones.
By the Ryz Labs team · Updated October 2026
Hiring Power BI developers through Ryz gets you senior Latin American developers who build semantic models, reports and governance that hold up as usage grows. They are top 1% of the candidates we interview, they embed in your team and tenant, and they work within an hour of US time zones.
What our Power BI developers work on
Our Power BI developers handle the full path from source data to a report a regional manager opens every morning. They work in Power BI Desktop, the Power BI service and Microsoft Fabric, with Power Query, DAX, Tabular Editor, DAX Studio and deployment pipelines, on top of SQL Server, Azure SQL, Synapse, Snowflake or Databricks. Typical projects:
- Star-schema semantic models that replace dozens of one-off datasets with a few certified, shared ones.
- Executive and operational reports with drill-through, bookmarks, field parameters and mobile layouts.
- Performance work on slow reports: DAX rewrites, model slimming, aggregations and moving to incremental refresh.
- Row-level and object-level security for regions, business units or external customers.
- Migrations from Excel, SSRS, Tableau or Qlik into Power BI, including reconciliation of the numbers.
- Power BI Embedded for customer-facing analytics inside a SaaS product.
- Workspace, capacity and lifecycle setup with Git integration, deployment pipelines and Fabric lakehouses.
Skills we vet for
- DAX at depth. Filter context and context transition, CALCULATE modifiers, iterators, time intelligence and variables that keep measures readable.
- Data modeling. Fact and dimension design, relationship direction, role-playing dates, and avoiding bidirectional filters and many-to-many traps.
- Power Query (M). Query folding, parameters, incremental refresh policies and keeping transformation logic upstream when it belongs there.
- Storage modes. Import, DirectQuery, Direct Lake and composite models, and the trade-offs in freshness, cost and speed.
- Performance tooling. Performance Analyzer, DAX Studio server timings, VertiPaq Analyzer and Tabular Editor's Best Practice Analyzer.
- Security and governance. RLS and OLS, sensitivity labels, workspace roles, endorsement and certified datasets.
- Lifecycle management. PBIP files and Git, deployment pipelines, XMLA endpoint deployments and change control across dev, test and production.
- SQL. Enough to build clean views upstream and push heavy work to the warehouse rather than into the model.
How we vet Power BI developers
Our recruiters look for developers who have owned models with many users, not just built visuals. Our in-house ARC system ranks the pipeline, and candidates complete structured NTRVSTA AI interviews focused on DAX reasoning, modeling decisions and performance troubleshooting. Recruiters review every candidate before and after, then send a curated shortlist. AI scores are advisory, and humans make the decisions.
Sample interview topics
- A measure returns the right total but wrong values per row in a matrix. Explain filter context versus row context and how you would fix it.
- A report takes 20 seconds to render a single page. Walk through how you would use DAX Studio and Performance Analyzer to find the cause.
- Design RLS for a sales model where managers see their region and the regions of everyone who reports to them.
- When would you choose DirectQuery or Direct Lake over Import, and what breaks when you switch?
- How do you set up source control and promotion for a shared semantic model that ten report authors depend on?
Ways to hire Power BI developers
| Option | Best for | Trade-offs |
|---|
| Freelance marketplace | One report or a quick visual refresh | Often produces another standalone dataset rather than a shared model your team can maintain. |
| Staffing or recruiting agency | Roles with a clear Microsoft BI checklist | Certifications and keywords do not show DAX reasoning or modeling judgment. |
| In-house recruiting | A permanent BI center of excellence | Slow to staff, and hard to assess DAX skill without a senior BI lead on the panel. |
| Ryz Labs staff augmentation | Adding senior Power BI developers to an existing data or finance team | You own priorities and governance. Best when there is a warehouse or lakehouse to build on. |
| Ryz Labs dedicated team | A BI migration or rebuild across models, pipelines and reports | A dedicated team with BI and data engineers working together. Scoped as a team with a plan up front. |
If you want a self-serve marketplace for a few hours of report formatting, or published pricing before any conversation, Ryz is not the right fit.
Why hire Power BI developers from Latin America
Reporting work is full of quick feedback loops. A finance lead spots a number that looks off, a sales director wants a new slicer before the quarterly review. Power BI developers who share your working hours can sit in that review, fix the measure and republish the same afternoon.
Microsoft's data stack is widely used across Latin American enterprises and global companies with regional operations, so senior developers there have often run large tenants, multi-language reports and complex security models. They document their models in English and work directly with business owners.

FAQ
Do your Power BI developers work with Microsoft Fabric?
Yes. Many have worked with Fabric lakehouses, warehouses and Direct Lake models, alongside classic Power BI Premium or Pro setups. We match the developer to the setup you run today and the one you are moving toward.
Can they fix our slow reports without rebuilding everything?
Usually. Most slow reports come from a handful of causes: model design, heavy DAX or missing aggregations. A senior developer can profile the model and fix the biggest issues first.
How is pricing set?
Custom quote, scoped per team. Before you sign, you receive a scoped plan, a price and the names of the people who would do the work.
Who do we contract with, and which hours do they cover?
You sign one contract with Ryz. Our developers work with us as independent contractors, and we handle paying them. They keep hours within an hour of US time zones.
Can a Power BI developer also build the data pipelines?
Some can, especially with Power Query, Dataflows or Fabric pipelines. For larger warehouse work, we usually pair them with a data engineer.
