BI Platform Specialist

At Opensignal, we build customer-facing telecom data products used by operators and industry leaders worldwide. A key part of those products is how data is presented — clearly, interactively, and reliably.

We’re looking for BI engineer to build and improve dashboards using our BI platform, while also supporting the quality and reliability of the platform through hands-on testing.

This role combines dashboard development with validation and testing of BI features.

You’ll take product requirements and turn them into interactive dashboards used directly by customers, while also ensuring that dashboards and platform features behave correctly before release.

You don’t need to know our platform in advance — we’ll teach you. What matters is that you’re comfortable working with data, building dashboards, and carefully validating how things work.

Over time, you’ll build deeper expertise in the platform and become someone others rely on when working with it.

You’ll work across multiple telecom data products, collaborating with product teams, data teams, and engineers to deliver dashboards that are reliable, consistent, and well-tested.

What you will do

• Build interactive, customer-facing dashboards in BI platform

• Translate product requirements into clear and usable visualizations

• Ensure dashboards are stable, accurate, and production-ready

• Review and improve dashboards created by other teams

• Support colleagues in using the platform effectively

• Prepare database views and schemas to support dashboards

• Work closely with engineers to verify BI platform new features

You will work across multiple telecom product groups and collaborate with colleagues in different time zones (including occasional evening calls with North America).

What this role is about

• Building clear, reliable dashboards used by customers

• Making complex data easy to understand and use

• Ensuring dashboards and platform features work correctly before release

• Supporting others in working with data and dashboards

This role requires visibility and communication.
We’re looking for someone proactive, detail-oriented, and comfortable being a go-to person for dashboard and platform-related topics.

What we’re looking for

Must-have:

• 2+ years of experience working with SQL (joins, aggregations, familiarity with CTEs or window functions)

• 2+ year of hands-on experience building dashboards in BI tools (e.g., Power BI, Tableau, Looker, etc.) — from a creator/author perspective, not just as a viewer or end user

• Basic understanding of how data is structured and how queries impact performance

• Clear communication skills in English

• Ability to prioritize work and focus on what matters most

• Practical experience leveraging AI tools to accelerate development and problem-solving

• Attention to detail and ability to validate data and dashboard behavior

Nice to have:

• Experience with BigQuery, Redshift or Postgres

• Familiarity with telecom data

• Basic JavaScript understanding

• Experience with manual testing, QA processes, or validating data-driven products

Growth opportunities

As the platform continues to grow, this role can expand into broader platform-related responsibilities, including:

• Improving dashboard standards and template structure

• Supporting governance and quality processes

• Taking more ownership of complex dashboards across products

• Analyzing platform usage and user behavior (Google Analytics)

• Working with logs and data to improve stability and reliability

• Expanding involvement in testing, validation, and release processes

• Expanding into wider data or platform-oriented roles within the company

The BI platform sits at the center of multiple telecom products, creating opportunities to deepen your technical skills and increase your impact over time.
