Holland Mountain

ATLAS BI Developer

Build insights. Drive impact. Thrive in pace.

Workplace: Hybrid (3 days in the office) Location: London Bridge

Are you a BI Developer who loves turning data into meaningful insight and thrives in environments where no two days are the same?

At Holland Mountain - Atlas, we’re looking for developers who go beyond technical delivery. This is a role for people who enjoy working at speed, partnering with clients, and navigating complexity with confidence.

What makes this role different?

This isn’t a traditional, slow-moving BI position. You’ll be working in a dynamic, client-facing environment where:

• Priorities shift
• Requirements evolve
• Multiple workstreams run in parallel

If you enjoy variety, ownership, and solving problems in real time you’ll fit right in.

What you’ll bring

We’re looking for BI Developers who combine strong technical skills with adaptability and ownership. You’ll:

• Work across multiple projects and stakeholders simultaneously
• Translate unclear or evolving requirements into effective solutions
• Balance delivery across competing priorities — without compromising quality
• Communicate confidently with both technical and non-technical audiences
• Take real ownership of outcomes, not just tasks

The kind of experience that stands out

You’ll likely have experience in:

• Consulting or client delivery environments
• Fast-paced teams with shifting priorities
• Situations where you’ve had to figure things out without all the answers upfront

We value people who can demonstrate how they’ve:

• Managed conflicting deadlines
• Delivered in ambiguous or rapidly changing environments
• Worked directly with clients or senior stakeholders

Core Technical Expertise

• Strong SQL Server development skills, including writing and optimising T-SQL queries and stored procedures.
• Experience developing and maintaining SSAS multidimensional and Tabular models, including DAX calculations.
• Working knowledge of BI and data warehousing methodologies, with the ability to implement solutions in line with agreed approaches and standards.
• Familiarity with Azure data services and modern data platform components.
• Experience applying data validation and testing techniques to ensure data accuracy, reliability, and quality.
• Ability to work within established architectural patterns, data models, and development standards.
• Programming or scripting experience is desirable.
• Experience working within Data Vault and Kimball modelling approaches.

A quick reality check

This role isn’t suited to those who have only worked in highly structured, single-project environments. Success here requires flexibility, resilience, and a proactive mindset.

And while many candidates say they enjoy fast-paced work, we’re looking for those who can prove it with real examples.
