Your career at SelectFromData
The Consulting Path
Robin Vale · Principal · SelectFromData
Welcome to the firm. You'll work across five clients — a manufacturer, a bank, an energy utility, a care network, and a global reinsurer. Start with the junior engagements; deliver well and you'll earn the rank to take on the harder work.
Principal requires at least 2 Senior engagements.
Your engagements
Pick a client and deliver. This is the career path — each engagement is a hands-on SQL exercise. The level badge tells you the SQL it needs.
New to SQL? Engagements assume you can already write queries. You can dive straight inand lean on each engagement's prep panel — or build the basics first.

Manufacturing & Supply Chain
A heavy-equipment manufacturer. Carriers, inventory, and a sales review that has to be right before the quarterly board.
▸ Inside Northforge Industrial
Northforge builds compressors and mining rigs across nine countries. Its supply chain runs on spreadsheets that became systems that became a pipeline nobody fully understands anymore.
The people. Marco runs operations and wants answers, not caveats; Ina is the analyst who reads the data closely; Petra negotiates the carrier contracts your findings decide; Sef, the plant director, is who it escalates to.
Your remit. The factory floor is unforgiving — a wrong number means a stockout or an overpaid carrier. Your job is to make the data as reliable as the machines.

Keystone Bank
Banking & Investments
A retail and investment bank. Monday standups, finance reconciliations, and a marketing team that wants attribution.
▸ Inside Keystone Bank
Keystone is a 150-year-old Amsterdam bank that bolted a modern investment arm onto a mainframe core. The data warehouse is where those two worlds collide — and where the numbers quietly go wrong.
The people. Saskia owns the client relationships and the deadlines; Tom owns the data and the skepticism; Yara is the analyst who actually finds the bug. Olef, the CFO, only appears when real money is on the line.
Your remit. Every engagement here is the same fight in a new costume: the business trusts the dashboard, the dashboard trusts the warehouse, and the warehouse can't be trusted. You are the one closing that gap.

Helios Energy
Energy & Utilities
A consumer energy utility moving into home plans and EV charging. Growth, workforce, and a leaky signup funnel.
▸ Inside Helios Energy
Helios is a utility reinventing itself as a consumer tech company — home energy plans, EV charging, an app with a million signups. Growth is fast, the data model is faster, and nothing is quite consistent yet.
The people. Alex chases commercial growth; Jade builds the data platform under his feet; Rens wants every funnel number yesterday; Paula keeps the workforce side honest when the others are distracted by the curve.
Your remit. Hypergrowth hides its sins in averages. You are the one pulling the real signal out of a company moving too fast to check itself.

Lumen Care
Health & Patient CRM
A care network with clinics and a pharmacy arm. Clinician workload and patient retention, where the data is sensitive.
▸ Inside Lumen Care
Lumen runs a network of clinics and a pharmacy arm, where the data is sensitive and the stakes are human. Patient records, clinician workload, retention — every query touches someone's care.
The people. Dr. Patel guards clinical integrity and pushes back hard; Rik runs the data platform; Ana bridges the two as clinical analyst; Tess drives patient retention from the commercial side.
Your remit. Here a data error isn't a wrong dashboard — it's a doctor overloaded or a patient quietly lost. Precision and privacy are not optional.

Global Reinsurance & Specialty Risk
