Uvik Software vs Harnham: overview
Uvik Software
Uvik Software has supplied Python engineers since 2015 and gives Tallinn, Estonia as its headquarters, with sales run from Ipswich in the UK. Its profile on Clutch says all engineers are full-time employees rather than freelancers, average seven to fourteen years of experience and pass a three-stage technical and behavioral assessment. Common work includes data platforms on Databricks or Snowflake, LLM integration and production support. Uvik says it presents profiles within 24 to 48 hours and scales squads of three to eight on 14-day terms. An aggregator reports a 30-day free replacement, which we could not confirm on Uvik's own pages.
Harnham
Harnham has recruited for data and analytics roles since 2006 from London, with offices in the U.S. including New York and San Francisco. It places data engineers, data scientists and ML engineers on contract or permanent terms and runs a graduate training arm, Rockborne. As a recruitment agency, it screens through consultants who specialise in data hiring rather than through practising engineers, and contractors are not managed after placement the way a staffing firm's employees are. That makes it better for permanent hires than for managed augmentation.
