Working in this sector

Use local prototypes, mock tools, public or synthetic data, and licensed research materials for practice; real data access, consequential automation, security testing, and deployment decisions require authorization and appropriate review.

Skills that make the work valuable

  • Language processing pipelines
  • Text dataset evaluation
  • Multilingual error analysis
  • Language model integration

Build proof, not just a list

Build a local classification or extraction experiment with public text and documented language coverage. Compare errors across examples and identify tasks that need additional evaluation.

How to price this work as a freelancer

Agree language coverage, input rights, task definitions, evaluation examples, computing costs, and unsupported-use boundaries before quoting development. Agree the inputs, deliverable, review rounds, and acceptance criteria before quoting. Include preparation, specialist review, equipment or licensing costs, and handover time where relevant. Price ongoing support separately from the initial engagement.

Start with the income you need to replace

Required hourly rate = (target salary + benefits budget + annual business expenses) ÷ (annual billable hours × share of revenue retained after fees).

For illustration, $100/hour × 25 billable hours/week × 48 working weeks = $120,000 revenue. After $20,000 in business expenses, that leaves $100,000 profit before personal taxes. Replacing a $100,000 salary plus $15,000 in benefits under those assumptions takes $112.50/hour, with no percentage fees.

These are editable planning assumptions, not rates surveyed for language technology engineer work. Your personal taxes, location, contract terms, and workload still affect the comparison.
