Stray electrical currents quietly eat away at buried pipes and rails, and finding and stopping that damage is your work — testing, tracing, and fixing corrosion before it fails. The detective of underground corrosion.
The work mixes field testing with analysis: measuring stray currents, tracing their source, assessing corrosion on underground structures, and recommending fixes. You're out at sites with instruments, then interpreting data. The damage is invisible until something fails, and tracing a stray current takes real detective work.
It's a specialized, somewhat obscure niche, so expertise is rare and built over years. The fieldwork can mean weather and awkward sites, the problems are technical and slow to pin down, and preventing slow corrosion is an uphill sell. Utilities, transit, and pipeline settings shape the work.
It tends to suit people who are analytical, patient, and drawn to invisible problems. If you want fast results or high visibility, the niche may feel quiet. But if you like chasing down damage no one else can see, and the puzzle of it, it's a respected, secure specialty.
