Characterisation engineers work closest to raw silicon behaviour, running bench measurements across supply voltage, temperature and process corner samples to establish the electrical limits a product must meet before it enters production. Their output becomes the basis for test limits, datasheet specifications and design margin decisions, so accuracy and repeatability matter more than speed.
This role demands fluency with lab instrumentation, careful experiment design, and the statistical judgement to separate real silicon behaviour from measurement noise or setup error. Characterisation engineers frequently work alongside design teams to explain unexpected results, and alongside test engineering to translate lab findings into production-ready limits that do not over- or under-constrain yield.
Because characterisation sits early in a product's life, engineers in this role need patience with ambiguity and strong documentation habits, since their conclusions will be referenced long after the original samples are gone. Nirji Semicon builds this workforce category around candidates who can combine hands-on lab skill with the communication needed to work across design, product and test functions.
