Er. Jessica Yip · Professional Engineer (Mechanical) · Singapore Some heroes wear hard hats.
Mother of two sons. One of 561 practising mechanical PEs in Singapore. She retired, came back, and gave away advice that cost her the job because it was the right advice. CVC Engineers made this site to say thank you.

She retired. Then she came back.
Er. Jessica Yip is a mother of two sons. Like many engineers who become parents, she stepped back from practice. Nobody would have blamed her for staying there.
She came back because Singapore's mechanical sector is short of Professional Engineers, and she knew she could help. Her name entered the Professional Engineers Board's register on 26 January 2023, in the largest single-year group of mechanical PEs still practising today.
Having two sons at home didn't stop her. If anything, they are part of the reason. Every building she signs off is one their generation will live and work in.

Her story is personal. The public data shows why it matters to everyone else. Every figure below comes from a public Singapore source.
“If it helps,
it helps.”
We met Er. Jessica Yip the way most people in this industry meet a PE: we needed one. One of our clients had a compliance requirement on the mechanical side, and by every normal measure the next step was to engage her.
She read the drawings and listened. Then she showed us a route, within the prevailing regulations, that met the requirement without the client needing to engage her at all.
She didn't charge for that advice. We later learned we weren't the only ones; she has done the same for other clients. When we thanked her, the explanation was four words long.
That is talent: knowing the regulations well enough to find the shortest compliant route, and being decent enough to recommend it when it costs you the job. Five questions to ask before you engage a PE →
Women hold 340 of the 4,231 Professional Engineer registrations in Singapore. They are about 22% of engineering students but only 8% of PEs. She is in that 8%, and she got there while raising two boys.
What she engineers.
These are the systems you never notice until they fail: the air you breathe indoors, the water in the pipes, the sprinklers over your head. Deneed designs and submits them; Er. Yip endorses the mechanical work.
