People who take responsibility for what no one sees
A cleanroom's quality starts with its air, and that air travels through ducts above the ceiling and pipes inside the walls. Once a project is handed over, no one sees those places again, yet that is exactly where SAMYOUNG ENG's work is finished.

Core ValuesIntegrity, responsibility, quality and togetherness
Integrity, responsibility, quality and togetherness
To our three core values we add one more: enjoying the work together. This is the kind of person SAMYOUNG ENG wants to work with.

- 01 Integrity
Integrity
We follow the standard even when no one is watching
Our promises to clients are kept in drawings and records. We want to work with people who raise what went wrong as readily as what went right.
- Build and record to standard even the parts the finishes will hide.
- Share a mistake the moment you find it, instead of covering it up.
- Say so when you don't know, then find out.
- 02 Responsibility
Responsibility
We think beyond the end of our own task
Design, construction, validation and maintenance form one continuous process. Every stage has to leave work the next stage can pick up.
- Think through how your drawings will actually be built on site.
- Hand your work over in a state the next person can use straight away.
- Put safety ahead of the schedule.
- 03 Quality
Quality
We grow into GMP and HVAC experts by learning
Quality rises with knowledge. We value the habit of checking once more and learning more than yesterday over the experience you have today.
- Ask why a regulation or standard exists, not only what it says.
- Keep building expertise through certifications and training.
- Learn AI and new tools, and use them to improve how we work.
- 04 Together
Togetherness
We grow together and enjoy the work
A cleanroom is only complete when building, HVAC, piping and controls fit together. We look for people who solve problems alongside their colleagues, through open communication and respect.
- Speak your mind clearly, and hear your colleagues out.
- Take the lead on work that falls between departments.
- Be someone colleagues can lean on, even on a tough site.

What we promise in return
Room to learn
We cover training and book costs, and pay certification bonuses and certification allowances.
Smarter ways to work
We are building our own AI services for office and site work. The goal is less repetitive work and more time for engineering.
Time to rest
No one asks why you are taking annual leave. We aim to finish on time, and we have a lounge and a nap room.
Respect
We keep a close, family-like atmosphere where people look out for each other. Team dinners are optional, and no one is pressured to drink.
A place to stay
Many of our colleagues have been with us for years. We hire on permanent contracts, pay full salary during probation, offer dormitory support and reward long service.
Generous holidays
For the major holidays we usually give two or more gifts plus a holiday bonus.
Time to enjoy together
Staff can use a guesthouse on Daebudo island and a Daemyung Resort membership, and we have an indoor golf simulator at the office.
Shared success
When we hit our targets, we go on an overseas workshop together. We have been about three times so far.
