START WITH FDE

Researchers work as FDEs

FDE stands for Forward Deployed Engineer. Instead of waiting for a ticket inside a development team, an FDE works close to where the work actually happens, finds the problem directly, builds the tool, and puts it to use right away. AI has cut the time it takes to build, so more of our time goes into deciding what to build and checking that the work on the ground actually got easier.

How we work — automation comes last

The most common mistake is automating work that should not exist. So researchers always work in the same order.

  1. FIND

    Find inefficiency

    Find where the people doing the work struggle most: repetitive manual tasks and information copied down more than once.

    1. 01 Question every requirement Ask why the work is needed and who set the standard.
    2. 02 Delete any step you can Remove before you reduce.
  2. BUILD

    Build the tool

    Build apps, web tools, and automation quickly together with the latest AI models.

    1. 03 Simplify what remains
    2. 04 Speed it up
    3. 05 Automate last
  3. DEPLOY

    Put it to work

    We use every tool ourselves first (dogfooding), then keep fixing it until the friction is gone for the actual team.

    After one lap, back to 01. The loop never stops.

What comes in, what goes out

AX only works when DX is done well first. That is why a researcher’s output is not a single AI model—it is a tool colleagues use every day, and the data that builds up every time they use it.

01INPUT

Repetitive work + handwritten and Excel records

How each department works and records information, scattered across teams

02WORK

DX built for AX

Go beyond digitizing: store data in a connectable structure that AI can learn from

03OUTPUT

In-house tools + growing data

More efficient work and the raw material for our own AI

A DAY IN THE ROLE

The day moves between departments and the screen

A researcher does not stare at a monitor all day. You go to where the work happens, watch, build, and teach.

01START

Check requests and usage

Review complaints raised by departments and how the deployed tools are being used.

02FIELD

Observe alongside departments

Watch the actual work next to design, quality, and administration staff and ask questions.

03BUILD

Develop with AI

Build and fix app and web features together with the latest models.

04TEACH

In-house AI training

Run AI training for colleagues who are interested, and help them build their own tools through AI-assisted coding.

05EXPLORE

Experiment with new models

Try new models and concepts as soon as they launch and share them with the team.

AI ENVIRONMENT

The most talked-about AI, with effectively no limit

This role’s biggest advantage is its tools. BAEKSAN ENG works with the best AI models available at any given time. There is effectively no limit on usage for work, and new models are adopted quickly as soon as they launch.

09Frontier model
The newest, highest-performing model released by each AI company

WHO FITS

What matters more than your major

Above all, we look for the drive to see a problem through and the ability to communicate and work with non-developer colleagues. Your major matters little. How well you use AI and how quickly you pick up new things matter more.

  1. 01You break down and define problems that have no set answer, and solve them all the way through.
  2. 02You listen to non-developer colleagues all the way through, and can explain technical ideas in plain language.
  3. 03You use AI every day and look for better ways to use it.
  4. 04You do not skip past unfamiliar terms and concepts—you try to understand them.
  5. 05You pick up new tools quickly and put them to work right away.
  6. 06You are curious enough about what AI can do that you test it yourself.
  7. 07You wonder, “Why does the field work this way?”

JOIN THE TEAM

If you join us

Here is what you will experience and the tools you will work with once you join.

What you will experience and grow into

  1. 01Owning the whole cycle yourself, from finding a problem to deploying and improving the tool
  2. 02Building our own AI from data that exists nowhere on the internet, in the rare domain of semiconductor piping
  3. 03Seeing firsthand how the tools you build change your colleagues’ work right away
  4. 04Growing through new ways of working with the best AI models available at the time

The technology you will use

You choose the stack

There is no fixed stack. Developers choose the language and framework that best fit the problem, and Rust is welcome too. There is one principle to follow: design backend APIs so they can be connected to each other later—because connecting scattered data is how we build our own AI.

HOW TO APPLY

Before you apply

Here is what we look for, what we will ask about in the interview, and how the hiring process works.

Preferred

  • Six months or more on Claude Max or ChatGPT Pro

    We look for at least six months of experience on a Claude Max (Claude Code) or ChatGPT Pro (Codex) plan. It helps us see how much you have actually been using AI. We will only ask to see your usage history after you pass the document screening.

  • A GitHub history from before ChatGPT’s release (November 30, 2022)

    Even now that AI writes much of the code, the fundamentals you build by writing code yourself make a real difference when debugging and designing prompts. For example, instead of only describing what you want in words, you can write a short code example yourself and give it to the AI, and get far more accurate results.

  • Machine learning or deep learning study

    Self-study or related coursework both count. Understanding the basics of how LLMs work makes you far better at using AI.

  • Linear algebra, proof-based math, or logic

    This includes linear algebra (matrices), proof-based mathematics such as analysis or discrete math, and logic. LLMs run on matrix operations, and the habit of building an argument one step at a time into a proof is what lets you work through complex problems.

  • Deep commitment to one field, or starting something yourself

    Experience of committing to one field for a long time and reaching a high level—as an athlete, a pro gamer, or a Go player, for example—is a plus. You do not need tournament results or rankings. Years of repetition that others find boring, analyzing every loss and fixing it next time, is enough. We look at starting something nobody asked you to—a startup, a side project, running a club or community—and seeing it through the same way. What we are looking for is the ability to think deeply, the persistence to finish, and a founder’s drive to find problems and act without being told. A researcher’s work is also about defining problems with no set answer and staying with them for a long time, so this experience carries straight over.

What we will ask about in the interview

  • Programs you enrolled in after November 24, 2025 (Claude Opus 4.5 release)

    If you enrolled in a new university, graduate, or academy program, we will ask why you made that choice. At a time when AI and open materials let you study deeply on your own, tell us why you chose an outside program and what you actually gained from it.

  • A time you lost track of time in deep focus

    In Flow, psychologist Mihaly Csikszentmihalyi describes the state of becoming so absorbed that you lose track of time, which happens when your skill and the challenge are well matched. Whether it was study, games, or sports, we will ask when you experienced it and what made it happen. The ability to stay with a hard problem for a long time usually comes from there.

Hiring process

  1. 01 Application

    Submit your résumé through our job posting on Saramin.

  2. 02 AssignmentMay be skipped

    A short assignment where you build a real AI tool with AI-assisted coding. You do it from home and submit the result.

  3. 03 In-person training & interview

    We meet in person. After a short training session (one-on-one or in a group), you use what you learned to build a result with AI-assisted coding while we interview you. It is similar to a technical interview, but there is no LeetCode-style algorithm coding test. It shows whether our ways of communicating fit, how quickly you pick up new things, and how you think about your past projects and your work.

  4. 04 Reference checkMay be skipped

    For experienced candidates, we ask people you have worked with about collaborating with you. For new graduates, we ask someone who can speak to your reputation, such as a teacher, an acquaintance, or a family member.

  5. 05 Offer

    We discuss compensation based on the role and your experience.

  6. 06 Join

    You join the Technology Development Support Team.

  • Step 02 (assignment) and step 04 (reference check) may be skipped depending on the candidate.
  • You keep the rights to anything you create for the assignment or the in-person training and interview; we use it only to evaluate your application.

FROM THE TEAM

We heard directly from a researcher

Did you always like computers?

I have liked computers since I was a kid, and I used to buy parts and assemble them myself. That interest carried into college, where I double-majored in computer science and mathematics.

So your major must have helped the most in this job.

Honestly, I think which school or department you graduated from matters much less than it used to. What matters now is what problems you have solved, what questions you asked and how you got to the answer, and what you have actually built. Inside the company, too, people are judged on skill and results, not on their education or credentials. And the starting point for all of that is curiosity about AI.

You probably did not know much about piping. How do you learn?

I say plainly when I do not know something, and ask the person who knows that field best. On site there are people who have worked with piping and processes for a long time. Listening to them all the way through and learning from them is half my job. I do not try to know everything myself. I leave specialist knowledge to the specialists, and focus on making that knowledge work properly inside our tools.

As a researcher, do you build AI models all day?

Surprisingly, I do not spend much time building AI models themselves. Most of my time goes into building the apps and websites that collect the data an AI will need. Semiconductor piping jobsite data does not exist anywhere on the internet, so gathering it ourselves is the real starting point of AI development.

What does building apps and websites have to do with AI?

AX only works when DX is done well first. Honestly, much of the company’s work is still not organized digitally, so we are moving the whole company’s work processes onto digital tools. But it is a little different from typical DX. We collect data with AI in mind from the start, and connect the data we need to build our own AI.

What kind of app do you build to collect data?

A representative example is the 3D Pipe Editor. It moved bend-value calculations and interference checks that used to be done by hand onto the screen, so the person doing the work is faster and more accurate, and the process leaves data behind. I cannot share exact figures since they are confidential, but when we first saw the results, the efficiency gain surprised everyone.

Which work do you change first?

We start with the points where the people doing the work struggle most. We use every tool ourselves first—“dogfooding”—to filter out what is inconvenient before handing it to the team. We also run AI training for anyone interested, so they can improve their own work themselves.

How do you solve problems?

I keep to an order. First I question the requirements, then boldly delete any step that can go. I simplify what remains, speed it up, and automate last. The most common mistake is automating work that should not exist. And after one lap, I start again from the beginning.

What AI do you use?

We use the best models available at the time. As of September 28, 2026, I develop with Claude Opus 5.5 and GPT-6 Astra, and we are testing Jev for tasks that need fast judgment. Models keep changing, but the principle of always using the best one available stays the same. There is also effectively no limit on usage for work, which is the biggest advantage of this role—you can experiment freely.
