I am writing this for future teammates.

Structure is not trying to be the easiest place to work. It is trying to be one of the highest-rate-of-growth places to work.

That difference matters.

If you want comfort, predictability, narrow responsibility, soft feedback, and a clean separation between the person you are at work and the person you are becoming in life, Structure is probably not the right place.

If you want to build hard things with serious people, tell the truth quickly, own problems completely, sharpen your tools, and grow faster than is comfortable, then this may be exactly the kind of place you have been looking for.

This essay is meant to screen people out as much as it screens people in.

Culture is not office decoration. It is the operating system of the company. It determines what people reward, what they tolerate, what they avoid, what they complain about, what they admire, and what they do when reality gets hard.

At a large institution, most of that is already settled before you arrive. At a startup, especially an early one, culture is still liquid. The first people matter enormously. Each person does not just do work. Each person changes the standard for everyone else.

So I want to be explicit about the culture I am trying to build at Structure.

Where It Comes From

The founders of Structure were shaped by institutions with very high standards.

One side was shaped by MIT and the Broad Institute of MIT and Harvard: places where raw intellect, curiosity, technical depth, and serious scientific ambition are normal. The work is not casual. The people there are not pretending to care about hard problems. They actually care.

The other side was shaped by Jump Trading: a place known for elite engineering, operational discipline, and the relentless search for edge in one of the most competitive environments in the world.

We were also shaped by trading itself.

Trading has a brutal honesty to it. Talk is cheap. PnL does not lie. You can have a beautiful theory, a confident explanation, and a very polished story about why something should have worked. At the end of the day, the result is still the result.

That does not mean every good process wins immediately, or that every loss means the thinking was bad. Markets are noisy. But trading does teach you to respect reality. It punishes ego, denial, and vague reasoning. It rewards people who can look clearly at what happened, update, and improve.

That mindset is core to Structure.

We also carry influence from Hong Kong work culture: respect, diligence, professionalism, and a bias toward getting the job done without turning every inconvenience into a complaint. You can be direct without being rude. You can be demanding without being theatrical. You can hold a high standard and still treat people with respect.

That combination matters to us.

High standards. Low politics. No self-pity.

Truth And Results

I care a lot about truth.

Not truth as a slogan. Truth as a daily operating habit.

What is actually happening? What did the customer actually say? What did the test actually show? What did the metric actually do? What did the code actually ship? What did the candidate actually demonstrate? What did the market actually punish?

Smart people are often very good at explaining away failure. That is dangerous. If you are articulate enough, you can build an elegant story that protects your ego while keeping you stuck.

I do not want that culture.

At Structure, failure is information. Weakness is information. Confusion is information. A bug is information. A missed deadline is information. An awkward customer call is information.

The question is not "How do we make ourselves feel better about this?"

The question is "What is reality telling us, and what are we going to do about it?"

That sounds simple. It is not. It requires people who would rather improve than be protected.

Ownership

Extreme ownership is not a poster on a wall.

It means that when you see a problem, your first instinct is not to ask whose job it is. Your first instinct is to understand what needs to happen and move it forward.

Early-stage startups are not mature institutions. There is no invisible machine around you making everything coherent. There are no perfect processes, no abundant staff functions, no clean boundaries around every responsibility.

We are building the walls while living inside the house.

That requires people who can own the whole problem, not just the slice they were assigned.

I value people who can deliver soup to nuts. They can understand the customer, the product, the implementation, the operational risk, the communication, the edge cases, and the final result. They do not need every detail handed to them. They figure out what matters.

This does not mean everyone does everything forever. Specialization matters. Excellence matters. But early team members need enough range and common sense to create value in the real world, not just inside a tidy job description.

Tool Mastery

I am surprised by how many people use tools every day without ever trying to master them.

They type slowly. They barely know their editor. They use a language without understanding its standard library. They repeat manual workflows that could be automated. They accept friction because they have learned to work around it instead of removing it.

That is not how we want to work.

Tool mastery is a form of respect for your own attention.

The goal is to eliminate as much friction as possible around how work gets done, so more attention can go toward what should be done. If you are constantly fighting your tools, you have less brain available for the actual problem.

At Structure, this matters because the problems are hard. Trading systems, product design, infrastructure, recruiting, operations, and customer work all have enough complexity already. We do not need extra complexity from sloppy tool use.

We want people who keep sharpening the instrument.

Typing speed, editor fluency, debugging skill, command-line comfort, automation, writing clarity, financial literacy, system design, taste in product, understanding what is happening under the hood. None of these are beneath you.

The craft is the job.

Discomfort And Growth

If you want something you do not currently have, you will probably have to become someone you are not currently comfortable being.

That is the part most people skip.

They want the result. They do not want the reconfiguration. They want the title, the money, the skill, the body, the confidence, the network, the taste, the judgment. But they want to keep the habits, fears, excuses, and social environment that produced their current life.

That is not how growth works.

Growth usually feels bad before it feels good. You are clumsy at the new behavior. You are exposed. You have to change your schedule, your standards, your peer group, your sleep, your diet, your learning habits, your communication, your relationship to feedback.

I want people who are willing to do that.

Some of us take athletics seriously for this reason. Training is honest. The body gives feedback. The stopwatch does not care about your explanation. The weight moved or it did not. You showed up or you did not. You recovered well or you did not.

That mentality transfers.

We are not looking for people who worship suffering. We are not interested in burnout theater, reckless urgency, disrespect, or pretending that exhaustion is a strategy. Those things are stupid.

But we are looking for people who understand that meaningful growth is uncomfortable by default.

If you need work to stay inside a comfort zone so you can keep most of your ambition elsewhere, this is not the right environment.

Work As Craft

I do not believe in the usual version of work-life balance.

I do not see work as something separate from life. Work is one of the main ways a person becomes more capable, more disciplined, more useful, more resilient, more honest, and more dangerous in the best sense of the word.

The work works on you more than you work on the work.

That does not mean we ignore health, family, obligations, or recovery. Adults have lives. Strong people manage their lives. The point is different.

The point is that we are not looking for people who view work as a tax they pay in order to fund the "real" parts of life. We are building something hard. We need people who want their work to be a major arena of self-development.

If you are here, become excellent.

Do not coast. Do not hide. Do not optimize for looking busy. Do not wait for someone else to define your ambition.

Ask the bigger question: what could I become if I actually took this seriously?

That is the culture I want.

Direct Feedback, Low Politics

Politics is expensive.

It wastes time, weakens trust, and makes serious people tired. I do not want to wonder whether someone is telling me the truth. I do not want feedback wrapped in five layers of protection. I do not want people managing impressions while problems sit unresolved.

We should say the thing clearly.

Direct feedback is not permission to be careless with people. It is not an excuse for ego, cruelty, or sloppy communication. In fact, direct feedback requires more discipline than vague feedback. You need to be accurate. You need to be fair. You need to separate the person from the behavior. You need to care enough to say what would actually help.

But we should not hide from reality.

People from hard science, trading, competitive athletics, and serious operating environments tend to understand this. Physics does not negotiate. Markets do not care how confident you sounded. The stopwatch does not lie.

When you are not good enough yet, it is obvious.

Good. Now we can improve.

Asking For Help

We help each other.

But asking for help is not the same thing as outsourcing your thinking.

Before you pull someone else into a problem, I expect you to have made a serious attempt. Read the docs. Search the code. Reproduce the issue. Try the obvious paths. Write down what failed. Make the problem smaller. Bring context.

Then ask.

When you do that, helping you becomes rewarding. The person helping you learns from your investigation. The team gets smarter. You become more capable. The conversation starts at a higher level.

When you skip that work, you are just transferring your burden to someone else.

That is not ownership.

Urgency

Startups run on urgency.

Not panic. Not chaos. Not motion for its own sake.

Urgency means you understand that time is real. The market changes. Candidates have options. Customers lose patience. Competitors ship. Opportunities decay. Energy fades if nothing moves.

At Structure, I want people who move.

They do not need to be chased. They do not need a manager to manufacture pressure. They understand what matters, make decisions with incomplete information, and keep pushing the work toward reality.

Speed without judgment is dangerous. Judgment without speed is academic.

We need both.

What You Get

This is a demanding culture. It should be.

But the upside is real.

You get unusually fast growth. You get ownership before most companies would trust you with it. You get to work with people who care about the craft. You get exposure to trading systems, product, AI, infrastructure, crypto markets, and company-building at the same time.

You get a chance to build something meaningful with people who are trying to become excellent.

You get financial upside if we win.

And maybe most importantly, you get an environment that will not let you comfortably become mediocre.

That is not for everyone. It is not supposed to be.

Who Should Not Join

Do not join Structure if you want a cushy work experience.

Do not join if you need every responsibility to be perfectly scoped before you act.

Do not join if you dislike direct feedback.

Do not join if you are not willing to push yourself into uncomfortable growth.

Do not join if you want to protect most of your energy for other areas of life and treat work as a stable background process.

Do not join if you are brilliant but low ownership.

Brilliance is not enough here.

I would rather work with someone slightly less brilliant who tells the truth, owns the problem, learns fast, and gets the job done.

Who Should Join

Join if you want to be pushed.

Join if you want to build real things with real consequences.

Join if you want low politics, direct feedback, high standards, and serious ownership.

Join if you like tools, systems, markets, craft, and the feeling of becoming sharper because the work demanded it.

Join if you are respectful, diligent, intense, curious, and hard to discourage.

Join if you are willing to trade comfort for growth.
