Careers – Software Engineering
Build systems that trade profitably
We are a high-frequency trading firm. Our goal isn’t just shaving microseconds, it’s trading profitably. You get high leverage, direct feedback, and absolute ownership.
Engineering at Wincent is driven by the bottleneck that matters most
The work changes based on what is holding us back. We focus on the limiting factor, whether that is architecture, tooling, infrastructure, exchange connectivity, or performance-critical code.
How we think about it
We do not optimize for speed alone. A change matters when it improves trading outcomes, reduces risk, or makes the system easier to reason about under pressure.
Sometimes the right answer is to go deeper on latency. Sometimes it is to simplify a system, redesign an interface, or build better tools.
You cannot make good technical tradeoffs in isolation. We expect you to understand how the pieces fit together and solve the right problem.
Where the constraint tends to live
In practice, the work tends to concentrate in a few places: production systems, architecture, infrastructure, tooling, and performance-critical code. Engineers follow the constraint, not the org chart.
Trading paths & production systems
When execution, capacity, reliability, or observability on the hot path is what limits the business.
Architecture & the real constraint
When the hard part is figuring out what to optimize or unblocking flow by simplifying design.
Markets & connectivity
When exchange behavior, venue integration, or market-facing plumbing is the bottleneck.
Tooling & leverage
When better tools help engineers or traders move faster with fewer mistakes.
How we work
Small teams. Direct feedback. Real ownership.
Engineers work close to the systems, the traders, and the decisions their code affects.
We say things as they are. We prefer direct communication over long reporting chains. If there is a problem, talk to the people involved and fix it.
Feedback is direct and specific. We judge the mistake, not the person. A good decision can improve the company. A bad decision can lose money. We care about fixing the issue, not protecting the ego.
Ownership means staying with the problem until it creates value. A project is not shipped when the code is merged. It is shipped when the system is better.
No long reporting chains
Talk to the people involved and fix it, rather than routing it upward.
Close to trading
Understand how your work affects execution, reliability, latency, or decision logic.
Direct feedback
Bad decisions get challenged. Good decisions get copied. Both happen openly.
Ownership until value
You own the outcome, not just the ticket, branch, or deployment.
We hire problem solvers
A finance or trading background is not required. We look for people who reason across complex systems and raise the bar. We hire for ownership, judgment, and shipping. We care less about a CV full of titles and more about what you built, how much you owned, and how you moved the day it broke.
Trading Core Engineering
Build exchange connectivity, order execution, and real-time market data systems where correctness and latency both matter.
Algo Engineering
Turn quant ideas into production trading logic. Work with researchers, test behavior, and ship systems that affect live PnL.
Infrastructure & DevOps
Improve global connectivity, observability, deployment, and reliability for a 24/7 trading system.
Tooling & DevEx
Build internal tools that help traders, quants, finance, and operations move faster with fewer mistakes.

I bet with @John I will hold plank longer than him for 10 euro. He is weak. This is free money

@Memelord is betting @Steven that compiling platform cargo build --release will not eat more than 5GB of RAM. 5 euro.
The best way to understand the company is to hear directly from the team
Engineers here describe the work as high-agency, technically demanding, and closely tied to business outcomes. They are expected to own problems, work across functions, and help find the solution that actually matters. They also describe the culture in practical terms: direct feedback, low politics, and openness that depends on people being clear with each other.
“Our goal is not to shave off some miniscule amounts of time. Our main goal is to trade profitably. If it means we need to redefine our core algorithm and the decision logic, we will do that.”
“I get a lot more agency here. I am expected to really own my problems. And not only expected, but allowed to. Engineers get a lot of leverage.”
“People here, they say things as they are. We are not trying to beat around the bush when there’s a problem, we are trying to talk about it.”
“The god emperor of engineering would be someone who can take a look at the whole system and find the bottleneck. Find the thing where it makes the most sense to optimize.”
