Overview
Structure.fi is a venture-backed startup building the default platform for AI-designed algorithmic trading strategies in crypto.
We’re looking for elite software engineers who want to work onsite, full-time, Sunday–Thursday, in a high-intensity, high-upside environment.
This is not a cushy remote job, and it’s not a French-corporate-style CDI.
You’ll join a tiny, senior team (~7 people) with founders from MIT and Jump Trading, backed by Polychain Capital, to build real trading infrastructure: execution, risk, monitoring – not toy retail dashboards.
If you’re optimizing for growth, impact, and upside (not “balance”), and you like the idea of helping build a billion‑dollar company in ~18 months, keep reading.
Key responsibilities
Design, build, and operate backend and infrastructure for AI-driven algorithmic trading in crypto.
Work closely with founders on:
Low-latency execution systems
Data pipelines and model integration
Risk and monitoring infrastructure in production
Ship real features to production fast, iterate based on live performance, and own your systems end-to-end.
Help define and enforce engineering standards (code quality, testing, performance, observability).
Collaborate directly with a small, high-caliber team in the office every day.
Contribute to technical decision-making on architecture, tools, and tradeoffs.
Embrace startup intensity: nights and weekends when objectives require it. Not for vanity, but to win.
Qualifications
We care more about capability and trajectory than fancy titles. As a benchmark, you likely have:
Strong programming skills in at least one systems/backend language (e.g. Rust, C++, Go, Java, or similar).
Experience building production systems where correctness, performance, and reliability matter.
Solid understanding of:
Data structures & algorithms
Concurrency and distributed systems basics
Systems performance (profiling, optimization)
Comfort working close to:
Infra / dev tooling / distributed systems, and/or
Low-latency / trading / real-time systems
Bonus points (not required, but strong signals):
Experience in trading, quant, HFT, or financial infrastructure.
Experience with crypto (exchanges, wallets, DeFi primitives).
Experience with AI/ML systems in production.
Mindset (non‑negotiable):
You want intensity and accountability. You’d rather be stretched than bored.
You are competitive: you like to win, you like to get better, you like hard problems.
You communicate clearly: you can explain complex technical ideas in simple language.
You think like an owner, not an employee. You care about the outcome, not just your ticket queue.
Logistics:
Onsite in Paris, in the office every workday.
You can legally work as an independent contractor in France (micro‑entrepreneur / auto‑entrepreneur or equivalent), or are willing to set that up.
What we offer
A B2B freelance engagement with a high-caliber, venture-backed team (Polychain, MIT, Jump).
A very competitive daily rate, invoiced monthly by the contractor under their own independent legal status.
A 3-month initial evaluation phase to determine whether both sides want to continue the collaboration long-term.
After a successful evaluation period, Structure.fi may choose—at its discretion—to offer:
Access to onsite meals for convenience.
Optional performance-based incentives defined contractually.
Potential equity participation through a separate agreement.
Case-by-case administrative or relocation support for contractors who want to be closer to the office.
No traditional employment benefits are provided, as this is not an employment relationship.
