Software Engineering Trainee

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 in a high-intensity, high-upside environment.

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 back-end 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/back-end 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.
